Description

液晶显示面板及其应用的液晶显示装置 技术领域
本申请涉及一种无边框设计方法，特别是涉及一种液晶显示面板及其应用的液晶显示装置。
背景技术
TFT-LCD是薄膜晶体管液晶显示器的简称。TFT-LCD为背光型液晶显示器，其是由液晶显示面板及背光模块(Backlight Module)所组成，液晶显示面板包括：第一基板-彩膜基板(CF，Color Filter)、第二基板-薄膜晶体管基板(TFT，Thin Film Transistor)、夹于彩膜基板与薄膜晶体管基板之间的液晶(LC，Liquid Crystal)。而低温多晶硅(LTPS，Low Temperature Poly-silicon)是新一代薄膜晶体管液晶显示器(TFT-LCD)的制造流程，与传统非晶硅显示器最大差异在于LTPS反应速度较快，且有高亮度、高分辨率与低耗电量等优点。TFT-LCD分为多晶硅与非晶硅两种技术，目前主流TFT-LCD以非晶硅(a-Si)为主，相关技术较为成熟。由于LCD自身不能发光，因而需要背光模块。背光模块可包括诸如发光二极管、荧光灯等等的光源、导光板、棱镜片、扩散片、保护片等等。
TFT-LCD为了突显出显示画面的一体感，开始朝向无边框设计，而当边框取消之后，边缘的侧漏光问题就必须被克服，否则会出现外围漏光的现象，且当四边无边框的产品将面板阵列侧朝上显示时，周边的金属反光会造成视觉感官不佳，影响面板的品质。
发明内容
为了解决上述技术问题，本申请的目的在于，提供一种无边框设计方法，特别是涉及一种无边框设计的液晶显示面板，不仅可以吸收薄膜晶体管玻璃基板周边金属光线反射，并且降低因金属光线反射所造成视觉感官不佳的问题。
本申请的目的及解决其技术问题是采用以下技术方案来实现的。依据本申请提出的一种液晶显示面板，包括：一第一基板，具有一外表面；一第一偏光片，设置于所述第一基板的外表面；一第二基板，与所述第一基板相对设置，并具有一外表面；一第二偏光片，设置于所述第二基板的外表面，所述第二偏光片具有一外表面；一液晶层，设置于所述第一基板与所述第二基板之间；以及一遮光单元，设置于所述第二基板的外表面周缘或所述第二偏光片的外表面周缘。
本申请的目的及解决其技术问题还可采用以下技术措施进一步实现。

为更进一步阐述本申请为达成预定发明目的所采取的技术手段及功效，以下结合附图及较佳实施例，对依据本申请提出的一种液晶显示面板及其应用的液晶显示装置，其具体实施方式、结构、特征及其功效，详细说明如后。
液晶显示器(LCD，Liquid Crystal Display)通过施加一电场于两片玻璃基板之间的液晶，以显示数字或影像。其中所述液晶由介于液体与固体之间的物质所组成。由于液晶显示器无法自行发光，因此需要一背光模块来提供光线。画面则通过控制液晶显示面板的光线传送来形成。其中液晶均匀地设置于液晶显示面板中。
传统液晶显示器的背光模块(如图1所示)包括一光源20、一导光板102、一反射片103、一扩散片104、一棱镜片105及一保护片106。首先，光源20用以射出光线至液晶显示器中。目前已有多种不同的光源可应用于液晶显示器中。导光板102设置于液晶显示面板107之下，并邻近于光源20一侧。导光板102用以将光源20所产生的点状光线转换为面状光线，并将此面状光线投射于液晶显示面板107。
反射片103则设置于导光板102之下。反射片103用以将光源20所射出光线反射至反射片103之前的液晶显示面板107。扩散片104设置于导光板102之上，用以均匀化穿越导光板102的光线。当光线穿越扩散片104时，光线被扩散于水平与垂直方向。此时光线亮度将快速降低。就这一点而言，棱镜片105用以折射并集中光线，以藉此提高亮度。一般两个棱镜片105以相互垂直的方式排列。
保护片106设置于棱镜片105之上。在使用两个相互垂直排列棱镜片105的情况下，保护片106可以避免棱镜片105的刮伤，并避免水波纹现象(Moire Effect)的发生。传统液晶显示器的背光模块包括上述组件。
一般而言，当棱镜片105正常地装设时，数个单元棱柱将以规律的方向排列于一透明材料膜上。棱镜片105用以折射穿越导光板102并被扩散板104扩散的光线。一般而言，若光线传递与折射的宽度较小，则在传递与折射的区域内的光线将呈现的较亮。相反地，若光线传递与折射的宽度较大，则在传递与折射的区域内的光线将呈现的较暗。
近年来，液晶显示器朝向大尺寸面板发展。因此，如何维持背光模块所射出光线的密度在一预定水平之上，以及当液晶显示器为了突显出显示画面的一体感，开始朝向无边框设计，而当边框取消之后，边缘的侧漏光问题就必须被克服，否则会出现外围漏光的现象，且当四边无边框的产品会将面板阵列侧朝上显示时，周边的金属会反光造成视觉感官不佳影响面板的品质，所以如何均匀化所看到的光线又能解决边缘的侧漏光问题将是大尺寸面板的一个重要参考因素。
本申请的液晶显示设备可包括背光模块及液晶显示面板。液晶显示面板可包括薄膜晶体管(TFT，Thin Film Transistor)基板、彩色滤光片(CF，Color Filter)基板与形成于两基板之间的液晶层(LC Layer，Liquid Crystal Layer)。
在一实施例中，本申请的液晶显示面板可为曲面型显示面板，且本申请的液晶显示设备亦可为 曲面型显示装置。
