Abstract

The invention discloses an LED rental screen system and a brightness correction method thereof. Each LED display module of an LED display screen is provided with a timer which is used for recording and which feeds accumulative operating time of the LED display module with the timer back to a control computer. The brightness correction method includes: acquiring accumulative operating time of each LED display module; calculating brightness attenuation value of each module according to the accumulative operating time; producing brightness correction data according to the brightness attenuation value; correcting display brightness of each module according to the brightness correction data. In the LED rental screen system, each LED display module is provided with one timer, and the control computer can acquire accumulative operating times of the LED display modules so as to correct brightness according to the accumulative operating times; the problem of overall brightness of new modules or a box is high while overall brightness of long-used modules or the box is low is avoided; accordingly, the LED display can display better.

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...
