Light-emitting wallpaper may begin to replace light bulbs from 2012, according to a government body that supports low-carbon technology.
A chemical coating on the walls will illuminate all parts of the room with an even glow, which mimics sunlight and avoids the shadows and glare of conventional bulbs.
Although an electrical current will be used to stimulate the chemicals to produce light, the voltage will be very low and the walls will be safe to touch. Dimmer switches will control brightness, as with traditional lighting.
The Carbon Trust (a British group tasked with accelerating the switch to lower-carbon technologies) has awarded a $720,000 grant to Lomox, a Welsh company that is developing the organic light-emitting diode technology. The trust said it would be two and a half times more efficient than energy saving bulbs and could make a big contribution to meeting Britain's target of cutting carbon emissions by 34 per cent by 2020. Indoor lighting accounts for a sixth of total electricity use.
The chemical coating, which can be applied in the form of specially treated wallpaper or simply painted straight on to walls, can also be used for flat-screen televisions, computers and mobile phone displays.
As the system uses only between three and five volts, it can be powered by solar panels or batteries. Lomox, which will use the grant to prove the durability of the technology, believes it could be used in the first instance to illuminate road signs or barriers where there is no mains electricity.
