Samsung has once again made our hopes for living in a innovative wonderland one step closer.
Last October the electronics superstar publicised their engineers had made a breakthrough in LED technology. A representative 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 worked out how to make LED screens out of ordinary glass.
Which could not sound too impressive; in the end glass has been used in the creation of TV’s because they were first produced. However it’s all concerning the components that define the LED screen that 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 imaginable. What Samsung has discovered is a method 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 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 particular GaN on sapphire could be just 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 ten years, window panes will be used 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, perhaps not that soon, nevertheless the implementations of such technology can be really 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 South America, or perhaps the salt plains in Bolivia. Anything will likely be possible and all of the futuristic movies where actors would modify 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 is going to be like living on the list of Star Treck. I assume we can only hope. One thing is for sure, when this technology becomes mainstream, there will never be a cause to appear your window at the gloomy day outside, you choose precisely what is is going to be which you awaken.
The development of LED began with the development of lighting devices along with gallium arsenide – particularly for infrared and red lighting purposes. Obviously, LED lighting enjoyed a great beginning, already useful for things like Christmas trees and theatrical lighting (being they can be used in several colors.) However, the investigation and development of LED lighting has since grown and definately will keep growing.
More complex and particularly more complicated LED’s are the types being created in ultraviolet, blue and also white shades. For instance: an ultraviolet GaN LED,Blue form of LED works with a wide band gap semiconductor in LED wafer as well as InGaN (indium gallium nitrate). The concept was there, however, it had been not until 1993 that high brightness of blue LED lighting was possible thanks to the work of the man named Shuji Nakamura from your Nicha Corporation.
White Leds can be created in more than one way. For example: When I mentioned, most LED white lights are derived from InGaN and GaN structural designs. These lighting is said to be capable of emitting bluish light wavelengths between 450 nm and 470 nm blue from the GaN.
