Abstract:
An electrophoretic display having a plurality of cells disposed between a light-transmissive front window and a reflective rear panel, comprising:multiple pixels each formed by multiple cells in a lateral adjacent arrangement relative to each other, each adjacent cell being between the front window and the reflective rear panel, and each cell containing charged, light-absorbing pigment particles in a light-transmissive fluid;a non-obstructing collecting electrode to substantially remove pigment particles in the respective cells from the path of light through the cell;a non-obstructing counter electrode cooperating with the collecting electrode to distribute the pigment particles in the respective cells to substantially block the path of light from the light source; anda color filtering medium for each respective cell, and wherein in three adjacent cells of each pixel, respectively, the color filter medium is red and the associated particles are cyan, the color filter medium is green and the associated particles are magenta, and the color filter medium is blue and the associated particles are yellow.
