Each of the electronic devices 102 and 104 may be a device of a same type as, or a different type, from the electronic device 101. According to an embodiment, all or some of operations to be executed at the electronic device 101 may be executed at one or more of the external electronic devices 102, 104, or 108. For example, if the electronic device 101 should perform a function or a service automatically, or in response to a request from a user or another device, the electronic device 101, instead of, or in addition to, executing the function or the service, may request the one or more external electronic devices to perform at least part of the function or the service. The one or more external electronic devices receiving the request may perform the at least part of the function or the service requested, or an additional function or an additional service related to the request, and transfer an outcome of the performing to the electronic device 101. The electronic device 101 may provide the outcome, with or without further processing of the outcome, as at least part of a reply to the request. To that end, a cloud computing, distributed computing, or client-server computing technology may be used, for example.

FIG. 2 is a block diagram 200, according to various embodiments, illustrating the display device 160 including a touch layer having an opening. Referring to FIG. 2, the display device 160 may include a display 210 and a display driver integrated circuit (DDI) 230 to control the display 210. The DDI 230 may include an interface module 231, memory 233 (e.g., buffer memory), an image processing module 235, or a mapping module 237. The DDI 230 may receive image information that contains image data or an image control signal corresponding to a command to control the image data from another component of the electronic device 101 via the interface module 231. For example, according to an embodiment, the image information may be received from the processor 120 (e.g., the main processor 121 (e.g., an application processor)) or the auxiliary processor 123 (e.g., a graphics processing unit) operated independently from the function of the main processor 121. The DDI 230 may communicate, for example, with touch circuitry 150 or the sensor module 176 via the interface module 231. The DDI 230 may also store at least part of the received image information in the memory 233, for example, on a frame by frame basis. The image processing module 235 may perform pre-processing or post-processing (e.g., adjustment of resolution, brightness, or size) with respect to at least part of the image data. According to an embodiment, the pre-processing or post-processing may be performed, for example, based at least in part on one or more characteristics of the image data or one or more characteristics of the display 210. The mapping module 237 may generate a voltage value or a current value corresponding to the image data pre-processed or post-processed by the image processing module 235. According to an embodiment, the generating of the voltage value or current value may be performed, for example, based at least in part on one or more attributes of the pixels (e.g., an array, such as an RGB stripe or a pentile structure, of the pixels, or the size of each subpixel). At least some pixels of the display 210 may be driven, for example, based at least in part on the voltage value or the current value such that visual information (e.g., a text, an image, or an icon) corresponding to the image data may be displayed via the display 210.

According to an embodiment, the display device 160 may further include the touch circuitry 250. The touch circuitry 250 may include a touch sensor 251 and a touch sensor IC 253 to control the touch sensor 251. The touch sensor IC 253 may control the touch sensor 251 to sense a touch input or a hovering input with respect to a certain position on the display 210. To achieve this, for example, the touch sensor 251 may detect (e.g., measure) a change in a signal (e.g., a voltage, a quantity of light, a resistance, or a quantity of one or more electric charges) corresponding to the certain position on the display 210. The touch circuitry 250 may provide input information (e.g., a position, an area, a pressure, or a time) indicative of the touch input or the hovering input detected via the touch sensor 251 to the processor 120. According to an embodiment, at least part (e.g., the touch sensor IC 253) of the touch circuitry 250 may be formed as part of the display 210 or the DDI 230, or as part of another component (e.g., the auxiliary processor 123) disposed outside the display device 160.

According to an embodiment, the display device 160 may further include at least one sensor (e.g., a fingerprint sensor, an iris sensor, a pressure sensor, or an illuminance sensor) of the sensor module 176 or a control circuit for the at least one sensor. In such a case, the at least one sensor or the control circuit for the at least one sensor may be embedded in one portion of a component (e.g., the display 210, the DDI 230, or the touch circuitry 150)) of the display device 160. For example, when the sensor module 176 embedded in the display device 160 includes a biometric sensor (e.g., a fingerprint sensor), the biometric sensor may obtain biometric information (e.g., a fingerprint image) corresponding to a touch input received via a portion of the display 210. As another example, when the sensor module 176 embedded in the display device 160 includes a pressure sensor, the pressure sensor may obtain pressure information corresponding to a touch input received via a partial or whole area of the display 210. According to an embodiment, the touch sensor 251 or the sensor module 176 may be disposed between pixels in a pixel layer of the display 210, or over or under the pixel layer.

