WHAT IS LED DISPLAY FACTS?
LED is short for Light Emitting Diode. An LED emits light as a result of electric luminescence. It is also known as “cold light” as, unlike with old-fashioned incandescent bulbs, the light is not produced by heating a metal filament. The diode, on the other hand, emits light when flowing through two specially coated silicon semiconductors. It is one of the most energy-efficient and power-saving ways to produce light.Get more news about

An LED consists of solid materials without movable parts and is often moulded into transparent plastic. This ensures high durability. When an LED is on, it emits almost zero heat. This reduces the problem of cooling the electronic parts.
The first LED was created by Russian inventor Oleg Losev in 1927. For many years, it was only possible to produce infrared, red and yellow LEDs. These diodes were found in everything from remote controls to clock radios.
It was not until 1994 that Japanese scientist Shuji Nakamura was able to demonstrate an efficient blue LED. White and green LEDs soon followed, laying the foundation for the LED revolution we have seen in lighting and display technology.An LED display consists of many closely-spaced LEDs. By varying the brightness of each LED, the diodes jointly form an image on the display.
To create a bright colour image, the principles of additive colour mixing are used, whereby new colours are created by mixing light in different colours. An LED display consists of red, green and blue LEDs mounted in a fixed pattern. These three colours combine to form a pixel. By adjusting the intensity of the diodes, billions of colours can be formed. When you look at the LED screen from a certain distance, the array of coloured pixels are seen as an image.RGB is short for Red, Green and Blue. It is a colour scheme that exploits the fact that all visible colours can be mixed from these three basic colours. It is used in almost all types of displays, including LED displays.
MD means Surface Mount Device. These are electronic components that are surface mounted directly on a printed circuit board – and not as previously by soldering the metal pin on the underside of the circuit board.
In LED display technology, the SMD concept is used a little differently. An SMD display is an LED display where the red, green and blue diodes are potted in a small plastic encapsulation which is surface mounted on the printed circuit boards of the display. When the diodes are encapsulated in this way, they take up a lot less space, making it possible to produce displays with less spacing between the diodes and higher resolution.
