Abstract

The embodiment of the invention discloses a plugging assembly comprising a first plugging element and a second plugging element arranged in pair. The first plugging element consists of a multi-path data set output pin group, a power supply pin group, and a ground pin group; and the second plugging element includes a multi-group data set output pin group, a display control signal output pin group, a multi-path ethernet interface pin group and a ground pin group. In addition, the embodiment of the invention also discloses a display screen control card including the plugging assembly and a display screen system.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a plug assembly, a display screen control card and a display screen system. Background technique [0002] In the existing LED display system, the video source sends the video signal to the sending card through the video interface, and then the sending card is responsible for converting the video signal into a digital signal and distributing the digital signal, outputting it from multiple output interfaces to connect with it Each receiving card in different LED cabinets. Since the receiving card itself stores the parameters of the LED cabinet where it is located, after receiving the display data, the receiving card will correspondingly reverse the received data according to the wiring mode of the light board driver chip carried by itself, and then generate The RGB data group is transmitted to the data input terminal of the light board driver chip; while the light board driver ch...
