LED Epitaxial Wafer – Maybe You’ve Been Curious About The Reason Why You Need This..

Samsung has yet again made our dreams of living in a revolutionary wonderland one step closer.

Last October the electronics superstar publicised that their engineers had created a breakthrough in LED technology. An agent of Samsung’s Advanced Institute of Technology said they had successfully fabricated “nearly single crystalline GaN substrate on amorphous glass substrates”. In other words, they figured out how you can make LED screens from ordinary glass.

That could not sound too impressive; after all glass has been used in the creation of TV’s since they were first produced. However it’s all related to the constituents that define the LED screen that makes this discovery so exciting.

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

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 particular GaN on sapphire may be as much as 400 times larger! And because they’ll be utilizing glass substrates they’ll be able to lower production costs.

A member of Samsung’s research team mused that “in a decade, window panes will double as lighting and display screens, giving personality to buildings.” Believe that! In only 10 years’ time your bedroom window might be a high quality LED TV! Well, perhaps not that soon, but the implementations of these technology will be very important on earth of entertainment, sports, and advertising and how we experience them. One could thus feasibly imagine getting up for the view of a rainforest in South America, or possibly the salt plains in Bolivia. Anything is going to be possible and all of the futuristic movies in which the actors would alter the evbryr on the windows to whatever suited them has stopped being an impossibility.

You never know, maybe two decades from now ordinary life will be like living on the group of Star Treck. I guess we can only hope. One important thing is made for sure, once this technology becomes mainstream, there will not be a cause to check out your window on the gloomy day outside, you select what exactly is will be that you simply awaken.

The development of LED began with the creation of lighting devices along with gallium arsenide – particularly for infrared and red lighting purposes. Of course, LED lighting enjoyed a great beginning, already useful for stuff like Christmas trees and theatrical lighting (being they can be applied in several colors.) However, the research and growth and development of LED lighting has since grown and can keep growing.

More complex especially more advanced LED’s are the types being created in ultraviolet, blue as well as white shades. For instance: an ultraviolet GaN LED,Blue type of LED utilizes a wide band gap semiconductor in GaN LED along with InGaN (indium gallium nitrate). The reasoning 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 Leds can be produced in multiple way. For example: As I mentioned, most LED white lights derive from InGaN and GaN structural designs. These lights are said to be able to emitting bluish light wavelengths between 450 nm and 470 nm blue through the GaN.
