Transmissive electrophoretic display with laterally adjacent color cells

An electrophoretic display comprising:

• a light-transmissive rear window;
• a light-transmissive front window;
• a plurality of cells located between the rear and front windows, each cell containing charged light-absorbing black pigment particles in a light-transmissive fluid, and wherein laterally adjacent cells are grouped together in threes to form multicolor pixels;
• a collecting electrode and a counter electrode associated with each cell, the electrodes being substantially non-obstructive to light and electrically cooperative with one another for removing pigment particles in the cells from the path of light and collecting them on the collecting electrode substantially out of the path of light when the rear window is illuminated from behind so that light can reach the front window without significant attenuation, and for dispersing the pigment particles generally uniformly throughout the fluid in the cells to substantially block the path of light when the rear window is illuminated from behind so that the light is significantly attenuated before reaching the front window;
• a red filter element associated with a first cell of each pixel, a green filter element associated with a second cell of each pixel, and a blue filter element associated with a third cell of each pixel;
• and
• a backlight located behind the rear window for passing light through the rear window and the cells to the front window for observation by a viewer of the display.
