Patent ID: 8519994

Claim:
A method of driving an electrophoretic display having a first pixel and a second pixel adjacent to each other, wherein a gray level of the first pixel is controlled by a common electrode and a first pixel electrode, and a gray level of the second pixel is controlled by the common electrode and a second pixel electrode, the method comprising: setting a common voltage applied on the common electrode to be a first voltage during a first frame time; applying a second voltage different from the first voltage to the first pixel on the first pixel electrode for writing a first data signal into the first pixel during the first frame time; applying the first voltage to the second pixel on the second pixel electrode for retaining a second data signal of the second pixel during the first frame time, the second data signal being different from the first data signal; setting the common voltage applied on the common electrode to be the second voltage during a second frame time following the first frame time; applying the first voltage to the first pixel on the first pixel electrode for writing the second data signal into the first pixel during the second frame time; and applying the first voltage to the second pixel on the second pixel electrode for retaining the second data signal of the second pixel during the second frame time.
