Problems solved by technology

Therefore, there is a multi-layer structure between the color filter layer and the display medium layer, which makes it easy for light to be totally reflected and scattered between the color filter layer and the display medium layer.
As a result, color electrophoretic displays are prone to color mixing, resulting in a decrease in color saturation; in addition, this distance will also limit the viewing angle of the display. When the viewing angle is too tilted, the light seen by the eyes will be affected by the color resistance of the adjacent color. color shift

Abstract

The invention relates to an electronic ink film laminated structure and a color electrophoretic display. The electronic ink film laminated structure comprises a display medium layer, an upper adhesive layer, a transparent substrate, a transparent conductive film and a color filter layer, the upper adhesive layer is located on the display medium layer. The transparent substrate is located on the upper adhesive layer. The transparent conductive film is located between the transparent substrate and the upper adhesive layer, wherein the transparent conductive film has a lower surface facing the upper adhesive layer. The color filter layer is located between the transparent substrate and the display medium layer. Due to the fact that the distance between the color filter layer and the display medium layer is shortened, total reflection and scattering of light rays between the color filter layer and the display medium layer are reduced. The color mixing problem of the display device can be reduced, so that the color saturation of the display device is improved, and the visual angle of the color electrophoretic display is increased.

Description

technical field [0001] The present disclosure relates to a color electrophoretic display. Background technique [0002] The color filter layer of the color electrophoretic display is mostly arranged above the electronic ink thin film laminated structure. Therefore, there is a multi-layer structure between the color filter layer and the display medium layer, so that the light is easily totally reflected and scattered between the color filter layer and the display medium layer. As a result, color electrophoretic displays are prone to color mixing, resulting in a decrease in color saturation; in addition, this distance will also limit the viewing angle of the display. When the viewing angle is too tilted, the light seen by the eyes will be affected by the color resistance of the adjacent color. Color shift. [0003] In view of this, how to provide a color electrophoretic display that can shorten the distance between the color filter layer and the display medium layer is still...
