Abstract

一种驱动器(200)、显示装置及其光学补偿方法，显示装置包括驱动器(200)和显示面板(100)，显示面板(100)包括阵列分布的多个子像素(110)；光学补偿方法包括：向驱动器(200)输入第一预设画面的各个子像素(110)的初始灰阶，其中，在第一预设画面中，任意电连接于同一数据线上且位于相邻两行的两个子像素的初始灰阶的差值的绝对值大于预设阈值(S111)；获取显示面板(100)中各个子像素(110)的初始亮度(S113)；根据各个子像素(110)的初始灰阶和各个子像素(110)的初始亮度，确定各个子像素(110)的第一补偿参数(S120)；将各个子像素(110)的第一补偿参数存储于驱动器(200)中(S130)。该驱动器(200)、显示装置及其光学补偿方法，能够提高子像素(110)的充电率。
