ABSTRACT:
Aspects of the invention can provide a method for driving an electro-optical device, an electro-optical device and electronic equipment that can solve the insufficient supply of the data current and current fluctuation. In the driving method, a data current can be applied to a plurality of pixels provided to a display panel unit with same value through the data line regardless of grayscale data. Upon supply of the data current, in the pixel, a transistor selected in reproduction can be turned on such that a drive current corresponding to the data current output from a driving transistor is supplied to an organic EL element, thereby emitting light. A light-off signal can be supplied to the pixel at predetermined timing such that the organic EL element emits light only in the light-emitting period computed based on the grayscale data. The pixel to which a constant data current can be supplied emits light at a luminance corresponding to the grayscale data by changing the light-emitting period corresponding to the grayscale data.
