Abstract

Embodiments of the present application provide a pixel driving control method, a driving control circuit, a display panel, and a storage medium. The pixel driving control method includes: generating a driving control signal according to the display data of the sub-pixels in the target column and the target display brightness; the driving control signal includes sub-driving control signals with at least two duty ratios; and controlling the output of the pixel driving circuit according to the driving control signal. The corresponding pixel driving signal; the pixel driving signal includes sub-driving signals of at least two duty ratios. In the embodiment of the present application, sub-pixels in different rows can be driven by signals with different duty ratios, and then the charging time of sub-pixels in different rows can be adjusted, so as to reduce the charging of sub-pixels in each row caused by the same charging time. difference, so that the display brightness of each row of sub-pixels tends to be consistent, thereby improving image quality and user experience.

Description

technical field [0001] The present application relates to the field of display technology, and in particular, the present application relates to a pixel driving control method, a driving control circuit, a display panel and a storage medium. Background technique [0002] The charging time of each row of pixels in the conventional driving method is the same, but for Z inversion, by figure 2 It can be seen that Z inversion (Z-Inversion or Z Dot Inversion) in a specific screen is prone to the charging difference between lines and horizontal stripes. [0003] TFT-LCD (Thin Film Transistor-Liquid Crystal Display, Thin Film Transistor-Liquid Crystal Display) will charge each pixel when it is working, so as to realize the display function of the pixel. In an ideal TFT-LCD driving model, the driving signal is symmetrically distributed based on the common electrode voltage Vcom, and the voltage of the display electrode is also symmetrically distributed based on Vcom, forming a fig...
