Abstract

The invention provides a contact point type safety one-side electronic paper which comprises a first grid array electrode, a nonvolatile display material and a second electrode, wherein each grid of the first grid array electrode is provided with an electrode and an electrode lead which are independent; the second electrode is a common electrode; the first grid array electrode, the nonvolatile display material and the second electrode form a laminated layer; information protection first conducting contact points which are connected by a lead are arranged on at least one grid electrode of the first grid array electrode; information protection second conducting contact points which are connected by a lead are arranged on the second electrode; and the first conducting contact points and the second conducting contact points are in a low impedance state or power conducting contact under the action of a certain pressure. With the technical scheme, the problem that the electronic paper is illegally or accidentally changed by an external electric field or additional voltage is effectively solved, the information presented on the electronic paper is effectively maintained, and an effective technical scheme for realization of applying the electronic paper in the fields of certificates, official documents, and the like is provided.

Description

Technical field

[0001] The present invention relates to a contact type safe single-sided electronic paper, in particular to a safe electronic paper capable of preventing the information displayed on the electronic paper from being abnormally modified. Background technique

[0002] The e-paper technology represented by E-ink's electronic ink and SIPIX's MicroCup is showing an increasing popularity trend. It has made great progress in the fields of e-books, mobile terminals, and portable devices, and has also begun to be applied in electronic newspapers. . Since the electronic paper can still maintain the display content without power supply, it has the advantage of energy saving. At the same time, the content displayed by the electronic paper can be updated as needed. Generally, the content update of electronic paper is to change the optical state of the pixels by applying an electric field in a certain direction to the pixels of the electronic paper. It is precisely because of ...
