摘要： To provide an electro-optical device, a driving method therefor, and an electronic apparatus which can accurately control the brightness of electro-optical elements in accordance with the signal level of a data signal. A brightness detection circuit 15 is provided which samples power-supply current Io every time one scan line is selected and which converts the power-supply current Io into a digital voltage signal DS having a digital value corresponding to the power-supply current Io. A light-emission-period control circuit 16 generates light-emission-period control signals H1 to Hn in accordance with a light-emission-period adjusting signal F corresponding to the digital voltage signal DS and outputs the light-emission-period control signals H1 to Hn to corresponding control-signal supply lines G1 to Gn. Further, light-emission-period control transistors of the pixels 20 which are connected to the corresponding control-signal supply lines G1 to Gn are on/off controlled, thereby controlling the light-emission period of the electro-optical elements.

摘要： 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 unit 33 performs, 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 M1 to M4 for brightness control in each line. A driver input data converter 34 rewrites, based on the mode signals M1 to M4 from the grayscale data average value operation unit 33, grayscale data HD for one line among grayscale data from a frame memory 31 into grayscale data DD. The driver input data converter 34 outputs grayscale data DD which is image data for the one frame-length and whose brightness is adjusted in a signal generating circuit.

A grayscale data average value operation unit 33 performs, 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 M1 to M4 for brightness control in each line.
