Driving method for driving electrophoretic display apparatus, electrophoretic display apparatus, and electronic device

1. A driving method for driving an electrophoretic display apparatus, the electrophoretic display apparatus including:

a display section including a plurality of pixels, each of the plurality of pixels including:

a pixel electrode and a common electrode opposing each other; and

an electrophoretic element interposed between the pixel electrode and a common electrode, the electrophoretic element including electrophoretic particles,

the driving method comprising:

erasing a first image displayed on the display section, during a process of rewriting the first image into a second image, by:

supplying the common electrode with a common voltage,

supplying the pixel electrodes of pixels among the plurality of pixels which are displaying one gradation out of a first gradation and a second gradation with a voltage corresponding to the other gradation out of the first gradation and the second gradation, the first gradation being different from the second gradation, and

supplying the pixel electrodes of pixels among the plurality of pixels which are displaying the other gradation with a voltage of the same level as the common voltage; and

displaying the second image on the display section, during the process of rewriting the first image into the second image, by:

supplying the common electrode with the common voltage,

supplying the pixel electrodes of pixels among the plurality of pixels which are targeted for displaying the one gradation in accordance with corrected image data with a voltage corresponding to the one gradation, and

supplying the pixel electrodes of pixels among the plurality of pixels which are targeted for displaying the other gradation in accordance with the corrected image data with a voltage of the same level as the common voltage,

wherein the corrected image data is image data obtained by correcting image data associated with the second image so as to:

reduce an area targeted for displaying the one gradation in comparison with an area of the second image displaying the one gradation, and

expand another area targeted for displaying the other gradation in comparison with another area of the second image displaying the other gradation.

2. The driving method for driving an electrophoretic display apparatus according to claim 1 ,

wherein the displaying includes selecting of one of first corrected image data and second corrected image data as the corrected image data,

wherein the first corrected image data is image data obtained by correcting the image data associated with the second image so as to reduce an area targeted for displaying the first gradation in comparison with an area of the second image displaying the first gradation and expand another area targeted for displaying the second gradation in comparison with another area of the second image displaying the second gradation, and the second corrected image data is image data obtained by correcting the image data associated with the second image so as to reduce an area targeted for displaying the second gradation in comparison with an area of the second image displaying the second gradation and expand another area targeted for displaying the first gradation in comparison with another area of the second image displaying the first gradation, and

wherein, during the selecting, in the case where the one gradation in the erasing is the first gradation, the first corrected image data is selected as the corrected image data, and in the case where the one gradation in the erasing is the second gradation, the second corrected image data is selected as the corrected image data.

3. An electrophoretic display apparatus comprising the driving method for driving an electrophoretic display apparatus as set forth in claim 1 .

4. An electronic device comprising the electrophoretic display apparatus as set forth in claim 3 .
