<P>PROBLEM TO BE SOLVED: To provide a method for driving an electronic circuit with which both high-speed display and sufficient display quality can be realized, the electronic circuit, an electrooptical device, a method for driving the electrooptical device, and electronic apparatus. <P>SOLUTION: A data current Idata corresponding to gradations of image data is supplied to a hold capacitor C1 and the capacitor C1 holds the amount of electric charges corresponding to the data current Idata. At this point, when the image data have high gradations, the data current Idata corresponding to the gradations are supplied to the hold capacitor C1. When the image data has low gradations, on the other hand, not a data current Idata corresponding to the low gradations, but a predetermined data current Idata for high gradations is supplied to the hold capacitor C1. Further, when the image data has the low gradations, the light emission period of an organic EL element emitting light with a driving current corresponding to the data current Idata is made shorter than its normal light emission period. Even when the data current Idata for the high gradations is supplied, display of low gradations is possible. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
