Organic Light Emitting Diodes (OLEDs) are striking the display and lighting of the current MarieFreebody conversation Stefan Grabowski, telling the commercialization of this technology.
[HC Lighting Network] Organic Light Emitting Diodes (O LEDs) are striking the display and lighting of the current MarieFreebody dialogue Stefan Grabowski, telling the commercialization of this technology.
Profile of the interviewee: Stefan Grabowski works at the Philips Research Laboratory in Germany. His research focuses on physical and OLED devices. Grabowski is also the project manager for the European OLED100.eu project, a European Union-funded R&D cooperation program to develop efficient OLED lighting products for the European lighting industry. The project participants include 14 units in six countries. .
Reporter: Can you explain how OLED works?
Grabowski: OLED is a solid-state lighting device, the principle is similar to its inorganic brother (referred to as LED). A typical OLED consists of two layers of organic material deposited on a transparent substrate. The upper and lower electrodes have a positive electrode and the middle is an electron transport material, which is a bit like a sandwich. One layer is responsible for emitting and transporting electrons from the cathode, and the other layer is responsible for conducting holes from the anode. When a voltage passes through these layers, the electron-hole pairs combine to emit light.
Unlike inorganic light-emitting diodes, the structure of OLEDs is easy to achieve high color gamut patterns or uniform white light, and the layers combined into OLEDs can be precipitated into a large area.
Reporter: Why is OLED R&D so important?
Grabowski: OLED has the potential to be an energy efficient light bulb. As we all know, more than a quarter of the electricity consumption in Europe comes from lighting, so energy-saving alternatives are an important area of ​​research and development. An important goal of the OLED100.eu project is to manufacture OLED products above 100 lm/W.
When high-efficiency OLEDs can be mass-produced, the cost will drop and they can be used in a variety of lighting applications. OLEDs offer users new options, which are flat and can be made large. They are very thin and can be made transparent or curved. The brightness and color of the OLED are adjustable, and new decorative lights can be designed to personalize the living environment.
Reporter: What is the main application of OLED? When will it be achieved?
Grabowski: There are two main application areas: display and lighting. Small OLED displays have been widely used on mobile devices such as cell phones, mp3s and personal electronic assistants. Large screens are also gradually entering the market, such as Sony released a 27-inch OLED TV, plans to push to the market in 2009
OLED lighting has completely different characteristics. These OLEDs are not composed of small pixels, but a large emission area, so the efficiency of such components must be high. The first OLED lighting appeared in some special applications, but more specific products will appear in the near future.
Our goal is to mount on a wall or ceiling so that we can get a large launch area. Transparent OLEDs can be mounted on windows, letting the sun pass during the day and glow at night, which is a wonderful thing.
