Description

液晶显示面板及液晶显示器
【技术领域】
本发明涉及显示技术领域，特别是涉及一种液晶显示面板及液晶显示器。
【背景技术】
LCD（Liquid Crystal Display）液晶显示器的背光模组的入光方式的不同，可以分为侧入式及直下式两类。
液晶显示面板是LCD液晶显示器的重要组成部分，其采用R（红）、G（绿）、B（蓝）三原色混色原理，在现有的技术中，为了保证LCD液晶显示器的整体观看效果，通常要求液晶显示面板的色差小于一个值，以使得用户的主观感觉上不会察觉到偏色的问题。而现有的液晶显示器的色偏问题通常是由背光模组引起的，例如对于侧入光式背光模组而言，光在导光板内进行光传播，以通过导光板内全反射的特性来实现混光均匀，因此，导光板是引起液晶显示器的色偏的主要原因。其原因是：导光板在可见光波段的光吸收不一致，通常是对于蓝光的吸收较为强烈，因此在光的传播方向上，蓝光吸收不断增加，导致光在导光板的传播方向上的色度发生变化，从而使得液晶显示面板内出现严重色差，即目前的液晶显示面板，在光传播方向上，容易出现近光侧偏蓝，远光侧偏黄的现象，无法满足规格要求。
【发明内容】
有鉴于此，本发明提供一种液晶显示面板及液晶显示器，可以提高液晶显示面板的蓝光穿透率，弥补背光模组中蓝光被吸收造成的色偏影响，降低LCD液晶显示面板的色差。

本发明的第三方面提供一种液晶显示器，包括液晶显示面板和侧入式背光模组，侧入式背光模组包括侧入式背光源，液晶显示面板包括多个呈阵列式排列的像素单元，每个像素单元包括依序排列的红色子像素、绿色子像素及蓝色子像素，每一像素单元的面积相等，且在远离侧入式背光源的方向上，蓝色子像素的透光率逐渐增大。
其中，在远离侧入式背光源的方向上，蓝色子像素的面积逐渐增大。

