Embodiment Construction

[0194] 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.

[0195] Specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0196] figure 1It is a schematic diagram of the first solution to realize the protection of ...

Abstract

The present invention proposes a switch-type safe double-sided electronic paper, comprising a first grid array electrode; a first non-volatile display material; a common electrode and a common electrode lead; a second non-volatile display material; a second grid Array electrode; the first grid array electrode, the first non-volatile display material, the common electrode, the second non-volatile display material and the second grid array electrode form a stack; in the first grid An electronic switch is set on the electrode lead of at least one grid electrode of the array electrode; and / or an electronic switch is set on the electrode lead of at least one grid electrode of the second grid array electrode; and / or An electronic switch is arranged on the electrode lead of the common electrode. The invention effectively solves the problem that the electronic paper is illegally or accidentally changed by an external electric field or applied voltage, effectively maintains the information presented by the electronic paper, and provides an effective technical solution for the application of the electronic paper in certificates, official documents and other fields.

Description

technical field [0001] The invention relates to a switch-type secure double-sided electronic paper, in particular to a secure electronic paper capable of maintaining information displayed on the double-sided 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 characteristic that...
