Abstract
(EN)
A display drive device, a display device, and a display module. The display drive device comprises: a drive controller (13) for outputting a drive control signal and performing drive control on a display pixel; and an auxiliary control circuit (14) for connecting to an output end of the drive controller (13) when the signal of the drive controller (13) is output abnormally, and outputting an auxiliary control signal to perform drive control on the display pixel.
(FR)
La présente invention concerne un procédé de pilotage d’affichage ainsi qu'un dispositif et un module d'affichage. Le dispositif de pilotage d'affichage comprend : un dispositif de commande de pilotage (13) destiné à délivrer un signal de commande de pilotage et à appliquer une commande de pilotage à un pixel d'affichage ; et un circuit de commande auxiliaire (14) destiné à se connecter à une extrémité de sortie du dispositif de commande de pilotage (13) lorsque le signal du dispositif de commande de pilotage (13) est délivré de manière anormale, et à délivrer un signal de commande auxiliaire permettant d'appliquer une commande de pilotage au pixel d'affichage.
