Title:
INITIAL SIGNAL GENERATOR, DISPLAY PANEL AND DISPLAY METHOD THEREOF, AND DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/045067
Kind Code:
A1
Abstract:
A display panel and a display method thereof, and a display device. The display panel comprises a plurality of pixel units, which are arranged in an array, wherein the pixel units each comprise a plurality of sub-pixels, the sub-pixels each comprising a pixel driving circuit and a light-emitting element, which is connected to the pixel driving circuit. The display panel further comprises an initial signal generator, and comprises a low-frequency driving mode and a normal driving mode, wherein the low-frequency driving mode comprises a refresh frame stage, in which data is written into the pixel units, and a maintenance frame stage, in which the data written into the pixel units is maintained; and the initial signal generator is configured to: acquire, in the low-frequency driving mode, the current display brightness segment and a picture to be displayed; quantize said picture to obtain an average grayscale proportion; determine corresponding anode reset voltages according to the current display brightness segment and the average grayscale proportion; and output, in the maintenance frame stage, the corresponding anode reset voltages to the pixel driving circuits, so as to reset anodes of the light-emitting elements.
