Abstract
To provide a method for manufacturing an electro-optical device that is capable of controlling more smoothly brightness as compared with a control in every one frame and preventing large current from flowing when switching frames in a peak brightness control, a method of driving the same, and an electronic apparatus. A grayscale data average value operation unitperforms, for each line, an average value calculation of grayscale levels of images corresponding to images of an one-frame-length and outputs, based on average value for the one frame-length, mode signals Mto Mfor brightness control in each line. A driver input data converterrewrites, based on the mode signals Mto Mfrom the grayscale data average value operation unit, grayscale data HD for one line among grayscale data from a frame memoryinto grayscale data DD. The driver input data converteroutputs grayscale data DD which is image data for the one frame-length and whose brightness is adjusted in a signal generating circuit.
