Splicing display apparatus control system

Abstract

The invention discloses a splicing display apparatus control system. The system comprises a controller unit, a first electric power network bridging module, and second electric power network bridging modules respectively connected with the display units of a splicing display apparatus, wherein the controller unit is connected with a power line through the first electric power network bridging module; the display units are connected with the power line through the second electric power network bridging modules; the controller unit outputs a control signal to the first electric power network bridging module according to control operation, and the first electric power network bridging module loads the control signal to the power line; and the second electric power network bridging modules obtain the control signal from the power line and sends the control signal to corresponding display units. According to the invention, the display units are connected with the power line through the first electric power network bridging module so as to be connected to an electric power network so that a large quantity of wire rods is saved, there are links for mutual communication among the forgoing parts, and intelligent brightness adjustment can be realized according to the background light mode determined by the controller unit.

Description

technical field [0001] The present invention relates to the technical field of splicing display, in particular to a control system of a splicing display device. Background technique [0002] The traditional splicing display device control system is based on LAN and RS485 industrial network. Each display unit of the splicing display device has a serial interface or network cable interface and at least one video input port such as DVI interface. The serial interface communicates and controls the display unit, and the processor connects to the video input port through the video cable to transmit the content of the image signal generated by the corresponding display unit. [0003] Peripheral devices such as dimming lights are far away from the control computer, and the control computer generally needs to convert serial port signals into RS485 differential signals for transmission to peripheral devices. Therefore, in addition to power lines for connection, this splicing display ...
