Samsung has once again made our dreams of living in a futuristic wonderland one step closer.
Last October the electronics superstar declared that the engineers had produced a breakthrough in LED technology. An agent of Samsung’s Advanced Institute of Technology said that they had successfully fabricated “nearly single crystalline GaN substrate on amorphous glass substrates”. Put simply, they figured out how to make LED screens from ordinary glass.
That could not sound too impressive; in the end glass has been utilized in producing TV’s because 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 bits of sapphire) to construct an LED screen. A costly process I’m sure imaginable. What Samsung has discovered is a means to create an LED screen that substitutes sapphire with ordinary glass. The identical kind of glass that’s inside your windows!
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 proportions. With this GaN on sapphire might be as much as 400 times larger! And because they’ll be using glass substrates they’ll have the capacity to lower production costs.
Part 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 top quality LED TV! Well, maybe not that soon, however the implementations of such technology will be very important on earth of entertainment, sports, and advertising and how we experience them. You can thus feasibly imagine getting out of bed towards the look at a rainforest in South America, or possibly the salt plains in Bolivia. Anything will likely be possible and all the futuristic movies where actors would alter the evbryr on their windows to whatever suited them is not an impossibility.
You never know, maybe twenty years from now ordinary life will likely be like living on the group of Star Treck. I assume we could only hope. Something is made for sure, when this technology becomes mainstream, there should never be a cause to appear from the window in the gloomy day outside, you decide what is will likely be that you simply get up.
The creation of LED began with the introduction of lighting devices and with gallium arsenide – particularly for infrared and red lighting purposes. Needless to say, LED lighting had a great beginning, already helpful for stuff like Christmas trees and theatrical lighting (being that they can be utilized in a number of colors.) However, the study and development of LED lighting has since grown and definately will continue to grow.
More technical and particularly more complex LED’s are the types being created in ultraviolet, blue and even white shades. For example: an ultraviolet GaN LED,Blue form of LED utilizes a wide band gap semiconductor in LED epitaxial wafer as well as InGaN (indium gallium nitrate). The idea was there, however, it had been not until 1993 that high brightness of blue LED lighting was possible due to the work of the man named Shuji Nakamura through the Nicha Corporation.
White LED lights can be created in more than one way. As an example: When I mentioned, most LED white lights are based on InGaN and GaN structural designs. These lighting is reported to be competent at emitting bluish light wavelengths between 450 nm and 470 nm blue from your GaN.
