Patent ID: 6967639

Claim:
An image display device comprising: a plurality of signal lines for supplying display signals; a plurality of scan lines for supplying scanning signals; m (a number larger than 1) pieces of pixel electrodes connected with a given signal line, the pixel electrodes being serially selected in one horizontal scanning cycle; output circuits for outputting the scanning signals, the output circuits being connected with respective input terminals of the plurality of scan lines; a propagation circuit for propagating an inputted signal sequence, the propagation circuit being connected with the output circuits; a clock signal generator for generating a clock signal of a cycle defined as 1/m of one horizontal scanning cycle, wherein driving of m pieces of the pixel electrodes is controlled by combinations of the scanning signals supplied from a given plurality of the scan line, the signal sequence is composed of (m×m) pieces of signals, and said propagation circuit includes shift registers serially connected with said output circuits, said propagation circuit also includes partial propagation circuits connected between said shift registers connected with said respective output circuits, said partial propagation circuits being provided for outputting the inputted signal sequence after a (m−1) number of clocks, and said propagation circuit propagates the scanning signal between the output circuits in one horizontal scanning cycle.
