Embodiment Construction

[0238] Electronic paper is a special paper coated with micro-units (also called pixel units) with electrophoretic or electrowetting properties. These micro-units have the characteristics of changing the optical state under the action of an external electric field, and the optical state After the change, the optical state can still be maintained even if the external electric field is removed. Therefore, the printing of electronic paper is actually to control the magnitude and direction of the external electric field applied to each micro-unit on the electronic paper, so that each micro-unit on the electronic paper exhibits the optical characteristics we need. In the present invention, "micro-unit" and "pixel of electronic paper" have the same meaning.

[0239] Specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

Abstract

The invention provides a single-sided electronic paper information protector, comprising a first conductive material layer and a second conductive material layer. The first conductive material layer and the second conductive material layer form a cavity which can contain electronic paper and are provided with at least one conductive contact point or contact line or contact surface. The technical scheme of the invention effectively solves the problem that electronic paper is illegally or accidentally altered by external electric filed or external voltage, effectively maintains information represented by electronic paper, and is an effective technical scheme which can apply electronic paper to the fields of certificate, official document, and the like.

Description

technical field [0001] The invention relates to a single-sided electronic paper information protector, in particular to an information protector capable of preventing abnormal modification of information displayed on electronic paper. Background technique [0002] E-paper technology, represented by E-ink's electronic ink and SIPIX's MicroCup, is becoming more and more popular. It has made great progress in the fields of e-books, mobile terminals, and portable devices, and it has also begun to be applied in e-newspapers. . Since the electronic paper maintains the displayed content without power supply, it has the advantage of energy saving, and at the same time, the displayed content of the electronic paper can be updated at any time as required. Usually, the content updating of the electronic paper is to change the optical state of the pixel by applying an electric field in a certain direction to the pixel of the electronic paper. It is precisely because of this characteri...
