OLED-TV Display/Monitor Technology News

A European study uniting the world’s top lighting researchers hopes to produce the next generation of illumination technology. It could potentially triple the efficiencies achieved with compact fluorescent lighting and open a whole new range of applications.

OLEDs also offer potential applications. Because they are flat, light and thin they could be used in display applications, like computer screens or, one day, billboards. They are light and can be made on plastic or flexible substrates, so they could create flexible displays or electronic ‘paper’

A European consortium of the world’s leading lighting researchers from 24 universities, research institutes and industrial groups like Osram and Philips thought they could do better. Under the OLLA project, they came together to create high-brightness, organic light emitting diodes (OLEDs) for ICT and next-generation lighting applications. OLEDs use an organic layer to emit light, providing greater performance for less power.

OLEDs could one day emit nearly 100% of their power as light, overtaking even the best fluorescent tubes – currently standard technology for office lighting applications.

Lighting efficiency is measured in lumens per watt of electricity (lm/W) and lifetime. The best quality CFLs offer about 50 lm/W and 10,000 hours of operation. The OLLA project wants to equal this efficiency with OLEDs. Already OLLA demonstrated a white OLED of 25 lm/W with a 5,000-hour lifetime, the project’s second milestone.

“With this milestone we doubled the efficiency compared to an ordinary tungsten light bulb and expended the lifetime five times,” emphasises Peter Visser, project manager of OLLA. “In a few years time, we expect to be able to be as efficient as a compact fluorescent source. This gives OLED lighting a bright future!”
