Abstract

The invention relates to colored electronic paper. The color electronic paper comprises a first packaging layer, a color filter layer, a bonding layer, a second packaging layer, a transparent conducting layer, an electrophoretic display layer, a microcapsule, a driving layer and a substrate which are sequentially arranged from top to bottom, and further comprises a distributed Bragg reflector microarray structure layer. The distributed Bragg reflector microarray structure layer is arranged on any one layer below the color filter layer and above the electrophoretic display layer. The color display area of the electronic paper can be enlarged, the color saturation is improved, and the display brightness of a color electronic paper display screen is improved.

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, etc. [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. ...
