Title
(EN) Display panel, pixel charging method and computer readable storage medium
(ZH) 显示面板、像素充电方法和计算机可读存储介质
Abstract
(EN)
The invention discloses a pixel charging method, which comprises the following steps: when the opening of a first grid integrated circuit on a thin film transistor substrate is detected, obtaining a preset charging time duration and a 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 circuitexcept the first grid integrated circuit on the 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 the thin film transistor switches in the pre-charging time period and the actual charging time period correspondingto the scanning lines so as to charge pixels corresponding to the scanning lines, wherein, the voltage polarity of each pixel electrode corresponding to a data line on the thin film transistor substrate is the same. The invention further discloses a display panel and a readable storage medium. The display panel, pixel charging method and the computer readable storage medium ensure the overall brightness uniformity of the display panel.
