Samsung has yet again made our dreams of living in a revolutionary wonderland one step closer.
Last October the electronics superstar publicised their engineers had created a breakthrough in LED technology. A representative of Samsung’s Advanced Institute of Technology said they had successfully fabricated “nearly single crystalline Gallium Nitride on amorphous glass substrates”. Put simply, they determined how to make LED screens out of ordinary glass.
That may not sound too impressive; in the end glass has been used in the production of TV’s because they were first produced. However it’s all to do with the ingredients that comprise the LED screen which makes this discovery so exciting.
Current LED TV’s generally use sapphire substrates (tiny items 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. Exactly the same kind of glass that’s within your windows!
Precisely what does this suggest for the remainder of 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 wafer might be just as much as 400 times larger! And because they’ll be using 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 be used as lighting and display screens, giving personality to buildings.” Suppose that! In just 10 years’ time your bedroom window can be quite a good quality LED TV! Well, perhaps not that soon, nevertheless the implementations of the technology will be really important in the world of entertainment, sports, and advertising and how we experience them. One could thus feasibly imagine waking up towards the look at a rainforest in South America, or perhaps the salt plains in Bolivia. Anything will likely be possible and all sorts of the futuristic movies in which the actors would alter the evbryr on their own windows to whatever suited them is no longer an impossibility.
Who knows, maybe twenty years from now ordinary life will likely be like living on the group of Star Treck. I assume we can only hope. One important thing is made for sure, if this technology becomes mainstream, there should never be a cause to appear your window on the gloomy day outside, you decide what is will likely be which you get up.
The development of LED began with the creation of lighting devices with gallium arsenide – particularly for infrared and red lighting purposes. Obviously, LED lighting had a great beginning, already ideal for things like Christmas trees and theatrical lighting (being that they can be utilized in numerous colors.) However, the study and progression of LED lighting has since grown and will continue to grow.
More technical and particularly more complex 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 works with a wide band gap semiconductor in LED epi wafer as well as InGaN (indium gallium nitrate). The reasoning was there, however, it was not until 1993 that high brightness of blue LED lighting was possible due to the work of any man named Shuji Nakamura from the Nicha Corporation.
White Leds can be produced in multiple way. For instance: 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 from your GaN.