According to one embodiment, the display 510 is formed of multiple pixels, and the pixels may include multiple subpixels (Ps). The display 510 may include multiple gate lines (GLs) (e.g. GL1 to GLn) and multiple data lines (DLs) (e.g. DL1 to DLm), which cross each other. A subpixel (P) may be formed in a region in which a gate line (GL) crosses a data line (DL). Each subpixel (P) may include an organic light-emitting diode (OLED) and at least one driving circuit for driving the organic light-emitting diode.

According to various embodiments, the display region 511 may include at least one opening 511a (e.g. the first openings 331 or the second opening 332 in FIG. 3) in which at least one sensor (e.g. a camera sensor, a proximity sensor, an infrared sensor, etc.) is disposed (or through which the sensor is visually exposed). According to one embodiment, the opening 511a surrounded by the display region 511 may be shaped in a form corresponding to the form (e.g. the shape and the size) of each sensor such that the corresponding sensor is disposed therein (or exposed therethrough).

The driving circuit provided in each subpixel (P) may include at least one switch (e.g. a thin film transistor (TFT)) (hereinafter, referred to as a “thin film transistor”), at least one capacitor (e.g. a storage capacitor (CST), or a light-emitting element (e.g. an organic light-emitting diode).

The at least one thin film transistor (TFT) may charge a capacitor with a data voltage supplied from a data line (DL) in response to a scan signal supplied from a gate line (GL). The at least one thin film transistor (TFT) may control the amount of current supplied to an organic light-emitting diode according to the data voltage with which the capacitor has been charged.

FIG. 6 illustrates a display, having a wiring structure for connecting touch electrodes around an opening to each other, according to various embodiments. Referring to FIG. 6, the display region 311 (e.g. the display region 511 in FIG. 5) of the display 310 (e.g. the display 510) may include: multiple first touch lines arranged in the Y-axis direction; and multiple second touch lines arranged in the X-axis direction while crossing the first touch lines. At least one of the first touch lines and at least one of the second touch lines may be arranged around the first opening 331 and the second opening 332. When a surrounding part 600 surrounding the second opening 332 is enlarged and viewed as illustrated, a (1-1)th touch line 611, a (1-2)th touch line 612, and a (1-3)th touch line 613 may be arranged in the X-axis direction in the surrounding part 600. The pitch between adjacent touch lines in the X-axis direction may be constant. For example, a (1-1)th pitch 621 may be equal to a (1-2)th pitch 622. In another example, the (1-1)th pitch 621 may be different from the (1-2)th pitch 622. In the surrounding part 600, a (2-1)th touch line 631, a (2-2)th touch line 632, and a (2-3)th touch line 633 may be arranged in the Y-axis direction while crossing the (1-1)th touch line 611, the (1-2)th touch line 612, and the (1-3)th touch line 613. The pitch between adjacent touch lines in the Y-axis direction may be constant. For example, a (2-1)th pitch 641 may be equal to a (2-2)th pitch 642. In another example, the (2-1)th pitch 641 may be different from the (2-2)th pitch 642. A touch sensor IC (e.g. the touch sensor IC 253 in FIG. 2) may sequentially output a signal (e.g. a scan signal) to the (2-1)th touch line 631, the (2-2)th touch line 632, and the (2-3)th touch line 633. The touch sensor IC may sense a touch input or a hovering input to a particular position in the surrounding part 600 by measuring a change (e.g. capacitance) in the signal via the (1-1)th touch line 611, the (1-2)th touch line 612, and the (1-3)th touch line 613.

According to various embodiments, touch electrodes around an opening may be electrically connected via a connection wire formed around the opening. According to one embodiment, the second opening 332 may be formed at a point 651 where the (1-2)th touch line 612 crosses the (2-1)th touch line 631. For example, the second opening 332 may be formed such that the center of the second opening 332 is close to the point 651. The dead space 342 (e.g. a printing region) may be formed around the second opening 332. Thus, in the (1-2)th touch line 612 including a first touch electrode 612a and a second touch electrode 612b, a part of the first touch electrode 612a and a part of the second touch electrode 612b may be lost due to the second opening 332. As a result, the first touch electrode 612a and the second touch electrode 612b may be electrically disconnected from each other. However, the first touch electrode 612a and the second touch electrode 612b may be electrically connected to each other via a first connection wire 661 disposed around the second opening 332 and bypassing the second opening 332. In the (2-1)th touch line 631 including a third touch electrode 631a and a fourth touch electrode 631b, a part of the third touch electrode 631a and a part of the fourth touch electrode 631b may be lost due to the second opening 332. As a result, the third touch electrode 631a and the fourth touch electrode 631b may be electrically disconnected from each other. However, the third touch electrode 631a and the fourth touch electrode 631b may be electrically connected to each other via a second connection wire 662 disposed around the second opening 332 and bypassing the second opening 332.

