Abstract

Results of theoretical and experimental studies on the generation of an arbitrary color are presented and compared. The theoretical results were obtained using the matrix representation method. The cell is operated in a tunable birefringence mode with a homogeneous aligned cell. The liquid crystal has a positive dielectric anisotropy. Colorimetric data are in good agreement with the given data within 0.50 CIE Unit color difference in the 1964 CIE (U*,V*,W*) color scale.
