Abstract
PURPOSE: To obtain a display unit featuring the facilitated rewriting by forming the colloidal solution by including the magnetic fine grains of a fixed diameter into the liquid in a high density to then enclose such solution into the element formed into a plate form and then inverting the magnetizing direction for plural mangets distributed with every element.
CONSTITUTION: Magnetic fine grain 1 of a fixed diameter is included into water or hydrocarbon-group liquid 2 in a high density to form the colloidal solution. The grid-type convexity is formed to container 3 which is formed into the plate form and transmits the light to constitute the element unit, and the above mentioned colloidal solution is enclosed in this container with every element unit. Then magnet 4 and 5 with coil 6 attached are distributed oppositely outside the element unit, and shielding plate 7 and 8 are provided to hide grain 1. Thus, one element of the display unit is formed. The information is applied to coil 6 of this element to give the magnetization and inversion to magnet 4 and 5 in order to carry out the writing and erasion for the element unit.
