Abstract

The invention relates to an LED display screen system, a data distributor, and a display control method. The LED display screen system comprises a plurality of strings of LED display unit plates, and a data distributor. Every string of LED display unit plates comprises an LED display unit plate body or a plurality of cascaded LED display unit plates, and every LED display unit plate comprises an LED lamp panel and a scanning card module fixedly disposed on the LED lamp panel. The scanning card module comprises a programmable logic device. The data distributor is connected with the plurality of strings of LED display unit plates, and is used to transmit the display data, which can be acquired from the front end by the network interface or the optical port, respectively to the plurality of strings of LED display unit plates after the data segmentation. By additionally providing the data distributor, the unvarnished transmission of the front end data, for example, the transmitting card data, and the segmentation and the forwarding from the transmitting card data to the scanning card data can be completed, and therefore the loading problem of the prior art after the integration of the scanning card and the LED lamp panel can be effectively solved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an LED display screen system, a data distributor and a display control method. Background technique [0002] In the existing LED display system, it mainly includes video source, sending card, scanning card and LED display. The LED display is spliced ​​by a plurality of LED cabinets, and each LED Light panels spliced ​​together. [0003] figure 1 It shows the architecture of a current LED display system, which mainly includes a sending card, a scanning card and an LED light board, wherein the scanning card and the LED light board, and the LED light board and the LED light board are connected by cables. In the current system structure, due to the connection between the scanning card and the LED light board, and between the LED light board and the LED light board, a large number of cable connections cause the instability of signal transmission and bring troubles to the installati...
