Patent ID: 7061511

Claim:
A display device comprising: a display panel having a plurality of pixels arranged in a matrix form; a signal drive circuit generating a tone voltage corresponding to display data; a scan drive circuit generating a scan voltage for selecting a row of a pixel to which the tone voltage is applied; tone voltage lines coupled to said signal drive circuit and said plurality of pixels, for transferring said tone voltage form said signal drive circuit to said plurality of pixels; scan voltage lines coupled to said scan drive circuit and said plurality of pixels, for transferring said scan voltage from said scan drive circuit to said plurality of pixels; and a correction circuit which corrects said display data of (N+1) frame based on a differential between the display data of N-th frame and the display data of N+1-th frame and a tilt coefficient of correction data to post-change display data relative to before-change display data, wherein said tilt coefficient when the display data changes from a dark tone to a bright tone is different from said tilt coefficient when the display data changes from a bright tone to a dark tone.
