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.
An organic diode light bulb, consist of a film of thin material emitting light. The only technology with the ability to create a large area lighting panels and this is opposed to line or point lighting that is enabled by fluorescent bulbs and this diodes.
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.
Philips and other companies are the largest users of this technology in their products. The company also produce flexible glass panels and also on the process of producing bendable plastic panels. On the other hand Philips focuses on functional light efficient, bright and uniform panels.
The technology is also used in light sources for purposes of large area light emitting elements and general space illumination. Due to how young the stage of development is, diode emission of light per unit area is less than the inorganic solid state based LED as they are usually made for use as the point light sources.
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.
In case of single panels for instance they have achieved parameters of five grams. This parameter is a solution to weight hurdle that is facing the existing sources of light that is bulbs and tubes.
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.
