Technology Advancement Through Organic Led Lighting

By April Briggs


This system of technology is commonly known to be a current technology that generates efficient, thin and radiant displays. In this article the application of the technology will be expounded further showing clearly the distinction between passive and active technology of matrix. The term active matrix and passive matrix talk about diode display method. When dealing with passive matrix is where there is limitation of size and resolution though it is easy and cheap as compared to active matrix. In case of active matrix it mainly depends on capacitors for storage to preserve the row pixels thus allows large resolution while also supporting large size display with an array of active matrix. This system of organic led lighting is very hard to create though they have no limitations when it comes to size, resolution restrictions still maintaining efficiency.

Passive technology applies easy control scheme by allowing one to control each line simultaneously with a sequence of row in a display. The pixels in this system are always off due to lack of storage capacitor.

How to create a panel. To come up with a diode several simultaneous steps are followed. The step starts by cleaning a substrate, come up with back plane by circuitry driving and switching, depositing and arranging the organic layers in a pattern. Eventually encapsulate entire system to protect it from moisture, oxygen and dust damage.

There exist several methods of depositing and patterning these natural layers. A lot of diodes displays that we have today are created from vacuum evaporation that utilizes shadow mask. These shadow mask act as patterning materials.

Companies such as Samsung and Philips are among the largest consumers of this technology. Philips already produces glass panels that are flexible and still in process of coming up with plastic panels that are bendable. Philips on the hand is focused on producing efficient, functional, bright and homogenous panels.

The invention can sometimes be utilized in light sources with the aim of large space light emitting elements and general purpose area illumination. Since the idea is still in its early stages of development, emission of light per unit square cubic is less as compared to inorganic light emitting since they are built to be used as point light sources.

Just like any other technology, this idea has its share of challenges bases on industries they are to be used. Their production is soluble based, performance of soluble organic diodes is quite satisfactory, encapsulation of diode that is flexible, and lifespan of material. Reducing the evaporation process has also proved to be quite a challenge and the possibilities of system expansion.

The benefits of organic diode are quite many. They utilize plastic materials, use of lighter organic layer or materials in the system, very flexible and thin compared to LED layers.

Samsung Company is currently concentrating on production of small but flexible panels that can be applied in wearable gadgets and cell phones. It is specializing in production of five to ten inch displays for tablets and other mobile phones. It is believed that this technology has not been fully exploited and that in the near future such companies with still increase their production capacities.
