- The display is made from bicolored microparticles about 0.1 millimeters 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.Applying a voltage will immediately erase the drawings. In the absence of a voltage or magnetic field, the image is maintained without using any energy.
- The team is working to improve the contrast of the display, which they believe can be achieved by increasing the amount of black and white pigment in the microparticles. Eventually, the researchers believe their work could contribute to a world that is much less dependent on traditional paper.
