Title
(EN) EOA CIRCUIT, DISPLAY PANEL, AND TERMINAL
(FR) CIRCUIT EOA, ÉCRAN D'AFFICHAGE, ET TERMINAL
(ZH) 一种EOA电路、显示面板及终端
Abstract
(EN)
An EOA circuit, a display panel, and a terminal. The EOA circuit comprises: an output module (10) being used for generating an output signal (Eout) according to a first scanning signal (Gn) and a clock signal (ECKB), and the output module (10) being further used for resetting the output signal (Eout) from a high level signal to a low level signal when the first scanning signal (Gn) is in an active level and the clock signal (ECKB) is in an inactive level; and a control module (20) for restoring the output signal (Eout) from the low level signal to the high level signal according to a second scanning signal (Gn-2) when the first scanning signal (Gn) is in the inactive level. The EOA circuit has a simple structure and small space occupation, and facilitates a narrow-bezel design.
(FR)
L'invention concerne un circuit EOA, un écran d'affichage, et un terminal. Le circuit EOA comprend : un module de sortie (10) servant à générer un signal de sortie (Eout) en fonction d'un premier signal de balayage (Gn) et d'un signal d'horloge (ECKB), et le module de sortie (10) étant en outre utilisé pour réinitialiser le signal de sortie (Eout) à partir d'un signal fort au profit d'un signal faible lorsque le premier signal de balayage (Gn) est à un niveau actif et le signal d'horloge (ECKB) est dans un niveau inactif; et un module de commande (20) pour restaurer le signal de sortie (Eout) depuis le signal faible au profit du signal fort en fonction d'un second signal de balayage (Gn-2) lorsque le premier signal de balayage (Gn) est dans le niveau inactif. Le circuit EOA a une structure simple et une faible occupation d'espace, et facilite une conception à lunette étroite.

一种EOA电路、显示面板及终端,该EOA电路包括:输出模块(10),用于根据第一扫描信号(Gn)和时钟信号(ECKB)生成输出信号(Eout);输出模块(10)还用于在第一扫描信号(Gn)为有效电平期间且时钟信号(ECKB)为无效电平期间,将输出信号(Eout)由高电平信号重置为低电平信号;控制模块(20),用于在第一扫描信号(Gn)为无效电平期间,根据第二扫描信号(Gn-2),将输出信号(Eout)由低电平信号恢复至高电平信号。该EOA电路结构简单,占用空间小,有利于窄边框设计。
