Samsung has once again made our hopes for 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 that they had successfully fabricated “nearly single crystalline Gallium Nitride on amorphous glass substrates”. Quite simply, they worked out how to make LED screens from ordinary glass.
Which could not sound too impressive; all things considered glass has been used in producing TV’s because they were first produced. However it’s all concerning the constituents 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 way to create an LED screen that substitutes sapphire with ordinary glass. The same kind of glass that’s inside your windows!
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 proportions. With this GaN wafer may be as much as 400 times larger! And furthermore, as 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.” Suppose that! In just 10 years’ time your bedroom window could be a top quality LED TV! Well, maybe not that soon, nevertheless the implementations of these technology will be really important on earth of entertainment, sports, and advertising and how we experience them. You could thus feasibly imagine getting out of bed towards the view of a rainforest in Latin America, or perhaps the salt plains in Bolivia. Anything will be possible and all of the futuristic movies where actors would change the evbryr on their own windows to whatever suited them has stopped being an impossibility.
You never know, 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. One important thing is made for sure, if this technology becomes mainstream, there will never be a cause to look from the window at the gloomy day outside, you decide what is will 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 enjoyed a great beginning, already ideal for stuff like Christmas trees and theatrical lighting (being that they can be applied in several colors.) However, the investigation and growth and development of LED lighting has since grown and can continue to grow.
More technical especially more complicated LED’s are those being created in ultraviolet, blue as well as white shades. For instance: an ultraviolet GaN LED,Blue type of LED works with a wide band gap semiconductor in InGaN LED in addition to InGaN (indium gallium nitrate). The idea was there, however, it absolutely was 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 Leds can be created in several way. For instance: When 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 the GaN.
