Abstract

The invention discloses a semiconductor display panel driving interface configuration link and a method. A link between a time-sequence controller and a data driving circuit is configured according to identifier formats and content definition through configuration signaling, state signaling and correlative combination, the states of configuration devices are changed, and on the basis that the time-sequence controller and the data driving circuit are not redesigned, flexible switching of multiple connection modes such as end-to-end, one to two and one to multiple is achieved, so that specific requirements of different panels can be met.

Description

technical field [0001] The invention relates to the field of semiconductor display, in particular to the configuration and method of a display panel driving link. Background technique [0002] Now the driving principle of the liquid crystal display panel system is as follows: figure 1 shown. The timing controller is the action timing center of the entire display system. It cooperates with the frame display timing, sets the scan start, and serializes the interface input video signal, converts it into the data signal format required by the data drive circuit, and transmits it to the data drive circuit storage unit; the timing controller controls the scan drive circuit, Make it output appropriate switching voltages to specific scanning lines according to a certain order, so as to drive the scanning lines. The data driving circuit is turned on in conjunction with the specific scanning line, and converts the digital video signal into a voltage to be output to the pixel electro...
