Description

UV2A像素结构
技术领域
本发明涉及显示技术领域，尤其涉及一种UV2A像素结构。
背景技术
液晶显示器(Liquid Crystal Display，LCD)具有机身薄、省电、无辐射等众多优点，得到了广泛的应用，如液晶电视、移动电话、个人数字助理、数字相机、计算机屏幕或笔记本电脑屏幕等。现有的液晶显示器大部分为背光型液晶显示器，其包括壳体、设于壳体内的液晶面板及设于壳体内的背光模组。通常液晶面板由一彩色滤光片基板(Color Filter，CF)、一薄膜晶体管阵列基板(Thin Film Transistor Array Substrate，TFT Array Substrate)以及一填充于两基板间的液晶层(Liquid Crystal Layer)所构成，其工作原理是通过在CF基板和TFT基板上施加驱动电压来控制液晶层的液晶分子的旋转，控制光的输出量，将背光模组的光线折射出来产生画面。
就目前主流市场上的TFT-LCD液晶面板而言，可分为三大类，分别是扭曲向列/超扭曲向列(TN/STN)型、平面转换(IPS)型及垂直配向(VA)型。在液晶显示面板的制作过程中，进行导向膜配向是一项重要工艺，通过配向工艺来实现液晶分子按照特定的方向与角度排列。传统的配向工艺采用摩擦(Rubbing)法，只能在一个水平方向上配向，被TN型、IPS型的液晶面板广泛采用。但VA型的液晶面板需要扩大视角，将子像素分割成多个区域，每一区域内的配向方向不同，因此不能采用摩擦法。
紫外线诱导多区域垂直配向(ultraviolet induced multi-domain verticalalignment，UV2A)为VA型液晶面板的一种光配向技术。如图1所示，UV2A利用紫外线以一定的角度斜射到配向膜(PI)10上，在配向膜10的表面形成一定倾斜角度的配向微结构20，从而使液晶分子30在配向膜10表面有一个预倾角度。经UV2A配向后，配向膜10表面形成的配向微结构20与紫外线倾斜的角度一致，配向精度较高。
随着液晶显示技术的发展，高解析度液晶面板(如4K2K，8K4K)成为了当前的热点产品，但高解析度液晶面板的开口率较低，使得透射光占入射光光强的百分量(T％)、及光线透过率较低。考虑到VA型液晶面板的视角问题，现有的UV2A像素结构一般如图2所示，将每个像素单元100中的红色子像素101、绿色子像素102、及蓝色子像素103分别划分成四个相同大小的配向子区域，且同一子像素中相邻两配向子区域间的配向方向相互垂直。然而此种UV2A像素结构会在每一子像素的四个配向子区域之间的交界处形成十字暗纹，影响光线透过率。
发明内容
本发明的目的在于提供一种UV2A像素结构，能够减少每一子像素内的暗纹，提高光线透过率，并降低液晶面板的制程难度，提高生产效率，节省生产成本。
为实现上述目的，本发明提供一种UV2A像素结构，包括多个呈阵列式排布的像素单元，每一像素单元包括三个并行排列的子像素，依次为红色子像素、绿色子像素、及蓝色子像素；所述红色子像素、绿色子像素、及蓝色子像素分别由单个配向子区域、或两个配向方向相互垂直的配向子区域构成；相邻两个子像素中对应的配向子区域的配向方向相互垂直，或相邻两个像素单元中对应的子像素的配向子区域的配向方向相互垂直。
所述红色子像素、绿色子像素、及蓝色子像素分别由左、右两个配向方向相互垂直的配向子区域构成，上、下相邻的两个像素单元中对应的子像素的配向子区域的配向方向相互垂直。
所述红色子像素、绿色子像素、及蓝色子像素分别由上、下两个配向方向相互垂直的配向子区域构成，左、右相邻的两个像素单元中对应的子像素的配向子区域的配向方向相互垂直。
所述红色子像素、绿色子像素、及蓝色子像素分别由上、下两个配向方向相互垂直的配向子区域构成，左、右相邻的两个子像素中对应的配向子区域的配向方向相互垂直。
所述红色子像素、绿色子像素、及蓝色子像素分别由单个配向子区域构成，上、下相邻及左、右相邻的两个子像素的配向子区域的配向方向相互垂直。
所述红色子像素、绿色子像素、及蓝色子像素分别由单个配向子区域构成，上、下相邻及左、右相邻的两个像素单元中对应的子像素的配向子区域的配向方向相互垂直。
同一子像素中，所述两个配向方向相互垂直的配向子区域的面积相等。
所述配向方向与水平方向的夹角为45°或-45°。
本发明的有益效果：本发明提供的一种UV2A像素结构，每一像素单元中的各个子像素分别由单个配向子区域、或两个配向方向相互垂直的配向子区域构成，能够减少每一子像素内配向子区域交界处的暗纹，通过设置相邻两个子像素中对应的配向子区域的配向方向相互垂直，或相邻两个像素单元中对应的子像素的配向子区域的配向方向相互垂直来进行视角补偿，提高了光线透过率，降低了制程难度，提高了生产效率，降低了液晶面板的生产成本。

相比现有的每一子像素由四个配向子区域构成的UV2A像素结构，该第四实施例中每一子像素的配向子区域的数量减少至一个，不存在因配向子区域交界而产生的暗纹，从而能够提高光线透过率，降低制程难度，提高生产效率，降低液晶面板的生产成本。设置上、下相邻及左、右相邻的两个子像素的配向子区域的配向方向相互垂直，能够补偿视角，保证显示效果。
图7所示为本发明的UV2A像素结构的第五实施例。该第五实施例中，所述红色子像素11、绿色子像素12、及蓝色子像素13分别由单个配向子区域构成。所述单个配向子区域的配向方向与水平方向的夹角为45°或-45°。上、下相邻及左、右相邻的两个像素单元1中对应的子像素的配向子区域的配向方向相互垂直。
相比现有的每一子像素由四个配向子区域构成的UV2A像素结构，该第五实施例中每一子像素的配向子区域的数量减少至一个，不存在因配向子区域交界而产生的暗纹，从而能够提高光线透过率，降低制程难度，提高生产效率，降低液晶面板的生产成本。设置上、下相邻及左、右相邻的两个像素单元1中对应的子像素的配向子区域的配向方向相互垂直，能够补偿视角，保证显示效果。
值得一提的是，本发明的UV2A像素结构在正视角下与现有的每一子像素由四个配向子区域构成的UV2A像素结构的显示效果相同，且在大视角下，相邻子像素或相邻像素单元之间也会补偿色偏，尽管本发明的UV2A像素结构会有解析度下降的问题，但对于高解析度的液晶面板来说，大视角下解析度的下降对观赏效果影响轻微。
综上所述，本发明的UV2A像素结构，每一像素单元中的各个子像素分别由单个配向子区域、或两个配向方向相互垂直的配向子区域构成，能够减少每一子像素内配向子区域交界处的暗纹，通过设置相邻两个子像素中对应的配向子区域的配向方向相互垂直，或相邻两个像素单元中对应的子像素的配向子区域的配向方向相互垂直来进行视角补偿，提高了光线透过率，降低了制程难度，提高了生产效率，降低了液晶面板的生产成本。
以上所述，对于本领域的普通技术人员来说，可以根据本发明的技术方案和技术构思作出其他各种相应的改变和变形，而所有这些改变和变形都应属于本发明后附的权利要求的保护范围。
