Title (EN) REPAIR CIRCUIT, DISPLAY SUBSTRATE AND CORRESPONDING DISPLAY PANEL AND REPAIR METHOD
(FR) CIRCUIT DE RÉPARATION, SUBSTRAT D'AFFICHAGE ET PANNEAU D'AFFICHAGE ET PROCÉDÉ DE RÉPARATION CORRESPONDANTS
(ZH) 修复电路、显示基板以及相应的显示面板和修复方法
Abstract:
(EN) Provided are a repair circuit (5), a display substrate, a corresponding display panel, and a corresponding repair method. The repair circuit (5) comprises: a repair unit (6); and at least three repair lines electrically connected to the repair unit (6). The repair unit (6) comprises: a charging module (61); an input module (62); and a pull-down module (63). The charging module (61) is configured to perform a charging operation when a first repair line (71) transmits a first level signal, and perform a discharging operation when transmission of the first level signal completes. The input module (62) is configured to provide a first driving signal to a second repair line (72) when the charging module (61) performs the discharging operation. The pull-down module (63) is configured to pull down a discharging level of the charging module (61) and pull down a level outputted by the input module (62) when a third repair line (73) transmits the first level signal. By performing a weld-connection operation at a corresponding repair point (8) and inputting signals via the repair unit, signals intended to be transmitted by a disconnected driving wire (3) are re-loaded to a grid line (4) connected to the disconnected driving wire (3), thereby realizing normal operation of a display panel.
(FR) L'invention concerne un circuit de réparation (5), un substrat d'affichage, un panneau d'affichage correspondant, et un procédé de réparation correspondant. Le circuit de réparation (5) comprend : une unité de réparation (6) ; et au moins trois lignes de réparation connectées électriquement à l'unité de réparation (6). L'unité de réparation (6) comprend : un module de charge (61) ; un module d'entrée (62) ; et un module d'abaissement (63). Le module de charge (61) est configuré pour effectuer une opération de charge lorsqu'une première ligne de réparation (71) émet un premier signal de niveau, et effectuer une opération de décharge lorsque l'émission du premier signal de niveau se termine. Le module d'entrée (62) est configuré pour fournir un premier signal de commande à une deuxième ligne de réparation (72) lorsque le module de charge (61) effectue l'opération de décharge. Le module d'abaissement (63) est configuré pour abaisser un niveau de décharge du module de charge (61) et abaisser un niveau délivré en sortie par le module d'entrée (62) lorsqu'une troisième ligne de réparation (73) émet le premier signal de niveau. Par la réalisation d'une opération de connexion-soudage à un point de réparation correspondant (8) et par entrée de signaux par l'intermédiaire de l'unité de réparation, des signaux destinés à être émis par un fil de commande déconnecté (3) sont rechargés vers une ligne de grille (4) connectée au fil de commande déconnecté (3), ce qui permet de réaliser un fonctionnement normal d'un panneau d'affichage.
(ZH) 一种修复电路(5)、显示基板以及相应的显示面板和修复方法,修复电路(5)包括修复单元(6)以及与修复单元(6)电连接的至少三条修复线(7),修复单元(6)包括充电模块(61)、输入模块(62)以及下拉模块(63),其中,充电模块(61)用于在第一修复线(71)传输第一电平信号时充电,并在第一修复线(71)传输第一电平信号结束后进行放电;输入模块(62)用于将在充电模块(61)进行放电时,向第二修复线(72)提供第一驱动信号;以及下拉模块(63)用于第三修复线(73)传输第一电平信号时,拉低充电模块(61)的放电电平及拉低输入模块(62)输出的电平。通过相应修复点(8)的熔接和修复单元信号的输入,使得断路的驱动引线(3)传输的信号重新加载到与之相连的栅线(4)上,从而实现显示面板的正常使用。
