Abstract:
An active matrix image display device having a driver circuit, said driver circuit comprising:a first memory circuit for storing an in-bit digital image signal (where m is a natural number); a second memory circuit for storing an output signal of said first memory circuit; and a D/A converter circuit for converting an output signal of said second memory circuit to an analog signal, wherein said first memory circuit and said second memory circuit perform n storing operations (where n is a natural number greater than or equal to 2) within a time corresponding to one horizontal scan period, wherein the number of D/A converter circuits is equal to the number of horizontal direction signal lines divided by n, and wherein each of the number of said first memory circuits and the number of said second memory circuits is (mÃ—k)/n when the number of effective horizontal direction signal lines is k (where n is a natural number greater than or equal to 2).
