Full-color imaging on amplitude-quantized color mosaic displays

Abstract

We discuss halftoning techniques appropriate for matrix-addressed electronic displays, such as thin-film-transistor (TFT) liquid crystal displays, which use color mosaics to implement multi-color operation via space-division-multiplexing. The error propagation method of halftoning is briefly reviewed and extended into the present context. Temporally dynamic techniques are described for rapidly refreshed displays, as is their implementation in digital hardware. Artifact suppression and the use of auxiliary passive light-optical image enhancement techniques are also addressed.
