Abstract

See full text

A twisted nematic liquid crystal display utilizes a premodifying or contouring circuit to provide inverse characteristics of the LCD. The contouring circuit compensates for the non-Lambertian characteristics of the liquid crystal display. This system provides a superior contrast ratio, gray-scale performance and stable chromaticity. The contour circuit can include a holographic diffuser.
