Claims (1)

[Scope of utility model registration request] It is equipped with a color matrix panel in which first, second, and third color display elements are arranged in rows repeatedly in the horizontal direction, and each of the R, G, and B primary color signals for each display element is sampled by a column driver circuit. In the color matrix panel display device, the column driver circuit inputs first, second, and third clock pulses having the same frequency but different phases by 120 degrees, and receives each of the input first, second, and third clock pulses. , second and third shift registers driven by second and third clock pulses, and each bit of said first shift register for applying a first color signal to a first color display element of said panel. a plurality of first gate groups, each of which is turned on by the output;
a plurality of second gate groups each turned on by each bit output of the shift register; 1. A drive circuit for a color matrix display device, comprising: a gate circuit including a plurality of third gate groups each of which is turned on when the third gate group is turned on.
