In this paper, we propose the hardware architecture of a scale converter which is to convert a variety range of scale into a target scale and a time sequential color control driver for LOCS (Liquid Crystal On Silicon) micro display devices which are considered advanced micro display technology in the next generation. The driver has been implemented and tested with ASIC chips.

This paper presents an implementation of a calibration circuit to correct the gain error, DC offset and sampling clock phase error generated in the process of converting digital pixels to analog pixels to drive an analog-driven 4K UHD LCOS panel. The proposed calibration circuit consists of a gain and DC offset adjustment circuit and a sampling clock phase adjustment circuit. The calibration circuit is implemented with an FPGA device, and video amplifiers.
