An LED (light-emitting diode) television is actually a kind of LCD (liquid crystal display) television. The difference is that whereas an LCD television uses a fluorescent backlight to create an image, an LED television has a more sophisticated backlight system.
What's so special about LED televisions?
LED televisions are known for their stunning contrast and picture clarity because the lights powering an LED screen are individually arranged behind the screen avple. This type of picture arrangement is known as full LED or direct LED and it's the magic behind the incredible picture that you experience when you come across an LED.
Over the years LCD televisions experienced a reinassiance in picture quality and became LED televisions with better image resolution. An LED could then cast a picture to an audience by housing lights behind the screen or on the sides of the screen.
The latter system of installing lights along the four sides of an LED screen - known as a "light-guide"technology - became popular as engineers aimed to squeeze more HD into a thinner screen.
That said, although an edge-lit LED is now the most popular television on the market today, some critics complain that uniformity can drop in quality. This may be so but the sheer customizability of LED screens ensures that they will be sticking around for the long haul. One key feature of this customizability is known as local dimming, which allows LED owners to individually turn on or off portions of the screen's interwoven backlight system.
Where can LED televisions be used?
LEDs are actually best used in offices, schools or homes rather than outside. The problem with using a high-end television outside is that moisture, lighting and keeping the electronic components on the televisions from the abrasive rays of the sun can prove problematic.
LED televisions, like standard flat screens and LCD televisions, are designed to work within a narrow band of ambient temperature. If you live in overly frigid or warm climate, freezing or high humidity could cause the electronics in your LED television to malfunction.
Given that most LED televisions start at around $400, and that most LEDs are seen as the crown-jewel right now in the television industry, it may not be wise to subject that kind of technology to the wear and tear of hot summer weather.
In LCD televisions, for instance, the frigidness of February in some regions could actually negatively impact how the liquid crystals function; the same type of thing can happen with light-emitting diode technology.
You shouldn't worry about using your LED television in a normal office or home environments, however, as televisions today have in-built fans and heaters to keep the set performing just as well as when you purchased it.
