LED display screen control system

Abstract

The invention relates to an LED display screen control system. The LED display screen control system comprises an upper computer, a system front end, a system rear end and an LED display screen which is connected with the system rear end. The system front end is connected with the system rear end by a power line, data signals transmitted by the upper computer are converted into carrier signals by the system front end which transmits the data signals and the carrier signals to the system rear end by the power line, and the system rear end transmits the processed signals to the LED display screen and drives the LED display screen to display output. The system front end converts the data signals of the upper computer into the carrier signals by the carrier communication technology, transmits the carrier signals to the system rear end and the LED display screen by the power line and simultaneously supplies power to the LED display screen; and only the power line is arranged between the system rear end and the system front end for connecting communication and other communication interfaces are unnecessary, thus simplifying structural design, reducing connectors and signal lines, and improving product safety and stability.

Description

Technical field [0001] The invention relates to a display screen control system, in particular to an LED display screen control system. Background technique [0002] The existing LED display control system generally includes a host computer, a main controller, and an LED display. The LED display screen obtains data signals such as video signals from the host computer through data lines. At the same time, the LED display screen needs to be equipped with a power line to draw power from an external three-phase AC power supply. The host computer can be different interface devices. If the LED display screen needs to obtain video signals from different host computers, multiple different communication interfaces and connectors need to be set on the LED display screen. As a result, the existing LED display screen has more signal lines and requires more connectors, resulting in a more complex structural design. Problems with any connector will cause the display effect of the entire ...

AI Technical Summary

Problems solved by technology

The LED display shows that the LED display of the control system transmits data signals with the upper computer through the network cable. Too many transmission lines and power lines make the installation and connection process complicated and huge. At the same time, due to too many data transmission lines, power lines and connectors, the stability of data signal transmission will be greatly affected, which will affect the display and use of LED displays.
