Samsung has once more made our dreams of living in a revolutionary wonderland a step closer.
Last October the electronics superstar publicised 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 figured out how to make LED screens out of ordinary glass.
That may not sound too impressive; after all glass has been utilized in the production of TV’s since they were first produced. However it’s all to do with the components that comprise the LED screen which makes 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 you can think of. What Samsung has discovered is a means 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 dimensions. With this particular InGaN could be just as much as 400 times larger! And since they’ll be using glass substrates they’ll have the capacity 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.” Believe that! In just 10 years’ time your bedroom window could be a high quality LED TV! Well, maybe not that soon, however the implementations of these technology will be very important on the planet of entertainment, sports, and advertising and how we experience them. You could thus feasibly imagine getting up for the view of a rainforest in Latin America, or maybe the salt plains in Bolivia. Anything is going to be possible and all of the futuristic movies where the actors would modify the evbryr on their own windows to whatever suited them has stopped being an impossibility.
You never know, maybe twenty years from now ordinary life is going to be like living on the set of Star Treck. I assume we are able to only hope. One important thing is for sure, once this technology becomes mainstream, there will not be a cause to check out your window in the gloomy day outside, you decide what exactly is is going to be that you simply awaken.
The development of LED began with the development of lighting devices with gallium arsenide – particularly for infrared and red lighting purposes. Of course, LED lighting had a great beginning, already ideal for things like Christmas trees and theatrical lighting (being that they may be used 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 especially more advanced LED’s are those being created in ultraviolet, blue and also white shades. As an example: an ultraviolet GaN LED,Blue kind of LED utilizes a wide band gap semiconductor in LED epi 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 from the Nicha Corporation.
White LED lights can be produced in more than one way. For example: Because I mentioned, most LED white lights are derived from InGaN and GaN structural designs. These lighting is said to be competent at emitting bluish light wavelengths between 450 nm and 470 nm blue from the GaN.
