130, and the data lines R1 to R4, G1 to G4, and B1 to B4 shown in FIG. 5, reference may be made to the relevant descriptions of the source driver 220, the display panel 130, and the data lines DL21_1 to DL21_s, DL22_1 to DL22_s shown in FIG. 2, or reference may be made to the relevant descriptions of the source driver 320, the display panel 130, and the data lines DL21_1 to DL21_s, DL22_1 to DL22_s shown in FIG. 3, and the same description applies by analogy, so details will not be repeated here.

The display device 100 further includes multiple demultiplexers (for example, demultiplexers DEMUX51, DEMUX52, DEMUX53, and DEMUX54 shown in FIG. 5), and the source driver 520 includes multiple source driver channels (for example, source driver channels 521, 522, 523, and 524 shown in FIG. 5). For the demultiplexer DEMUX51 to DEMUX54 and the source driver channels 521 to 524 shown in FIG. 5, reference may be made to the relevant descriptions of the demultiplexer DEMUX21 to DEMUX22 and the source driver channels 221 to 222 shown in FIG. 2, or reference may be made to the relevant descriptions of the demultiplexers DEMUX21 to DEMUX22 and the source driver channels 321 to 322 shown in FIG. 3, and the same description applies by analogy, so details will not be repeated here.

In the embodiment shown in FIG. 5, the common terminals of the demultiplexer DEMUX51 to DEMUX54 are directly or indirectly coupled to the output terminals of the source driver channels 521 to 524 respectively. The color attributes of at least two data lines connected to the same demultiplexer are the same color. For example, the selection terminals E1, E2, and E3 of the demultiplexer DEMUX51 are respectively coupled to the data lines R1, R3, and B1 (the first line, seventh line, and third line in the data line group, in which the color attributes of the data lines R1 and R3 are both red). The selection terminals E1, E2, and E3 of the demultiplexer DEMUX52 are respectively coupled to the data lines G1, G3, and B2 (the second line, eighth line, and sixth line in the data line group, in which the color attributes of the data lines G1 and G3 are both green). The selection terminals E1, E2, and E3 of the demultiplexer DEMUX53 are respectively coupled to the data lines G2, G4, and B3 (the fifth line, eleventh line, and ninth line in the data line group, in which the color attributes of the data lines G2 and G4 are both green). The selection terminals E1, E2, and E3 of the demultiplexer DEMUX54 are respectively coupled to the data lines R2, R4, and B4 (the fourth line, tenth line, and twelfth line in the data line group, in which the color attributes of the data lines R2 and R4 are both red).

FIG. 6 is a schematic diagram of a demultiplexing sequence of the demultiplexers DEMUX51 and DEMUX52 according to an embodiment of the disclosure. The horizontal axis of FIG. 6 represents time. The upper part of FIG. 6 shows the demultiplexing sequence of the demultiplexer DEMUX51, while the lower part of FIG. 6 shows the demultiplexing sequence of the demultiplexer DEMUX52. In the embodiment shown in FIG. 6, both demultiplexers DEMUX51 and DEMUX52 have the same demultiplexing sequence. FIG. 6 shows unit periods UP611, UP612, UP613, UP614, UP621, UP622, UP623, and UP624. It should be noted that the starting data line selected in one unit period can be varied according to actual applications. A unit period is equivalent to a horizontal line period (or scan line period). Multiple consecutive unit periods are defined as a cycle period, and different unit periods in the same cycle period have different demultiplexing sequence. For example, the demultiplexing sequence of the demultiplexer DEMUX51 in the unit period UP611 is the selection terminal E1, the selection terminal E2, the selection terminal E3, the demultiplexing sequence of the demultiplexer DEMUX51 in the unit period UP612 is the selection terminal E3, the selection terminal E1, the selection terminal E2, the demultiplexing sequence of the demultiplexer DEMUX51 in the unit period UP613 is the selection terminal E2, the selection terminal E1, the selection terminal E3, and the demultiplexing sequence of the demultiplexer DEMUX51 in the unit period UP614 is the selection terminal E3, the selection terminal E2, the selection terminal E1.

