Abstract

The present application provides a method for determining a target charging time, a charging method, a device, and a display device. The method for determining the target charging time includes: the target charging time is the target charging time of any pixel set in the display panel, and the method includes: determining the ideal charging time of each pixel unit in several pixel units of each pixel set; displaying The pixels of the panel are divided into several pixel sets, and each pixel set includes several pixel units; from the ideal charging time of each pixel unit in each pixel set, the maximum ideal charging time is determined as the target charging time of the pixel set, and Target charge time for each pixel set. The present application realizes that each pixel set of the display panel can obtain a personalized charging time, and there is no mutual restriction of the charging time among the pixel sets, which can improve the charging accuracy of the display panel, thereby ensuring the display quality of the display panel.

Description

technical field [0001] The present application relates to the field of display technology, and in particular, the present application relates to a method for determining a target charging time, a charging method, a device, and a display device. Background technique [0002] The display panel includes a plurality of pixel units distributed in an array, and the driving device of each pixel unit usually includes an energy storage element, such as a capacitor. In order to make the display panel work normally, it is usually necessary to charge each pixel unit. [0003] The existing charging method of the display panel is: charging all the pixel units of the display panel with a given charging time. However, there are differences in the characteristics of the driving device of each pixel unit, such as different threshold voltages, NBTS (Negative Bias Temperature Stress, negative bias temperature characteristics, used to characterize the quality of TFT characteristics, ideally aro...
