Problems solved by technology

This method has the following disadvantages: the backlight value of the display device is obtained according to the mapping relationship, and the backlight value is directly written to the display device, resulting in a fast and unstable backlight adjustment process, which will cause the display screen to flicker, thereby causing the display device to output a flickering screen. The display effect of the display screen is poor

Abstract

The invention discloses a dynamic backlight adjustment method, comprising following steps: valuing a target backlight value of a display device at the beginning of a current judgment period according to a display picture status of the display device in a previous judgment period; reading display picture brightness of the display device according to a preset reading period; calculating a final backlight value after each reading of the display picture brightness; adjusting a backlight value of the display device according to the final backlight value obtained by each calculation. The invention also discloses a dynamic backlight adjustment device. By using embodiments of the invention, a backlight adjustment process of the display device may be slowed and stabilized, and disturbances of input signal fluctuation upon the display device backlight adjustment process can also be avoided, thus effectively avoiding display picture scintillation. The invention also gives a consideration on user experience, improving user operability of backlight adjustment.

Description

technical field [0001] The invention relates to the field of liquid crystal display equipment, in particular to a dynamic backlight adjustment method and a dynamic backlight adjustment device. Background technique [0002] Existing liquid crystal display devices mostly adopt dynamic backlight adjustment technology to achieve the purpose of energy saving. Most of the traditional dynamic backlight adjustment methods are to obtain the backlight value of the display device according to the mapping relationship between the brightness of the display screen of the display device and the backlight value, and then directly write the corresponding backlight value to the display device for backlight adjustment. This method has the following disadvantages: obtain the backlight value of the display device according to the mapping relationship, and directly write the backlight value to the display device, resulting in a fast and unstable backlight adjustment process, causing the display s...
