摘要

Abstract: Liquid crystal displays by virtue of their flat profile, low volume and low power offer the user a number of advantages over CRTs, without compromising on the image quality. High definition (1000 line) flat panel displays enhance image recognition, which improves the viewer's ability to resolve images. High definition displays are required over a wide spectrum of sizes for HMDs through HDDs, to multifunction consoles. These size and complexity requirements may be uniquely met with ferroelectric liquid crystal display (FLCD) technology. The fast line address times (l.a.t. $APEQ@20 $mu@s) may be traded off to meet complexity, color and grayscale. This paper describes the latest developments in FLCD design to produce temporal and spatial dither grayscale. These exploit new developments in material response times and fast drive schemes developed at DRA Malvern. The increased speed provided by the Malvern drive schemes also allows color to be implemented in a temporal manner similar to temporal grayscale. A new method to add color to existing fast displays using a frame sequential technique is also described.!16
