Abstract

The invention relates to a control system of an LED display screen and a control circuit board thereof. A slave control circuit board is provided with a signal input / output interface, a receiving chipand a board-to-board plug connector; and the receiving chip is connected with the signal input interface, the board-to-board plug connector and the signal output interface, and is used for identifying the display data, sending the identified display data to the board-to-board plug connector and sending the display data to the signal output interface. According to the control system of the LED display screen and the slave control circuit board of the control circuit board of the LED display screen, the receiving chip is adopted, a receiving card and a sending card are not needed, the size is reduced, and the production cost and the maintenance cost are reduced.

Description

technical field [0001] The invention belongs to the technical field of LED display screens, in particular to a control system of LED display screens and a control circuit board thereof. Background technique [0002] LED display has the advantages of high brightness, low operating voltage, low power consumption and long life, and has been widely used. In order to meet the needs of different scenarios, various types of LED displays have emerged. For example, a strip display is a relatively common LED display. The strip display screen is usually installed on a supermarket display stand, a shelf or a door and used as a label. It is a strip display screen composed of a plurality of display modules connected end to end and fixed together. [0003] The defective of prior art scheme: [0004] 1. The control circuit board of each display module needs to be equipped with a receiving card and a sending card, and the production and maintenance costs are relatively high; [0005] 2. W...
