The organic light-emitting diode (OLEDs) brings large-scale areas to light.
Can we uniformly coat an area of six square meters with organic materials in two minutes? We say: Yes.
OLED televisions are illuminated by eight million organic pixels. An AIXTRON system would need just two minutes to coat an area of about six square meters with organic materials. With this area, a customer could produce six OLED televisions.
The organic light film – the core of an innovative light principle
Organic light-emitting diodes (OLEDs) are extremely light, consume little energy and provide brilliant colors and contrasts. They are already used in some products: In car radios, mobile phone and camera displays and MP3 players. The first OLED television sets – flat and curved TVs – with a screen depth of just 3 mm are commercially available. Research is currently still being conducted on electronic paper and on luminous wallpaper, which changes its color as desired and serves as a screen at the same time.
How is that possible? It has to do with the materials that are used for its manufacture. The thickness of an organic film is just one 500 nanometers, which is one 500 billionth of a meter or 500 millionth of a millimeter. This is one-hundredth of a human hair – and that is with extreme precision across the entire area. When electrical voltage is applied, these films develop an extremely high level of brightness.
AIXTRON views the development of materials to produce organic light-emitting diodes as being a new technology lighting up large areas. Our focus in this regard is on the vaporization of so-called small molecules (small molecule materials).
