Abstract

Description

一种像素结构、显示面板及显示装置 技术领域
本申请涉及液晶显示技术领域，具体涉及一种像素结构、显示面板及显示装置。
背景技术
目前，市场对于液晶显示器的性能要求是朝向高对比(High Contrastratio)、无灰阶反转(No Gray Scale Inversion)、色偏小(little colorshift)、亮度高(High Luminance)、高色彩丰富度、高色饱和度、快速反应与广视角等特性。目前能够达成广视角要求的技术包括例如扭转向列型液晶(Twisted Nematic，TN)加上广视角膜(Wide Viewing Film)、共平面切换式(In-plane Switching，IPS)液晶显示器、边际场切换式(Fringe Field Switching)液晶显示器与多域垂直配向式(Multi-Domain Vertically Alignment，MVA)薄膜电晶体液晶显示器等方式。
对于现有的多域垂直配向式液晶显示器而言，由于配置于彩色滤光片基板或薄膜电晶体阵列基板上的配向凸起物(Alignment Protrusion)或狭缝(Slit)可以使得液晶分子呈多方向排列，得到数个不同的配向领域(Domain)，因此多域垂直配向式液晶显示器能够达成广视角的要求。多域垂直配向式液晶显示器所使用的像素结构容易导致出现褪色问题(Color Washout)，为解决褪色问题通常是增加像素结构中的配向领域，例如把四个配向领域增加为八个配向领域。但配向领域的增加会影响显示面板的穿透率，降低显示质量。

