This layer of organic piece of device is found between two electrodes, the anode and the cathode. OLEDs are used in television screens, computer monitors, mobile phones, PDAs and watches. The technology is one of the most promising lighting technologies for future lighting solutions. It overcomes the conventional restrictions by point source lighting technology such as LED or light bulbs. Its features are highly efficient among the area of light sources. This could be the starting point for a possible source of light innovations. Some ideas for possible light sources are the following: commercial signage, variant of colors, transparency and other flexible light sources.

The following are some advantages using OLEDs over flat panel displays made with LCD technology:

• Power Efficient –power consumption is less, although OLED is not currently affordable for the masses hence it is the manufacturing that is the most complex and expensive part of production than of a TFT LCD display.
• Light weight and flexible – this technology can be fabricated on flexible plastic substrates which is most probable for future fabrication of roll up displays.
• Wider viewing angles – colors of the images appears to be normal even when the viewing angle reaches 90 degrees than normal.
• Feedback time – it response more fast than a traditional LCD screens.
