Title (EN) DISPLAY DEVICE AND DRIVE METHOD THEREFOR
(FR) DISPOSITIF D'AFFICHAGE ET PROCÉDÉ D'ATTAQUE ASSOCIÉ
(ZH) 显示装置及其驱动方法
Abstract:
(EN) A display device and a drive method, the display device comprises: multiple pixels, data signal lines (104) that provide data signals to the multiple pixels; scan signal lines (105) arranged to intersect the data signal lines (104); and a driver circuit (300) that outputs a scan signal to the scan signal lines (105) so as to actuate the scan signal lines (105); the driver circuit (300) outputs a voltage having a waveform that has a voltage level change cycle, where the voltage level of the waveform of the scan signal drops at a slope of a pre-configured value, such that when the waveform of the scan signal drops, the waveform has a portion that changes at the slope of the pre-configured value in the range between the high voltage level and the low voltage level, thereby enhancing the display quality of the display device.
(FR) L'invention concerne un dispositif d'affichage et un procédé d'attaque, ce dispositif d'affichage comprenant : de multiples pixels, des lignes de signaux de données (104) qui fournissent des signaux de données aux multiples pixels ; des lignes de signaux de balayage (105) agencées pour couper les lignes de signaux de données (104) ; et un circuit d'attaque (300) qui délivre un signal de balayage aux lignes de signaux de balayage (105) de façon à actionner les lignes de signaux de balayage (105) ; le circuit d'attaque (300) délivre une tension dont la forme d'onde comprend un cycle de changement de niveau de tension, le niveau de tension de la forme d'onde du signal de balayage chutant selon une pente d'une valeur prédéfinie, de telle sorte que, lorsque la forme d'onde du signal de balayage chute, la forme d'onde présente une partie qui change, selon la pente de la valeur pré-configurée, dans la plage se situant entre le niveau élevé de tension et le niveau bas de tension, ce qui permet d'améliorer la qualité d'affichage du dispositif d'affichage.
(ZH) 一种显示装置及其驱动方法,显示装置包括:多个像素;向多个像素提供数据信号的数据信号线(104);设置为与数据信号线(104)相交的扫描信号线(105);以及向扫描信号线(105)输出扫描信号以致动扫描信号线(105)的驱动电路(300),驱动电路(300)输出包括具有电压电平变化周期的波形的电压,其中扫描信号的波形的电压电平以预定数值的斜率方式下降,使扫描信号的波形于下降时的高电压电平和低电压电平之间的范围内有以预定数值的斜率变化的部分,从而提升显示装置的显示质量。
