FIELD OF THE DISCLOSURE

The disclosure relates to a display technical field, and more particularly to a display panel and a mask for a manufacturing process of a display panel.

BACKGROUND

Liquid crystal displays are widely applied due to numerous advantages such as thin bodies, energy saving, radiation-free, etc. Most liquid crystal displays available on the market are backlight-type liquid crystal displays, and such liquid crystal display includes a liquid crystal panel and a backlight module. The working principle of the liquid crystal panel is placing liquid crystal molecules between two parallel glass substrates and applying a driving voltage on the two glass substrates to control rotation directions of the liquid crystal molecules, for refracting rays from the backlight module to generate images.

A thin film transistor-liquid crystal display (TFT-LCD) gradually occupies the dominant position in the display realm at present because of its properties such as low energy consumption, superior image quality and relatively high production yield, etc. Identically, the TFT-LCD includes a liquid crystal panel and a backlight module. The liquid crystal panel includes a color filter (CF) substrate, a thin film transistor (TFT) array substrate and a mask. The opposite internal sides of the substrates have transparent electrodes. A layer of liquid crystal (LC) molecules is interposed between the two substrates.

The conventional pixel design adopts a rectangle with sharp angles. The serration around the displayed word can be seen by eyes and the display effect is degraded. The poor images can hardly satisfy the developing requirement on displayed images of customers.

SUMMARY

A technical problem will be solved by the disclosure is to provide a display panel capable of improving image smoothness.

Furthermore, the disclosure further provides a display device.

Furthermore, the disclosure further provides a mask for a manufacturing process of a display panel.

The objective of the disclosure is achieved by following embodiments. A display panel includes scan lines and data lines.

The data lines are disposed intersecting with the scan lines to form a plurality of pixel regions; each of the pixel regions is disposed with a pixel structure correspondingly. The pixel structure includes a pixel. Edges of the pixel at least include an arc section.

Each pixel includes subpixels corresponding to different colors. The subpixels can include subpixels corresponding to colors such as white (W), yellow (Y) besides RGB. The colors are more diverse and the display effect is also better.

Each of the subpixels includes at least two unit pixels. A shape of the unit pixel is round. The at least two unit pixels and the round unit pixels specify structural properties of the subpixels. The amount of at least two is convenient for diversifying the arrangements. Round is a conventional shape in processing for reducing costs.

The adjacent two unit pixels are externally-tangent. The externally-tangent arrangement makes the unit pixels closed to better ensure the smoothness of images.

The subpixels include three unit pixels. An included angle between a line connecting a center of circle of the unit pixel on one end with a center of circle of the unit pixel in the middle and a line connecting a center of circle of the unit pixel on the other end with the center of the circle of the unit pixel in the middle is 120°. The specific arrangement of the unit pixels in the subpixels is clarified. The three unit pixels corresponding to the subpixels are arranged as a fold line with a certain angle. The three unit pixels and those in adjacent subpixels are externally-tangent to maximize the area of subpixels for improving image display.

The subpixel is the polygon with arc corners, elliptic or round. When the subpixel is the polygon with arc corners, the smooth arc can prevent the serration brought by sharp angles. The ellipse is simple in the structure and convenient for the process. The round is a conventional shape in processing for reducing costs.

The scan lines and the data lines match a contour curve of the pixel. The scan lines and the data lines match the contour curve of the pixel to ensure the proper operation of the pixel electrode after the pixels are arced, so that the display panel can show smooth images.
