High color gamut, high brightness and high resolution 0.59″ SVGA liquid-crystal-on-Silicon (LCOS) panel is developed using novel color sequential technology. Design of frame-buffer-like pixels excludes the period of data addressing in the sub-frame and relaxes the design rules of the electric circuit and the LCOS panel. In addition, implementation of reset voltage makes the panel to achieve high performance at 360 Hz field rate. The color gamut is larger than 120% NTSC ratio and the reflectance is 70%.

A 0.38″ field-sequential-color liquid-crystal-on-Silicon (LCOS) microdisplay was developed for mobile projectors. An embedded sensor and heater was integrated onto the LCOS for ensuring a 90% NTSC color at a −20 °C ambient environment. Optical performance and reliability of this LCOS were characterized and discussed.
