Patent ID: 7339716

Claim:
A transflective electrophoretic display device, which is composed of a plurality of display cells, the display device comprises: a top substrate, which is a transparent substrate having a plurality of anisotropic reflective plates of the display device; a bottom substrate having a plurality of light plates and a plurality of electrodes so as to generate an electric field, and the bottom substrate is installed opposite to the top substrate; a plurality of partitioning walls, which are transparent materials and disposed between the top substrate and the bottom substrate so as to isolate the plurality of display cells; a display solution, which is composed of a plurality of pigment particles and transparent liquid so as to fill a space isolated by the top substrate, the bottom substrate and the partitioning walls; wherein the electric field in the display cell is changed to guide the behavior of the plurality of charged pigment particles in the display solution, a light emits to the anisotropic reflective plates of the top substrate through the partitioning walls, and the plates reflect the light to the display solution so as to radiate monochromatic or gray-scale effects.
