Abstract

一种显示面板(100)及显示装置(40)，在显示面板(100)制备的时候，通过将第二支撑柱(301)与第一支撑柱(302)设置一高度差，这使得彩膜基板(20)在发生形变的时候，盲孔(120)内的第二支撑柱(301)由于并未支撑阵列基板(10)，进而增大盲孔(120)变形区域，缩小盲孔(120)变形的曲率半径，可以减低形变量，从而避免出现因盲孔(120)牛顿环效应产生的聚焦不良现象。

Description

显示面板及显示装置 技术领域
本发明涉及显示技术领域，尤其是涉及一种显示面板及显示装置。
 背景技术
目前业内的显示面板内摄像开孔技术，分为通孔及盲孔，通孔指玻璃基板、彩膜基板及阵列基板在镀膜时面内预留出一个圆孔空间，在切割时，对该圆孔进行研磨处理，以实现（Liquid Crystal Display，LCD）液晶显示器产品面内开孔设计。同样，盲孔也是在玻璃基板、彩膜基板及阵列基板镀膜时预留一个圆孔空间，然后在圆孔位置的膜层进行挖孔处理，不伤及玻璃基板，彩膜基板与阵列基板合板时，对该圆孔滴加液晶，在玻璃基板上形成一个圆形透光区，以实现LCD 产品面内开盲孔设计。
 技术问题
在液晶生产制作过程中，需要保证盲孔的透光率。因需要在盲孔区域挖空部分膜层，导致盲孔区液晶层高度与正常显示区域液晶层高度存在差异，但整个LCD 面板滴加液晶量一致，从而彩膜基板与阵列基板在真空组立的时候，盲孔区域的玻璃基板受真空影响会向内凹陷，以致盲孔区域彩膜基板与阵列基板形成一个凹透镜效果。并且在彩膜基板侧的玻璃与盖板玻璃贴合时，盲孔区域与显示区光刻胶胶厚一致，但光刻胶填充高度存在差异，真空贴合时，会加重凹透镜现象。导致孔下摄像头无法正常聚焦，影响摄像头拍照效果。
 技术解决方案
本发明的目的是提供一种显示面板及显示装置，在显示面板制备的时候，通过将第二支撑柱与第一支撑柱设置一高度差，这使得彩膜基板在真空组立的时发生形变，盲孔内的第二支撑柱由于并未支撑到阵列基板的一端，进而增大盲孔变形区域，来缩小盲孔变形的曲率半径，可以减低形变量，从而避免出现因盲孔牛顿环效应产生的聚焦不良现象。
为解决上述问题，本发明提供一种显示面板，包括:阵列基板，具有盲孔区以及显示区，所述盲孔区具有内径区以及外径区，所述外径区包围所述内径区；液晶层，设于所述阵列基板上，具有多个第一支撑柱以及多个第二支撑柱，所述第一支撑柱的高度大于所述第二支撑柱的高度；彩膜基板，设于所述液晶层远离所述阵列基板的一侧；其中，所述第一支撑柱设于所述显示区，所述第一支撑柱的一端连接所述阵列基板，其另一端连接所述彩膜基板；所述第二支撑柱设于所述显示区以及所述外径区，所述第二支撑柱一端连接所述彩膜基板，其另一端与所述阵列基板具有间隙。
进一步地，所述第一支撑柱的材料为有机光阻；和/或所述第二支撑柱的材料为有机光阻。
进一步地，所述第一支撑柱与所述第二支撑柱的差值为0.35~0.45um。
进一步地，在所述显示区，所述第二支撑柱与所述第一支撑柱交错分布。
进一步地，所述阵列基板包括：第一玻璃基板；缓冲层，设于所述第一玻璃基板上；薄膜晶体管层，设于所述缓冲层上，具有一对应所述盲孔区的第一组合孔，所述第一组合孔贯穿所述薄膜晶体管层直至所述缓冲层表面；第一配向膜，设于所述薄膜晶体层上以及所述第一组合孔中。
进一步地，所述第一组合孔包括第一通孔以及第二通孔，所述第一通孔的半径小于所述第二通孔的半径，所述第二通孔设于所述第一通孔的上方，且且所述第二通孔围绕所述第一通孔。
进一步地，所述彩膜基板包括：第二玻璃基板；黑色矩阵层，设于所述第二玻璃基板靠近所述阵列基板的一侧；透明电极层，设于所述黑色矩阵层上；RGB色阻，设于所述黑色矩阵层以及所述透明电极层中以及具有一对应所述盲孔区的第二组合孔，所述第二组合孔贯穿所述透明电极层以及所述黑色矩阵层直至所述第二玻璃基板表面；第二配向膜，设于所述透明电极层上以及所述第二组合孔中。
进一步地，所述第二组合孔包括第三通孔以及第四通孔；所述第三通孔的半径小于所述第四通孔的半径，所述第三通孔设于所述第四通孔的上。

 有益效果
本发明的有益效果是：本发明提供一种显示面板及显示装置，通过在外径区以及靠近外径区的显示区均设有第二支撑柱。在制备显示面板的时候，通过将第二支撑柱与第一支撑柱设置一高度差，这使得彩膜基板在真空组立发生形变时，盲孔区内的第二支撑柱由于并未支撑到阵列基板，进而增大实际盲孔的变形区域，以缩小实际盲孔变形的曲率半径，可以减低形变量，从而因盲孔牛顿环效应产生的聚焦不良现象，提高显示装置的拍摄质量。
