A signal processing part receives 10-bit pixel data through a horizontal signal line, performs predetermined signal processing, and passes parallel-format data to a switching part.

The output buffer externally outputs differential output of normal video data and inverted video data individually from output terminals. Accordingly, the problems in power consumption, noises, and unnecessary radiation are solved, and higher-speed output is achieved.
