Apparatus and method for an electronically controlled color filter for use in information display applications

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