Description
本发明涉及显示技术领域，尤其涉及显示驱动方法及液晶显示装置。
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（PDA）、数字相机、计算机屏幕或笔记本电脑屏幕等，在平板显示领域中占主导地位。
现有市场上的液晶显示器大部分为背光型液晶显示器，其包括液晶显示面板及背光模组（backlight module）。液晶显示面板的工作原理是在薄膜晶体管阵列基板（Thin Film Transistor Array Substrate，TFT Array Substrate）与彩色滤光片基板（Color
Filter，CF）之间灌入液晶分子，并在两片基板上施加驱动电压来控制液晶分子的旋转方向，以将背光模组的光线折射出来产生画面。
由于液晶分子有光学的各向异性特性，现有液晶显示面板存在色度可视角窄，影响了人们在大视角下的观看体验的问题。为了实现提升液晶显示面板的色度可视角窄，现有技术提出了多畴像素结构，多畴像素结构就是将每个子像素均细分成更小的区域（畴），使得每一区域内的液晶会向不同方向，典型的例如四畴结构，即将一个子像素的像素电极制作成“米”字形，使得像素电极被分为四个区域，驱动时，每一个区域内的液晶会向不同方向，进一步地，对四畴结构进行改进，还提出一种八畴结构，即将一个子像素的像素电极先分为主区像素电极（Main）及次区像素电极（Sub），主区像素电极与次区像素电极均为“米”字形电极，且施加到主区像素电极与次区像素电极的驱动电压成一定的比例，从而使得一个子像素中形成八个畴，相比于四畴结构能够进一步地提升视角。
虽然，具有八畴结构子像素的液晶显示面板相对于具有四畴结构子像素的液晶显示面板其色度可视角有了显著的提高，但与平面转换（In-Plane
Switching， IPS）模式的液晶显示面板以及有机发光二极管（Organic
Light-Emitting Diode，OLED）显示面板相比，其色度可视角仍然非常低，从而影响了人们在大视角下的观看体验。
