Abstract

The invention discloses an LED display screen brightness adjusting method and system, and relates to the technical field of LED display, and the system greatly improves the accuracy of a display effect through an accurate brightness data acquisition, processing and adjusting mechanism. The brightness data acquisition module monitors the ambient light intensity and the current brightness of the LED display screen in real time, which provides a basis for subsequent data processing and brightness adjustment. And the data preprocessing module corrects and filters the data, so that the accuracy and reliability of the data are ensured. And the brightness adjustment algorithm module calculates target brightness Ltarget according to the accurate data, calculates actual brightness Lactual through dynamic adjustment, and outputs nonlinear adjustment brightness LadJust in combination with color temperature change and nonlinear response of the display screen. The accurate adjustment capability ensures that the brightness of the display screen is always suitable under different illumination conditions, and the situation that the brightness is too strong or too weak is avoided.
