Samsung has once more made our dreams of living in a innovative wonderland one step closer.
Last October the electronics superstar announced that the engineers had created a breakthrough in LED technology. A representative of Samsung’s Advanced Institute of Technology said that they had successfully fabricated “nearly single crystalline Gallium Nitride on amorphous glass substrates”. Quite simply, they determined steps to make LED screens away from ordinary glass.
That could not sound too impressive; in the end glass has been used in the production of TV’s since they were first produced. However it’s all to do with the ingredients that define the LED screen which makes this discovery so exciting.
Current LED TV’s generally use sapphire substrates (tiny items 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 sort of glass that’s in your windows!
Precisely what does this mean throughout us common folk? HUGE LED screens, that’s what. Current Gallium Nitride (GaN) LED TV’s on the market are 2-inches in proportions. Using this GaN on sapphire could be around 400 times larger! And since they’ll be employing glass substrates they’ll have the ability to lower production costs.
A member of Samsung’s research team mused that “in 10 years, window panes will double as lighting and display screens, giving personality to buildings.” Imagine that! In just 10 years’ time your bedroom window might be a top quality LED TV! Well, maybe not that soon, however the implementations of these technology will be really important in the world of entertainment, sports, and advertising and just how we experience them. You could thus feasibly imagine getting up to the view of a rainforest in Latin America, or possibly the salt plains in Bolivia. Anything will likely be possible and all of the futuristic movies where the actors would change the evbryr on their windows to whatever suited them is no longer an impossibility.
That knows, maybe two decades from now ordinary life will be like living on the set of Star Treck. I guess we are able to only hope. Something is made for sure, once this technology becomes mainstream, there should never be a reason to check out your window at the gloomy day outside, you choose precisely what is will likely be which you wake up.
The development of LED began with the development of lighting devices along with gallium arsenide – particularly for infrared and red lighting purposes. Obviously, LED lighting enjoyed a great beginning, already ideal for things such as Christmas trees and theatrical lighting (being they can be used in a number of colors.) However, the investigation and growth and development of LED lighting has since grown and will continue to grow.
More complex and especially more complicated LED’s are the types being created in ultraviolet, blue as well as white shades. For example: an ultraviolet GaN LED,Blue kind of LED uses a wide band gap semiconductor in LED epitaxial wafer as well as InGaN (indium gallium nitrate). The concept was there, however, it was not until 1993 that high brightness of blue LED lighting was possible because of the work of the man named Shuji Nakamura from the Nicha Corporation.
White LED lights can be created in several way. For instance: When I mentioned, most LED white lights are derived from InGaN and GaN structural designs. These lighting is said to be competent at emitting bluish light wavelengths between 450 nm and 470 nm blue from the GaN.
