One of the most effective sources of light nowadays is the LED or Light Emitting Diode. It is also the very same technology, or device rather, that is used in LED displays. Examples of things that make full use of LED displays are remote controls, traffic lights, store signs, billboards, just to name a few.
What’s surprising is the fact that LED’s supposed application is for illumination and not for display. LED displays usually consist of LED panels and that panels consist of a lot of LEDs themselves. There are mainly two types of LED panels being sold in the market. These are the Surface Mounted Device or the SMD and the conventional LED Panel. The latter are mainly used for display screens outdoors, most of them usually being large displays. They are more common and that in this type of LED, the clusters of LEDS group to form square shaped pixels for displaying purposes. While indoor LED displays mainly make use of the former, the SMD LED. This technology makes use of LEDs that are colored red, green and blue which are used for lighting and illumination. The pixels formed from such projections are smaller than a pinhead. This causes problems when it comes to viewing from long distances, which make SMD technology more optimal for indoor application
LEDs have many applications aside from TVs. These light emitted diodes are often considered better when compared to other light emitted devices and sources. The main reason is how they work. These diodes are typically made out of semiconductor chips, being surrounded by transparent plastic cases. The cases then allow light to pass through it. After so, electrons then start flowing because of its chemical nature. The resulting color or image then is mainly dependent on the semiconductor material chosen for the diode.

LEDs are most preferred nowadays because of the fact that it does not waste energy. In contrast to most traditional light sources which produce a lot of heat and waste energy, LEDs are quite the contrary. For this very reason, traffic lights and other devices make use of LED technology.
At first, LED displays weren’t considered to be good considering that they were monochromatic, meaning only having a single color. This is due to the fact that not a single blue light LED that was efficient had been invented yet. Ever since it hit the market, LED technology has grown and due to this, its inventors were given their respective awards during the 29th Engineering Exposition held in Anaheim, California. Though, the technology is relatively new, only being introduced about two decades ago. It isn’t really that surprising that LED displays have slowly taken over and become the staple display technology being used nowadays.