请参照图1至图3，所述像素结构300包括数据线310、扫描线320、开关元件330、第一电极层100以及第二电极层200。
其中，所述扫描线310与所述数据线320互相垂直，所述数据线310与所述扫描线320相互围合以形成像素区域340，所述像素区域340以矩阵形式排列于所述显示面板上；所述开关元件330与所述数据线300以及所述扫描线320电性连接。
具体实施中，所述数据线310、所述扫描线320与所述开关元件330可以设置于显示面板的第一基板或第二基板上。所述数据线310沿水平方向延伸、所述数据线310沿竖直方向延伸。所述开关元件330可以为薄膜晶体管(TFT，Thin Film Transistor)，然而不限于此。所述薄膜晶体管的栅极连接扫描线320、源极 连接数据线310、漏极连接所述像素电极。
所述第一电极层100设置于所述显示面板的第一基板上，包括第一片状电极110以及第一条状电极120；所述第一条状电极120包括至少两个第一条状结构121，任意两个相邻的第一条状结构121的宽度互不相等，每两个相邻第一条状结构121之间形成第一狭缝122；所述第一片状电极110所在区域为第一区域131，所有所述第一条状电极120以及所有所述第一狭缝122所在区域为第二区域132。
所述第二电极层200设置于与所述第一基板相对的第二基板上，包括第二片状电极210以及第二条状电极220；所述第二条状电极220包括至少两个第二条状结构221，任意两个相邻的第二条状结构221的宽度互不相等，每两个相邻第二条状结构221之间形成第二狭缝222；所述第二片状电极210所在区域为第三区域232，所有所述第二条状电极220以及所有所述第二狭缝222所在区域为第四区域231。
所述第二区域132与所述第四区域231相对设置且面积相等，所述第一区域131与所述第三区域232相对设置且面积相等；所述第一电极层和所述第二电极层的面积均小于或者等于所述像素区域的面积。
本申请实施例中，所述显示面板为液晶面板(Liquid Crystal Display，LCD)。所述液晶面板包括薄膜晶体管液晶显示面板(Thin Film Transistor-Liquid Crystal display，TFT-LCD)、扭转向列型液晶面板(Twisted Nematic，TN)、垂直配向式面板(Vertical Alignment，VA)、共平面切换式面板(In Plane Switching，IPS)、彩色滤光片整合晶体管式(Color Filter on Array，COA)面板等。
其中，所述显示面板为液晶面板(Liquid Crystal Display，LCD)。所述第一基板为阵列基板(Array Substrate)，所述第二基板为与所述第一基板相对设置的彩色滤光膜基板(CF Substrate)。或者所述第一基板为彩色滤光膜基板(CF Substrate)，所述第二基板为与所述第一基板相对设置的阵列基板(Array Substrate)。若所述第一基板为阵列基板(Array Substrate)，所述第二基板为与所述第一基板相对设置的彩色滤光膜基板(CF Substrate)，设置于第一基板上的第一电极层100作为该像素结构300中的像素电极，设置于第二基板上的第二电极层200作为该像素结构300中的公共电极。所述第一电极层100与所述第二电极层200之间可形成电压差，以驱动显示面板中的液晶分子。
具体实施中，可通过根据实际生产调试结果对第二区域132与第四区域231面积大小进行调整，进而获取改善显示面板褪色问题(Color Washout)的较佳面积比例。例如，所述第二区域132与所述第四区域231的面积比例为1∶1，即所述第二区域132与所述第四区域231相对设置且面积相等。相对应地，所述第一区域131与所述第三区域232的面积比例同样为1∶1，即所述第一区域131与所述第三区域232相对设置且面积相等。特别地，所述第一区域131与所述第二区域132的面积相同。所述第三区域232与所述第四区域231的面积相同。
在一些实施例中，所述第二区域132与所述第四区域231的面积比例还可以为1∶2，对应地，所述第一区域131与所述第三区域232的面积比例为2∶1。本申请实施例并不对所述第二区域132与所述第四区域231的面积比例进行限定。
在一些实施例中，所述第一电极层100以及第二电极层200可以由铟锡氧化物、铟锌氧化物等透明导电材料制成。通过铟锡氧化物、铟锌氧化物等材料透光特性，可以大大提高像素结构300的开口率，进而提升显示面板的穿透率。本申请并不对所述第一电极层100以及第二电极层200的材料作出限定。
在一些实施例中，所述第一电极层100与所述第二电极层200分别设置于两个对向的基板上，两者相互重叠且位于所述像素区域340内。
在一些实施例中，所述第一条状结构121和所述第二条状结构221均以至少两个延伸角度进行延伸。例如，所述第一条状结构121和所述第二条状结构221均以四个延伸角度进行延伸，所述延伸角度包括45°、135°、225°以及315°。所述延伸角度为所述第一条状结构121以及所述第二条状结构221与所述扫描线320的夹角大小。
在一些实施例中，所述像素区域340包括至少两个像素子区域，所述像素子区域的数量与所述延伸角度的数量相等；位于同一个所述像素子区域中的所述第一条状结构121的延伸角度与所述第二条状结构221的延伸角度相等。例如，假设所述延伸角度包括45°、135°、225°以及315°这四个角度，则所述像素区域340可划分为四个像素子区域。通过不同延伸角度的条状结构所形成的不同的像素子区域，在第一基板与第二基板形成电压差的时候，可使液晶分子长轴将分别向相对于水平方向倾斜45°、135°、-45°、及-135°方向倒伏。
在一些实施例中，第一条状结构121的宽度大于与所述第一条状结构121相邻的第一狭缝122的宽度的50％。
具体地，第一条状结构121与第一狭缝122间隔设置于第一电极层100。每一个第一条状结构121至少存在一个与其相邻的第一狭缝122。例如，若第一条状结构121的宽度为4微米，且与该第一条状结构121相邻的第一狭缝122的数量为两个，则任意一个与该第一条状结构121相邻的第一狭缝122的宽度小于8微米。特别地，第一条状结构121的宽度为与该第一条状结构121相邻的第一狭缝122的宽度的1.25倍。同理，第二条状结构221的宽度大于与所述第二条状结构221相邻的第二狭缝222的宽度的50％。实施本申请实施例，可防止出现因为第一狭缝122或者第二狭缝222的宽度过高，而导致夹设于第一电极层100与第二电极层200之间的液晶分子的转向灵敏度降低。
在一些实施例中，同一个像素子区域的第一条状结构121或者第二条状结构221的宽度由中部向边缘逐渐变小。
具体地，同一个像素子区域的第一条状结构121或者第二条状结构221的宽度按照预设的排列顺序进行排列。例如，同一个像素子区域的第一条状结构121或者第二条状结构221的宽度由中部向边缘逐渐变小。特别地，同一个像素子区域的任意两个相邻的第一条状结构121的宽度互不相等。于其他实施例，同一个像素子区域的第一条状结构121或者第二条状结构221的宽度按逆时针方向逐渐变小；或者同一个像素子区域的第一条状结构121或者第二条状结构221的宽度按逆时针方向逐渐变大。本申请实施例并不对同一个像素子区域的第一条状结构121或者第二条状结构221对应的预设的排列顺序进行限制。
在一些实施例中，同一个像素子区域的第一狭缝122或者第二狭缝222的宽度由中部向边缘逐渐变小。
具体地，同一个像素子区域的第一狭缝122或者第二狭缝222的宽度按照预设的排列顺序进行排列。例如，同一个像素子区域的第一狭缝122或者第二狭缝222的宽度由中部向边缘逐渐变小。特别地，同一个像素子区域的任意两个相邻的第一狭缝122的宽度互不相等。于其他实施例，同一个像素子区域的第一狭缝122或者第二狭缝222的宽度按逆时针方向逐渐变小；或者同一个像素子区域的第一狭缝122或者第二狭缝222的宽度按逆时针方向逐渐变大。本申请实施例并不对同一个像素子区域的第一狭缝122或者第二狭缝222对应的 预设的排列顺序进行限制。
本申请实施例通过将包括有条状结构的电极层分别设置于显示面板中的第一基板以及第二基板上，以控制显示面板中液晶分子的排列方向，进而得到数个不同的配向领域，以实现显示面板的广视角效果。同时，该像素结构300有利于改善显示面板的穿透率，增强显示质量。
请参照图4，其为本申请一实施例中一种显示面板的结构示意图。所述显示面板400包括第一基板410、第二基板420、液晶层430，以及像素结构300。
本申请实施例中，所述显示面板包括但不限于液晶显示面板(Liquid Crystal Display，LCD)、有机发光二极管显示面板(Organic Light-Emitting Diode，OLED)、场发射显示面板(Field emission display，FED)、等离子显示面板PDP(Plasma Display Panel)、曲面型面板。所述液晶面板包括薄膜晶体管液晶显示面板(Thin Film Transistor-Liquid Crystal display，TFT-LCD)、TN面板(Twisted Nematic+Film)、VA类面板(Vertical Alignment)、IPS面板(In Plane Switching)、COA(Color Filter on Array)面板等。
