Abstract
(EN)
A gate drive circuit based on temperature compensation and a display device, the gate drive circuit being used in a liquid crystal panel, and comprising: a direct current voltage source (101), a voltage division unit (102), an amorphous silicon thin film transistor (103), a power source management module (104), and a gate drive module (105); the power source management module (104) adjusts the voltage value outputted to the gate drive module (105) on the basis of the voltage change of a common node, thereby adjusting the gate drive voltage of the pixel units of the display panel.
(FR)
L'invention concerne un circuit de commande de grille basé sur une compensation de température, ainsi qu'un dispositif d'affichage, le circuit de commande de grille étant utilisé dans un panneau à cristaux liquides et comprenant : une source de tension continue (101), une unité de division de tension (102), un transistor à couches minces de silicium amorphe (103), un module de gestion de source d'alimentation (104), ainsi qu'un module de commande de grille (105) ; le module de gestion de source d'alimentation (104) règle la valeur de tension émise en sortie vers le module de commande de grille (105) en fonction du changement de tension d'un noeud commun, ce qui règle la tension de commande de grille des unités de pixels du panneau d'affichage.
