Patent ID: 8102363

Claim:
A method for driving an electrophoresis display device that has a pair of substrates that sandwich an electrophoresis element that contains, without any limitation thereto, a plurality of electrophoresis particles and further has a displaying section that is made up of a plurality of pixels, the driving method of the electrophoresis display device comprising: an image-erasing step in which an old image displayed on the displaying section of the electrophoresis display device is erased, the image-erasing step of the driving method of the electrophoresis display device further including a first image-erasing sub step of displaying a first gradation in each of the pixels of a first area and displaying a second gradation in each of the pixels of a second area, where the pixels are grouped into the first area and the second area arrayed adjacent to each other in the displaying section of the electrophoresis display device, the first area being made up of either a single pixel or plural pixels, the second area being also made up of either a single pixel or plural pixels; and a second image-erasing sub step of displaying the second gradation in each of the pixels of the first area and displaying the first gradation in each of the pixels of the second area, wherein: each of the pixels of the first area and the second area comprises a pixel electrode formed on one of the pair of substrates and a common electrode formed on the other of the pair of substrates, a first electric potential is inputted into the pixel electrodes of the first area and a second electric potential is inputted into the pixel electrodes of the second area during the entirety of the first image-erasing sub step, the second electric potential is inputted into the pixel electrodes of the first area and the first electric potential is inputted into the pixel electrodes of the second area during the entirety of the second image-erasing sub step, and the first electric potential is applied to the common electrode during a first half of each of the first and second image-erasing sub steps and the second electric potential is applied to the common electrode during a second half of each of the first and second image-erasing sub steps.
