Color Head Down Display Program
Abstract
The purpose of the CHDD program was to develop a large-area AMLCD for cockpit applications. A 4- x 8-in. polysilicon AMLCD with 320,000 display cells was designed with integrated scanners and fabricated. A support electronics system was constructed that accepted multisource RGB video. This system reformatted the video information to drive the display at 180 fields/second and synchronized the display to a color sequential backlight. Moving the color information into the temporal domain, maintained the color pixel density identical to the cell density. A 192 x 192 pixel active matrix circuit with integrated drive and scan functions was fabricated in thin-film single-crystal silicon, using standard IC processing, and subsequently placed on glass to form a transmissive AMLCD. The first assembled 2.5- x 2.5-in. monochrome display shows greater than 85 percent pixel functionality. The speed, low leakage current, and high drive capability of single-crystal silicon devices should allow the fabrication of displays with integrated system-level peripheral circuitry, high pixel density, and improved contrast and optical aperture ratios.
