Embodiment Construction

[0236] 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, even if the external electric field is removed, the optical state can still be maintained. 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.

[0237] Specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

Abstract

The invention provides switch type safe single-sided electronic paper, comprising a first grid array electrode, a nonvolatile display material and a second electrode which is a common electrode, wherein an independent grid electrode and an independent lead are arranged on each grid of the first grid array electrode; and the first grid array electrode, the nonvolatile display material and the second electrode form lamination. An electronic switch is arranged on a lead of at least a grid electrode of the first grid array electrode. When in the non-conducting state, the electronic switch ensureshigh impedance state or electric insulation state between the grid electrodes and the electrode leads. The technical scheme of the invention effectively solves the problem that the electronic paper is illegally or accidentally changed by external electric fields or external voltage, and the invention effectively maintains the information presented on the electronic paper and provides an effectivetechnical scheme for applying the electronic paper in such fields as certificates, documents, etc.

Description

technical field [0001] The invention relates to a switch-type 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 characte...