According to various embodiments, touch electrodes around an opening may be electrically connected via multiple connection wires formed around the opening. For example, the first touch electrode 612a may be electrically connected to the second touch electrode 612b via the first connection wire 661 bypassing the second opening 332 in the counterclockwise direction and a third connection wire 663 bypassing the second opening 332 in the clockwise direction. The third touch electrode 631a may be electrically connected to the fourth touch electrode 631b via the second connection wire 662 bypassing the second opening 332 in the counterclockwise direction and a fourth connection wire 664 bypassing the second opening 332 in the clockwise direction.

According to various embodiments, at least some of the connection wires may be arranged inside the dead space 342. For example, the first connection wire 661, the second connection wire 662, the third connection wire 663, and/or the fourth connection wire 664 may be positioned inside the dead space 342.

According to various embodiments, a connection wire (e.g. the first connection wire 661, the second connection wire 662, the third connection wire 663, and/or the fourth connection wire 664) may be formed of one of metal, metal mesh, silver nano (AgNW), graphene, carbon nanotubes, and indium tin oxide (ITO) or a combination of at least two thereof.

According to various embodiments, a touch electrode may be a metal, a metal mesh, or a combination thereof, and the shape of the touch electrode may be a diamond shape, as illustrated in FIG. 6. However, the touch electrode is not limited to having a diamond shape, but may have various shapes such as a rectangular shape.

FIG. 7A illustrates a display, having a wiring structure for compensating touch sensitivity around an opening, according to various embodiments. FIG. 7B shows the surrounding part around the opening in FIG. 7A in an enlarged state. For the convenience of description, elements overlapping those in FIG. 6 will be described briefly, or a description thereof will be omitted. Referring to FIG. 7A, in a surrounding part 700 (e.g. the surrounding part 600 in FIG. 6), a (1-1)th touch line 711, a (1-2)th touch line 712, and a (1-3)th touch line 713 may be arranged in the X-axis direction, and a (2-1)th touch line 731, a (2-2)th touch line 732, and a (2-3)th touch line 733 may be arranged in the Y-axis direction while crossing the (1-1)th touch line 711, the (1-2)th touch line 712, and the (1-3)th touch line 713. A first touch electrode 712a and a second touch electrode 712b included in the (1-2)th touch line 712 may be arranged around the second opening 332, and may be electrically connected to each other via a first connection wire 761 bypassing the second opening 332. A third touch electrode 731a and a fourth touch electrode 731b included in the (2-1)th touch line 731 may be arranged around the second opening 332, and may be electrically connected to each other via a second connection wire 762 bypassing the second opening 332.

According to various embodiments, a compensation pattern for compensating touch sensitivity (e.g. mutual capacitance sensitivity) around an opening may be formed around the opening. A part of each of the first touch electrode 712a, the second touch electrode 712b, the third touch electrode 731a, and the fourth touch electrode 731b is lost due to the second opening 332. Thus, touch sensitivity around the second opening 332 may be reduced. The first connection wire 761 and the second connection wire 762 are patterns for minimizing a reduction in touch sensitivity around the second opening 332, and may be formed around the second opening 332. For example, the first connection wire 761 may extend, in the dead space 342, to be longer than the first connection wire 661 in FIG. 6, and at least a part of the first connection wire 761 may extend in the dead space 342 while being thicker than the first connection wire 661 in FIG. 6. In other words, referring to FIG. 7B, the first connection wire 761 may include: a first part 761a connecting the first touch electrode 712a to the second touch electrode 712b; a second part 761b elongated from the first part 761a in the dead space 342; and a third part 761c which is thick and extends from the first part 761a in the dead space 342. The second connection wire 762 may extend, in the dead space 342, to be longer than the second connection wire 662 in FIG. 6. At least a part of the second connection wire 762 may extend in the dead space 342 while being thicker than the second connection wire 662 in FIG. 6. In other words, referring to FIG. 7B, the second connection wire 762 may include: a first part 762a connecting the third touch electrode 731a to the fourth touch electrode 731b; a second part 762b elongated from the first part 762a in the dead space 342; and a third part 762c which is thick and extends from the first part 762a in the dead space 342.

