Samsung has once more made our dreams of living in a futuristic wonderland a step closer.
Last October the electronics superstar declared their engineers had made a breakthrough in LED technology. A representative of Samsung’s Advanced Institute of Technology said they had successfully fabricated “nearly single crystalline GaN on GaN on amorphous glass substrates”. Quite simply, they figured out steps to make LED screens from ordinary glass.
That may not sound too impressive; all things considered glass has been used in the creation of TV’s since they were first produced. However it’s all to do with the components that comprise the LED screen that makes this discovery so exciting.
Current LED TV’s generally use sapphire substrates (tiny bits of sapphire) to build an LED screen. A costly process I’m sure you can imagine. What Samsung has discovered is a way to create an LED screen that substitutes sapphire with ordinary glass. The same kind of glass that’s inside your windows!
Precisely what does this suggest 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 dimensions. With this particular GaN wafer may be around 400 times larger! And since they’ll be employing glass substrates they’ll be able to lower production costs.
Part of Samsung’s research team mused that “in ten years, window panes will double as lighting and display screens, giving personality to buildings.” Suppose that! Within 10 years’ time your bedroom window might be a top quality LED TV! Well, maybe not that soon, nevertheless the implementations of these technology can be really important on earth of entertainment, sports, and advertising and exactly how we experience them. You could thus feasibly imagine getting out of bed to the take a look at a rainforest in Latin America, or maybe the salt plains in Bolivia. Anything will likely be possible and all the futuristic movies where actors would modify the evbryr on their own windows to whatever suited them is not an impossibility.
That knows, maybe 20 years from now ordinary life is going to be like living on the set of Star Treck. I assume we are able to only hope. One important thing is for sure, once this technology becomes mainstream, there should never be a cause to look from the window at the gloomy day outside, you select what is will likely be that you simply wake up.
The development of LED began with the development of lighting devices and with gallium arsenide – particularly for infrared and red lighting purposes. Needless to say, LED lighting enjoyed a great beginning, already useful for stuff like Christmas trees and theatrical lighting (being that they can be used in a number of colors.) However, the study and growth and development of LED lighting has since grown and will keep growing.
More technical and particularly more complicated LED’s are the ones being created in ultraviolet, blue and even white shades. As an example: an ultraviolet GaN LED,Blue type of LED works with a wide band gap semiconductor in LED epitaxial wafer as well as InGaN (indium gallium nitrate). The concept was there, however, it had been not until 1993 that high brightness of blue LED lighting was possible thanks to the work of a man named Shuji Nakamura through the Nicha Corporation.
White LED lights can be created in multiple way. For example: When I mentioned, most LED white lights are based on 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.
