METHOD OF DRIVING ELECTROPHORETIC DISPLAY DEVICE, ELECTROPHOTETIC DISPLAY DEVICE, AND ELECTRONIC APPARATUS
First Claim
1. A method of driving an electrophoretic display device, the electrophoretic display device comprising:
- electrophoretic elements including electrophoretic particles that is arranged between one pair of substrates;
a display unit formed of a plurality of pixels each including a pixel electrode, a pixel switching element, a memory circuit that is connected between the pixel electrode and the pixel switching element, and a switching circuit that is connected between the pixel electrode and the memory circuit; and
first and second control lines that are connected to the switching circuit, andthe method comprising;
extracting a length of the boundary between pixel data of a first gray scale level and pixel data of a second gray scale level from image data transmitted to the display unit as a characteristic amount;
determining whether an operation mode of an image displaying operation is to be switched based on the characteristic amount; and
switching the operation mode based on the result of the determination acquired in the determining on whether an operation mode is to be switched.

Abstract
There is provided a method of driving an electrophoretic display device including electrophoretic elements including electrophoretic particles that is arranged between one pair of substrates, a display unit formed of a plurality of pixels each including a pixel electrode, a pixel switching element, a memory circuit that is connected between the pixel electrode and the pixel switching element, and a switching circuit that is connected between the pixel electrode and the memory circuit, and first and second control lines that are connected to the switching circuit. The method includes extracting a length of the boundary between pixel data of a first gray scale level and pixel data of a second gray scale level from image data transmitted to the display unit as a characteristic amount, determining whether an operation mode of an image displaying operation is to be switched based on the characteristic amount, and switching the operation mode based on the result of the determination acquired in the determining on whether an operation mode is to be switched.
