Oil and water don't mix, but they can make bright colors, says a start-up spun out of Philips.

Liquavista, a new company created by Philips Research and New Venture Partners, will seek to commercialize a technique for making screens for phones and MP3 players that relies on the fact that oil and water repel each other.

In electrowetting, each pixel cell contains 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. 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.
