The invention is applicable to the technical field of computers, and provides a brightness equalization method and device of an LED display screen, an LED display apparatus and a storage medium. The method comprises the steps of obtaining the LED lamp strip parameter information of a to-be-adjusted display subarea of the LED display screen and a current environment brightness value; calculating the brightness balance coefficient of each LED lamp contained in the LED lamp strip of the display subarea to be adjusted according to the LED lamp strip parameter information and the current ambient brightness value; and adjusting the output power of each LED lamp according to the brightness equalization coefficient of each LED lamp, so that the brightness of the LED display screen is equalized. The brightness balance coefficient of each LED lamp contained in the LED lamp strip of the display subarea to be adjusted is calculated mainly according to the parameter information of the LED lamp strip and the current ambient brightness value, and the output power of the LED lamp is adjusted according to the calculated brightness balance coefficient, so that the implementation process is simple, the cost is low, and the universality is flexible.
Description
technical field [0001] The invention belongs to the technical field of computers, and in particular relates to a method and device for equalizing brightness of an LED display screen, an LED display device and a storage medium. Background technique [0002] Due to its own advantages, such as low working voltage, it can actively emit light and have a certain brightness, and can adjust the brightness through voltage (or current). Has been widely used. However, LED screens usually have unbalanced display brightness during use, which seriously affects the display effect of the LED screen. The research shows that the reason for the uneven display brightness of the LED screen is that during the rotation of the LED strip, the linear speeds corresponding to the LED lights at different positions are different, which affects the brightness of some LED lights. [0003] At present, in order to solve the problem of uneven display brightness of the LED screen, when making LED display vid...
