Abstract

The invention belongs to the technical field of image signal generation, and discloses a long-distance distributed graphic signal generator based on optical fiber, comprising a main signal card, an optical fiber, and a signal interface card. The test file is converted into video information and configuration command information, and the information is encoded and packaged and sent to the signal interface card through the optical fiber; the signal interface card is used to decode the received information, and output the corresponding module interface under the control of the configuration command information. video information. The invention solves the problem of serious signal attenuation caused by cable routing in the generation of graphic signals in the prior art.

Description

technical field [0001] The invention relates to the technical field of image signal generation, in particular to an optical fiber-based long-distance distributed image signal generator. Background technique [0002] In the various links of R&D, production and testing of large-size LCD panels, LCD module manufacturers, due to the large size of the panel, the signal wiring is too long, and the traditional cable wiring leads to serious signal attenuation and poor anti-interference ability. The development and testing of modules brings great difficulties. Contents of the invention [0003] The embodiment of the present application provides a long-distance distributed graphic signal generator based on an optical fiber, which solves the problem in the prior art that the graphic signal is generated by using cables to cause serious signal attenuation. [0004] An embodiment of the present application provides an optical fiber-based long-distance distributed graphic signal generat...
