MAGNETIC-MATERIAL REVERSE DISPLAY PANEL

摘要

A magnetic-material reverse display panel comprising a dispersion liquid having a yield value, mainly consisting of fine-particulate magnetic display elements different in color on an S-pole side surface and on an N-pole side surface, a dispersion medium and a thickener, and sealed in a storing body consisting of a transparent display member and a rear-surface member, characterized in that the rear-surface member has a magnetic flux concentration member consisting of a ferromagnetic member, and the magnetic flux concentration member acts, when a display changing magnet approaches the front side of the panel, to intensify a magnetic field generated by the display changing magnet and put the magnetic field direction to be perpendicular to the rear-surface member. The magnetic flux concentration member can improve the sharpness of display/erasure on the magnetic-material reverse display panel and a display contrast.
