Take a look on types of LED technology

In LED display we use light-emitting diodes for displaying a picture. As compare of a normal display an LED display is a small display or a component of that large display. They are typically used in store boards or outside the wall of the building for advertisement purpose, and now it is using in the destination boards of the public transport vehicles. And now this technology is introducing in our TVs. Now we can see the TVs with a new experience.

There are two types of LED panels; one is using discrete LEDs and other one is surface mounted device panels. Most of outdoor screens and some indoor screens are using discrete LED’s. We also know it as individually mounted LEDs. To create a full color pixel we use 3 different colors diodes together, usually square in shape. The distance between the pixels is measured from center to center for getting absolute pixel resolution. The biggest LED display is located in Las Vegas in the world which is 1,500 foot long. And the biggest LED television is in Cowboys Stadium in the world which is 72 square foot.

Most indoor screens in the market build using SMD technology means surface mounted device technology. In this technology we use red, green and blue diodes on a chipset for creating a SMD pixel. This chipset is then mounted on a driver PC board. These individual diodes are smaller than a pinhead and therefore set closer to each other. The main difference is that the maximum viewing distance is reduced by 25% as compare the discrete diode screen with same resolution.

To use this technology for indoor like in TV sets it requires SMD technology and therefore a minimum brightness of 600 candles per square meter. This will be more than sufficient for corporate and retail application, but higher brightness may be required under high ambient brightness conditions for visibility.

Auto shows and Fashion world are the two main example of high brightness stage lighting. They require more brightness therefore they use higher LED brightness. If you have outdoor use then at least 2000 sc/square meter is required for most situations, where the sunlight comes directly on the screen. The brightness of the LED panels can be reduced with a complex design if required.

These are all about the types of the LED technology and where it is useful. You have to know about it because now it is using in TV sets also. So before purchase a LED TV you need to read a review.
