ABSTRACT:
A display apparatus includes an electrophoretic display device having a plurality of pixels arranged in a matrix, each pixel including charged particles in a dispersion liquid and a pair of electrodes disposed close to the dispersion liquid, and a position of the charged particles in the pixel providing a gradation, and a drive circuit for outputting a gradation signal to each pixel. The gradation of each pixel is influenced by gradation signals of adjacent pixels through an electric field interference between pixels. In addition, a correction circuit corrects the gradation signal at each pixel to compensate for the influence from the gradation signals of the adjacent pixels.
