Title
(EN) Method for driving display, and a photoelectric device
(ZH) 一种液晶显示器的驱动方法及一种光电装置
Abstract
(EN)
A driving method of display includes sending multiple grid signal to drive switch component, sending multiple data signal for providing pixel voltage to unit pixel to generate voltage difference, controlling voltage difference sum of each unit pixel at group time to be zero, displaying at least one group pixel in each driving unit time and containing multiple brightness grey level value in group pixel, making said brightness grey level value be consistency to an expected value for not only increasing visual angle of display but also avoiding ghost on display.

本发明公开了一种液晶显示器的驱动方法及一种光电装置,该显示器具有多个单位像素,每个单位像素都包含一个开关组件,开关组件用于控制该单位像素显示,驱动方法包括发送多个栅极信号至该开关组件,以驱动该开关组件,及发送多个不同亮度表现的数据信号至该开关组件,提供多个像素电压至该单位像素,而与该单位像素的共同电压产生电压差,以在一群组时间控制该单位像素显示,每一单位像素在群组时间所受的电压差总和为零,其中群组时间包含多个驱动单位时间,每一驱动单位时间显示至少一群组像素,群组像素包含多个亮度灰阶值,该亮度灰阶值的总亮度值符合一预期亮度值,这样除可让显示器增加显示视角之外,还可避免因残留电荷而导致残影现象产生。
