Abstract
PURPOSE: To obtain a lightweight and miniature display unit of plane structure by making it possible to rewrite information easily by using a heating element and a magnetizing magnet, by sealing a colloid liquid made of a liquid and magnetic particles in an element unit and by arranging several magnets whose curie points are high and low.
CONSTITUTION: Container 15, formed in a plane shape, allows light to penetrate, and in this container 15, convex part 16 is formed, thereby constituting an element unit. This element unit is filled with a colloid liquid, made of liquid 17 and magnetic particles 18, and sealed and magnets 20 with a higher curie point and magnets 21 with a lower curie point are arranged outside of the element unit. A write to the element unit is made by heating element 24 and the deletion of the element unit is done by magnetizing magnet 22. Through the operation of the heating element and magnetizing magnet, a rewrite is attained easily, and display can also be made with miniature and lightweight structure realized.
