Description

Switch type safe double-sided electronic paper

Technical field

The present invention relates to switch type safe double-sided electronic paper, particularly relate to the safety electronic paper that to keep the double-side electronic paper displayed information.

Background technology

With the little glass of box (MicroCup) of the electric ink of E-ink, SIPIX is that the electronic paper technology of representative presents the trend of popularizing day by day, obtains bigger progress in fields such as e-book, portable terminal, portable sets, also begins to use aspect electronic newspaper.Still keep displaying contents because Electronic Paper has under the situation that does not have power supply to supply with, have energy-saving advantages, can also upgrade the Electronic Paper content displayed at any time on demand simultaneously.Usually be the optical states that changes pixel by the electric field that the pixel of giving Electronic Paper applies certain direction to the content update of Electronic Paper.Also just because of this characteristic makes Electronic Paper not be suitable for the application that the information that need prevent is distorted.Because anyone can change or delete the shown content of Electronic Paper by the electric field that applies certain intensity.For in the application of electronic newspaper, owing to increased the interface that Electronic Paper is upgraded, cause anyone can change the content of electronic newspaper easily by this interface, when these are modified content and the newspaper that content is distorted is blazed abroad, with the damage that causes for interests of another, honor, also may produce disadvantageous societal consequence.Particularly, when Electronic Paper being used for certificate or the use of authentication text, will there be very big uncertainty in the reliability of its presentation information.

Because the employed a large amount of paper documents of people's daily life need prevent contents lost or be maliciously tampered, and as official document, certificate, standard, patent gazette etc., are very unfortunate if can not use the Electronic Paper of energy-conserving and environment-protective in these fields.
