Samsung has once again made our dreams of living in a futuristic wonderland a step closer.
Last October the electronics superstar declared their engineers had created a breakthrough in LED technology. A representative of Samsung’s Advanced Institute of Technology said that 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; all things considered glass has been utilized in the production of TV’s since they were first produced. However it’s all concerning the components that define the LED screen that creates this discovery so exciting.
Current LED TV’s generally use sapphire substrates (tiny items of sapphire) to build an LED screen. A costly process I’m sure you can imagine. 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 inside 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 GaN wafer may be just as much as 400 times larger! And furthermore, as they’ll be utilizing glass substrates they’ll have the capacity to lower production costs.
A member of Samsung’s research team mused that “in a decade, window panes will be used as lighting and display screens, giving personality to buildings.” Believe that! In only 10 years’ time your bedroom window could be a top quality LED TV! Well, perhaps not that soon, but the implementations of the technology will be very important on the planet of entertainment, sports, and advertising and exactly how we experience them. One could thus feasibly imagine waking up for the view of a rainforest in Latin America, or maybe the salt plains in Bolivia. Anything will likely be possible and all of the futuristic movies where the actors would modify the evbryr on their own windows to whatever suited them is no longer an impossibility.
Who knows, maybe 20 years from now ordinary life will likely be like living on the list of Star Treck. I assume we are able to only hope. One thing is made for sure, once this technology becomes mainstream, there will not be a cause to appear your window on the gloomy day outside, you select what is will be that you awaken.
The development of LED began with the introduction of lighting devices with gallium arsenide – particularly for infrared and red lighting purposes. Obviously, LED lighting enjoyed a great beginning, already ideal for things like Christmas trees and theatrical lighting (being they can be used in a number of colors.) However, the investigation and development of LED lighting has since grown and can keep growing.
More technical and especially more advanced LED’s are the ones being created in ultraviolet, blue as well as white shades. For instance: an ultraviolet GaN LED,Blue form of LED utilizes a wide band gap semiconductor in GaN LED along with InGaN (indium gallium nitrate). The concept was there, however, it absolutely was not until 1993 that high brightness of blue LED lighting was possible due to the work of a man named Shuji Nakamura from the Nicha Corporation.
White Leds can be created in more than one way. For example: As I mentioned, most LED white lights are based on 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.
