Abstract

A drive circuit for a color display device comprising a plurality of pixels which are wired in matrix through a plurality of data signal lines and a plurality of scanning signal lines; the drive circuit comprising an input means for sampling three-primary color image signals for one line which are inputted through three input lines during a given period t, to write the signals in a memory, and an output means for reading the three-primary color image signals during a certain t/2 period to output the signals to three output lines, and reading the three-primary color image signals during an additional t/2 period different from the certain t/2 period to output the signals to the three output lines. When the drive circuit is used in, e.g., an active matrix liquid-crystal display device, display can be free of flicker and can be in a high resolution.
