Title

(EN) DISPLAY DEVICE AND DRIVING METHOD THEREFOR

(FR) DISPOSITIF D'AFFICHAGE ET PROCÉDÉ D'ATTAQUE S'Y RAPPORTANT

(ZH) 显示装置及其驱动方法

Abstract

(EN) A driving method for a display device. The display device (1000) comprises a backlight module (200) and a display panel (100). The display panel (100) comprises a gate driving circuit (103) and a data writing transistor (T1). The gate driving circuit (103) is configured to transmit a scanning signal to the data writing transistor (T1). The driving method comprises: when the display device (1000) performs display at different refresh rates, the voltage values of the scanning signals output by the gate driving circuit (103) are different, and/or the average light-emitting brightnesses of the backlight module (200) are different.

(FR) L'invention concerne un procédé d'attaque pour un dispositif d'affichage. Le dispositif d'affichage (1000) comprend un module de rétroéclairage (200) et un écran d'affichage (100). L'écran d'affichage (100) comprend un circuit d'attaque de grille (103) et un transistor d'écriture de données (T1). Le circuit d'attaque de grille (103) est configuré pour transmettre un signal de balayage au transistor d'écriture de données (T1). Le procédé d'attaque comprend les étapes suivantes : lorsque le dispositif d'affichage (1000) effectue un affichage à différentes fréquences de rafraîchissement, les valeurs de tension des signaux de balayage délivrés par le circuit d'attaque de grille (103) sont différentes, et/ou les luminosités d'émission de lumière moyennes du module de rétroéclairage (200) sont différentes.

(ZH) 一种显示装置的驱动方法。显示装置（1000）包括背光模组（200）和显示面板（100），显示面板（100）包括栅极驱动电路（103）和数据写入晶体管（T1），栅极驱动电路（103）被配置向数据写入晶体管（T1）传输扫描信号。驱动方法包括：在显示装置（1000）以不同的刷新频率进行显示的情况下，栅极驱动电路（103）输出的扫描信号的电压值不同，和/或，背光模组（200）的平均发光亮度不同。
