Selective advantages of OLEDs

Theoretically, OLED is a light-emitting semiconductor device with only a few nanometers in thickness, utilizing fluorescence and/or phosphorescence mechanism by the conversion of electrical energy.

Each organic material in a multi-layered OLED device functions as hole and electron injectors, transporters, and emitters in between conductive anode and cathode.  There are many classifications and variations as shown in Table *.

With the explosive evolution of display markets and the comparative advantages, OLED is the next generation technology which follows LCD.  OLED has already been widely adopted by high-end users in small and medium sectors, and will soon penetrate the larger-sized display markets requiring an ultimate viewing angle and instant response time.

Similarly, a vast amount of R&D resources have been put world-wide to develop lighting applications ranging from decorative, luxury, automobiles, finally to general lightings to replace the conventional lightings. Although not limited to these technical advantages, OLED is believed to be the only alternative to provide eco-solutions in addressing environment and energy issues in the market today.
