LED backlighting has grown to become a key feature on outdoor digital displays. Today, many advertising companies and institutions are using LED backlighting in implementing their outdoor digital signs. Apart from outdoor signage, LED backlighting is also used in desktop screens, notebooks and mobile phone LED screens.

The key reason why LED screens and LED backlighting are dominating outdoor signage is because, they offer a far much better audience experience. Consequently, it has grown to become the hottest form of digital signage that is being touted in the market today. In order to understand this phenomenon better it is good to evaluate the key features that come with LED screens, which make them ideal for outdoor displays.

LED lighting power supplies are rapidly gaining market in the signage and advertising field. In the last two decades, there has been a proliferation of commercial LED displays as an advertising tool. Their fast uptake in the market can be attributed to various benefits, which they provide. They are ...
... also very advantageous compared to conventional LCD displays. However, they are more expensive than LCD displays.

LED backlighting and displays are basically something special. This can easily be deduced from various features and advantages, which they provide over their peers. Firstly, LED backlighting and lighting power supplies last for a very long time. Longevity is a key feature of LED backlighting and outdoor signs.

When compared with other display technologies like plasma and LCD, LED screens are superior. They provide excellent display experience that is very attractive. Additionally, they can provide reliable display for more than ten years. This dwarfs the life span of all other display technologies. LED drivers and backlighting are ideal for a long-term project. When compared with LCD screens, LED backlighting holds the edge. Normal LCD screens usually fail within four years, when used for backlighting. Enclosed LED backlighting and displays can last up to a minimum of about seven years at full brightness.

Another advantageous feature that comes with LED backlighting is the fact that, it is sunlight readable. Display screens that are deployed directly against bright sunlight are hard to read. The light usually washes out images making the whole signage appear shabby, and unreadable. In order to deal with this problem, you need to consider the nits of the screen. The nits of LED screens vary from two thousand to four thousand nits. This is just super while compared to the 600 nits of LCD screens. Clearly, LEDs are better with their sharper and clearer images.

LED backlighting and screens can withstand extreme outdoor operating temperatures. This is another reason that makes them ideal for signage. The internal component of LED screens can deal with extreme temperatures. Consequently, they are far much better than their peers in the industry. This feature also applies to LED drivers and other LED lighting supplies. However, although they can easily cope with extreme temperatures, it is advisable to construct an enclosure, in order to provide climate control. From the above examples, it is clear to see that, the high price tag that comes with LED backlighting is justifiable, and it is worth every penny.
