Electronic paper display screen, display equipment and binding method

Abstract

The invention relates to the technical field of displaying, and discloses an electronic paper display screen, display equipment and a binding method. The technical purpose is to increase the substrateutilization rate of the electronic paper display screen, increase the yield of the electronic paper display screen and prolong the service life of the electronic paper display screen. The electronicpaper display screen comprises a substrate, electronic paper, a binding electrode, an electronic ink conduction structure and chip-on-film, wherein the substrate comprises a displaying area and a binding area, the electronic paper is arranged at one side of the displaying area of the substrate, and the electronic ink conduction structure which extends to the substrate binding area is arranged at the edge, close to one side of the binding area, of the electronic paper; the chip-on-film is electrically connected with the substrate through the binding electrode, and the end, close to the displaying area, of the chip-on-film is clamped between the substrate and the electronic ink conduction structure.

Description

[0001] technology field [0002] The invention relates to the field of display technology, in particular to an electronic paper display screen, a display device and a bonding method. Background technique [0003] E-paper display, also called digital paper. It is an ultra-thin, ultra-light display, which is understood as "a paper-thin, soft, rewritable display". Generally, a type of display technology that can achieve comfortable reading like paper, ultra-thin, lightweight, bendable, and ultra-low power consumption is called electronic paper technology; because it has both the characteristics of paper and can switch to display different screens for content display, Moreover, it saves power, low power consumption and foldable bending function, and the screen display is delicate and the viewing angle is wide. Compared with other display technologies, the biggest advantage is that the visual effect is good under the sun, and there are no dead angles. Domestic and foreign researc...

Problems solved by technology

As long as a certain process is adopted, this electronic ink can be printed on the surface of glass, fiber or even paper media to form electronic paper. Of course, these carriers carrying electronic ink also need to undergo special treatment. A simple pixel control circuit can make electronic ink display the images and text we need. Electronic ink technology can make any surface an electronic paper display. It allows us to completely escape the concept of the original display device and slowly Slow penetration into every corner of our living space, however, the existing electronic paper display still has slow response speed, slow conversion speed, complex manufacturing process, and is easily affected by the environment (water vapor, oxygen, etc.), resulting in poor yield rate. low performance, poor display effect, and short lifespan of good products, so how to improve the lifespan and precise bonding of flexible e-paper displays, as well as provide better visual display has always been a research hotspot at home and abroad.
