ABSTRACT:
An improved multi-color liquid crystal display system which is capable of making visual color representation of more than eight colors in a display panel, such as a liquid crystal display panel which is composed of liquid crystal cells having three primary color filters attached thereto. Lightness of a cell is controlled by causing the cell to be in "ON" state during M frames out of N frames (N>M) to thereby provide half-tone color representation of the cell. This enables increase of the number of colors represented with the three primary color cells more than eight by combining "ON", "OFF" and the "half-tone" states of the three primary color cells.
