Abstract

The invention provides a screen backlight frequency adjustment method, device and apparatus and a storage medium. For a display screen with a variable refresh rate, the current refresh rate of the display screen in a variable refresh rate mode is obtained in real time, a backlight frequency target value of the display screen without water ripples is determined according to the current refresh rate, and the current backlight frequency of the display screen is adjusted according to the backlight frequency target value, so that water ripples on the display screen can be avoided, and the display quality of the display screen is improved.

Description

technical field [0001] The present application relates to the technical field of liquid crystal display, and in particular to a screen backlight frequency adjustment method, device, equipment and storage medium. Background technique [0002] The refresh frequency of the LCD screen refers to the vertical scanning frequency of the screen, that is, the number of images that the screen can display per second, and the backlight frequency is the adjustment frequency of the backlight PWM signal of the light-emitting diode in the LCD screen. Due to the overlapping of the refresh frequency and the backlight frequency, water ripples will appear on the display screen, which will affect the display quality. [0003] In the prior art, for a screen with a fixed refresh rate, during the debugging process, the backlight frequency is usually adjusted according to the refresh rate of the screen, that is, the frequency corresponding to the fixed refresh rate and the water ripple phenomenon is ...
