Problems solved by technology

Light, thin, and flexible screens are the direction of major manufacturers' efforts. However, the existing screens can be made thinner and thinner, but they are easily damaged by external forces, that is, the so-called "broken screen" appears.
Traditional ITO touch screens are relatively fragile and cannot be bent significantly, so they cannot be used on flexible display screens or their lifespan is extremely short, and they cannot meet the needs of wearable devices for screens. In addition, the cost of ITO materials is high

Abstract

The invention discloses an ultrathin flexible electronic ink touch display screen. The display screen comprises a touch layer and a display layer, wherein the touch layer comprises a substrate, an electrode pixel layer, an electronic ink layer and a graphene transparent conductive layer; the electrode pixel layer is arranged on the substrate; the electronic ink layer is arranged on the electrode pixel layer; the graphene transparent conductive layer is arranged on the electronic ink layer; and the display layer is arranged on the graphene transparent conductive layer. According to the display screen, graphene replaces ITO to serve as a transparent electrode of the display screen; a flexible graphene touch screen is manufactured; effective combination of flexible touch and flexible display is realized by a double-sided graphene structure; and the ultrathin flexible electronic ink touch screen is manufactured, so that the screen is lighter and thinner, the flexing can be realized to a greater extent, and a simple structure on the electronic ink layer makes a reading image clear.

Description

technical field [0001] The invention relates to the field of electronic reading display screens, in particular to an ultra-thin and flexible electronic ink touch display screen. Background technique [0002] With the rapid development of science and technology, people can enjoy new ways of reading such as new media services, electronic reading of newspapers and periodicals, and QR code reading through terminals such as computers, digital TVs, mobile phones, and tablet computers. It is also the rapid development of science and technology and the fast-paced lifestyle that make more people alienate books, newspapers, and periodicals, and it can even be said that they gradually lose their good reading habits. In recent years, an e-book similar to traditional books and newspapers, e-books using e-ink have attracted widespread attention, such as Amazon’s kindle e-book, which is a portable e-book reader using e-ink technology. Provides a paper-like reading experience with minimal ...
