Description

一种显示面板 技术领域
本申请涉及显示技术领域，尤其涉及一种显示面板。
 背景技术
目前随着显示技术的迭代更新，用户除了对显示器分辨率的要求越来越高之外，还对显示屏幕的美观，视觉舒适度提出了越来越高的要求。因此，具有区别于传统矩形显示的各类显示面板应运而生，并用于手机和电视显示之中。对于圆角显示面板来说，其像素设计主要为矩形，在圆角区域直接用圆弧来进行遮光得到的显示区域明显会因为部分子像素过小的显示面积而导致色偏现象极其严重。为了解决圆角显示不均，现有技术的圆角显示面板，将显示区域边缘处的像素按边界的形状排列成阶梯状，从而形成了锯齿状边缘。这些排列在锯齿状边缘的像素与完全呈现黑暗的非显示区域之间形成了强烈的颜色对比，使得显示区域的锯齿状边缘被人眼识别到，导致异形显示面板出现锯齿效应与彩边效应，从而降低了异形显示面板的视觉效果，影响用户体验。
综上所述，现有的显示面板，在制备圆角显示面板过程中将显示区域边缘处的像素按边界的形状排列成阶梯状时，导致显示面板出现锯齿效应与彩边效应，从而降低了异形显示面板的视觉效果，影响用户体验。
