720*400 matrix ferroelectric display operating at video frame rate

Results from the UK JOERS/Alvey collaboration on electrooptic performance are reported. The author examines the perceived engineering limits for the technology. These limits are based not only on experimental multiplexing studies, but also on the effects due to fabrication processes, conductor design, drive circuits, and temperature range requirements. Progress on a 720*400 matrix video-frame-rate ferroelectric-liquid-crystal monochrome display is also reported. Experimental results and supporting models of the display system indicate that ferroelectric liquid crystals are a feasible technology for high-resolution applications, offering high contrast and fast update rates. They also have potential for use as TV displays. Means of designing displays to operate over acceptable temperature ranges have been shown to be practical for a number of applications, but further work in this area is required.<>
