Abstract

The invention provides an automatic brightness adjusting method for an LED display screen. The automatic brightness adjusting method comprises the following steps that a sampling speed is set, and the light brightness of a current environment is regularly detected; the light brightness of the environment is converted into a corresponding display screen brightness target value; whether the display screen brightness target value is larger than a minimum display screen brightness value stored in a controller or not is judged, if yes, the controller adjusts the brightness value towards the target value step by step according to the brightness adjusting sensitivity stored in the controller based on the current display screen brightness value until the display screen brightness reaches the target value, and it not, the display screen brightness target value is set to be the minimum display screen brightness value stored in the controller and then adjusted towards the target value step by step until the display screen brightness reaches the target value. The automatic brightness adjusting method is capable of automatically adjusting brightness, carrying out adjustment stage by stage and saving more energy, convenient to implement and user friendly.

Description

technical field [0001] The invention belongs to the technical field of HDMI signals, and in particular relates to an automatic brightness adjustment method of an LED display screen. Background technique [0002] At present, there are basically three methods of LED display adjustment: manual adjustment, timing adjustment and automatic adjustment. The first two adjustment methods do not require environmental monitoring equipment, while automatic adjustment requires environmental monitoring equipment. Mainstream, manual adjustment is the user manually adjusts according to the ambient brightness, which requires personnel maintenance. Timing adjustment is to adjust the brightness according to the set time period. During the day, the display screen can be adjusted to be slightly brighter, and at night, it can be adjusted to be slightly darker, but it cannot solve the change of ambient brightness with the weather. [0003] In the entire brightness adjustment of the display screen,...
