Abrégé
(EN) A display panel (10) and a driving method therefor. Pixel electrodes of the display panel (10) are divided into multiple groups according to the color of penetrable light. That is, each group of pixel electrodes allows penetration of light having the same color. In a display process of a frame of picture, a data driver (12) applies an independent Gamma voltage to each group of pixel electrodes, and a gate driver (11) sequentially drives gate lines connected to one group of pixel electrodes and then sequentially drives gate lines connected to a subsequent group of pixel electrodes, such that the Gamma voltages applied to pixels having different colors can be independently adjusted.
(FR) L’invention concerne un panneau d’affichage (10) et un procédé d'attaque associé. Des électrodes de pixels du panneau d'affichage (10) sont divisées en groupes multiples en fonction de la couleur de la lumière pouvant pénétrer. C'est-à-dire que chaque groupe d'électrodes de pixels permet une pénétration de lumière ayant la même couleur. Lors d'un traitement d'affichage d'une trame d'image, un pilote de données (12) applique une tension gamma indépendante à chaque groupe d'électrodes de pixels, et un circuit d'attaque de grille (11) attaque séquentiellement des lignes de grille connectées à un groupe d'électrodes de pixels et attaque séquentiellement ensuite des lignes de grille connectées à un groupe suivant d'électrodes de pixels, de sorte que les tensions gamma appliquées à des pixels ayant des couleurs différentes puissent être réglées indépendamment.
(ZH) 一种显示面板（10）及其驱动方法，根据允许透过的光的颜色将显示面板（10）的像素电极划分为多组，即每组像素电极允许相同颜色的光透过，并在一帧画面的显示过程中，由数据驱动器（12）对每组像素电极施加独立的Gamma电压，由栅极驱动器（11）依次驱动与一组像素电极连接的栅极线之后，再依次驱动与下一组像素电极连接的栅极线，从而能够独立调整施加至不同颜色的像素的Gamma电压。
