OLED is the name given to a structure created by a large number of organic thin film layers and 2 semiconductors. When the electrical current passes through this structure, it produces a radiant glow. This feature differs from the LCD screens we know about. Because the LCD screens used nowadays require a white background light to be displayed. Thanks to this feature of OLED screens, very fine and quality images are obtained.
The advantages of OLED screens are as follows:
– Exciting screens: unprecedented, very thin, flexible or transparent screens
– Low energy consumption: low energy consumption, especially in the need for portable devices.
– Higher brightness: higher brightness and excellent image quality in all respects.
– Lightweight: Very thin, flexible structure
Nowadays OLED screens are used in small sizes on mobile phones, portable music/video players, music systems on vehicles, digital cameras and PDA-type devices. It is preferred due to its low energy type and high brightness. In December 2007, Sony is expected to sell OLED television in 11-inch size (approx. 27 cm). In addition, the work of several firms together with the 42 inch OLED display is manufactured as a prototype. However, it is not currently released due to its high cost. As a result of the studies conducted in this field in the coming years, the prices of this technology will be at reasonable levels.
OLED screens are also available as light sources as well as images. In the years ahead, the bulbs that we use nowadays will replace the front.
OLED technology began to give the first signals that the daily lives would be a vast area of use. For example, you'll be able to adjust and use a dress made from OLED to the color you want.
Types of OLED technology:
PLED: Polymer light-emitting diodes (polymer light spreading diodes)
POLED: Patternable Organic Light-emitting diodes
TOLED: Transparent organic Light-emitting diodes
SOLED: Stacked OLED
LOLED: Inverted OLED
