Description

一种液晶显示面板及其终端装置 技术领域
本发明涉及显示技术领域，具体涉及一种液晶显示面板及其终端装置。
 背景技术
液晶是一种介于固体和液体之间的特殊物质，它是一种有机化合物，常态下呈液态，但是它的分子排列却和固体晶体一样非常规则，因此取名液晶。液晶的另一个特殊性质在于，在不施加电场时，光线可以顺利透过；在给液晶施加一个电场的情况下，会改变它的分子排列，这时如果给它配合偏振光片，它就具有阻止光线通过的作用，如果再配合彩色滤光片，改变加给液晶电压大小，就能改变某一颜色透光量的多少，也可以形象地说改变液晶两端的电压就能改变它的透光度。
液晶显示器（英文全称：Liquid Crystal Display，简称LCD）的工作原理是将液晶置于两片导电玻璃之间，靠两个电极间电场的驱动，引起液晶分子扭曲向列的电场效应，以控制光源透射或遮蔽功能，在电源关开之间产生明暗变化，从而将影像显示出来。若加上彩色滤光片，则可显示彩色影像。在两片玻璃基板上装有配向膜，所以液晶会沿着沟槽配向，由于玻璃基板配向膜沟槽偏离90度，所以液晶分子成为扭转型，当玻璃基板没有加入电场时，光线透过偏光板跟着液晶做90度扭转，通过下方偏光板，液晶面板显示白色；当玻璃基板加入电场时，液晶分子产生配列变化，光线通过液晶分子空隙维持原方向，被下方偏光板遮蔽，光线被吸收无法透出，液晶面板显示黑色。液晶显示器便是根据此电压有无，使面板达到显示效果。
 技术问题
随着时代的发展进步，全面屏的市场发展迅猛，其中以刘海屏、水滴屏为代表，逐渐占据市场的主流，主要就是追求更高的屏占比。其开发思路是在屏幕上挖孔设计，放置前置摄像头。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，使用户方便持握，提升用户体验。具体的开发思路有两种，一种为通孔设计，另一种为盲孔设计。通孔主要是工艺复杂度、成本、玻璃强度等因素需要特别考虑，相反盲孔设计可以避开这些薄弱点。虽然盲孔比通孔占优势，但也有其薄弱的地方，主要是盲孔处玻璃透过率，此处对前置摄像头成像有直接影响，影响摄像头拍摄效果。因此需要寻求一种新型的液晶显示面板，既能达到盲孔的设计效果，又能提高盲孔处玻璃的透过率。
 技术解决方案
本发明的一个目的是提供一种液晶显示面板，其能够解决目前盲孔设计中光线透过率低的问题。
为了解决上述问题，本发明涉及的一个实施方式提供了一种液晶显示面板，包括依次设置的背光模组、下偏光片、TFT层、液晶层、彩色滤光片、上偏光片、光学胶、防护玻璃罩。其中所述光学胶局部向下凹陷形成第一盲孔，其中所述防护玻璃罩对应所述第一盲孔的位置处设置有一菲涅尔透镜。
进一步地，其中所述菲涅尔透镜的半径超出所述第一盲孔的半径尺寸的范围为0-5mm。
进一步地，其中所述第一盲孔向下凹陷穿透所述上偏光片直至所述彩色滤光片表面。
进一步地，其中所述下偏光片对应所述第一盲孔的位置处向下凹陷形成第二盲孔。
进一步地，其中所述第二盲孔向下凹陷穿透所述背光模组。
进一步地，其中所述菲涅尔透镜的制作方法包括CNC机械加工、玻璃注塑以及浇铸中的一种或多种。
进一步的，本发明的又一实施方式提供了一种终端装置，包括本体，所述本体上设有上述本发明涉及的所述液晶显示面板。
进一步地，其中所述本体中还设有一摄像头，所述摄像头的位置位于所述第一盲孔的正下方，所述摄像头的入光侧朝向所述下偏光片。
进一步地，其中所述摄像头设置于所述液晶显示面板的第二盲孔内。
进一步地，其中所述终端装置包括手机、平板、移动通讯设备中的一种或多种。
 有益效果
本发明涉及一种液晶显示面板及其终端装置。通过CNC机械加工、玻璃注塑以及浇铸等方式在所述防护玻璃罩对应于第一盲孔的位置处设置一菲涅尔透镜。光线经过菲涅尔透镜，把光线调整成平行光或聚光，在经过第一盲孔、彩色滤光片、液晶层、TFT层以及第二盲孔进入摄像头的入光口，提高了光线在防护玻璃罩处的透过率，避免对摄像头成像造成影响，提高摄像头的拍摄效果。
 附图说明
为了更清楚地说明本发明实施例中的技术方案，下面将对实施例描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本发明的一些实施例，对于本领域技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图。

 本发明的最佳实施方式
以下结合说明书附图详细说明本发明的优选实施例，以向本领域中的技术人员完整介绍本发明的技术内容，以举例证明本发明可以实施，使得本发明公开的技术内容更加清楚，使得本领域的技术人员更容易理解如何实施本发明。然而本发明可以通过许多不同形式的实施例来得以体现，本发明的保护范围并非仅限于文中提到的实施例，下文实施例的说明并非用来限制本发明的范围。
本发明所提到的方向用语，例如「上」、「下」、「前」、「后」、「左」、「右」、「内」、「外」、「侧面」等，仅是附图中的方向，本文所使用的方向用语是用来解释和说明本发明，而不是用来限定本发明的保护范围。
