Abstract

A LCD comprises a panel and drive circuit. The drive circuit comprises a signal generation device, an interface circuit and a LCD drive. The interface circuit comprises several system control paths, several image control paths, several data transmission liens and an interface selection path. The signal generation device generates several data signal, several system control signal, several image control system and an interface selecting signal. The system control path, image control path and data transmission path are used to transmit the system control signal, image control signal and the data signal to the LCD drive. The interface selection path is used to connect the system control path and the image control path.
