The OLED prototypes that OSRAM Opto Semiconductors has developed as part of a research project are large transparent light sources only a few hundred micrometers thick. Thanks to new technology these organic light emitting diodes do not need separate encapsulation and can be made incredibly thin in any layout. The transparent test samples have a luminous area of 210 cm² and are already showing the enormous potential of OLED light sources. They offer a tantalizing glimpse of the extraordinary lighting applications that may one day become reality.

OLEDs have the potential to make exciting TVs (or computer displays). OLED are bright, ulta-thin, low power, and they show beautiful pictures. #break# Introduction to the OLED technology An OLED is made by placing a series of organic thin films between two conductors. When electrical current is applied, a bright light is emitted. Here's Kodak's description of OLEDs - "OLED displays stack up several thin layers of materials. They operate on the attraction between positively and negatively charged particles. When voltage is applied, one layer becomes negatively charged relative to another transparent layer. #break# As energy passes from the negatively charged (cathode) layer to the other (anode) layer, it stimulates organic material between the two, which emits light visible through an outermost layer of glass." #break# Today you can find small organic displays in many types of devices - Cell phones, A/V players, car audio systems, Digital cameras and PDAs. The main attraction today is the small size, the low power consumption and the great brightness. In december 2007 Sony will begin to sell the first OLED television (11" size). Here's our list of devices with an OLED display.

OLEDs have the potential to make exciting TVs (or computer displays). OLED are bright, ulta-thin, low power, and they show beautiful pictures. Sony will start selling OLED TVs in December 2007. But these will be small and pricey. The main issue is the lifetime (OLED displays degrade after a certain time), and also production cost are still high (Although theoretically OLEDs may become cheaper than LCD).
