OLED Displays the next Flat-TV Generation?

Organic light emiting diode made up of semi-conductor device which is around 400 nanometers think.Its electroluminescent layer is made up of organic compounds which results emittion of light of different colors.The first oled-tv was Developed in Korea approximately around 1980's.They are made up of following parts:

1]Substrate Its made up of Glass,foil and plastic and is used to support the OLED.

Anode It adds electron holes or in technical term it removes the electrons when a current flows through the device.
3]organic layers These layers are made of oled-tv and
4]Cathode It inserts electron when current flows through the device.

There are also various types of OLEDs:
1]Transparent OLEDs
2]Top-emitting OLEDs
3]Foldable OLEDs and
4]White OLEDs

These are used in High defination tv,cell phones with color displays,advertisemnts and hoardings.

These devices are not much thick and they consume very less power.oled-tv can also provide bright display and consumes less power because it does not require back light function as in displays in Liquid crystal displays that is LCDs.Also,they react faster to changes in signal than in typical Plasma tv's and LCD's which are suited for motion pictures.

We have already seen that oled-tv are much thinner than LCD's and Plasmas,because they are made up of polymer films which make them flexible for motion pictures.

They are also much lighter in weight and more temperature range which makes it more durable.Also no backlight mean one less component to fail.Another advantage of OLED is that as its made up of plastic,they can me of larger sizes.

We have already discussed various advantages of OLED,but, it has its few disadvantages too.It being manufacturing process being too expensive right now resulting overall product to be costly.And secondly water can easily damage the OLEDs.Now that we know what is OLEDs, its types and its advantages & disadvanges lets see how the technology is growing or what future it holds.

Currently, OLEDs are used in cells,PDAs and other small screen displays.In 2004, sony corporation announced their plan to mass produce TVs with OLEDs.Kodak was the first in race in implementing OLED displays in its digital-camera's.Development in this field is growing tremendously and many digital companies are diving in this technologically lucrative pool.
