(Summary description)Electronic ink (Electronic Ink) is actually a new type of material, which is the product of the multidisciplinary development of chemistry, physics and electronics. This material can be printed on the surface of any material to display text or image information. Since e-ink is a liquid material, it is vividly called e-ink "water". Suspended in this liquid material are hundreds of microcapsules about the size of a human hair, each consisting of positively and negatively charged particles. As long as a certain process is adopted, this electronic ink can be printed on the surface of glass, fiber or even paper media. Of course, these electronic ink-carrying carriers also need to undergo special treatment, and a simple structure is constructed for each pixel in it. The pixel controls the circuit so that the e-ink can display the images and text we need. When a negative electric field is applied to both ends of the microcapsules, the white particles with positive charges move to the negative electrode of the electric field under the action of the electric field, and at the same time, the particles with negative charges move to the bottom of the microcapsules. ”, then the surface will show white. When a positive electric field is applied on both sides of the adjacent microcapsules, the black particles will move to the top of the microcapsules under the action of the electric field, and the surface will appear black. E-ink technology can turn any surface into a display screen. It allows us to completely jump out of the conceptual constraints of the original display device and slowly penetrate into every corner of our living space. But it's not enough for e-ink to be displayable. For an electronic display device that hopes to replace paper media, it must be readable and portable.
