Embodiment Construction

[0030] Electronic paper in related technologies, such as figure 1 As shown, it includes an upper electrode 02 and a lower electrode 01 arranged oppositely, and a conductive ink layer 03 located between the upper electrode 02 and the lower electrode 01. The conductive ink layer 03 includes a plurality of microcapsules 031, each microcapsule 031 Contains white particles and black particles, of which, figure 1 It is shown that the white particles are positively charged and the black particles are negatively charged for illustration. When the bottom electrode 01 is positively charged, the black particles are located on the side close to the bottom electrode 01, and the white particles are located on the side close to the top electrode 02, so that the area A appears white; when the bottom electrode 01 is negatively charged, the white particles are located near the bottom electrode. On the 01 side, the black particles are located on the side close to the upper electrode 02, so that th...

Abstract

The invention discloses electronic paper, a driving method thereof and a display device. The electronic paper comprises a first electrode layer, a second electrode layer, an electronic ink layer arranged between the first electrode layer and the second electrode layer, and a transparent piezoelectric layer arranged on one side, facing away from the electronic ink layer, of the second electrode layer. Through the arrangement of the transparent piezoelectric layer, charge accumulation occurs in the transparent piezoelectric layer when the electronic paper is subjected to external pressure, and avoltage of the second electrode layer in a pressure point region changes, thereby driving charged particles in the electronic ink layer to move, and enabling the electronic paper to have an editablefunction.

Description

Technical field [0001] The present invention relates to the field of display technology, in particular to an electronic paper, a driving method thereof, and a display device. Background technique [0002] Electronic paper is a kind of electronic display similar to paper. The visual effect is almost the same as that of paper. At the same time, it can be continuously refreshed like a liquid crystal display. It has the advantages of low power, thin thickness, and portability. [0003] Currently, electronic paper mostly uses microcapsule electrophoresis display technology. Its working principle is to use an electronic ink technology. The electronic ink is composed of millions of extremely small microcapsules. Each microcapsule contains white and black particles, respectively. With positive and negative charges, it is suspended in electronic ink and displayed under the action of electric field. However, the electronic paper in the related art only has a display function and cannot be e...
