Abstract: A display drive circuit is provided, including a line buffer, a lever converter, a D/A converter, a Gamma reference voltage generator, and a buffer. The Gamma reference voltage generator has a first duty time and second duty time. In the first duty time, the Gamma reference voltage generator outputs the Gamma voltage to the buffer to charge pixel electrodes of a display having the display drive circuit. In the second duty time, the Gamma reference voltage generator outputs a common voltage to the buffer.
