Abstract: The present invention is directed to a display device which includes an array of sealed micro-cups containing particles of a designated electric and magnetic characteristic suspended in a solvent wherein a surface of a plurality of the sealed micro-cups constituting a transparent surface. The display device further includes an electromagnetic image writing/drawing pen for manually applying an electromagnetic filed on the particles of the designated electric and magnetic characteristic in the micro-cups to form an image viewable from the transparent surface. More particularly, the particles of the designated electric and magnetic characteristic are charged particles and the writing and drawing pen is an electrical writing/drawing pen.