The same demultiplexer has the same demultiplexing sequence in different cycle periods in the same frame period. For example, in the embodiment shown in FIG. 6, four consecutive unit periods UP611 to UP614 are defined as a cycle period CP61, and four consecutive unit periods UP621 to UP624 are defined as a cycle period CP62. The following description will take the cycle period CP61 as an example. For the cycle period CP62, reference may be made to the relevant descriptions of the cycle period CP61, and the same description applies by analogy.

Please refer to FIG. 5 and FIG. 6. The demultiplexers DEMUX51 to DEMUX54 continuously select at least two different data lines with the same color attribute in each unit period. For example, in the unit period UP611, the demultiplexer DEMUX51 continuously selects the data lines R1 and R3 both with the color attributes as red, while the demultiplexer DEMUX52 continuously selects the data lines G1 and G3 both with the color attributes as green.

In the embodiment of FIG. 6, among the data lines coupled to the demultiplexer DEMUX51, only the data line B1 has a color attribute as blue, and among the data lines coupled to the demultiplexer DEMUX52, only the data line B2 has a color attribute as blue. A right boundary (first boundary) of the unit period UP611 is temporally adjacent to a left boundary (second boundary) of the unit period UP612. The demultiplexer DEMUX51 continuously selects the data line B1 with the color attribute as blue at the right boundary of the unit period UP611 and the left boundary of the unit period UP612, and the demultiplexer DEMUX52 continuously selects the data line B2 with the color attribute as blue at the right boundary of the unit period UP611 and the left boundary of the unit period UP612.

Please note that the above is just an example. The starting unit period selected in one cycle period can be varied according to actual applications. For example, in another embodiment, the cycle period CP61 may include unit periods UP612, UP613, UP614, and UP621 (the unit period UP611 belongs to a previous cycle period not shown), and the cycle period CP62 may include unit periods UP622, UP623, and UP624.

Based on the above, the common terminal of the demultiplexer DEMUX51 is coupled to the output terminal of the source driver channel 521, and the selection terminals E1, E2, and E3 of the demultiplexer DEMUX51 are coupled to the data lines R1, R3, and B1 respectively. Based on the switching operation of the demultiplexer DEMUX51, the multiple data lines R1, R3, and B1 of the display panel 130 can share the same source driver channel 521 of the source driver 520. Therefore, the total number of the source driver channels of the source driver 520 can be effectively reduced. In addition, the demultiplexer DEMUX51 continuously selects the multiple data lines R1 and R3 with the same color attribute (red) in the same unit period UP611, so the red sub-pixel of the data line R3 is more fully charged. The demultiplexer DEMUX51 continuously selects the data line B1 with the color attribute as blue at the boundary between the unit period UP611 and the unit period UP612, so the blue sub-pixel of the data line B1 is more fully charged in the unit period UP612. By the same token, based on the demultiplexing sequence of the demultiplexer DEMUX52, the green sub-pixel of the data line G3 is more fully charged, and the blue sub-pixel of the data line B2 is more fully charged in the unit period UP612. Therefore, the display device 100 can improve the uniformity of a single color image. Another advantage is that this arrangement can have the demultiplexer stay at the same data line as switching between two adjacent unit periods which improves color uniformity.

In some application examples, the same demultiplexer may have the same demultiplexing sequence in different frame periods. In some other application examples, the same demultiplexer may have different demultiplexing sequences in different frame periods. For example, the demultiplexing sequences of the demultiplexer DEMUX51 in the unit periods UP611, UP612, UP613, and UP614 in the first frame period may be a first demultiplexing sequence, a second demultiplexing sequence, a third demultiplexing sequence, and a fourth demultiplexing sequence respectively. In a second frame period after the first frame period, the demultiplexing sequences of the demultiplexer DEMUX51 in the unit periods UP611, UP612, UP613, and UP614 may be the second demultiplexing sequence, the third demultiplexing sequence, the fourth demultiplexing sequence, and the first demultiplexing sequence respectively. In a third frame period after the second frame period, the demultiplexing sequences of the demultiplexer DEMUX51 in the unit periods UP611, UP612, UP613, and UP614 may be the third demultiplexing sequence, the fourth demultiplexing sequence, the first demultiplexing sequence, and the second demultiplexing sequence respectively. In a fourth frame period after the third frame period, the demultiplexing sequences of the demultiplexer DEMUX51 in the unit periods UP611, UP612, UP613, and UP614 may be the fourth demultiplexing sequence, the first demultiplexing sequence, the second demultiplexing sequence, and the third demultiplexing sequence respectively.

