Patent ID: 8890907

Claim:
A method of controlling an electro-optical device including a display section which has a plurality of pixels each having an electro-optical material between a pixel electrode and a counter electrode arranged to be opposite each other, and a driving section which supplies a data potential to the pixel electrode of each of the plurality of pixels, the method comprising: controlling the driving section such that, when an image displayed in the display section is rewritten from a first image displayed in a first gray level to a second image including a background image portion to be displayed in the first gray level and a main image portion to be displayed in a second gray level different from the first gray level, a voltage that is the same as a voltage supplied to the counter electrode is supplied to the pixel electrode of the pixel corresponding to the background image portion as the data potential and a voltage corresponding to the second gray level is supplied to the pixel electrode of the pixel corresponding to the main image portion as the data potential, wherein the main image portion of the second image includes an edge portion, and a non-edge portion, the non-edge portion excluding the edge portion, and in the controlling of the driving section when the image displayed in the display section is rewritten from the first image to the second image, the driving section is controlled such that at least one of a magnitude and an application time of the voltage supplied to the pixel electrode is smaller in the pixel corresponding to the edge portion than in the pixel corresponding to the non-edge portion.
