Patent number: 6747626Abstract: The present invention relates to a source driver circuit (200) for driving a thin film transistor liquid crystal display (TFT-LCD) panel. The source driver circuit (200) provides several different operating modes for the driver to lower the power consumption of a TFT-LCD module while still providing a wide analog voltage range to the liquid crystal display elements. A mode signal (MODE) switches the driver from gray scale to standby mode wherein the internal resistive digital to analog converter (202), decoder/output voltage drivers (210) and output buffer amplifiers (212) are powered down. In addition, only the most significant bit of data corresponding to red, green and blue are transferred to a sample and hold register (206, 208). Output cells (216), substituting for the decoder/output voltage drivers, receive one-bit data from hold registers (208) and provide voltage at the output of the driver circuit (200).Type: GrantFiled: November 27, 2001Date of Patent: June 8, 2004Assignee: Texas Instruments IncorporatedInventor: Johnson Chiang
