ERALED display is a fast growing energy saving, high tech green products which taking place of the old traditional products rapidly nowadays. You can ignore the existence of the LED display. However, the LED display will never ignore you! The LED display is appearing in every corner of the world and touching with us every second. We are living and touching with the LED display every second even we don't know it is called "LED display".

LED Display is modernizing our life, our town, our city. It's so fashion that if an important events were held without the LED display. It is called "out", "failed", etc.

Every downtown, street, shop, school, church, window was also installed the giant LED display now!

LED display is the basic necessary equipment for every country's Central Television station. Even every small town's TV station has a huge LED display now!

LED display is also the basic necessary equipment for every important sports stadium. No matter NBA, or football World Cup LED display is always the necessary equipment. Even for some sports which you may never care also equipped with the LED display, for example: Badminton, Tennis, Soccer,Volleyball,Goalball,Softball,Speedball,Handball,Rugby,Aikido,Skiing,Wrestling,Archery,Beagling,Swimming,Cue sports,Dancing,Fencing,Fishing,Golf,Grappling,Gymnastics,Hockey,Hurling,Judo,Racing,Tennis,Trampolining, etc.

Even the more and more taxi tops were equipped with the LED display now!

However, what is LED display in end?

A LED display is a video display which uses light-emitting diodes. An LED panel is a small display, or a component of a larger display or Display. They are typically used outdoors in store signs and billboards, and in recent years have also become commonly used in destination signs on public transport vehicles. LED panels are sometimes used as form of lighting, for the purpose of general illumination, task lighting, or even stage lighting rather than display.

Types of LED display

There are two types of LED panels: conventional (using discrete LEDs) and surface-mounted device (SMD) panels. Most outdoor Displays and some indoor Displays are built around discrete LEDs, also known as individually mounted LEDs. A cluster of red, green, and blue diodes is driven together to form a full-color pixel, usually square in shape. These pixels are spaced evenly apart and are measured from center to center for absolute pixel resolution. The largest LED Display in the world is over 1,500 foot (457.2 m) long and is located in Las Vegas, Nevada covering the Fremont Street Experience. The largest LED television in the world, the Center Hung Video Display at Cowboys Stadium, is 160 by 72 feet (49 by 22 m), 11,520-square-foot (1,070 m2).

Most indoor Displays on the market are built using SMD technology—a trend that is now extending to the outdoor market. An SMD pixel consists of red, green, and blue diodes mounted on a chipset, which is then mounted on the driver PC board. The individual diodes are smaller than a pinhead and are set very close together. The difference is that the maximum viewing distance is reduced by 25% from the discrete diode Display with the same resolution.

Indoor use generally requires a Display that is based on SMD technology and has a minimum brightness of 600 candelas per square meter (cd/m², sometimes informally called nits). This will usually be more than sufficient for corporate and retail applications, but under high ambient-brightness conditions, higher brightness may be required for visibility. Fashion and auto shows are two examples of high-brightness stage lighting that may require higher LED brightness. Conversely, when a Display may appear in a shot on a television studio set, the requirement will often be for lower brightness levels with lower color temperatures (common displays have a white point of 6500 to 9000 K, which is much bluer than the common lighting on a television production set).

For outdoor use, at least 2,000 cd/m² is required for most situations, whereas higher-brightness types of up to 5,000 cd/m² cope even better with direct sunlight on the Display. (The brightness of LED panels can be reduced from the designed maximum, if required.)

Suitable locations for large display panels are identified by factors such as line of sight, local authority planning requirements (if the installation is to become semi-permanent), vehicular access (trucks carrying the Display, truck-mounted Displays, or cranes), cable runs for power and video (accounting for both distance and health and safety requirements), power, suitability of the ground for the location of the Display (if there are no pipes, shallow drains, caves, or tunnels that may not be able to support heavy loads), and overhead obstructions.
