Title
(EN) PIXEL DRIVE CIRCUIT AND DISPLAY PANEL
(FR) CIRCUIT D'ATTAQUE DE PIXEL ET PANNEAU D'AFFICHAGE
(ZH) 像素驱动电路及显示面板
Abstract
(EN)
Disclosed are a pixel drive circuit and a display panel. A pixel drive circuit of 3T2C structure is used for effectively compensating the threshold voltage (Vth) of a drive transistor in each pixel. The pixel drive circuit has a simple compensation structure and does not occupy too much area in design.
(FR)
L'invention concerne un circuit d'attaque de pixel et un panneau d'affichage. Un circuit d'attaque de pixel de structure 3T2C est utilisé pour compenser efficacement la tension de seuil (Vth) d'un transistor d'attaque dans chaque pixel. Le circuit d'attaque de pixel a une structure de compensation simple et n'occupe pas trop d'espace dans la conception.
