Title:
BACKLIGHT BRIGHTNESS CONTROL METHOD AND APPARATUS, TERMINAL DEVICE, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2024/077609
Kind Code:
A1
Abstract:
A backlight brightness control method and apparatus, an electronic device, and a storage medium. The method comprises: (201) for a time interval between the last time a frame synchronization signal is received and the time when a backlight compensation coefficient is calculated, calculating a frame refresh rate of a display device in the time interval; (202) acquiring an image frame to be displayed, and determining a pixel signal feature of said image frame; (203) on the basis of the frame refresh rate, the pixel signal feature, and backlight setting parameters of the display device, calculating the backlight compensation coefficient corresponding to said image frame; and (204) on the basis of the backlight compensation coefficient, controlling backlight brightness when said image frame is displayed on the display device, wherein the backlight compensation coefficient is calculated on the basis of the real-time frame refresh rate, the pixel signal feature and the backlight setting parameters. The backlight brightness of the display device can be compensated in real time, so that the display device can have a stable brightness presentation, and the visual experience of the user is improved.
