Embodiment Construction

[0152] 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 size 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 presents the optical characteristics we need.

[0153] The electronic paper in the present invention does not have metal electrodes for printing or electronization to reduce the cost of the electronic paper. Instead, all the metal electrodes for printing or electronization are used as parts of the electronic paper printing device. Therefore, the printing and electronicization...

Abstract

The invention provides an electronic paper perfect printing device which writes information into double-sided electronic paper. The perfect printing device is special electronic equipment which carries out electronization on a piece of novel electronic paper formed through a laminated or a pasting process by a first non-conducting transparent layer, an electronic material first layer, an opaque conducting layer, an electronic material second layer and a second non-conducting transparent layer; the perfect printing device comprises grid array first electrodes, grid array second electrodes, a grid array first driving circuit, a grid array second driving circuit, a common electrode, a network information memory cell, an electronic paper placing part, an information control unit, a mechanical movement driving circuit and a mechanical movement actuator; and at the same time, the invention provides a method using the special electronic equipment to carry out electronization (printing) to the electronic paper. The method can not only simultaneously carry out double-sided electronization onto the electronic paper to improve the utilization ratio of the electronic paper and increase the electronization speed, but also can successively carry out double-sided electronization onto the electronic paper in a time-sharing manner.

Description

Technical field [0001] The present invention relates to an electronic paper printing device, and more particularly to a device that performs double-sided electronization (printing) of electronic paper. Background technique [0002] The movable type printing invented in 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, electronic typesetting and printing make it easier for people to print text and patterns on paper. However, because the documents or data information obtained by these printing methods cannot be changed, a large amount of paper needs to be produced. In addition, the carbon powder or ink used in printing is still polluting the environment. [0003] With the development of modern electronic technology, people have put forward the concept of various electronic paper, that is, paper that can update content, such as E-ink's electronic ink and microcap...
