ABSTRACT:
An electrooptical apparatus includes a plurality of scanning lines, a plurality of signal lines, and electrooptical devices, each being placed at an intersection of each of the scanning lines and each of the signal lines. The electrooptical apparatus is driven according to the amount of drive current supplied to the electrooptical devices. The electrooptical apparatus includes a brightness detection unit to detect the brightness of the electrooptical devices, and a drive current amount adjusting unit to adjust the amount of drive current based on the detected brightness result obtained by the brightness detection unit in order to correct for the brightness of the electrooptical devices.
