| Abstract: | The standard of DVI interface as a new generation digital display technology communication standard,transmission in the channel as fully digital code stream. This paper proposed a digital video transmission to digital display solutions based on the research of the DVI interface application system. By analyzing the DVI application design methods related DDC and EDID, this paper introduces a digital video interface system of DVI basic structure and principles;this interface system apply in 16 x32 pixels full color LED display system, can decode data stream of computer, RGB data can be correctly transmitted to LED and displaying real-time. After the test, system runs stably. |
