71650-9 ABSTRACT OF DISCLOSURE An apparatus and method for producing a color display from a substantially monochromatic source utilizes a liquid crys- tal cell combination together with a plechroic filter to differ- entially polarize the light components comprising the light emit- ted from the source. The liquid crystal cells are connected in push-pull fashion to individually retard light by one quarter of a wave as a function of the control signal applied to them. A quar- ter wave plate followed by a linear polarizer completes the opti- cal combination. A signal at a first level applied to the cells causes transmission of one component color and blocks the other. A signal at a second level blocks the one component color and transmits the other. An intermediate level signal transmits both colors, resulting in a third, combination color.
