Technology Advancement Through Organic Led Lighting

By Tammie Caldwell


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.

inert matrix diode display utilizes a simple control scheme where you are in control of each line or row of the display in a sequence. These electronics also they do not contain any storage capacitor thus the pixels in each and every row are off almost all the time.

They are also used to make transparent and flexible panels and are color tunable. The diode emits soft beautiful diffused light. The closest source of light to natural light is in fact this technology with the exception of old incandescent lamps.

The first devices using this technology in the market used inert matrix and were sub displays on cell phones, and the radio decks for automobiles. These displays were usually small and with one or two colors. In 2007 and 2008 is when the Active matrix panels started emerging paving way for larger mobile video player displays, mobile phones and not forgetting digital cameras.

Materials Used. Many materials are available for making these devices. The basic division basically is between the small molecule and large molecule known as passive diode. They are mostly used materials for commercial diodes today as they are seen to be more efficient than the passive organic light emitting diode. Materials that emit light are classified into phosphorescent or fluorescent.

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.

There are several challenges faced by these technology based on industries which are but not limited to the following, Soluble based production processes, Soluble organic led performance, Flexible diode encapsulation, Material life time. That is especially of the blue material. Scaling of the evaporation processes is also a challenge and the system capacity for expansion.

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.

Both of these companies have also produced flexible panels that are used in wearable devices and mobile phones. The volume of production is still low but these companies in the near future are expected to expand and increase production capacity. This way both will come up with new products and thus forming factors to the market.