【具体实施方式】
为了使本发明所要解决的技术问题、技术方案及有益效果更加清楚、明白，以下结合附图和实施例，对本发明进行进一步详细说明。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。
请参看图1，图1是本发明一实施例的液晶显示器的俯视结构示意图。如图1所示，本实施例的液晶显示器100包括液晶显示面板200及侧入式背光源303，侧入式背光源303在液晶显示面板200的侧面，为液晶显示面板200提供光源，图1所示为侧入式背光源303与液晶显示面板200的俯视图。其中，液晶显示面板200包括多个呈阵列式排列的像素单元201，每个像素单元201的面积相等，且每个像素单元201包括依序排列的红色子像素R、绿色子像素G及蓝色子像素B，在各个像素单元201中，红色子像素R、绿色子像素G及蓝色子像素B以相同的次序沿水平方向排列。在远离侧入式背光源303的方向（即在光的传播方向）上，蓝色子像素B的透光率逐渐增大。如图1中所示的，在光的传播方向上，液晶显示面板200中的每个像素单元201的面积保持相等，蓝色子像素B的面积逐渐增大，并且在同一个像素单元201中，红色子像素R与绿色子像素G的面积保持相等，即随着蓝色子像素B的面积逐渐增大，红色子像素R及绿色子像素G所占像素单元201的面积比例相应的逐渐减小。
请进一步参看图2，图2是图1中的液晶显示器的剖面结构示意图。如图2所示，侧入式背光源303设置于导光板304的一侧，像素单元201包括依序排列的红色子像素R、绿色子像素G及蓝色子像素B，每个像素单元201的面积相等，红色子像素R、绿色子像素G及蓝色子像素B以相同的次序沿水平方向排列，在沿光的传播方向上，蓝色子像素B的面积逐渐增大。
因此，本实施例的液晶显示面板200，通过在光的传播方向上，逐渐增大蓝色子像素B的面积，相应的减小红色子像素R及绿色子像素G的面积，从而提高了蓝色子像素B的透光率，弥补背光模组300中蓝光被吸收所造成的液晶显示面板200出现的近光侧偏黄，远光侧偏黄的现象，降低液晶显示面板200的色差。
请进一步参看图3，图3是本发明另一实施例的液晶显示器的结构示意图。如图3所示，液晶显示器100包括侧入式背光源303、导光板304及彩色滤光片202，侧入式背光源303设置于导光板304的一侧，彩色滤光片202包括红色色阻210、绿色色阻220及蓝色色阻230，在光的传播方向上，保持每个像素单元（图2中未示像素单元）的面积相等，且同时保持蓝色子像素B的面积不变，而蓝色子像素B所对应的蓝色色阻230逐渐变薄。因此，本实施例通过在光的传播方向上逐渐减薄蓝色子像素B所对应的蓝色色阻230，从而可以提高蓝色子像素B的透光率，弥补背光模组300中蓝光被吸收所造成的液晶显示面板200出现的近光侧偏黄，远光侧偏黄的现象，降低液晶显示面板200的色差。
请参看图4，图4是图1中的侧入式背光模组的结构示意图。如图4所示，侧入式背光模组300包括：
铝挤301，其包括至少一部分铝挤竖板302；
侧入式背光源303，设置在铝挤竖板302的内侧壁上，侧入式背光源303包括但不限于为LED（发光二极管）；
导光板304，设有入光面305及出光面306，其中，导光板304的入光面305正对侧入式背光源303，导光板304背向出光面306的表面上设置有多个网点307，导光板304上的网点307通常是采用激光打点的方式在导光板304的一侧表面上形成凹点作为网点307。
进一步的，在导光板304的出光面306上还设置有多个TIR（全内反射）透镜308，以使从导光板304的出光面306输出的光线透过TIR透镜308进行全内反射，提高光的利用率。
此外，在导光板304的下方还设置有反射膜314，反射膜314设置于导光板304形成有网点307的一侧表面。在本实施例中，侧入式背光源303发出的光线在导光板304中的传播原理是：侧入式背光源303的LED灯发出的光线从导光板304的入光面305射入，通过反射膜314反射到TIR透镜308上，TIR透镜308进一步对光线进行全内反射，导光板304的网点307破坏该全内反射，从而使得光线从导光板304的出光面306射出。
进一步的，本实施例的侧入式背光模组300还包括：
光学膜片组309，设置于导光板304的上方，并且正对导光板304的出光面306；
胶框310，设于铝侪301的外侧，并且覆盖在光学膜片组309的四周边缘上，并且，在铝挤301与胶框310之间还至少部分设置有粘接条（图未示），粘接条用于固定胶框310、铝挤301及其他光学组件（图未示）。
进一步的，侧入式背光模组300还包括：
背板313，用于承载胶框310、铝挤301及其他光学组件；
PCB（印刷电路板）板315，设置于铝挤竖板302的内侧壁上，用于为侧入式背光源303提供电能，其中，侧入式背光源303设置于PCB板315上；
反射片312，设置于导光板304的出光面306与侧入式背光源303之间的间隙上，用于将侧入式背光源303发出的光反射至导光板304。
这里需要注意的是，侧入式背光模组300还包括了其他未图示的光学元件。
综上所述，区别于现有技术，本发明的液晶显示器，包括液晶显示面板及侧入式背光模组，其中，侧入式背光模组包括侧入式背光源，液晶显示面板包括多个呈阵列式排列且面积相等的像素单元，每个像素单元包括依序排列的红色、绿色及蓝色子像素，自远离该侧入式背光模组的方向上蓝色子像素的透光率逐渐增大，因此，本发明可以提高蓝色子像素的蓝光的穿透率，弥补侧入式背光模组中蓝光被吸收造成的色偏影响，降低液晶显示面板的色差。
以上参照附图说明了本发明的优选实施例，并非因此局限本发明的权利范围。本领域技术人员不脱离本发明的范围和实质内所作的任何修改、等同替换和改进，均应在本发明的权利范围之内。
