Multi-interface video processing circuit

The invention discloses a multi-interface video processing circuit, comprising a multi-interface element, a time-sequence controller and a buffer. The time-sequence controller can sort and transmit a low-voltage differential signal, a low-magnitude swaying differential signal or a transistor-transistor logic signal to the multi-interface element. The multi-interface element can be suitable for sending out different types of signals to a source-electrode drive in virtue of the arrangement of the buffer. Adopting the invention can lead a video processing circuit to provide different types of signals to different source-electrode drives provided with the same hardware. Designers can change the arrangement of the buffer to lead the video processing circuit to provide different signals to the source-electrode drive without changing the design of the circuit, and then the invention can reduce time and cost spent on designing and manufacturing.