FIG. 8A illustrates a display, having a wiring structure for compensating touch sensitivity around an opening, according to various embodiments. FIG. 8B shows a surrounding part around the opening in FIG. 8A in an enlarged state. For the convenience of description, elements overlapping those in FIG. 6 will be described briefly, or a description thereof will be omitted. Referring to FIG. 8A, in a surrounding part 800 (e.g. the surrounding part 600 in FIG. 6), a (1-1)th touch line 811, a (1-2)th touch line 812, and a (1-3)th touch line 813 may be arranged in the X-axis direction, and each of a (2-1)th touch line 831, a (2-2)th touch line 832, and a (2-3)th touch line 833 may be arranged in the Y-axis direction while crossing the (1-1)th touch line 811, the (1-2)th touch line 812, and the (1-3)th touch line 813. A first touch electrode 812a and a second touch electrode 812b included in the (1-2)th touch line 812 may be arranged around the second opening 332. The first touch electrode 812a may be electrically connected to the second touch electrode 812b via a first connection wire 861 bypassing the second opening 332 in the counterclockwise direction and a third connection wire 863 bypassing the second opening 332 in the clockwise direction. A third touch electrode 831a may be electrically connected to a fourth touch electrode 831b via a second connection wire 862 bypassing the second opening 332 in the counterclockwise direction and a fourth connection wire 864 bypassing the second opening 332 in the clockwise direction.

According to various embodiments, a compensation pattern for compensating touch sensitivity around an opening may be formed around the opening. In one embodiment, a part of each of the first touch electrode 812a, the second touch electrode 812b, the third touch electrode 831a, and the fourth touch electrode 831b is lost due to the second opening 332. Thus, the touch sensitivity around the second opening 332 may be reduced. The first connection wire 861, the second connection wire 862, the third connection wire 863, and the fourth connection wire 864 are patterns for minimizing the reduction of the touch sensitivity around the second opening 332, and may be formed around the second opening 332. Describing one embodiment with reference to FIG. 8B, the first connection wire 861 may include: a first part 861a connecting the first touch electrode 812a to the second touch electrode 812b; and a second part 861b extending from the first part 861a to be adjacent to the fourth touch electrode 831b beyond the dead space 342. The second connection wire 862 may include: a first part 862a connecting the third touch electrode 831a to the fourth touch electrode 831b; and a second part 862b extending from the first part 862a to be adjacent to the second touch electrode 812b beyond the dead space 342. The third connection wire 863 may include: a first part 863a connecting the first touch electrode 812a to the second touch electrode 812b; and a second part 863b extending from the first part 863a to be adjacent to the third touch electrode 831a beyond the dead space 342. The fourth connection wire 864 may include: a first part 864a connecting the third touch electrode 831a to the fourth touch electrode 831b; and a second part 864b extending from the first part 864a to be adjacent to the first touch electrode 812a beyond the dead space 342.

According to various embodiments, a connection wire (e.g. the first connection wire 861, the second connection wire 862, the third connection wire 863, and/or the fourth connection wire 864) may be formed in a layer different from that of touch electrodes around an opening. For example, the layer in which the connection wire is formed may be disposed on or beneath a layer in which the touch electrodes are formed, and the connection wire layer may be electrically connected to the touch electrode layer through a via.

FIG. 9 illustrates a display having a wiring structure for connecting touch electrodes around an opening to each other, according to various embodiments. For the convenience of description, elements overlapping those in FIG. 6 will be described briefly, or a description thereof will be omitted. Referring to FIG. 9, in a surrounding part 900 (e.g. the surrounding part 600 in FIG. 6), a (1-1)th touch line 911, a (1-2)th touch line 912, and a (1-3)th touch line 913 may be arranged in the X-axis direction, and a (2-1)th touch line 931, a (2-2)th touch line 932, and a (2-3)th touch line 933 may be arranged in the Y-axis direction while crossing the (1-1)th touch line 911, the (1-2)th touch line 912, and the (1-3)th touch line 913.

