Abstract
A solid state dot sequential color display device is disclosed. A color image is formed in a liquid crystal display panel by breaking each picture element up into its three primary color components and presenting them in an adjacent manner. The space occupied by a trio of primary color elements is smaller than the resolving power of the human eye. Techniques of large scale integration (LSI) are employed to effect the required addressing circuitry as applied to a matrix array of triads of reflective electrodes in the dynamic scattering liquid crystal display panel. Arrangements used to form the basic color cells involved are: (a) deposition of band-pass filters in front of the display and (b) deposition of band reflection mirror in back of the liquid crystal material.
