OLED refers to organic light-emitting diode. The term “organic” denotes to the occurrence of organic carbon-based molecules in the emissive (light-emitting) coating. In a single pixel of OLED the organic layer is inserted between two conductors, acathode and an anode. Stereotypically, both or one of the conductors are translucent. It reacts when electricity is passed through the organic layer and then it emits light.

OLED is being advertised as the futuristic technology which will create a history in world of digital display technology. It will offervarious advantages over both Plasma screen and LCD technologies.

Nowadays the thickness present in the LCD is because it requires a backlight. Whereas OLED screens create their own light and thus do not trust on a backlight. This permits the manufacturers to make the displays to very thin specifications.The screens which are made of OLED pixels offer animpressivelyenhancedqualityimage and much better viewing angle. The light outputs in these screens are managed by each individual pixel which allows awfullyrestricted dimming and greater colour precision.

The manageable sizes of the OLED panels make them more flexible. In result itallows the OLED screens to be mounted on incline surfaces such as pillars. It would also make for far greater movability as an OLED screen could possibly be moved up for easier transference. OLED creates its own light as a result it consumes less energy than LCD screens and hencethey are more valuable for environment.

OLED technology has some disadvantages too. These screens are more expensive for the buyers also for the manufacturers. But with the growth of novel “printing” methods these screens can be produced in affordable prices. General Electrichas already started working on roll-to-roll printing method. This method is very much similar to the newspapers printing.
