Gray-scale addressing technique for thin-film-transistor/liquid crystal displays

View publication

Abstract

An addressing technique allowing continuous-tone color images to be rendered on thin-film-transistor/liquid crystal displays having bilevel drivers is described. The technique uses multiple subfields per frame, with driver voltages changed synchronously with the field data. By using N bits of data per pixel, excitation is applied to the display one bit-plane per field for N consecutive fields. The technique is analyzed, its benefits and limitations discussed, and experimental results presented. Up to 16 gray levels have been demonstrated with good image quality.
