Information reading device of electronic paper

Abstract

The invention provides an information reading device of electronic paper, which comprises a first grid array electrode, a second grid array electrode, a detection circuit array and an information processing circuit, wherein the first grid array electrode comprises first microelectrodes in the same quantity of the pixel points of the electronic paper; the second grid array electrode comprises second microelectrodes in the same quantity of the pixel points of the electronic paper; the detection circuit array comprises electrical characteristic detection circuits in the same quantity of the pixel points of the electronic paper; the electrical characteristic detection circuits detect electrical characteristic parameter values between the first microelectrodes and the corresponding second microelectrodes; the detection circuit array is connected with the information processing circuit; and the information processing circuit analyzes and identifies the state data of each pixel point according to the electrical characteristic parameter values. The technology can effectively read electronic information on the electronic paper to further copy the electronic information on the electronic paper to the traditional paper or other electronic paper and can further convert the electronic information into lattice image files or text files for storage.

Description

Electronic paper information reading device technical field The present invention relates to an information reading device for electronic paper, in particular to a device for reading information presented by electronic paper that has been digitized. Background technique The movable type printing invented by China is a major invention in ancient China. Its invention, development and spread to the world have made great contributions to human civilization. Modern laser printing and electronic typesetting printing make it easier for people to print text and patterns on paper. However, since the documents or data information obtained by these printing methods cannot be changed, a large amount of paper needs to be produced. Moreover, the used toner or printing ink for printing is still relatively large for environmental pollution. With the development of modern electronic technology, people have proposed various concepts of electronic paper, that is, paper that can update th...
