Description
本发明涉及显示技术领域，尤其涉及一种显示面板驱动方法。
薄膜晶体管（Thin Film Transistor，TFT）是目前液晶显示装置（Liquid Crystal Display，LCD）和有源矩阵驱动式有机电致发光显示装置（Active Matrix Organic Light-Emitting
Diode，AMOLED）中的主要驱动元件，直接关系平板显示装置的显示性能。
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（Color
Filter，CF）基板之间灌入液晶分子，并在两片基板上分别施加像素电压和公共电压，通过像素电压和公共电压之间形成的电场控制液晶分子的旋转方向，以将背光模组的光线透射出来产生画面。
随着人们对显示品质的不断追求，高刷新率（例如120HZ）和高画质（例如8K）的液晶显示器必然会成为以后的发展趋势，然而高刷新率和高画质的液晶面板必然会造成源极驱动器负载（loading）的加重，为了实现相邻行像素的亮暗交替，需要源极驱动器传输给数据线的数据信号在低灰阶电压与高灰阶电压之间频繁切换的时候，由于切换前后的压差很大，会导致源极驱动器的温度过高，从而源极驱动器造成损伤，使其无法正常工作；除此之外，在亮暗交替的重载画面下也会造成大量电流的消耗，增加了功耗。
目前现有技术中可以通过重载画面数据补偿方式将重载画面转换成较轻载画面，从而降低源极驱动器负载。由于重载画面数据补偿算法的前提是不能改变非重载画面的显示，同时考虑到算法的成本，无论在1G1D结构（即一条扫描线对应一行子像素，一条数据线对应一列子像素）还是1G1D+filp（翻转）架构（即一条扫描线对应一行子像素，一条数据线相邻两列子像素），数据补偿的幅度均是同一条数据线上相邻两次的数据跳变的重载程度决定（例如同一条数据线的数据由0灰阶电压跳变到255灰阶电压，再从255阶电压跳变到0灰阶电压，两次均为最重载跳变，故数据补偿的幅度也最大），但是重载画面数据补偿方式会将一些非重载画面误侦测后修改，然而这些非重载画面为LCD面板驱动开发中的重要检验画面，所以重载画面数据补偿方式对这些非重载画面的开发带来困难。
本发明的目的在于提供一种显示面板驱动方法，防止对非重载画面进行误补偿而改变非重载画面的显示，提高补偿的准确性。
为实现上述目的，本发明提供了一种显示面板驱动方法，包括如下步骤：
步骤S1、提供显示面板；该显示面板包括呈阵列分布的多个子像素；
步骤S2、获得显示面板第x帧显示画面中的第i-2行子像素、第i-1行子像素、第i行子像素及第i+1行子像素的亮度值，设x，i均为正整数，且i>=3；
步骤S3、通过重载画面亮度值补偿算法对第x帧显示画面进行亮度值补偿时，当第i-2行子像素与第i行子像素的亮度值均大于或等于预设的第一亮度值，第i-1行子像素与第i+1行子像素的亮度值均小于或等于预设的第二亮度值，且所述第一亮度值大于第二亮度值，则判断第x帧显示画面为重载画面，对第i-1行子像素进行亮度值补偿，否则，则判断第x帧显示画面为非重载画面，不对子像素进行亮度值补偿。
所述非重载画面包括“田”字形显示画面，该“田”字形显示画面中的一行子像素和一列子像素的亮度值均大于或等于预设的第一亮度值，其余的子像素的亮度值均小于或等于预设的第二亮度值。
