ABSTRACT:
A transflective electrophoretic display device is disclosed. The device is comprised of a transparent top substrate and both top and bottom substrates have an electrode structure. A plurality of separated walls and an electrophoretic display solution including a plurality of chromatic particles and a transparent liquid are imposed between the two substrates. A device with a display liquid or a filter plate is used to generate a variety of lights such as monochromatic, color-level or true color having a mixture of red, green and blue. The device of the present invention integrates the merits of the reflective and transmitted displayer, and can be used outdoors, indoors or in darkness. Otherwise, a back light module can compensate for the contrast of the displayer effectively.
