OLED lighting goes mainstream in 2011 says Displaysearch!

All about White OLED lighting

OLED technology now is mainly used in display applications such as TVs and handset products and lighting applications, which have had less attention in the market before.

Although OLEDs used in lighting applications are not expected to become popular in the next few years and will initially target niche markets, the technology has several advantages over that of conventional lighting. First among the advantages is slimness. The thickness of OLED panels for lighting applications could reach less than 1mm. Such a characteristic could allow OLED lighting placed directly on ceilings rather than hang from them. In addition, flexibility is another advantage, which may allow OLED lighting to be used when designing for spaces with limited conditions.

OLEDs are a flat light source, emitting diffuse light from a potentially large active area. They do not need light distribution elements, thus reducing the cost for the whole lighting panel. In contrast, LEDs as main competitor are a point source technology which needs light distribution elements to achieve flat panel lighting. Additionally OLEDs use low peak brightness on large area, LEDs provide very high brightness on small area. Due to this fact, LEDs are optimal for point-like light sources, OLEDs are suitable for large area flat light sources. Using large-area OLED with higher efficiency will allow complete lighting solutions based on OLED technology. OLED will substitute existing lighting technologies, but will mainly generate new applications, owing to the unique properties of large-area diffuse light generating with adjustable color. Starting in the near future, OLED lighting will boost the OLED fabrication worldwide. The market research company IDTechEx expects already for 2011 a billion dollar market.

November 2009 Update:

Osram ORBEOS

ORBEOS is the first Organic light emitting diode light source from OSRAM Opto Semiconductors for premium quality functional lighting. The new energy-efficient surface-emitting panel is especially suited to applications in the premium segment such as architecture, hotels and catering, offices, private homes and shops.

The ORBEOS panel has a round lamp surface of 80mm diameter, is only 2.1mm thick and weighs 24g. These limited dimensions ensure plenty of different usage options. With an efficiency of 25lm/W, the panel beats that of conventional halogen lamps.

Its warm white colour temperature (2,800K, CRI up to 80) matches the warm light of an incandescent lamp and is therefore suited to lighting that is atmospheric and functional at the same time. Especially in homes, museums, restaurants or hotels, OLEDs also rate highly with their pleasant, non-glare light.

LEDs are actually a kind of building block – a new type of magic material – that can be combined with others to produce a striking new and creative whole. OLEDs in clothing, furniture, vehicles, jewelry, works of art: the possibilities are endless. But just hearing about OLEDs isn’t enough to be able to fully appreciate their unique characteristics and potential. That’s the purpose of the exhibit and the online OLED shop. We want to make it possible for people to see, touch and experience OLEDs for themselves. And if they get inspired, Philips Lighting is always interested in co-development and partnerships. When it comes to OLEDs, just about the only limit is your imagination.”

At the end of the project period, the OLLA project* consortium presents
its final milestone: the basic technology for a white OLED (Organic Light-
Emitting Diode) light source, with an efficacy of 50.7 lumens per watt at
an initial brightness of 1.000 cd/m² based on the Novaled PIN OLED
technology.

OLED100.eu lighting video:

OSRAM Opto Semiconductors and celebrated lighting designer Ingo Maurer have unveiled a revolutionary lighting application based on organic LEDs (OLEDs) at the Light+Building Fair in Frankfurt am Main, Germany (April 6-11, 2008). Ingo Maurer is the first to use OLEDs from OSRAM in a functioning table light. The limited-edition light, known as “Early Future,” shines with tiles directly from the OSRAM laboratory and demonstrates the enormous potential of using OLEDs to create future applications with eye-catching illumination and design elements.

In addition, OLED lighting is more stable than that of ordinary lighting. Compared to LED or conventional fluorescent lamps, OLED lighting is more like sunlight, which is more comfortable for viewing.

Earlier this month, Osram Opto Semiconductors said the company has developed a transparent white OLED tile. Such a development opens up possible applications such as partitions that are almost invisible by day and can provide a pleasant diffused light at night. The OLED prototype has achieved a luminous efficiency of more than 20lm/W at a brightness of 1,000cd/m2, said Osram.

Why do fireflies glow?

In warm summer nights you can see them: Small fluorescent insects known as fireflies or glowworms. But, how is this illumination or "glow" produced?

White OLEDs emit white light that is brighter, more uniform and more energy efficient than that emitted by fluorescent lights. White OLEDs also have the true-color qualities of incandescent lighting. Because OLEDs can be made in large sheets, they can replace fluorescent lights that are currently used in homes and buildings. Their use could potentially reduce energy costs for lighting. In the next section, find out about the pros and cons of OLED technology and how it compares to regular LED and LCD technology.

The challenge in this area is to make organic LEDs (OLEDs) that can compete with existing light sources in efficiency, stability, colour quality and operation lifetime. Ching-Fong Shu of the National Chiao Tung University, Hsinchu, and colleagues have now created a white light OLED that fulfils several of these prerequisites. They combined a blue-emitting polymer with a green-emitting polymer and a red emitter to produce their promising device.

LEDs are devices which convert electricity to light. Current passing through the device generates an excited state, which then decays to the ground state emitting a photon. Because of the increased efficiency of LEDs over conventional light sources such as incandescent light bulbs there is a potential for huge energy savings. LEDs that use organic polymers to emit the light are of particular interest because they are expected to be cheap to produce.

Konica Minolta Holdings, Inc., Konica Minolta Technology Center, Inc. and the General Electric Company announced that they have signed a strategic alliance agreement in March 2007 to accelerate the development and commercialization of OLED (Organic Light Emitting Diode) devices for lighting applications. The goal is to bring OLED lighting to market within the next 3 years.
