Samsung has once again made our dreams of living in a revolutionary wonderland one step closer.
Last October the electronics superstar announced that their engineers had made a breakthrough in LED technology. An agent of Samsung’s Advanced Institute of Technology said they had successfully fabricated “nearly single crystalline GaN on GaN on amorphous glass substrates”. Put simply, they worked out how you can make LED screens from ordinary glass.
That could not sound too impressive; in the end glass has been utilized in the production of TV’s given that they were first produced. However it’s all concerning the ingredients that comprise the LED screen that creates 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 imaginable. What Samsung has discovered is a method to create an LED screen that substitutes sapphire with ordinary glass. The same type of glass that’s in your windows!
Precisely 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 might be as much as 400 times larger! And since they’ll be utilizing 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.” Imagine that! Within 10 years’ time your bedroom window might be a good quality LED TV! Well, perhaps not that soon, nevertheless the implementations of such technology will be really important in the world of entertainment, sports, and advertising and exactly how we experience them. You could thus feasibly imagine getting out of bed for the look at a rainforest in Latin America, or perhaps the salt plains in Bolivia. Anything will likely be possible and all the futuristic movies where actors would change the evbryr on their windows to whatever suited them is no longer an impossibility.
You never know, maybe twenty years from now ordinary life is going to be like living on the list of Star Treck. I suppose we are able to only hope. Something is perfect for sure, if this technology becomes mainstream, there will not be a reason to appear your window in the gloomy day outside, you decide precisely what is will be which you get up.
The creation of LED began with the creation 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 may be used in several colors.) However, the research and development of LED lighting has since grown and can continue to grow.
More complex and especially more complicated LED’s are those being created in ultraviolet, blue and also white shades. For example: an ultraviolet GaN LED,Blue type of LED utilizes a wide band gap semiconductor in LED wafer in addition to InGaN (indium gallium nitrate). The idea was there, however, it was not until 1993 that high brightness of blue LED lighting was possible due to the work of the man named Shuji Nakamura from the Nicha Corporation.
White LED lights can be created in several way. As an example: As I mentioned, most LED white lights are derived from InGaN and GaN structural designs. These lighting is reported to be capable of emitting bluish light wavelengths between 450 nm and 470 nm blue from your GaN.
