Problems solved by technology

However, the transmission spectrum of the color filter film is usually too wide, and the transmission spectrum of the red, green and blue three-color filter film overlaps greatly, which will lead to less color and low color saturation of the electronic paper display, affecting its color display color gamut

Abstract

The invention relates to a color electronic paper. The color electronic paper includes a first encapsulation layer, a color filter layer, an adhesive layer, a second encapsulation layer, a transparent conductive layer, an electrophoretic display layer, microcapsules, a driving layer and a substrate arranged in sequence from top to bottom. The color electronic paper also includes a photonic crystal structure layer, and the photonic crystal structure layer is arranged on any layer below the color filter layer and above the electrophoretic display layer. The invention can expand the color display area of ​​the electronic paper and improve the color saturation.

Description

technical field [0001] The invention relates to the field of electronic paper research, in particular to a color electronic paper. Background technique [0002] Electronic paper (E-paper) is a new type of display material. It is a bistable display technology based on the principle of electrophoresis. Black and white, shades of color to express words and pictures, the display effect is very similar to real paper books. At present, electronic paper displays are widely used in electronic readers (e-books), electronic price tags, smart cards, watches, mobile phones, industrial instruments, meters, dynamic display billboards, and media products. [0003] The success of monochrome electrophoretic electronic paper from the laboratory to industrialization has given birth to the development of color electronic paper to meet people's diverse needs for reflective displays. However, many challenging issues remain to be overcome before colorization can be successfully achieved. [000...