According to various embodiments, touch electrodes around an opening may be electrically connected to each other via a connection wire formed around the opening. In one embodiment, the second opening 332 may be formed such that at least a part of each of the touch electrodes is lost due to the second opening 332. For example, when the second opening 332 is formed such that the center of the second opening 332 is close to or is substantially aligned with the center of a touch electrode included in the (1-2)th touch line 912, the touch electrode may be lost. Thus, a first touch electrode 912a and a second touch electrode 912b are electrically disconnected from each other at the location of the lost touch electrode therebetween. However, the first touch electrode 912a may be electrically connected to the second touch electrode 912b via a first connection wire 961 disposed around the second opening 332 and bypassing the second opening 332. In the (2-1)th touch line 931, a third touch electrode 931a and a fourth touch electrode 931b may be partially lost due to the second opening 332 and the dead space 342 formed therearound. Thus, the third touch electrode 931a may be electrically disconnected from the fourth touch electrode 931b. However, the third touch electrode 931a may be electrically connected to the fourth touch electrode 931b via a second connection wire 962 disposed around the second opening 332. In the (2-2)th touch line 932, a fifth touch electrode 932a and a sixth touch electrode 932b may be partially lost due to the second opening 332 and the dead space 342. Thus, the fifth touch electrode 932a may be electrically disconnected from the sixth touch electrode 932b. However, the fifth touch electrode 932a may be electrically connected to the sixth touch electrode 932b via a third connection wire 963 disposed around the second opening 332.

According to various embodiments, a connection wire may be formed in a dead space. For example, the first connection wire 961, the second connection wire 962, and/or the third connection wire 963 may be positioned in the dead space 342.

According to various embodiments, a connection wire (e.g. the first connection wire 961, the second connection wire 962, and/or the third connection wire 963) may be formed of a metal or a metal mesh. Alternatively, a connection wire may be formed of a combination of a metal and a metal mesh.

FIG. 10 illustrates a display having a wiring structure for compensating touch sensitivity around an opening according to various embodiments. For the convenience of description, elements overlapping those in FIG. 9 will be described briefly, or a description thereof will be omitted. Referring to FIG. 10, in a surrounding part 1000 (e.g. the surrounding part 900 in FIG. 9), a (1-1)th touch line 1011, a (1-2)th touch line 1012, and a (1-3)th touch line 1013 may be arranged in the X-axis direction, and a (2-1)th touch line 1031, a (2-2)th touch line 1032, and a (2-3)th touch line 1033 may be arranged in the Y-axis direction while crossing the (1-1)th touch line 1011, the (1-2)th touch line 1012, and the (1-3)th touch line 1013.

FIG. 11 illustrates a display having a wiring structure for compensating touch sensitivity around an opening according to various embodiments. For the convenience of description, elements overlapping those in FIG. 9 will be described briefly, or a description thereof will be omitted. Referring to FIG. 11, in a surrounding part 1100 (e.g. the surrounding part 900 in FIG. 9), a (1-1)th touch line 1111, a (1-2)th touch line 1112, and a (1-3)th touch line 1113 may be arranged in the X-axis direction, and a (2-1)th touch line 1131, a (2-2)th touch line 1132, and a (2-3)th touch line 1133 may be arranged in the Y-axis direction while crossing the (1-1)th touch line 1111, the (1-2)th touch line 1112, and the (1-3)th touch line 1113.

According to various embodiments, a compensation pattern for compensating touch sensitivity around an opening may be formed around the opening. In one embodiment, when the second opening 332 is formed such that the center of the second opening 332 is close to or is substantially aligned with the center of a touch electrode included in the (1-2)th touch line 1112, and when the dead space 342 is formed around the second opening 332, at least a part of the touch electrode may be lost. For example, the remaining part of the touch electrode, except for a part 1112c thereof, is lost, and thus, in the (1-2) th touch line 1112, a first touch electrode 1112a may be electrically disconnected from a second touch electrode 1112b at the location of the lost part therebetween, and the touch sensitivity around the second opening 332 may be reduced. A first connection wire 1161 is a pattern for minimizing the reduction in touch sensitivity around the second opening 332, and may be formed around the second opening 332. For example, the first connection wire 1161 may include: a first part 1161a, formed in the dead space 342 and having the shape of a ring surrounding the second opening 332; a second part 1161b, electrically connected to the first touch electrode 1112a and extending from the first part 1161a to be adjacent to a third touch electrode 1131a and a fourth touch electrode 1131b in the (2-1)th touch line 1131 beyond the dead space 342; and a third part 1161c, electrically connected to the second touch electrode 1112b and extending from the first part 1161a to be adjacent to a fifth touch electrode 1132a and a sixth touch electrode 1132b in the (2-2)th touch line 1132 beyond the dead space 342.

