A method of controlling an electro-optical device includes, during image rewriting, executing a first control operation to supply a potential different from a potential on a counter electrode to a pixel electrode of a first pixel in a plurality of frame periods, executing a second control operation to supply the same potential as the potential on the counter electrode to a pixel electrode of a second pixel, which is adjacent to the first pixel and in which a gradation to be displayed during image rewriting is not changed, in at least some frame periods of a plurality of frame periods, and executing a third control operation to supply a potential different from the potential on the counter electrode to the pixel electrode of the second pixel in a frame period after the potential has been supplied in at least one frame period during the first control operation. |

1. A method of controlling an electro-optical device,
wherein the electro-optical device includes a display section which has a plurality of pixels at intersections of a plurality of scanning lines and a plurality of data lines with an electro-optical material between a pixel electrode and a counter electrode arranged to be opposite each other, and a driving section which executes potential supply multiple times to supply a data potential based on image data to the pixel electrode of each of the plurality of pixels in a predetermined frame period so as to display an image based on image data in the display section, the method comprises: during image rewriting to rewrite an image displayed in the display section, executing control operation A to control the driving section such that, in the frame periods, a second gradation potential based on a second gradation is supplied as the data potential to the pixel electrode of each pixel corresponding to a first region which is a region where a gradation to be displayed in the display section is changed from a first gradation to the second gradation different from the first gradation, a first gradation potential based on the first gradation is supplied as the data potential to the pixel electrode of each pixel corresponding to a second region of the display section which is a region where the gradation to be displayed in the display section is changed from the second gradation to the first gradation, and the same potential as the potential on the counter electrode is supplied to the pixel electrode of each pixel corresponding to each of a third region which is a region where the gradation to be displayed in the display section is not changed from the first gradation and a fourth region which is a region where the gradation to be displayed in the display section is not changed from the second gradation; and during image rewriting, executing a control operation B to control the driving section such that, in the frame periods, the first gradation potential is supplied as the data potential to the pixel electrode of each pixel corresponding to a fifth region, which is a region adjacent to the first region to surround at least a part of the first region at a predetermined width in the third region of the display section, the first gradation potential being supplied to the pixel electrode of each pixel corresponding to the fifth region simultaneously with supplying, in the control operation B, supplying the second gradation potential to the pixel electrode of each pixel corresponding to the first region, supplying the first gradation potential to the pixel electrode of each pixel corresponding to the second region, and supplying the same potential as the potential on the counter electrode to the pixel electrode of each pixel corresponding to each of the third region and the fourth region, and an end of a time period during which the first gradation potential is supplied as the data potential to the pixel electrode of each pixel corresponding to a fifth region does not extend beyond an end of a time period during which the second gradation potential is supplied to the pixel electrode of each pixel corresponding to the first region, the first gradation potential is supplied to the pixel electrode of each pixel corresponding to the second region, and the same potential as the potential on the counter electrode is supplied to the pixel electrode of each pixel corresponding to each of the third region and the fourth region. |
