Abstract
(EN)
A pixel charging method, a display panel, and a computer readable storage medium. The pixel charging method comprises: when a first grid integrated circuit is turned on, obtaining a preset charging time duration and the current time point; determining a pre-charging time period and an actual charging time period of a scanning line corresponding to each target grid integrated circuit on a thin film transistor substrate according to the preset charging time duration and the current time point; controlling a thin film transistor switch corresponding to the scanning line of each target grid integrated circuit, and opening same in the pre-charging time period and the actual charging time period corresponding to the scanning line so as to charge a pixel, thereby solving the problem of uneven brightness and low image quality of the display panel caused by insufficient charging.
(FR)
L'invention concerne un procédé de charge de pixel, un panneau d'affichage et un support de stockage lisible par ordinateur. Le procédé de charge de pixel consiste : lorsqu'un premier circuit intégré de grille est allumé, à obtenir une durée de charge prédéfinie et l'instant actuel ; à déterminer une période de précharge et une période de charge réelle d'une ligne de balayage correspondant à chaque circuit intégré de grille cible sur un substrat de transistor à couches minces en fonction de la durée de charge prédéfinie et de l'instant actuel ; à commander un commutateur à transistor à couches minces correspondant à la ligne de balayage de chaque circuit intégré de grille cible, et à l'ouvrir dans la période de précharge et la période de charge réelle correspondant à la ligne de balayage de façon à charger un pixel, ce qui permet de résoudre le problème de luminosité irrégulière et de mauvaise qualité d'image du panneau d'affichage provoqué par une charge insuffisante.
(ZH)
一种像素充电方法,显示面板和计算机可读存储介质,其中像素充电方法包括:在第一颗栅极集成电路打开时,获取预设充电时长以及当前时间点;根据预设充电时长以及当前时间点,确定薄膜晶体管基板各个目标栅极集成电路控制的扫描线的预充时间段与实际充电时间段;控制各个目标栅极集成电路的扫描线对应的薄膜晶体管开关,在扫描线的预充时间段以及实际充电时间段打开,以对像素进行充电,从而解决充电不足引起的显示面板整体亮度不均、画面品质低下的问题。
