LED (Light Emitting Diode) display screen system

Abstract

The invention discloses an LED (Light Emitting Diode) display screen system and belongs to the technical field of display screens. The system comprises an upper computer, a sending control card and an LED screen main body, wherein the LED screen main body comprises a plurality of LED box bodies which are arrayed in a matrix; each LED box body comprises a plurality of receiving cards and a plurality of LED modules which are arrayed in a matrix; each LED module comprises a current-limiting protection block; the upper computer is electrically connected with each LED module through the sending control card and the plurality of receiving cards of each LED box body. According to the display screen system disclosed by the invention, module-grade current-limiting protection can be realized and hidden dangers of heating, fire and the like, caused by large current, are extremely reduced.

Description

technical field [0001] The invention relates to the technical field of display screens, in particular to an LED display screen system. Background technique [0002] The LED display system plays an important role in today's information age. However, during the long-term use of the existing LED display system, various abnormal phenomena sometimes appear, such as playing computer blue screen, single box Stuck, chip sluggishness on the unit board, etc. These abnormal phenomena can be restored to normal through the action of power-on reset. At this time, based on the design of the existing LED display system, the general method is to dispatch The staff went to the scene to turn off the power input and perform a hard restart to solve this problem. In this way, not only will it cost a lot of manpower and material resources, but also it is easy to have a large area of ​​black screen and cause a large display output. In addition, due to the lack of an effective current-limiting prot...

In this way, not only will it cost a lot of manpower and material resources, but also it is easy to have a large area of ​​black screen and cause a large display output.

In addition, due to the lack of an effective current-limiting protection mechanism in the existing LED display system, during the long-term use of the display, sometimes the current is too large to cause the display to heat up, and even cause a fire on the display, which brings serious problems to people. human and financial losses
