Forget ultra-thin TVs, low-power mobile phones and sparkling camera screens, cutting edge OLED technology will soon be found in the humble light-bulb.
University of Florida materials science and engineers have achieved a new record in the efficiency of blue organic light-emitting diodes - reaching a key milestone of 50 lumens per watt.
This is about the same as today's energy-saving compact fluorescent bulbs, and three times better than old school incandescent bulbs.
Being able to generate blue light efficiently is particularly important as it is a key component to making natural-looking white light - a problem some eco-bulbs have had in the past.
Florida researchers are hoping to eventually be able to make OLED bulbs that give 100 lumens per watt of pure white light.
A key advantage of OLED bulbs is that they are tunable: each OLED is an individual light, which means differently coloured OLEDs can be combined to produced different shades of light — red, green, blue or rich, warm white light for the home.
