Title (EN) DRIVING CIRCUIT AND DRIVING METHOD FOR DISPLAY DEVICE
(FR) CIRCUIT D'ATTAQUE ET PROCÉDÉ D'EXCITATION DE PANNEAU D'AFFICHAGE
(ZH) 一种显示装置的驱动电路和驱动方法
Abstract:
(EN) A driving circuit (100) and a driving method for a display device. The display device comprises a driving module (201) and a display panel (202). The driving circuit (100) comprises: a number N of single-ended conversion differential modules (101, 102, ..., 10N), connected with N signal output lines (G1, G2, ..., GN) of the driving module (201) and 2N scanning lines (G1', G2', ..., G2N') of the display panel (202) and accessing a clock signal, wherein each of the single-ended conversion differential modules (101, 102, ..., 10N) is correspondingly connected with one signal output line (G1, G2, ... ..., GN) and two scanning lines (G1', G2', ..., G2N'). The N single-ended conversion differential modules (101, 102, ..., 10N) are used to output, according to the clock signal, to the 2N scanning lines ( G1', G2', ..., G2N') scanning signals output by the N signal output lines (G1, G2, ..., GN) to charge the 2N scanning lines (G1', G2', ..., G2N') by means of the N signal output lines (G1, G2, ..., GN). N≥1 and N is a positive integer. The number of the driving modules (201) can be reduced, thereby effectively reducing the production cost of the display device.
(FR) L'invention concerne un circuit d'attaque (100) et un procédé d'excitation d'un dispositif d'affichage. Le dispositif d'affichage comprend un module d'attaque (201) et un panneau d'affichage (202). Le circuit d'attaque (100) comprend : un nombre N de modules différentiels de conversion asymétrique (101, 102, 10N) raccordés à N lignes de sortie de signaux (G1, G2, GN) du module d'attaque (201) et à 2N lignes de balayage (G1 ', G2', G2N') du panneau d'affichage (202), et accédant à un signal d'horloge, chaque module différentiel de conversion asymétrique (101, 102, 10N) étant relié de ce fait à une ligne de sortie de signaux (G1, G2, GN) et à deux lignes de balayage (G1', G2', G2N'). Les N modules différentiels de conversion asymétrique sont utilisés pour délivrer aux 2N lignes de balayage (G1', G2', G2N'), en fonction du signal d'horloge, des signaux de balayage émis par les N lignes de sortie de signaux (G1, G2, GN) pour charger les 2N lignes de balayage (G1', G2', G2N') au moyen des N lignes de sortie de signaux (G1, G2, GN), N étant un nombre entier positif supérieur ou égal à 1. Le nombre de modules d'attaque (201) peut être réduit, ce qui réduit efficacement le coût de production du dispositif d'affichage.
(ZH) 一种显示装置的驱动电路(100)和驱动方法,显示装置包括驱动模块(201)和显示面板(202),驱动电路(100)包括:N个单端转差分模块(101,102,……,10N),与驱动模块(201)的N条信号输出线(G1,G2,……,GN)和显示面板(202)的2N条扫描线(G1',G2',……,G2N')连接并接入时钟信号,每个单端转差分模块(101,102,……,10N)对应连接一条信号输出线(G1,G2,……,GN)和两条扫描线(G1',G2',……,G2N');N个单端转差分模块(101,102,……,10N)用于根据时钟信号,将N条信号输出线(G1,G2,……,GN)输出的扫描信号输出至2N条扫描线(G1',G2',……,G2N'),通过N条信号输出线(G1,G2,……,GN)对2N条扫描线(G1',G2',……,G2N')进行充电;其中,N≥1且N为正整数,可以减少驱动模块(201)的数量,有效降低显示装置的生产成本。