在附图中，结构相同的部件以相同数字标号表示，各处结构或功能相似的组件以相似数字标号表示。此外，为了便于理解和描述，附图所示的每一组件的尺寸和厚度是任意示出的，本发明并没有限定每个组件的尺寸和厚度。
当某些组件，被描述为“在”另一组件“上”时，所述组件可以直接置于所述另一组件上；也可以存在一中间组件，所述组件置于所述中间组件上，且所述中间组件置于另一组件上。当一个组件被描述为“安装至”或“连接至”另一组件时，二者可以理解为直接“安装”或“连接”，或者一个组件通过一中间组件“安装至”或“连接至”另一个组件。
如图1所示，本发明的一个实施方式提供了一终端装置，其包括本体。所述本体上设置有一摄像头11和液晶显示面板。
其中所述液晶显示面板包括依次设置的背光模组1、下偏光片2、TFT层3、液晶层4、彩色滤光片5、上偏光片6、光学胶7、防护玻璃罩8。
其中所述背光模组1主要由光源、导光板、光学用膜片、塑胶框等组成。由于液晶显示是被动发光元件，显示屏本身并不发光，因此需要由其下方的背光模组1照亮。
其中所述下偏光片2的基本结构包括：最中间的PVA（聚乙烯醇），两层TAC（三醋酸纤维素），PSA film（压敏胶），Release film(离型膜) 和Protective film（保护膜）。其中PVA膜是一种高分子聚合物，用各类具有二向色性的有机染料进行染色，同时在一定的湿度和温度条件下进行延伸，使其吸收二向色性染料形成偏振性能，在脱水、烘干后形成偏光片原膜；由于PVA膜具有亲水性，在湿热的环境中很快就会变形、收缩、松弛、衰退、且强度很低，质脆易破，不便于实用和加工，因此需要在膜两边都复合上一层强度高、透光率高而又耐湿热的TAC膜，由此形成了偏光片原板。偏光片的作用是使自然光变成线偏振光。
其中所述TFT（英文全称：thin film transistor，薄膜晶体管）的作用是用来主动控制每一个像素的器件，这样就相当于在每一个像素点上设计了一个场效应开关管，多个TFT构成TFT层3。
其中所述彩色滤光片5（英文全称：Color filter，简称CF）基本结构是由玻璃基板（Glass Substrate），黑色矩阵（Black Matrix），彩色层（Color Layer），保护层（Over Coat），ITO导电膜组成。彩色滤光片是一种表现颜色的光学滤光片，它可以精确选择欲通过的小范围波段光波，而反射掉其他不希望通过的波段。
其中所述下偏光片6的基本结构与下偏光片2的基本结构一致。为实现液晶片能够显示图像，需要上偏光片6和下偏光片2共同存在。
其中所述光学胶7是用于胶结透明液晶显示面板中的光学元件的特种胶粘剂。
其中所述光学胶7局部向下凹陷形成第一盲孔9，所述第一盲孔9向下凹陷穿透所述上偏光片6直至所述彩色滤光片5表面。所述下偏光片2对应于所述第一盲孔9的位置处向下凹陷形成第二盲孔10，所述第二盲孔10向下凹陷穿透所述背光模组1。
其中所述防护玻璃罩8是用来保护其他光学元件，防止其被灰尘、空气中的水分等侵蚀破坏。通过CNC机械加工、玻璃注塑以及浇铸等方式在所述防护玻璃罩8对应于所述第一盲孔的位置处设置有一菲涅尔透镜81。所述所述菲涅尔透镜81的半径大于所述第一盲孔9的半径。其中所述菲涅尔透镜81的外形尺寸稍大于所述第一盲孔9的外形尺寸，可以实现更好的聚光效果。具体的，其优选超出的半径尺寸范围在0-5mm。
其中所述摄像头位于所述第二盲孔10中，所述摄像头位于所述第一盲孔的正下方，所述摄像头11的入光侧朝向所述下偏光片2，外部光线经过防护玻璃罩8的菲涅尔透镜81、第一盲孔9、彩色滤光片5、液晶层4、TFT层3以及第二盲孔10进入摄像头的入光口，然后所述摄像头11将外界传入的光线进行接收形成图像。
如图2、图3所示，菲涅尔透镜81的俯视图包括直径从小到大的同心圆。所述菲涅尔透镜81的剖面图的上表面包括椭圆形的弧线811和锯齿形的凹槽812，所述菲涅尔透镜81的剖面图的下表面为光滑平整面。由此每个凹槽812都可以看做一个独立的小透镜，把光线调整成平行光或聚光。相对于普通的凸透镜，去掉直线传播的部分，只保留发生折射的曲面，便能省下大量材料同时达到相同的聚光效果，避免出现边角变暗、模糊的现象，从而提高在防护玻璃罩8处的光线透过率。
本发明所述终端的装置具体的包括手机、平板或者其他移动通讯设备。
以上对本发明所提供的液晶显示面板及其终端装置进行了详细介绍。应理解，本文所述的示例性实施方式应仅被认为是描述性的，用于帮助理解本发明的方法及其核心思想，而并不用于限制本发明。在每个示例性实施方式中对特征或方面的描述通常应被视作适用于其他示例性实施例中的类似特征或方面。尽管参考示例性实施例描述了本发明，但可建议所属领域的技术人员进行各种变化和更改。凡在本发明的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本发明的保护范围之内。
