Disclosed is a color display apparatus including: A) an N (N is a natural number greater than 2) number of light sources each emitting a different color light in accordance with light source control signals controlling on/off states thereof; B) a one dimensional optical modulator element generating diffracted light by modulating the color light emitted from the light sources in accordance with optical modulator control signals; C) a scanner scanning and projecting the diffracted light from the one dimensional optical modulator element onto a display surface in accordance with scanner control signals; and D) an image control circuit receiving image signals, and transferring: the light source control signal, which turns on the N number of light sources each once, and turns on the light source having the weakest optical power thereamong once more, the optical modulator control signal, which contains light intensity information extracted from the image signal and corresponding to the turned on light source, and the scanner control signal controlling operation of the scanner which is based on the optical modulator control signal, to the light source, the one dimensional optical modulator, and the scanner, respectively so as to control the same.
