Color electrophoretic display

A color electrophoretic display, having an inner display region and an outer display region extending from an edge of the color electrophoretic display to the inner display region, the outer display region encircling and adjoining the inner display region, the color electrophoretic display comprising:

• a substrate;
• a segment electrode circuit layer disposed on the substrate and configured to display a first symbol within the inner display region and a second symbol within the outer display region;
• a transparent electrode layer disposed opposing the segment electrode circuit layer;
• an electrophoretic display medium layer disposed between the segment electrode circuit layer and the transparent electrode layer, wherein the electrophoretic display medium layer is controlled by an electric field that is produced and varied by the segment electrode circuit layer and the transparent electrode layer to change brightness;
• and
• a colored polymer protection film disposed on the transparent electrode layer, and comprising:
• a middle part including a plurality of first pigment particles dispersed among the middle part and configured to show a first background color of the first symbol within the inner display region;
• and
• a peripheral part including a plurality of second pigment particles dispersed among the peripheral part that extends from an edge of the colored polymer protection film to the middle area, the peripheral part encircling and adjoining the middle part, the second pigment particles configured to show a second background color of the second symbol within the outer display region.
