MAGNETIC MATERIAL REVERSAL DISPLAY PANEL

摘要

PURPOSE: A magnetic material reversal display panel is provided to display and erasure an image. CONSTITUTION: In a reversal magnetic display panel containing a dispersion liquid held by a supporting material, the dispersion liquid shows the yielding point and essentially consists of a particulate magnetic display body having the magnetic poles colored in different colors, a dispersion medium and a tackifier. The feature of the panel is that the total area of the S-pole faces or N-pole faces of the particulate magnetic display body is 60 to 500% of the display screen area of the display panel.
