Abstract

An embodiment of the invention discloses a display screen control system. A data converter is arranged between a data transmitting end and a data receiving end to convert network port data into optical fiber data to perform data transmission, thereby solving the technical problems of numerous network cables and complicated field cable connection. In addition, an embodiment of the invention discloses a display controller integrating a network port / optical fiber converter.

Description

technical field [0001] The present invention relates to the technical field of display control, in particular to a display screen control system and a display controller. Background technique [0002] The connection between the sending card and the receiving card in the LED display control system generally uses a network cable. At present, the loading capacity of ordinary sending cards is 1080P, which requires four network cables for transmission. When loading a super large LED display, more network cables are required. Taking a 4K*2K resolution LED display as an example, 16 network cables need to be connected between the sending card and the receiving card. If a backup module is used for on-site reliability , then 32 network cables are needed, so it can be imagined that there are so many network cable connections between the sending card and the receiving card, and the field wiring will be quite troublesome. Therefore, in the process of realizing the present invention, th...
