Embodiment Construction
[0041] A LED full-color screen system provided by a specific embodiment of the present invention is as follows: figure 2 As shown, it includes: control computer, video controller and LED display, and the control computer is connected with the LED display through the video controller. The LED display screen includes a plurality of LED display unit cabinets spliced together. Each LED display unit box includes: a scanning card and a plurality of LED display modules connected to the scanning card and working under the driving of the scanning card. Each LED display module includes an LED display module control unit and an LED lamp board (the LED display module control unit is usually a LED display module control card), and each LED display module communicates with its own LED display module control card. The scanning card connection of the LED display unit cabinet.
[0042] The difference from the prior art is that each LED display module is equipped with a brightness sensor, ...

The invention discloses a light-emitting diode (LED) full color screen system and a brightness adjusting method of the LED full color screen system. A brightness sensor is arranged on each LED display module of the LED display screen. The brightness adjusting method comprises the following steps of: acquiring an environmental brightness value of an environment where each LED display module is positioned; generating brightness adjustment data of each LED display module according to the environmental brightness value of the environment where each LED display module is positioned; and finally, adjusting the brightness of each LED display module according to the brightness adjustment data of each LED display module. For the LED full color screen system adopting the brightness adjustment method provided by the technical scheme, because the brightness sensor is arranged on each LED display module, the brightness of each LED display unit box body can be adjusted, the brightness of each LED display module even each pixel can be adjusted, and soft transition of bright and dark areas is realized; a blocking effect in the transition area is reduced, and a good visual effect is achieved; and meanwhile, light pollution in the environment is reduced, the power resources are saved, and the current low-carbon environment-friendly idea is met.
Description
technical field [0001] The invention relates to the technical field of LED display, in particular to an LED full-color screen system and a brightness adjustment method thereof. Background technique [0002] The current LED full-color screen 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] The environment in which the LED display is located may affect the display effect of the LED display. Usually, it is necessary to ...