The “first demultiplexing sequence”, “second demultiplexing sequence”, “third demultiplexing sequence”, and “fourth demultiplexing sequence” may be different demultiplexing sequences based on actual design. For example (but not limited thereto), the first demultiplexing sequence is “the selection terminal E1, the selection terminal E2, the selection terminal E3”, the second demultiplexing sequence is “the selection terminal E3, the selection terminal E1, the selection terminal E2”, the third demultiplexing sequence is “the selection terminal E2, the selection terminal E1, the selection terminal E3”, and the fourth demultiplexing sequence is “the selection terminal E3, the selection terminal E2, the selection terminal E1”.

The data lines R1, G1, B1, R2, G2, B2, R3, and G3 form a data line group of adjacent data lines. The color attributes of the data lines R1, R2, and R3 are all red. The color attributes of the data lines G1, G2, and G3 are all green. The color attributes of the data lines B1 and B2 are both blue. For the source driver 720, the display panel 130, and the data lines R1 to R3, G1 to G3, and B1 to B2 shown in FIG. 7, reference may be made to the relevant descriptions of the source driver 220, the display panel 130, and the data lines DL21_1 to DL21_s, DL22_1 to DL22_s shown in FIG. 2, or reference may be made to the relevant descriptions of the source driver 320, the display panel 130, and the data lines DL21_1 to DL21_s, DL22_1 to DL22_s shown in FIG. 3, and the same description applies by analogy, so details will not be repeated here.

The display device 100 further includes multiple demultiplexers (such as demultiplexers DEMUX71 and DEMUX72 shown in FIG. 7), and the source driver 720 includes multiple source driver channels (such as source driver channels 721 and 722 shown in FIG. 7). For the demultiplexer DEMUX71 to DEMUX72 and the source driver channels 721 to 722 shown in FIG. 7, reference may be made to the relevant descriptions of the demultiplexer DEMUX21 to DEMUX22 and the source driver channel 221 to 222 shown in FIG. 2, or reference may be made to the relevant descriptions of the demultiplexer DEMUX21 to DEMUX22 and the source driver channels 321 to 322 shown in FIG. 3, and the same description applies by analogy, so details will not be repeated here.

In the embodiment shown in FIG. 7, the common terminals of the demultiplexer DEMUX71 to DEMUX72 are directly or indirectly coupled to the output terminals of the source driver channels 721 to 722 respectively. The color attributes of at least two data lines connected to the same demultiplexer are the same color. For example, the selection terminals E1, E2, E3, and E4 of the demultiplexer DEMUX71 are respectively coupled to the data lines R1, B1, G2, and R3 (the first line, third line, fifth line, and seventh line in the data line group, in which the color attributes of the data lines R1 and R3 are both red). The selection terminals E1, E2, E3, and E4 of the demultiplexer DEMUX72 are respectively coupled to the data lines G1, R2, B2, and G3 (the second line, fourth line, sixth line, and eighth line in the data line group, in which the color attributes of the data lines G1 and G3 are both green).

FIG. 8 is a schematic diagram of the demultiplexing sequence of the demultiplexers DEMUX71 and DEMUX72 according to an embodiment of the disclosure. The horizontal axis of FIG. 8 represents time. The upper part of FIG. 8 shows the demultiplexing sequence of the demultiplexer DEMUX71, while the lower part of FIG. 8 shows the demultiplexing sequence of the demultiplexer DEMUX72. In the embodiment shown in FIG. 8, both demultiplexers DEMUX71 and DEMUX72 have the same demultiplexing sequence. FIG. 8 shows unit periods UP811, UP812, UP821, UP822, UP831, and UP832. The demultiplexing sequence of the demultiplexer DEMUX71 in the unit period UP811 is the selection terminal E2, the selection terminal E1, the selection terminal E4, the selection terminal E3, and the demultiplexing sequence of the demultiplexer DEMUX71 in the unit period UP812 is the selection terminal E3, the selection terminal E4, the selection terminal E1, the selection terminal E2.

