Full-color electronic paper and manufacturing method thereof

Abstract

The invention discloses full-color electronic paper and a manufacturing method thereof, and belongs to the technical field of full-color electronic paper.A layer of material capable of being patterned is coated on a back plate, and at least one pixel unit is manufactured on the material capable of being patterned; barrier layers are arranged at two ends of any two of the red pixel region, the green pixel region and the blue pixel region; the cover plate is attached to the back plate, so that the two regions, provided with the barrier layers, in the red pixel region, the green pixel region and the blue pixel region are in a closed state, and the other region is in an open state; the corresponding turbid liquid is poured into the area in the open state, and after pouring is completed, curing treatment is conducted on the two ends of the area; sequentially eliminating the barrier layers arranged at the two ends of the two areas in the closed state; reflection and penetration of light can be effectively improved, control is simple, the refreshing speed is increased, gray scale use is supported, and display colors are rich.

Description

technical field [0001] The invention belongs to the technical field of full-color electronic paper, and relates to a full-color electronic paper and a manufacturing method thereof. Background technique [0002] The electronic paper color filter technology mainly has the following two methods: The disadvantage of this solution is that the color gamut is too narrow and the reflectivity is too low, so that the product needs to increase the front light to have a better effect. Good color display; the scheme of mixing particles of various colors, although the color gamut is wider, but the refresh rate is too slow and cannot support the use of grayscale, and the display color is relatively monotonous. [0003] In the prior art, CN102629014A-method for preparing cholesteric liquid crystal panel and liquid crystal panel discloses: coating cured glue on the transparent electrode of the first electrode substrate; preparing at least one pixel unit on the transparent electrode of the se...

AI Technical Summary

Problems solved by technology

The above method is applied to the preparation of cholesteric liquid crystal panels. It uses three different heights to absorb liquid crystals of corresponding colors to pour liquid crystals of three colors into corresponding pixel areas, but it cannot be applied to electronic paper. The preparation method, the preparation of electronic paper uses a suspension mixed with colored particles and black and white particles. The viscosity of the liquid is relatively high, and it needs to be perfused with a relatively high pressure instead of being directly sucked, and the solution often has foreign substances due to the high pressure during perfusion. In the case of seepage, it is easy to cause contamination of the pixel area
