Patent ID: 8063919

Claim:
A display device comprising: a display panel for displaying information; and a driving circuit arranged to drive the display panel; wherein the driving circuit is capable of changing, with a lapse of display time, a displayed color of information which is statically displayed on the display panel; the display panel includes a plurality of pixels arranged in a matrix configuration, and each of the plurality of pixels includes a first color dot corresponding to a first color, a second color dot corresponding to a second color, and a third color dot corresponding to a third color; the change in the displayed color is effected by varying display signal voltages supplied from the driving circuit to the first color dot, the second color dot, and the third color dot; the first color dot is an R dot corresponding to a red color, the second color dot is a G dot corresponding to a green color, and the third color dot is a B dot corresponding to a blue color, and the change in the displayed color is effected so as to compensate for a change in tristimulus values X, Y, and Z of the XYZ colorimetric system caused by a change in the luminance of one of the R dot, the G dot, and the B dot, the compensation being made by a change in the luminances of the other two of the R dot, the G dot, and the B dot; and the displayed color is changed between adjacent colors on a color wheel.
