Embodiment Construction

[0044] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0045] After repeated studies, the inventors of the present invention found that the reasons for the step effect at the edge of the display area of ​​the existing display panel are as follows:

[0046] In the display panel in the prior art, the edges of the pixel units are mostly straight lines, such as figure 1 As shown, the edges of the pixel units 102' in each row are straight sides, and for a display panel with curved edges, there must be gaps between the pixel units whose edges are straight lines and the curved edges of the display panel without pixel units. The blank area 101 ′, which results in that when the display panel is displaying, the blank area 10...

Abstract

The invention provides a display substrate, at least one part of an edge of the display substrate is arc-shaped, the display substrate comprises a main display region, multiple rows of main pixel units are arranged in the main display region, each row of the main pixel unit comprises a plurality of main pixel units; at least one edge pixel unit is arranged at a space part between a row edge of themain pixel unit, corresponding to the arc-shaped edge of the display panel, and the arc-shaped edge; and shape of the main pixel units is different from the shape of the edge pixel unit. The invention also provides a mask for manufacturing the display substrate, a method for manufacturing the display substrate with the mask, and a display panel comprising the display substrate. The edge of the display substrate is provided with the edge pixel unit, thus, lightened area of the edge of the display region can be increased, a staircase effect of the edge of the display region of the display panelcan be improved, and display effect can be promoted.

Description

technical field [0001] The present invention relates to the field of display technology, in particular, to a display substrate, a mask for manufacturing the display substrate, a method for manufacturing the display substrate by using the mask, and a display panel including the display substrate . Background technique [0002] When the existing display panel with a circular or rounded display area is displayed, the display brightness is low at the edge of the display area of ​​the display panel, and the display brightness is high at the middle part of the display area, and obvious steps or jagged edges appear at the edge of the display area. Shaped burrs, known as the ladder effect in the industry, seriously affect the display effect. [0003] In the prior art, brightness correction is performed by changing the size of the backplane thin film transistor (TFT) to change its parasitic capacitance to solve the above problems. However, when changing the size of the backplane th...
