A patented display technology for use for handhelds and mobile devices. These screens do not need to be backlit, which is a drain on the device battery — instead they are illuminated by sunlight and the movement of the liquid inside the screen. A display is produced using the principles of Electrowetting to create a pixel modulator. Inside, oil is colored with a dye, which enables the creation of a display when different pixels are independently activated to make an image. Liquavista was developed under the Philip Research Labs in Eindhoven. The company, Liquavista BV, is backed by Philips.
