Description

一种轻薄型液晶显示装置及其背光模组与制作方法 技术领域
本发明涉及液晶显示技术领域，尤其涉及一种轻薄型液晶显示装置及其背光模组与制作方法。
背景技术
随着消费者需求的日益提升，显示装置中各模组的轻薄化越来越受到人们的关注与重视。通常，显示装置包括显示面板和背光模组，背光模组能够发出光线而作为显示面板的背光源。目前的背光模组按照光源与导光板的位置关系主要分为两种，直下式和侧入式，其中，直下式背光由于其结构限制，在厚度上不具备优势；而相对地，侧入式背光由于玻璃导光板的引入，模组厚度已突破4mm，大尺寸下极具视觉冲击力，但其重量很大，因此，市面上的显示装置虽然可以做到很薄，但其重量仍然是其一大缺陷。
发明内容
鉴于现有技术存在的不足，本发明提供了一种重量轻的轻薄型液晶显示装置及其背光模组与制作方法。
为了实现上述的目的，本发明采用了如下的技术方案：
一种轻薄型液晶显示装置，包括下基板、设于所述下基板上方的上基板以及自下而上依次设于所述下基板和所述上基板之间的下偏光片、薄膜晶体管阵列、液晶层、彩色滤光片，所述下基板旁还设置有侧入式光源，所述下基板的底面还设置有反射层。
作为其中一种实施方式，所述的轻薄型液晶显示装置还包括折射率小于所述下基板的折射层，所述折射层设于所述下基板和所述下偏光片之间。
作为其中一种实施方式，所述下基板为玻璃。
作为其中一种实施方式，所述折射层蒸镀形成在所述下基板表面。
作为其中一种实施方式，所述反射层为所述下基板上远离所述折射层的一 面形成的反射涂层。
或者，所述反射层为贴合于所述下基板底面的反射片。
作为其中一种实施方式，所述下基板的底面还阵列形成有散射网点。
本发明的另一目的在于提供一种所述的轻薄型液晶显示装置的背光模组，包括所述侧入式光源、所述下基板、所述折射层和所述反射层。
本发明的又一目的在于提供一种所述的轻薄型液晶显示装置的制作方法，所述折射层蒸镀形成在所述下基板表面。
作为其中一种实施方式，所述的轻薄型液晶显示装置的制作方法包括：在衬底上制作出薄膜晶体管阵列后剥离衬底，并在薄膜晶体管阵列底面贴附下偏光片。
本发明利用显示面板的下基板传导背光光线，将背光模组与显示面板有机地组合在一起，无需专门提供导光板，很大程度上降低了液晶显示装置的厚度、重量以及成本，同时又能保证显示装置的正常显示。
附图说明
图1为本发明实施例的液晶显示装置的结构示意图。
图2位本发明实施例的背光模组的结构示意图。
具体实施方式
为了使本发明的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本发明进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
参阅图1，本发明的轻薄型液晶显示装置包括下基板10、设于下基板10上方的上基板20以及自下而上依次设于下基板10和上基板20之间的下偏光片30、薄膜晶体管阵列40、液晶层50、彩色滤光片60，上基板20上还具有上偏光片70，下基板10旁还设置有侧入式光源1，在下基板10的底面还设置有反射层。
下基板10最好是采用玻璃，侧入式光源1一般选用LED灯条作为光源，侧入式光源1发出的光自下基板10的入光侧进入下基板10内部，经下基板10底部的反射层反射后自下基板10顶部的出光面射出。而下偏光片30位于液晶层50的下方，进入液晶层50的光线首先会经过下偏光片30的偏转作用形成特定 的线性偏振光，使液晶得以正常工作。
这里，显示装置内还具有低折射率的折射层11，该折射层11的折射率小于下基板10，设置在下基板10和下偏光片30之间，且完全覆盖下基板10，以实现光线在下基板10内的全反射。该折射层11通过蒸镀的方式形成在下基板10表面以与下基板10一体形成，同时，以此形成的折射层11可以轻易做成很薄的薄膜，降低制作难度，减薄显示装置的整体厚度，该折射层11最好是采用二氧化硅、氧化钙等材料制作。
反射层可以是贴合于下基板10底面的反射片80，采用低折射率的光学胶S粘贴在下基板10底部，以实现下基板10内光线的充分利用。作为其中一种较佳的实施方式，反射层是在下基板10上远离折射层11的一面涂覆或蒸镀形成的反射涂层，此种制作方式可以保证反射层的制作更简单、更薄，显示装置中各结构的集成度也更高。
另外，在下基板10的底面还阵列形成有散射网点100，这些散射网点100形成在下基板10内，可以破坏下基板10内的全反射，使更多的光自其上表面的出光面射出，照射或反射至散射网点100的光线可以被更加均匀地射出，提高显示装置的整体光线均匀性。散射网点的材料可以是油墨、钛系化合物或硅系化合物等，其表面为球形面或椭球形面。
通过这样的设置，显示面板的下基板可以作为传导背光光线的介质，充当传统显示装置中导光板的作用，将背光模组与显示面板有机地组合在一起，无需专门提供导光板，很大程度上降低了液晶显示装置的厚度、重量以及成本，同时又能保证显示装置的正常显示。
液晶显示装置工作时，侧入式光源1发出的光线首先自入光侧进入下基板10，光线在透明的下基板10内传播，其中一部分光线射向下基板10底部的反射片80，经反射片80反射后的光线射向下基板10顶部的出光面；一部分光线经反射片80上方的散射网点100反射后进行发散，起到匀光作用。而射向自出光面的光线中，出射角过大的部分光线由于折射层11的全反射作用反射回下基板10进行二次处理，避免了光线泄露或不集中，提高了光线利用率，同时还能起到一定程度的二次匀光效果，导致最终自折射层11射出的光线大多垂直于出光面，再经过下偏光片30的偏光处理形成适合液晶层50的偏振光，经过彩色滤光片60滤光，上偏光片70再次偏振处理后射出，最后形成彩色显示画面。
如图2所示，在上述轻薄型液晶显示装置中，背光模组主要由侧入式光源1、 下基板10、折射层11和反射层组成。这里，下基板10既是显示面板的一部分，也是背光模组的一部分，省去了厚重的导光板，导光板可以选用硬度较高的下基板替代，兼具导光和成型作用。
本发明的轻薄型液晶显示装置的制作方法与传统的液晶显示装置制作方法大致相同，主要区别在于：(1)折射层11是通过蒸镀工艺形成在下基板10表面，优选是通过斜角蒸镀形成；(2)散射网点100阵列形成在下基板10内；(3)薄膜晶体管阵列40的制作是在衬底上制作出薄膜晶体管阵列40后剥离衬底，然后在薄膜晶体管阵列40底面贴附下偏光片30。其中，该衬底优选是上述的下基板10，下基板10剥离后进行处理，集成折射层11、散射网点100与反射层以充当导光板，最后将下基板10组装到下偏光片30下即可。此种制作方式工艺简单且结构紧凑，将下偏光片30、薄膜晶体管阵列40、折射层11集成在液晶层50与下基板10之间，降低了显示装置的制作成本、整体厚度和重量。
以上所述仅是本申请的具体实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本申请原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也应视为本申请的保护范围。
