Embodiment Construction

[0237] 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.

[0238] Specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

Abstract

The invention provides stacked safe single-sided electronic paper which comprises a first conductive material layer, a second conductive material layer and a single-sided electronic paper material layer. The single-sided electronic paper material layer is arranged between the first conductive material layer and the second conductive material layer; the first conductive material layer, the electronic paper material layer and the second conductive material layer are integrated by a laminating or pasting process, and at least one conductive contact point or contact line or contact surface is formed between the first conductive material layer and the second conductive material layer. The technical scheme of the invention effectively solves the problem that electronic paper is illegally or exceptionally altered by an external electric field or external voltage, effectively maintains information presented by the electronic paper, and provides an effective technical scheme for applying the electronic paper to the fields of certificates, official documents and the like.

Description

technical field [0001] The invention relates to a laminated secure single-sided electronic paper, in particular to a secure electronic paper capable of preventing abnormal modification of information displayed on the 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...