FIG. 12 illustrates a display having a wiring structure for compensating touch sensitivity around an opening according to various embodiments. For the convenience of description, elements overlapping those in FIG. 6 will be described briefly, or a description thereof will be omitted. Referring to FIG. 12, in a surrounding part 1200 (e.g. the surrounding part 600 in FIG. 6), a (1-1)th touch line 1211, a (1-2)th touch line 1212, and a (1-3)th touch line 1213 may be arranged in the X-axis direction, and each of a (2-1)th touch line 1231, a (2-2)th touch line 1232, and a (2-3)th touch line 1233 may be arranged in the Y-axis direction while crossing the (1-1)th touch line 1211, the (1-2)th touch line 1212, and the (1-3)th touch line 1213.

According to one embodiment, when the second opening 332 and the dead space 342 surrounding the same are formed such that a first point 1271, at which the (1-1)th touch line 1211 crosses the (2-1)th touch line 1231, a second point 1272, at which the (1-2)th touch line 1212 crosses the (2-1)th touch line 1231, a third point 1273, at which the (1-1)th touch line 1211 crosses the (2-2)th touch line 1232, and a fourth point 1274, at which the (1-2)th touch line 1212 crosses the (2-2)th touch line 1232, are not lost, Portions of the touch electrodes may be lost and thus touch sensitivity may be reduced, but the touch electrodes may not be electrically disconnected from each other. For example, when the second opening 332 and the dead space 342 are formed, a part of a first touch electrode 1211a of the (1-1)th touch line 1211, a part of a second touch electrode 1212a of the (1-2)th touch line 1212, a part of a third touch electrode 1231a of the (2-1)th touch line 1231, and a part of a fourth touch electrode 1232a of the (2-2)th touch line 1232 may be lost. However, even though the second opening 332 and the dead space 342 are formed, the touch electrodes of the (1-1)th touch line 1211 may not be electrically disconnected from each other, the touch electrodes of the (1-2)th touch line 1212 may not be electrically disconnected from each other, the touch electrodes of the (2-1)th touch line 1231 may not be electrically disconnected from each other, and the touch electrodes of the (2-2)th touch line 1232 may not be electrically disconnected from each other.

According to various embodiments, at least one compensation pattern for compensating touch sensitivity around an opening may be formed in a dead space around the opening. According to one embodiment, a first compensation pattern 1261 may be formed in the dead space 342 adjacent to the first touch electrode 1211a, a second compensation pattern 1262 may be formed in the dead space 342 adjacent to the second touch electrode 1212a, a third compensation pattern 1263 may be formed in the dead space 342 adjacent to the third touch electrode 1231a, and a fourth compensation pattern 1264 may be formed in the dead space 342 adjacent to the fourth touch electrode 1232a.

According to various embodiments, the electrode nonuse rate of a touch electrode partially lost due to an opening may be configured to be lower than the electrode nonuse rate of another touch electrode which is not lost due to the opening, and thus touch sensitivity around the opening may be compensated. For example, the electrode nonuse rate may signify the ratio of a part per unit area (known as a “dummy”) which is not used as an electrode. For example, before being lost, when a first touch electrode and a second touch electrode have the same area and the dummy of the first touch electrode is smaller than the dummy of the second touch electrode, this may indicate that the electrode nonuse rate of the first touch electrode is lower than the electrode nonuse rate of the second touch electrode. The nonuse rate of at least one of touch electrodes partially lost due to an opening (e.g. at least one of the touch electrodes 612a, 612b, 631a, and 631b in FIG. 6, at least one of the touch electrodes 712a, 712b, 731a, and 731b in FIG. 7A and FIG. 7B, at least one of the touch electrodes 812a, 812b, 831a, and 831b in FIG. 8A and FIG. 8B, at least one of the touch electrodes 931a, 931b, 932a, and 932b in FIG. 9, at least one of the touch electrodes 1031a, 1031b, 1032a, and 1032b in FIG. 10, at least one of the touch electrodes 1131a, 1131b, 1132a, and 1132b in FIG. 11, and at least one of the touch electrodes 1211a, 1212a, 1231a, and 1232a in FIG. 12) may be configured to be lower than the nonuse rate of other touch electrodes (e.g. unlost touch electrodes).

