ABSTRACT:
An electro-optical apparatus is provided that has a plurality of scanning lines, a plurality of signal lines, and electro-optical devices that are each being placed at an intersection of each of the scanning lines and each of the signal lines. The electro-optical apparatus is driven according to the amount of drive current supplied to the electro-optical devices. The electro-optical apparatus includes a lighting time measuring unit to measure a lighting time of the electro-optical devices, a lighting time storage unit to store the lighting time obtained by the lighting time measuring unit, and a drive current amount adjusting unit to adjust the amount of drive current based on the lighting time stored in the lighting time storage unit so as to correct the brightness of the electro-optical devices.
