UK OLED project will achieve near sunshine lighting

Thorn lighting company Durham is leading a research project, real objective to develop new OLED materials and equipment, to provide large area lighting applications, to replace the fluorescent lamp.

"We expect to develop high quality light sources like sunlight. Project leader Dr. Geoff Williams introduction.

OLED panel is expected to replace the ordinary fluorescent lamp, as well as one of the two bulbs of the other technologies, and the other is the use of AC power supply electroluminescent.

Project participants are Durham University and Cambridge display technology (CDT), they won the British Trade Ministry of industry and Commerce provided 1 million 600 thousand pounds funding. Total start-up funding of up to 3 million 300 thousand pounds.

"The university is the center for the analysis of polymer energy levels. "We're going to be able to look at the refactoring process and get feedback that helps develop," Williams said. "

In accordance with the agreement, CDT will provide OLED polymer materials, equipment formation and testing, as well as modeling and other technical support.

"The luminescent polymer material will be the process solution, thus providing the potential for low cost processing for large panels," CDT said.

The project will initially be away from plastic materials because of their poor water resistance. "The original product will use a solid matrix. The gate layer (located on the plastic substrate) has not reached the level of oxygen and moisture. "He did not elaborate on the type of solid matrix," Williams said.

Performance indicators, including color rendering, will exceed existing fluorescent lamps. "Peaks and faults will occur in the spectrum, but the fault is not very large. "Williams says.

Another goal is that, after three years of development, the 1000cd/m2 will be able to produce, and after a period of less than 20000 hours after the brightness down to Williams. He added: "according to my experience, brightness may be 80%. "

Electrical efficiency will be similar to fluorescent lamps. "The goal is to reach 50 lumens per watt within 5 years," Williams said. "The ultimate goal is 150-200 lumens / watt. In 2015-2016, we will reach this level. Wait until 2020, OLED will become the preferred light source. "
