摘要： A liquid crystal display device has a circuit for selecting voltage levels based upon display data from an externally-supplied gray-scale voltage varying periodically. The circuit includes a plurality of series combinations of processing circuits. Each of the series combinations is associated with one of video signal lines coupled to pixels, and each of the processing circuits of a respective one of the plural series combinations is associated with a respective one of N display data lines for supplying the display data and with a respective one of plural time control signal lines for supplying time control signals varying in synchronism with the gray-scale voltage. Each of the processing circuits is disposed between two adjacent ones of the N display data lines. The time control signals uniquely determine one level of the gray-scale voltage in combination with the time control signals.
