Title
(EN) OVERCURRENT PROTECTION CIRCUIT AND DISPLAY DRIVE DEVICE
(FR) CIRCUIT DE PROTECTION CONTRE LES SURINTENSITÉS ET DISPOSITIF DE COMMANDE D'AFFICHAGE
(ZH) 过流保护电路及显示驱动装置
Abstract
(EN)
An overcurrent protection circuit and display drive device, comprising: when input current of a front end corresponding to a logic signal experiences overcurrent, preventing the input current of the front end experiencing overcurrent from being transmitted to a drive chip, thereby preventing damage to the drive chip.
(FR)
L'invention concerne un circuit de protection contre les surintensités et un dispositif de commande d'affichage, consistant : lorsque le courant d'entrée d'une extrémité avant correspondant à un signal logique subit une surintensité, à empêcher le courant d'entrée de l'extrémité avant subissant une surintensité d'être transmis à une puce d'attaque, empêchant ainsi un endommagement de la puce d'attaque.
(ZH)
一种过流保护电路及显示驱动装置包括:在逻辑信号对应的前端输入电流出现过流时,防止过流的前端输入电流传输至驱动芯片,避免驱动芯片的损坏。
