Fibre-optic screens could lead to longer battery life in laptops.
A new technique developed by L.E.S.S. (Light Efficient SystemS) could lead to a 30% reduction in energy use in computer screens, which account for around half of the energy use in laptops. The fibre-optic technique they have developed could find its way into commercial products in around four to five years.
Laptop screens are composed of different filters for colors and of a source of white light situated in the lower portion of the frame. With LED, which is currently used, 60% of the light remains trapped inside these diodes and accounts for a significant loss in efficiency. The fiber optics developed by L.E.S.S. could bring just as much luminosity and contrast while conserving a quarter of the energy. “That liberated power could be used by the processor to gain speed,” adds the entrepreneur.
