Adjustable gamma correction reference voltage source for LCoS
In this paper, an adjustable gamma correction reference voltage source for Liquid Crystal on Silicon (LCoS) is proposed. The reference voltage source is taped out by Chartered 0.35µm CMOS 2P4M Mixed-mode process, and the chip was tested. The test results indicate that the output of the chip can completely meet requirements of the common electronic field-inversion field sequential LCoS display system, and the setup time and accuracy of output voltage achieve the expected target.
