Monitors Made of Oil and Water?

Water and oil don't mix, right, but, in fact, that has formed the basis of the new screens with remarkably bright colors to be introduced by Liquavista, an offshoot of Philips.

electro wetting

The innovative display screens are actually based on electro-wetting technique where each pixel cell is packed with a small amount of dyed oil and water and a layer of a material that can be converted from hydrophobic (water repelling) to hydrophilic by applying electricity.

The mechanism:

When the material is hydrophobic, the water pushes away from it and forces the dyed oil against the surface. The pixel, which has a light source behind it, then projects the color of the dyed oil out. In hydrophilic mode, the water draws toward the surface, shoving the dyed oil to the side, changing the color projecting from the pixel. Flipping the pixels rapidly allows a screen containing millions of the pixel cells to create an image.