FIG. 13 illustrates a display having a wiring structure for compensating touch sensitivity around an opening according to various embodiments. For the convenience of description, elements overlapping those in FIG. 6 will be described briefly, or a description thereof will be omitted. Referring to FIG. 13, in a surrounding part 1300 (e.g. the surrounding part 600 in FIG. 6), a (1-1)th touch line 1311, a (1-2)th touch line 1312, a (1-3)th touch line 1313, and a (1-4)th touch line 1314 may be arranged in the X-axis direction, and a (2-1)th touch line 1331, a (2-2)th touch line 1332, and a (2-3)th touch line 1333 may be arranged in the Y-axis direction while crossing the (1-1)th touch line 1311, the (1-2)th touch line 1312, the (1-3)th touch line 1313, and the (1-4)th touch line 1314. The second opening 332 and the dead space 342 surrounding the same may be formed in the surrounding part 1300. A first part 1312a of the (1-2)th touch line 1312 may be electrically connected to a second part 1312b thereof via a first connection wire 1361 formed in the dead space 342. A first part 1313a of the (1-3)th touch line 1313 may be electrically connected to a second part 1313b thereof via a second connection wire 1362 in the dead space 342. Further, a first part 1332a of the (2-2)th touch line 1332 may be electrically connected to a second part 1332b thereof via a third connection wire 1363 formed in the dead space 342.

According to various embodiments, the touch electrode resolution of a surrounding part (e.g. the surrounding part 1300) may be configured to be higher than the touch electrode resolution outside the surrounding part, and thus the touch sensitivity of the surrounding part, in which an opening is formed, may be compensated. For example, the touch electrode resolution (hereinafter, referred to in brief as “resolution”) may refer to the number of touch electrodes per unit area. For example, if a first area is the same size as a second area but the number of touch electrodes positioned in the first area is greater than the number of touch electrodes positioned in the second area, this may signify that the resolution of the first area is higher than the resolution of the second area. According to one embodiment, a pitch 1391 between adjacent touch lines arranged in the X-axis direction while passing through the surrounding part 1300 may be configured to be narrower than a pitch 1392 between adjacent touch lines which are arranged in the X-axis direction and at least one of which does not pass through the surrounding part 1300. A pitch 1393 between adjacent touch lines arranged in the Y-axis direction while passing through the surrounding part 1300 may be configured to be narrower than a pitch 1394 between adjacent touch lines which are arranged in the Y-axis direction and at least one of which does not pass through the surrounding part 1300. Thus, the resolution of the surrounding part 1300 may be configured to be higher than the resolution of a part 1380 outside the surrounding part.

According to various embodiments, a touch sensor IC (e.g. the touch sensor IC 253 in FIG. 2) may compensate touch sensitivity around an opening by controlling a switch for interconnecting adjacent touch lines arranged in the same direction while passing through a surrounding part (e.g. the surrounding part 1300). According to one embodiment, a touch circuit (e.g. the touch circuit 250 in FIG. 2) may include: a first switch 1341 connected between the (1-1)th touch line 1311 and the (1-2)th touch line 1312; a second switch 1342 connected between the (1-3)th touch line 1313 and the (1-4)th touch line 1314; a third switch 1343 connected between the (2-1)th touch line 1331 and the (2-2)th touch line 1332; and a fourth switch 1344 connected between the (2-2)th touch line 1332 and the (2-3)th touch line 1333. The touch sensor IC may electrically connect the (1-1)th touch line 1311 to the (1-2)th touch line 1312 by controlling the first switch 1341 to be closed, and may release the electrical connection between the (1-1)th touch line 1311 and the (1-2)th touch line 1312 by controlling the first switch 1341 to be opened. The touch sensor IC may electrically connect the (1-3)th touch line 1313 to the (1-4)th touch line 1314 by controlling the second switch 1342 to be closed, and may release the electrical connection between the (1-3)th touch line 1313 and the (1-4)th touch line 1314 by controlling the second switch 1342 to be opened. The touch sensor IC may electrically connect the (2-1)th touch line 1331 to the (2-2)th touch line 1332 by controlling the third switch 1343 to be closed, and may release the electrical connection between the (2-1)th touch line 1331 and the (2-2)th touch line 1332 by controlling the third switch 1343 to be opened. The touch sensor IC may electrically connect the (2-2)th touch line 1332 to the (2-3)th touch line 1333 by controlling the fourth switch 1344 to be closed, and may release the electrical connection between the (2-2)th touch line 1332 and the (2-3)th touch line 1333 by controlling the fourth switch 1344 to be opened. The touch sensor IC may recognize the position of user input (e.g. touch input or hovering input). When the recognized position is in the surrounding part 1300, the touch sensor IC may configure at least one of the switches 1341, 1342, 1343, and 1344 to be closed. When the recognized position is outside 1380 the surrounding part 1300, the touch sensor IC may configure the switches 1341, 1342, 1343, and 1344 to be opened.

