Abstract:
(EN) Detection method and device for pixel charging compensation, and a pixel charging compensation method and device. The detection method comprises: 101 dividing a display region of a display panel into at least two compensation regions; 102 detecting a first brightness level of a target pixel in each of the compensation regions; 104 calculating, according to a difference value between the first brightness level and a preset brightness level obtained in step 103, a compensation period during which the target pixel is to be charged; and 105 setting the compensation period as a compensation period during which pixels in the compensation region in which the target pixel is located are to be charged.
(FR) L'invention concerne un procédé et un dispositif de détection de compensation de charge de pixel, et un procédé et un dispositif de compensation de charge de pixel. Le procédé de détection consiste : (101) à diviser une région d'affichage d'un panneau d'affichage en au moins deux régions de compensation ; (102) à détecter un premier niveau de luminosité d'un pixel cible dans chacune des régions de compensation ; (104) à calculer, selon une valeur de différence entre le premier niveau de luminosité et un niveau de luminosité prédéfini obtenu à l'étape (103), une période de compensation pendant laquelle doit être chargé le pixel cible ; et (105) à régler la période de compensation en tant que période de compensation pendant laquelle doivent être chargés des pixels de la région de compensation dans laquelle est situé le pixel cible.
(ZH) 像素充电补偿的检测方法及装置、像素充电的补偿方法及装置。检测方法包括:101将显示面板的显示区域划分至少两个补偿区域;102检测每个补偿区域中目标像素的第一亮度;103根据第一亮度与设定亮度之间的差值,104计算对该目标像素进行充电的补偿时间;105和将该补偿时间设定为该目标像素所在的补偿区域中像素进行充电的补偿时间。
