What is an LED Screen

Find the answer to the frequently asked LED Lights related question: What is an LED Screen?
The LED screen is a large display screen which is backlit by LED lights. LED stands for "Light Emitting Diode." It's a semi-conductor which emits light as electrons travel through it. From the outside, it almost appears to be a small lamp, and yet it functions completely differently. The light emitted depends on electrons as they flow between cathode and anode within the chip. Also, the materials utilized will determine the color of the visual emission.

Story of the Pixels

In the LED screen, when you put several LEDs together, it forms several pixels. A pixel is the "dot light" found on every LED giant screen. This dot can be formed by one LED or several LEDs. How many LEDs will depend on the features and the dimensions of the screen. On a full-color screen, a pixel is formed by the primary LED colors (green, red and blue), which together, form white.

Variety of Sizes in LED Screens
Each square yard on the LED screen can contain between 1,024 and 9,216 pixels, depending on the model. The number of pixels will vary depending on pixel pitch (The pitch defines the distance between two or more pixels). LED screens are available in a number of different sizes, models and makes, from Standard Definition to High Definition.

Costs of LED Screens

There are so many variables in the cost of an LED screen that asking how much one costs is like asking what the price is to buy a car. Here are five variables that will help shape the cost of the screen:

1) Size. Larger screens naturally cost more than larger ones.
2) Resolution. The higher the resolution, the clearer the picture, but you'll have to pay a bit more for the better picture.
3) Reliability. Premium makers' screens will cost more than the no-name version. That's because the big names have a reputation for reliability. Along these same lines, beware of ordering online from some just-established Asian company without a proven reputation.
4) The Dealer. Some dealers offer better deals than others, even on the exact same screen. Fortunately, the Internet makes it easy to price-compare.
5) Customer Service. Believe it or not, the price of your LED screen is connected with the customer service available. Often times- too often, really- the cheap models come with next to no customer service. Part of the price of the higher-tagged screens covers this superior customer service.
6) Quality of the Warranty. The type of warranty that a piece of electronics equipment has usually impacts the costs. It's better, however, to spend a bit more on a screen with a good warranty than to get a bargain price on one with almost no warranty.

The Verdict on LED Screens

LED screens are perfect tools, especially for those who need to make presentations. The LED technology makes it possible to produce slide shows and presentations that are crisp, clear and easily seen from a long distance. It's easy to find them in any size that you need.
