显示装置及其驱动方法和电子设备
摘要：
本发明的显示装置可根据视频信号的色调来进行适当的迁移率校正，提高画面的均匀性。写扫描器(4)具有移位寄存器(S/R)和输出缓冲器(4B)。移位寄存器(S/R)与线依次扫描同步地对移位寄存器的各个级依次生成输入信号(IN，AZX)。输出缓冲器(4B)连接到移位寄存器的各个级和各个扫描线(WS)之间，根据输入信号(IN，AZX)对扫描线(WS)输出控制信号。输出缓冲器(4B)根据输入信号(IN，AZX)使用于规定采样晶体管的截止定时的控制信号(OUT)的下降波形至少以二阶地变化，并根据视频信号的信号电平而对迁移率校正期间进行可变控制。
摘要（英）：

A display device of this invention is capable of properly correcting the migration rate based on a video signal and improving the image evenness. A writing scanner (4) comprises a shift register (S/R) and an output buffer (4B). The shift register (S/R) is synchronous with a line order scanning so as to generate input signals (IN, AZX) to each level order of the shift register. The output buffer (4B) is connected between each level an each scanning line (WS) of the shift register (S/R) and outputs a control signal to the scanning line (WS) based on input signals (IN, AZX). The output buffer (4B) changes the decline of the control signal (OUT) for stopping the time of specified sampling transistor based on the level change of the input signals (IN, AZX) along the waveform in two stages, such that the changeable control to the migration rate correction period based on the signal level of the video signal.
