Organic Light Emitting Diodes are panels made from carbon based organics that usually emit light whenever electricity is passed through them. These diodes normally do not need filters and back lights compared to the inorganic diodes displays hence they are simple to make, thinner and more efficient and are known to have high quality pictures with very brilliant colors. They are also known for a wider viewing angle as well as faster response rate. Many of the mobile service providers use organic led lighting.
How these diodes work. Cathode known to inject electrons, anode removes electrons and an e missive layer is the basic structure composition of emitting diodes. Latest diodes devices can use many layers so as to increase their efficiency but all in all the basic function does not change. Light emitting diodes materials were discovered way back in nineteen sixties but the researchers started working on these technologies in the past twenty years.
As a compensation for this you have to apply more voltage so as to make them brighter. Due to this they have a shorter or lower lifetime. Inert matrix diode displays are small of up to three inch typically, therefore are used in display of character data and also small icons.
There are many ways of patterning and depositing the organic layers. Many organic diodes displays today are made of vacuum evaporation that is use of a Shadow Mask as a patterning material. This method is relatively simple though difficult in scaling up to very large substrates and inefficient. One of the available solutions to this challenge is use of organic diodes materials that are soluble and deposited by use of printing methods. Researchers have hope of these processes proving to be better scalable and efficient than the discussed vacuum deposition method or processes.
Uses of this technology are many and still not fully utilized. These devices are used in computer monitors, television screens, portable small system screens such as cell phones, watches, information and indication.
These companies have embarked on mass production of flexible panels. It is one of the world most advanced organic diode Fab probably. This is a roll to roll flexible technology with a capacity to produce million color tunable and flexible and efficient panels each and every month.
Focusing on such technology, today Samsung is considered to be the leading active matrix diodes producer. Samsung is making above two hundred million a year on displays and still it is expanding its production capacity throughout the world.
It is concentrating mostly on small displays of about five to ten inches mostly for tablets and phones. On the other hand life is good production of diode is only on large sizes panels, that is fifty to seventy inches mostly for applications for Televisions.
The used substrate is flexible and not rigid. Substrates can be of plastic and not glass as used by inorganic diode system. There are few limitations of organic diodes and include the manufacturing process which is very expensive right now. Short life span while green and red films have a longer lifespan, blue organics have a much shorter lifetime.
