ABSTRACT A electronic color filter system for controlling a picture element color signal includes three filter regions which selectively control spectral components of light transmitted sequentially therethrough. Each filter region has a liquid crystal host material and a dye guest component. The orientation of the liquid crystal host, determined by an electric field applied to the filter material, determines the absorption coefficient of the dye guest component to polarized light. By appropriate selection of the guest dye component and control of the electric fields applied to the host liquid crystal, the transmitted light can have a selected radiation spectrum. The transmitted light of a multiplicity of picture elements can be used to provide a full-color visual image display.
