Gallium Nitride – There Exists Certainly A Lot More Than Meets The Eye On This Page..

Samsung has once again made our hopes for living in a revolutionary wonderland a step closer.

Last October the electronics superstar announced their engineers had created a breakthrough in LED technology. An agent of Samsung’s Advanced Institute of Technology said that they had successfully fabricated “nearly single crystalline GaN on GaN on amorphous glass substrates”. Put simply, they determined steps to make LED screens from ordinary glass.

That could not sound too impressive; after all glass has been used in the production of TV’s given that they were first produced. However it’s all concerning the ingredients that make up the LED screen which makes this discovery so exciting.

Current LED TV’s generally use sapphire substrates (tiny pieces of sapphire) to develop an LED screen. A costly process I’m sure you can imagine. What Samsung has discovered is a means to create an LED screen that substitutes sapphire with ordinary glass. Exactly the same type of glass that’s in your windows!

Exactly what does this mean for the rest of us common folk? HUGE LED screens, that’s what. Current Gallium Nitride (GaN) LED TV’s on the market are 2-inches in size. With this GaN on sapphire may be just as much as 400 times larger! And furthermore, as they’ll be utilizing glass substrates they’ll be able to lower production costs.

Part of Samsung’s research team mused that “in 10 years, window panes will be used as lighting and display screens, giving personality to buildings.” Suppose that! In just 10 years’ time your bedroom window could be a top quality LED TV! Well, maybe not that soon, however the implementations of such technology will be very important on earth of entertainment, sports, and advertising and how we experience them. You can thus feasibly imagine getting up to the view of a rainforest in Latin America, or possibly the salt plains in Bolivia. Anything is going to be possible and all sorts of the futuristic movies where actors would alter the evbryr on their windows to whatever suited them is no longer an impossibility.

That knows, maybe twenty years from now ordinary life is going to be like living on the group of Star Treck. I suppose we could only hope. One thing is for sure, if this technology becomes mainstream, there should never be a cause to check out your window in the gloomy day outside, you choose what is will likely be that you get up.

The creation of LED began with the introduction of lighting devices along with gallium arsenide – particularly for infrared and red lighting purposes. Obviously, LED lighting enjoyed a great beginning, already useful for stuff like Christmas trees and theatrical lighting (being they can be used in a number of colors.) However, the study and development of LED lighting has since grown and will continue to grow.

More technical and particularly more advanced LED’s are the types being created in ultraviolet, blue and also white shades. As an example: an ultraviolet GaN LED,Blue kind of LED uses a wide band gap semiconductor in LED epi wafer as well as InGaN (indium gallium nitrate). The idea was there, however, it had been not until 1993 that high brightness of blue LED lighting was possible due to the work of any man named Shuji Nakamura through the Nicha Corporation.

White LED lights can be created in several way. As an example: As I mentioned, most LED white lights are based on InGaN and GaN structural designs. These lights are reported to be capable of emitting bluish light wavelengths between 450 nm and 470 nm blue from the GaN.
