OLED-TV Display/Monitor Technology News

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.

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.

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.
