Description

像素驱动方法
技术领域
本发明涉及显示技术领域，尤其涉及一种像素驱动方法。
背景技术
薄膜晶体管(Thin Film Transistor，TFT)是目前液晶显示装置(Liquid CrystalDisplay，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(ThinFilm Transistor Array Substrate，TFT Array Substrate)与彩色滤光片(ColorFilter，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。
目前，为了进一步推动液晶电视的普及，液晶面板不断的追求低成本和高品质。为了降低成本，双栅(Dual-gate)架构的显示面板成为一种有效的方案，如图1所示，该双栅架构的显示面板包括呈阵列排布的多个子像素10’、沿水平方向延伸的多条扫描线20’以及沿竖直方向延伸的多条数据线30’。每两条扫描线20’对应连接一行子像素10’；每相邻两列子像素10’分别交错连接到与该相邻两列子像素10’左右相邻的数据线30’。因此该双栅架构的显示面板可以大大减少源极驱动器(source driver)的数量(例如4条数据线30’可对应连接6列子像素10’)，从而减少整个液晶面板的成本。
虽然双栅架构的显示面板虽然通过减少源极驱动器的数量实现了成本的降低，但是显示面板的扫描速率提升了一倍，更快的扫描速度必然会造成源极驱动器负载(driverIC loading)的加重，特别是在重载画面下(例如所有红色子像素和蓝色子像素的灰阶均为0，所有绿色子像素的灰阶均为255)，源极驱动器温度具有过高的风险，从而对源极驱动器温度造成不可逆的损伤，使其无法正常工作。而目前主要通过增加散热片的方法来解决重载画面下源极驱动器温度过高的问题，但散热片的增加无疑会导致成本的增加。
发明内容
本发明的目的在于提供一种像素驱动方法，可以在不增加成本的情况下解决重载画面下源极驱动器温度过高的问题。
为实现上述目的，本发明提供了一种像素驱动方法，包括如下步骤：

步骤S3、通过亮度补偿值计算公式获得第j行第i列子像素的亮度补偿值；
步骤S4、根据第j行第i列子像素的目标亮度值及亮度补偿值，通过补偿后的亮度值计算公式输出第j行第i列子像素补偿后的亮度值；
