Abstract

一种背光驱动方法、显示驱动方法、驱动装置及显示装置。该背光驱动方法包括：接收一帧背光数据，该背光数据包括分别用于多个开关通道作为开关控制信号的多个第一控制信号以及与多个第一控制信号分别对应的多个第二控制信号组，每个第二控制信号组包括分别用于多个输出通道作为输出控制信号的多个第二控制信号，多个第一控制信号各自为调制的非等宽脉冲信号；以及，使用多个第一控制信号和多个第二控制信号组驱动背光单元发光。该背光驱动方法可以对开关控制信号的脉冲宽度进行实时配置，可以用于增加相邻的开关控制信号之间的时间间隔，以减小出现鬼影现象的几率，或者也可以用于变相增加相邻帧之间的时间间隔，以减小出现动态模糊现象的几率。
