Abstract:
A method of driving an electronic paper display apparatus includes: providing a preprocessing signal in the first pulse signal to the first electrode in the display stage of the first image display stage, so that the first particles and the third particles are mixed, and the first particles and the third particles are closer to a display side of the display apparatus than the second particles; and providing a first sub-pulse signal in the first pulse signal to the first electrode in the display stage of the first image display stage after providing the preprocessing signal, so that the third particles are closer to the display side of the display apparatus than the first particles and the second particles and the microcup displays the third color.
