There is disclosed a method of driving an electrophoresis display device including a display unit having a plurality of pixel electrodes, a common electrode opposite to the plurality of pixel electrodes, and a first and second electrophoresis particles that are disposed between the plurality of pixel electrodes and the common electrode, the method including applying a first or second potential to each of the pixel electrodes, and applying the first or second potential, which is periodically switched, to the common electrode, when an image displayed on the display unit is rewritten, wherein, when the first and second potentials are periodically applied to the common electrode, the application of the first potential for a first application time and the application of the second potential for a second application time different from the first application time are repeatedly performed.

Method of driving electrophoresis display device based on electrophoretic particle migration speeds, electrophoresis display device, and electronic apparatus

In an image rewriting process of rewriting an image displayed on a display section by applying any one of a first electric potential, a second electric potential and voltage based on a driving pulse signal to each of a plurality of pixel electrodes and by moving electrophoretic particles by an electric field generated between the pixel electrodes and a common electrode, a first pulse application process which uses the driving pulse signal with the pulse width of the first electric potential being a first width, a second pulse application process which uses the driving pulse signal with the pulse width of the first electric potential being a second width longer than the first width, and a third pulse application process which uses the driving pulse signal with the pulse width of the first electric potential being a third width shorter than the second width, are sequentially performed.

Driving method of electrophoretic display device, electrophoretic display device and electronic apparatus

A method for driving an electrophoretic display device that includes a display unit having a plurality of pixels and an electrophoretic element provided between a pair of substrates is provided. The method includes displaying on the display unit a third image that includes an image component of a first image and an image component of a second image before changing the first image displayed on the display unit to the second image.

Method for driving electrophoretic display device, electrophoretic display device, and electronic device

An electro-optical device includes a first sub pixel and a second sub pixel. A pixel is configured by the first sub pixel and the second sub pixel only, and the first sub pixel and the second sub pixel emit light of different colors.
