Description

一种液晶显示面板 技术领域
本发明涉及显示面板技术领域，特别涉及一种液晶显示面板。
 背景技术
最近两年市场上全面屏市场发展迅猛，其中以刘海屏、水滴屏为代表，逐渐占据市场的主流，主要特点是追求更高的屏占比。目前市场上有出现更高的屏占比的声音，虽然还没有真正量产品上市，但各家已经在开发。其开发思路是在屏幕上过孔设计，放置前置摄像头，将摄像机模组隐藏在面板中，面内过孔技术应运而生。其将有效显示区域做大，提高显示屏的屏占比；另外，由于可以减小非显示区域的大小，从而有效减小显示屏总尺寸，使用户方便尺握，提升用户体验。
对于有背光模组的液晶显示面板，如图1所示，图1为液晶显示面板过孔处的剖视示意图，图中从下往上依次是反射片11、导光板12、扩散片13、下增光层14、上增光层15、下偏光片2、TFT层3、彩膜基板4、上偏光片5、黑色矩阵6，在过孔处的下方位置放置摄像模组9。其中液晶显示面板还包括显示区和过孔区8，过孔区8包括可视孔区81、边界区82、背光孔区83。
由于过孔导致孔附近边缘漏光风险增加，传统胶铁一体防止漏光的方法使得过孔处的整体黑色矩阵即边界区很宽，该做法不仅工序繁琐也会导致机台、原料等成本增加。
同时，在正常显示画面时，边界区会是一圈黑色非显示区域，造成显示屏的外观不美观。
因此，确有必要来开发一种新型的液晶显示面板，以克服现有技术的缺陷。
“背景技术”段落只是用来帮助了解本发明内容，因此在“背景技术”段落所揭露的内容可能包含一些没有构成本领域技术人员所知道的现有技术，在“背景技术”段落所揭露的内容，不代表该内容或者本发明一个或多个实施例所要解决的问题，也不代表在本发明申请前已被本领域技术人员所知晓或认知。

 有益效果
相对于现有技术，本发明的有益效果在于：本发明提供一种液晶显示面板，在其过孔处的背光模组各膜片之间增加黑色双面胶作为支撑，反射片在过孔处虚切一个圆，沿着虚切线向上折弯反射片，通过黑色遮光胶向上折弯形成黑色挡墙以遮挡导光板，这样的设置方式既可以避免漏光又简单易行，大大降低了成本，节约了产出时间，并且这样的设置方式使得整体黑色矩阵很窄，使显示屏的外观更美观。

实施例1
请参阅图2，为实现上述目的，本发明提供一种液晶显示面板，其定义有过孔区8和显示区，包括依次设置的背光膜层、下偏光片2、TFT层3、彩膜基板4、上偏光片5，下偏光片2设置于背光膜层上，TFT层3设置于下偏光片2上，彩膜基板4设置于TFT层3上，上偏光片5设置于彩膜基板4上。
背光膜层包括依次设置的反射片、导光板12、扩散片13、下增光层14、上增光层15，导光板12设置于反射片上，扩散片13设置于导光板12上，下增光层14设置于扩散片13上，上增光层15设置于下增光层14上。
反射片包括第一反射片111和向上折弯的第二反射片112。第一反射片111在过孔区8中的长度L1和第二反射片112的长度L2之和小于过孔区8的半径。第二反射片112的长度等于背光膜层的厚度，第二反射片112通过向上折弯以达到固定整个背光膜层的作用。
反射片下表面贴附有单面黑色遮光胶，黑色遮光胶包括第一黑色遮光胶61和向上折弯的第二黑色遮光胶62。
在过孔区8内，在导光板12和扩散片13之间设置第一黑色双面胶71，扩散片13和下增光层14之间设置有第二黑色双面胶72，下增光层14和上增光层15之间设置有第三黑色双面胶73，上增光层15和下偏光片2之间设置有第四黑色双面胶74。其中，过孔区是通过激光镭射挖孔制作而成的。
其中，在背光模组的各膜层之间设置黑色双面胶不仅能够起到遮光的作用，还能起到支撑各膜层的作用。
第一黑色遮光胶61的长度L3大于第二反射片112的厚度，小于第二反射片112的厚度和第一黑色双面胶71的长度L3之和。这样的设置方式能够防止通过第二反射片112漏光。
第二黑色遮光胶62的长度L4等于第一反射片111的厚度和导光板12的厚度之和，第二黑色遮光胶62通过向上折弯形成黑色挡墙，防止第一反射片112和导光板12漏光。
过孔区8包括可视孔区81、边界区82、背光孔区83。本发明的设置方式使得边界区相对于现有技术更窄，使显示屏的外观更美观。
实施例2
本发明的又一实施方式是提供一种终端装置，其包括本体，本体上设置有本实施1提供的液晶显示面板。本体上还设置有摄像机模组，其设置在液晶显示面板过孔区的对应下方位置处。
本发明的有益效果在于：本发明提供一种液晶显示面板，在其过孔处的背光模组各膜片之间增加黑色双面胶作为支撑，反射片在过孔处虚切一个圆，沿着虚切线向上折弯反射片，通过黑色遮光胶向上折弯形成黑色挡墙以遮挡导光板，这样的设置方式既可以避免漏光又简单易行，大大降低了成本，节约了产出时间，并且这样的设置方式使得整体黑色矩阵很窄，使显示屏的外观更美观。
以上所述仅是本发明的优选实施方式，应当指出，对于本技术领域的普通技术人员，在不脱离本发明原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也应视为本发明的保护范围。