FIG. 14 illustrates a display having a wiring structure for connecting touch electrodes around an opening to each other according to various embodiments. For the convenience of description, elements overlapping those in FIG. 6 will be described briefly, or a description thereof will be omitted. Referring to FIG. 14, in a surrounding part 1400 (e.g. the surrounding part 600 in FIG. 6), a (1-1)th touch line 1411, a (1-2)th touch line 1412, and a (1-3)th touch line 1413 may be arranged in the X-axis direction, and a (2-1)th touch line 1431, a (2-2)th touch line 1432, and a (2-3)th touch line 1433 may be arranged in the Y-axis direction while crossing the (1-1)th touch line 1411, the (1-2)th touch line 1412, and the (1-3)th touch line 1413. When the second opening 332 and the dead space 342 surrounding the same are formed such that the center of the second opening 332 is close to or is substantially aligned with the center of a touch electrode included in the (1-2)th touch line 1412, the touch electrode may be lost. Thus, in the (1-2)th touch line 1412, a first touch electrode 1412a and a second touch electrode 1412b are electrically disconnected from each other at the location of the lost touch electrode therebetween. The first touch electrode 1412a may be electrically connected to the second touch electrode 1412b via a connection wire 1461 formed in the dead space 342.

According to various embodiments, touch electrodes may be arranged so as not to be electrically disconnected from each other by an opening. According to one embodiment, when the pitch between the (2-1)th touch line 1431 and the (2-2)th touch line 1432, which are adjacent to each other, is wider than the width of the dead space 342 in the same direction, each of the (2-1)th touch line 1431 and the (2-2)th touch line 1432 may be disposed in the surrounding part 1400, with no part electrically interrupted by the second opening 332 and the dead space 342. According to one embodiment, when the width of touch electrodes included in the (2-1)th touch line 1431 is configured to become narrow from a first width 1441 to a second width 1442 and the width of touch electrodes included in the (2-2)th touch line 1432 is configured to become narrow from the first width 1441 to the second width 1442, the pitch between the (2-1)th touch line 1431 and the (2-2)th touch line 1432 may be configured to become wide from a first pitch 1451 to a second pitch 1452, and the second pitch 1452 may be wider than the width 1471 of the dead space 342.

FIG. 15 illustrates a display having a wiring structure for connecting touch electrodes around an opening to a touch sensor IC according to various embodiments. For the convenience of description, elements overlapping those in FIG. 6 will be described briefly, or a description thereof will be omitted. Referring to FIG. 15, in a surrounding part 1500 (e.g. the surrounding part 600 in FIG. 6), a (1-1)th touch line 1511, a (1-2)th touch line 1512, and a (1-3)th touch line 1513 may be arranged in the X-axis direction, and a (2-1)th touch line 1531, a (2-2)th touch line 1532, and a (2-3)th touch line 1533 may be arranged in the Y-axis direction while crossing the (1-1)th touch line 1511, the (1-2)th touch line 1512, and the (1-3)th touch line 1513. The second opening 332 and the dead space 342 surrounding the same may be formed at a point 1551 at which the (1-2)th touch line 1512 crosses the (2-1)th touch line 1531. Thus, in the (1-2)th touch line 1512 including a first touch electrode 1512a and a second touch electrode 1512b, a part of the first touch electrode 1512a and a part of the second touch electrode 1512b are lost due to the second opening 332 and the dead space 342. Therefore, the first touch electrode 1512a and the second touch electrode 1512b are electrically disconnected from each other. In the (2-1)th touch line 1531 including a third touch electrode 1531a and a fourth touch electrode 1531b, a part of the third touch electrode 1531a and a part of the fourth touch electrode 1531b may be lost due to the second opening 332 and the dead space 342, and thus the third touch electrode 1531a and the fourth touch electrode 1531b may be electrically disconnected from each other. The first touch electrode 1512a may be electrically connected to the second touch electrode 1512b via a connection wire 1561 formed in the dead space 342.

According to various embodiments, a wire for electrically connecting two parts of a touch line (e.g. the (2-1)th touch line 1531), cut and bisected by an opening (e.g. the second opening 332), to a touch sensor IC (e.g. the touch sensor IC 253 in FIG. 2) may be formed in a display (e.g. the display 310 in FIG. 3). According to one embodiment, a first wire 1571 and a second wire 1572 may be formed in a non-display region (e.g. the non-display region 312
