Abstract

The invention relates to an electrophoretic display micro-unit, electronic ink, an electrophoretic display diaphragm and an electrophoretic display. The electrophoretic display micro-unit comprises a microcapsule, electrophoretic particles and an electrophoretic liquid, wherein the electrophoretic liquid is sealed in the microcapsule, the electrophoretic particles are located in the microcapsule and suspended in the electrophoretic liquid, and a stabilizer is added to the electrophoretic liquid and adopts polyisoprene. According to the embodiment of the invention, polyisoprene is taken as the stabilizer, the cost is lower, bistability of an electronic display can be effectively improved, and the switching time of the display is kept within a reasonable limit. Besides, polyisoprene contains double bonds, so that the operability is high, and bigger space is reserved for further improvement of the stability of the electrophoretic display.

Description

technical field [0001] The invention relates to the field of display devices, in particular to an electrophoretic display micro-unit, electronic ink, an electrophoretic display membrane and an electrophoretic display. Background technique [0002] Electronic paper, a paper-thin, flexible and rewritable display, has gained popularity in recent years on billboards and price tags. E-paper relies on electrophoretic display technology for display, and has the characteristics of low energy consumption, good vision, reusability, and no electromagnetic radiation. Electrophoretic display technology can achieve a bistable state, and in order to improve the bistable state of the display more effectively, the prior art mainly introduces high molecular weight polyisobutylene (PIB) into the electrophoretic fluid as a stabilizer, and polyisobutylene will not significantly increase the suspending fluid. Viscosity, so it is easy to achieve a bistable effect, keeping the switching time of th...
