LED Screens Combine Quality With Economy


Light emitting diode or LED screens are just one of the devices in common use for creating large and impressive displays today. To these may be added two earlier types of monitor that utilise liquid crystal display (LCD) and plasma technology respectively. Alternative methods still commonly employed to create large displays utilise big screens that either reflect or transmit images projected, respectively, from in front of or behind the screen. LED screens utilise the newest technology, combining high quality with exceptionally low power consumption.

Like the alternative LCD panels, LED screens may also be interconnected in order to create wall-sized displays when required. Although a little more expensive to purchase, they are widely acknowledged as offering the brightest and clearest display under all conditions in addition to their competitive running cost. LED screens prove to be equally effective whether used indoors or out, a fact that makes them ideally suited for use in animated billboard advertising,

LED screens create their displays from an array of thousands of individual pixels, each of which is made up of a cluster of red, green and blue diodes, each smaller than a pinhead. The distance between adjacent pixels is used as a measure of the screen resolution. The LED screens are built in one of two formats. Conventional displays utilise discrete or individually mounted LEDs and are best suited to outdoor use. The second format, known as SMD (Surface Mounted Device) panels are the most commonly used in screens designed for indoor use.

Key to the performance of LED screens, particularly under the ambient lighting conditions that are encountered in outdoor venues, is the brightness achieved by the diodes. Diodes may be engineered to produce differing levels of brightness, normally measured in candelas. LED screens used indoors for retail purposes or home entertainment operate at between 600 and 1000 candelas while an average brightness of 2000 candelas is generally needed for outdoor displays although units offering up to 5000 candelas are available.
