Abstract

The invention discloses an LED rental screen system and a brightness correction method thereof. Each LED display module of the LED display screen is provided with a timer for recording and feeding back the accumulative working time of the LED display module to the control computer. The brightness correction method first obtains the cumulative working time of each LED display module; then calculates the brightness attenuation value of each module according to the cumulative working time; then generates brightness correction data according to the brightness attenuation value; finally corrects the display of each module according to the brightness correction data brightness. A LED rental screen system adopting the brightness correction method of the LED rental screen system according to the technical solution of the present invention, since each LED display module is provided with a timer, the control computer can obtain the cumulative work of each LED display module Time, so as to correct the brightness accordingly, to avoid the phenomenon that the newer modules or cabinets display brighter overall, while the longer-used modules or cabinets display darker overall, so as to ensure that the LED display can have better display effect.

Description

technical field [0001] The invention relates to the technical field of LED display, in particular to an LED rental screen system and a brightness correction method thereof. Background technique [0002] The current LED display system usually includes: a control computer, a video controller and an LED display, and the LED display usually includes a plurality of LED display unit cabinets assembled together. Control the video files in the computer and transmit them to a certain LED display unit box of the LED display through the video controller. Each LED display unit box intercepts its own part of the image file for display, and at the same time transmits the image file to the next LED display unit box. The combination of the contents displayed by each LED display unit box is the picture that the LED display should display. [0003] Because the current LED display system is relatively expensive, and if a special LED display system is set up in many occasions, the utilization...
