Abstract

The invention discloses colored electronic paper and a manufacture method thereof. A display area of the colored electronic paper comprises a plurality of pixels. Each pixel comprises at least three sub pixels. The colored electronic paper comprises an electrophoretic medium and a color film. In each sub pixel, the electrophoretic medium comprises first electrophoretic particles, second electrophoretic particles, third electrophoretic particles and fourth electrophoretic particles, which are different in color state. The color film is arranged on the first side of the electrophoretic medium. In each pixel, the area sum of the sub pixels of first colored light reflected by the first electrophoretic particles and the area sum of the sub pixels of second colored light reflected by the second electrophoretic particles are smaller than the area sum of the sub pixels with the color film respectively. Third colored light can be formed after light rays penetrate the color film. The first colored light, the second colored light and the third colored light are different in color. Through large color film area, light intensity loss after the light rays penetrate the color film is compensated, and the risk of color cast and dark fringes in the display area of the colored electronic paper is reduced.

Description

technical field [0001] The present invention relates to the technical field of electronic paper, and more specifically, to a color electronic paper and a manufacturing method thereof. Background technique [0002] The realization of electronic paper technology mainly includes cholesteric liquid crystal display technology, electrophoretic display technology and electrowetting display technology. Among them, the electrophoretic display technology uses an electric field to make the color particles in the electrophoresis move according to the magnitude and direction of the electric field, and remains unchanged in the absence of an electric field. It realizes electronic paper display through the reflection of the color particles on external light. Electrophoretic display technology combines the advantages of ordinary paper and electronic displays and has low energy consumption. It has obvious advantages in the field of static display (labels, books, newspapers, billboards, bus st...
