<p><P>PROBLEM TO BE SOLVED: To suppress irregularity in the light quantity of respective electrooptical elements over a long period. <P>SOLUTION: In each electrooptical element E, gradation is controlled in accordance with a drive signal Xi. Each unit circuit U includes a holding circuit 261, a selection circuit 263 and a drive part DR. The holding circuit 261 holds correction values Ca[i] and Cb[i] for the electrooptical element E. The selection circuit 263 selects either one of the correction values Ca[i] and Cb[i] held by the holding circuit 261. The drive part DR generates a drive signal Xi on the basis of a gradation value specified in the electrooptical element E and the correction value C[i] selected by the selection circuit 263. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
