DISPLAY APPARATUS INCLUDING OPTICAL MODULATOR AND IMAGE CONTROLLING METHOD

An aspect of the present invention features a display apparatus. The apparatus can comprise: an optical modulator that modulates brightness of the incident light from a light source corresponding to a driving voltage and outputs the modulated light; a driver integrated circuit that supplies a driving voltage according to an image control signal to the optical modulator; a scanner that projects the modulated light to a position on a screen; and an image control circuit that generates and outputs the image control signal from an input image signal for reducing influence of drive characteristics of the optical modulator. An image control circuit and a display apparatus according to the present invention can reflect drive characteristics of a micromirror of an optical modulator to output grayscale data corrected by using grayscale data outputted already and grayscale data desired to be outputted at now, thereby displaying purposed grayscale.
