Embodiment Construction
[0243] 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. From another point of view, each micro-unit of electronic paper is equivalent to a pixel. When each pixel presents different optical characteristics, the charge in each micro-unit is in a different position state. If the electric charge of each micro-unit is detected Properties identify the optical properties of each micr...

The invention provides an information copying method of electronic paper, which is used for copying information on the electronic paper; the method comprises the steps: the front of the copied electronic paper at the position corresponding to each pixel point is provided with a first electrode, and the back thereof is provided with a second electrode; electrical characteristic between the first electrode and the second electrode is detected; state data of the corresponding pixel point is distinguished according to the electrical characteristic; the front of the electronic paper for receiving copying information is provided with a third electrode at the position corresponding to each pixel point, and the back thereof is provided with a fourth electrode; the state data of each pixel point at the area storing the copied electronic paper is converted into voltage driving the state change of the pixel points of the electronic paper; the third electrode and the fourth electrode at the position corresponding to each pixel point in the area of the electronic paper for receiving the copying information are applied with the voltage driving the state change of the pixel points of the electronic paper. The method can effectively read the information on the electronic paper which is electronized, so as to further copy information on the electronic paper onto the traditional paper or other electronic paper.
Description
technical field [0001] The invention relates to an information copying method of electronic paper, in particular to a method for reading and copying information presented by electronic paper. Background technique [0002] 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. [0003] With the development of modern electronic technology, people have proposed various concepts of electronic paper, that is, paper that can update the content, such as E-ink's electronic ink a...
