A whiteboard of the future

Researchers from the University of Tokyo have developed an inexpensive handwriting-enabled e-paper suited to large displays like whiteboards.
The display is made from black-and-white microparticles about 0.1 millimeter in diameter. One hemisphere of each particle is black and carries a negative charge, while the other is white and carries a positive charge. The particles are sandwiched between two electrodes. By switching the direction of the voltage across the electrodes the background display can be switched between black and white.

Such "twisting ball" displays are not new, but the researchers have integrated a magnetic field control component with the original electric control. The black side of the microparticles also contains magnetic nanoparticles that make it possible to write on the screen.
