Color electronic paper display module and manufacturing method thereof

Abstract

The invention discloses a color electronic paper display module and a manufacturing method thereof. The color electronic paper display module comprises an electrophoresis display layer adhered to theupper part of an array substrate; a front light assembly which converts a point / line light source into a surface light source with high brightness and uniform brightness is further arranged above theelectrophoresis display layer; the front light assembly comprises a light guide plate; the light guide plate is provided with a diffusion point and an RGBW color light filter structure; the diffusionpoint and the RGBW color light filter structure are located on the same layer and are both integrated on the lower surface of the light guide plate; or the diffusion point and the RGBW color light filter structure are located on different layers, and are arranged on the lower surface and the upper surface of the light guide plate respectively. The light guide plate and the light filter are combined into one, so that the structure is greatly simplified; the color light filter is integrated on the light guide plate, so that the multi-layer coating is avoided, the thickness is reduced, the weightis lighter, and the color is brighter.

Description

technical field [0001] The invention relates to the technical field of color electronic paper, in particular to a color electronic paper display module and a manufacturing method thereof. Background technique [0002] E-paper is a new type of display material based on the principle of electrophoresis. It can not hurt the eyes like ordinary paper, and has the characteristics of ultra-low energy consumption, thin as paper, bendable and similar to the clarity of books. The display effect is similar to that of real Paper books are similar. At present, the electronic paper products on the market are basically black and white, while the color electronic paper products still have many shortcomings such as complex production process and low yield rate. [0003] For example, in the published patent "Color Electronic Paper Structure and Its Manufacturing Method (Application No.: 201110430449.8)" of Yuantai Technology, it is recorded that the RGB three-color photoresist is deposited o...

AI Technical Summary

Problems solved by technology

[0004] However, the common problems of the above solutions are: the color filter of the sheet must be separately added with an adhesive layer, plus the necessary front light components of the display module, the thickness of the entire product is too high, and there are many processes.
