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.

Abstract: Disclosed is a method for manufacturing a liquid crystal display panel. The method includes two steps. In step 1, before being pressed together, the first substrate and the second substrate are provided therebetween with a first photo spacer having a relatively high height and a second photo spacer having a relatively low height, which is the same as a thickness of the liquid crystal layer. In step 2, after the first substrate and the second substrate are pressed together, the first photo spacer and the second photo spacer each have a thickness being the same as the thickness of the liquid crystal layer. The method is able to reduce the thickness of an air layer caused by the inconsistency between the height of the photo spacer and the thickness of the liquid crystal layer when a liquid crystal cell is formed, thereby improving the display quality of the liquid crystal device.
