Samsung has once more made our dreams of living in a innovative wonderland a step closer.
Last October the electronics superstar announced that the 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”. In other words, they figured out how you can make LED screens away from ordinary glass.
That may not sound too impressive; after all glass has been utilized in the creation of TV’s since they were first produced. However it’s all related to the constituents that define the LED screen that 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 you can imagine. What Samsung has discovered is a means to create an LED screen that substitutes sapphire with ordinary glass. The same type of glass that’s in your windows!
What does this mean throughout 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 particular GaN wafer might be just as much as 400 times larger! And furthermore, as they’ll be employing glass substrates they’ll have the capacity to lower production costs.
A member of Samsung’s research team mused that “in ten years, window panes will double as lighting and display screens, giving personality to buildings.” Believe that! Within 10 years’ time your bedroom window could be a good quality LED TV! Well, perhaps not that soon, however the implementations of such technology will be very important in the world of entertainment, sports, and advertising and exactly how we experience them. You could thus feasibly imagine waking up towards the look at a rainforest in Latin America, or possibly the salt plains in Bolivia. Anything will be possible and all the futuristic movies where actors would change the evbryr on their windows to whatever suited them has stopped being an impossibility.
Who knows, maybe two decades from now ordinary life will be like living on the list of Star Treck. I suppose we can only hope. One thing is made for sure, when this technology becomes mainstream, there will not be a reason to look from the window in the gloomy day outside, you select precisely what is is going to be that you awaken.
The growth of LED began with the development of lighting devices along with gallium arsenide – particularly for infrared and red lighting purposes. Obviously, LED lighting had a great beginning, already useful for things like Christmas trees and theatrical lighting (being they can be applied in numerous colors.) However, the study and growth and development of LED lighting has since grown and definately will continue to grow.
More technical especially more advanced LED’s are those being created in ultraviolet, blue and even white shades. For instance: an ultraviolet GaN LED,Blue type of LED works with a wide band gap semiconductor in LED wafer as well as InGaN (indium gallium nitrate). The idea was there, however, it absolutely was not until 1993 that high brightness of blue LED lighting was possible because of the work of the man named Shuji Nakamura through the Nicha Corporation.
White Leds can be produced in several way. As an example: Because I mentioned, most LED white lights are based on InGaN and GaN structural designs. These lights are said to be capable of emitting bluish light wavelengths between 450 nm and 470 nm blue from the GaN.
