Problems solved by technology

However, since the display particles are pigment particles of inorganic pigments, the particle size cannot be controlled, and the particle size is from nanometer to micron, and the size of the display particles directly affects the response speed during the display thus prepared. When the display particles are larger When it is large, the display speed of electronic ink is slow and the response time is long, and the image definition displayed by the display device made by it will be poor

Abstract

The invention discloses electronic ink microcapsules, electronic ink and a preparation method. Each electronic ink microcapsule comprises a capsule wall and a dispersing agent, an organic solvent, a surfactant and display granules which are wrapped in the capsule wall, wherein the display granules are pigment granules of a nanometer-scale organic pigment. By controlling grain diameters of the display granules to be in a nanometer scale, the problems of slow display speed, long response time and the like of the electronic ink due to large display granules are solved, and the response speed anddisplay speed of the electronic ink are improved, so that a display device prepared from the electronic ink which is provided by the invention is high in the response speed and definition.

Description

technical field [0001] The invention relates to electronic ink technology, in particular to an electronic ink microcapsule, electronic ink and a preparation method. Background technique [0002] Electronic paper is an ultra-thin and ultra-light display device made of electronic ink displayed by electrophoresis. [0003] On the surface, the visual effect of electronic paper is similar to that of ordinary paper, and at the same time, electronic paper can be folded like ordinary paper. [0004] Electronic paper has the advantages of low power consumption, good visibility, reusability, flexible display, reversibility, bistable or multistable, low cost, easy realization of large-area display, and energy saving. [0005] As the key material of electronic paper, electronic ink can display changing images like a calculator or a mobile phone. [0006] In the prior art, electronic ink is composed of display particles, electrophoretic base fluid, and capsule wall materials. The displ...