The same demultiplexer has the same demultiplexing sequence in different cycle periods in the same frame period. For example, in the embodiment shown in FIG. 8, two consecutive unit periods UP811 to UP812 are defined as a cycle period CP81, two consecutive unit periods UP821 to UP822 are defined as a cycle period CP82, and two consecutive unit periods UP831 to UP832 are defined as cycle period CP83. The following description will take the cycle period CP81 as an example. For other cycle periods CP82 and CP83, reference may be made to the relevant descriptions of the cycle period CP81, and the same description applies by analogy.

Please refer to FIG. 7 and FIG. 8. The demultiplexers DEMUX71 to DEMUX72 continuously select at least two different data lines with the same color attribute in each unit period. For example, in the unit period UP811, the demultiplexer DEMUX71 continuously selects the data lines R1 and R3 both with the color attributes as red, while the demultiplexer DEMUX72 continuously selects the data lines G1 and G3 both with the color attributes as green.

In the embodiment of FIG. 8, among the data lines coupled to the demultiplexer DEMUX71, only the data line G2 has a color attribute as green, and among the data lines coupled to the demultiplexer DEMUX72, only the data line B2 has a color attribute as blue. The right boundary (first boundary) of the unit period UP811 is temporally adjacent to the left boundary (second boundary) of the unit period UP812. The demultiplexer DEMUX71 continuously selects the data line G2 with the color attribute as green at the right boundary of the unit period UP811 and the left boundary of the unit period UP812, and the demultiplexer DEMUX72 continuously selects the data line B2 with the color attribute as blue at the right boundary of the unit period UP811 and the left boundary of the unit period UP812. Among the data lines coupled to the demultiplexer DEMUX71, only the data line B1 has a color attribute as blue, and among the data line coupled to the demultiplexer DEMUX72, only the data line R2 has a color attribute as red. The right boundary (third boundary) of the unit period UP812 is temporally adjacent to the left boundary (fourth boundary) of the unit period UP821. The demultiplexer DEMUX71 continuously selects the data line B1 with the color attribute as blue at the right boundary of the unit period UP812 and the left boundary of the unit period UP821, and the demultiplexer DEMUX72 continuously selects the data line R2 with the color attribute as red at the right boundary of the unit period UP812 and the left boundary of the unit period UP821.

Please note that the above is just an example. The starting unit period selected in one cycle period can be varied according to actual applications. For example, in another embodiment, the cycle period CP81 may include unit periods UP812 and UP821 (the unit period UP811 belongs to a previous cycle period not shown), the cycle period CP82 may include unit periods UP822 and UP831, and the cycle period CP83 may include unit period UP832.

Based on the above, the common terminal of the demultiplexer DEMUX71 is coupled to the output terminal of the source driver channel 721, and the selection terminals E1, E2, E3, and E4 of the demultiplexer DEMUX71 are coupled to the data lines R1, B1, G2, and R3 respectively. Based on the switching operation of the demultiplexer DEMUX71, the multiple data lines R1, B1, G2, and R3 of the display panel 130 can share the same source driver channel 721 of the source driver 720. Therefore, the total number of the source driver channels of the source driver 720 can be effectively reduced. In addition, the demultiplexer DEMUX71 continuously selects the data lines R1 and R3 with the same color attribute (red) in the same unit period UP811, so the red sub-pixel of the data line R3 is more fully charged. The demultiplexer DEMUX71 continuously selects the data line G2 with the color attribute as green at the boundary between the unit period UP811 and the unit period UP812, so the green sub-pixel of the data line G2 is more fully charged in the unit period UP812. The demultiplexer DEMUX71 continuously selects the data line B1 with the color attribute as blue at the boundary between the unit period UP812 and the unit period UP821, so the blue sub-pixel of the data line B1 is more fully charged in the unit period UP821. By the same token, based on the demultiplexing sequence of the demultiplexer DEMUX72, the green sub-pixel of the data line G3 is more fully charged in the unit period UP811, the blue sub-pixel of the data line B2 is more fully charged in the unit period UP812, and the red sub-pixel of the data line R2 is more fully charged in the unit period UP821. Therefore, the display device 100 can improve the uniformity of a single color image. Another advantage is that this arrangement can have the demultiplexer stay at the same data line as switching between two adjacent unit periods which improves color uniformity.

In some application examples, the same demultiplexer has the same demultiplexing sequence in different frame periods. In some other application examples, the same demultiplexer may have different demultiplexing sequences in different frame periods. For example, the demultiplexing sequence of the demultiplexer DEMUX
