A compact silicon microdisplay for virtual reality applications

We have developed a highly integrated liquid-crystal-on-silicon microdisplay for virtual reality applications. The silicon panel of 704/spl times/576 spatial resolution was designed and fabricated by a custom 0.35 /spl mu/m CMOS technology. The pixel pitch was 9.6 /spl mu/m and the fill factor was 88%. A three-dimensional (3D) video stream in an interlaced format was generated by a 3D modeling code for test and demonstration. A color sequential technique and control logic was implemented to obtain full color and extract video frames for the display. With two silicon microdisplays and eyepieces for each eye, we have demonstrated a 3D stereoscopic display.
