In the past few years, a new type of LCD TV has appeared that has changed the landscape of the flat screen market. It is being called a LED TV but it only uses LEDs for backlighting. It is not the same as a display that uses them as the primary display element. This new type still has many benefits over conventional flat screens, including better picture quality and reduced power usage. The LEDs can be positioned at the back of the screen or along its edges. Edge lighting allows the screen to be much thinner than other flat screens, as shown by the current models which are only one inch thick.

The flat screen market is filled with confusing acronyms. Even today, many people have no idea what LCD and LED stand for or why they are different. A liquid crystal display (LCD) has many tiny squares that act as shutters to control the amount of light that passes through them. A light emitting diode (LED) is a tiny, plastic light bulb that has no filament, produces no heat, and lasts for a very long time. There is also confusion about what exactly is a LED TV, and this has occurred because some manufacturers are using the term to sell what are essentially LCD TVs.

Scientists have yet to find a way to shrink the LED down to a size where it can be used in small displays. For now, they are only used in very large displays, like the scoreboards at stadiums. The only thing that buyers need to know is that a LED TV sold in a retail store is actually a LCD TV with a different type of backlighting. The real ones have no need for backlighting because the LEDs generate their own light. Despite this, an LED TV is generally better than the conventional models that use fluorescent tubes for backlighting.

One of the most noticeable benefits of a LED TV is the deeper black it can show. A conventional model has continuous light leakage because it uses fluorescent tubes that are always on. This results in a dark gray color when the screen is suppose to be completely black. It is one of the most annoying problems with viewing an LCD and it a main reason why many people choose a plasma screen instead. A LED TV can adjust the brightness of all or part of its backlighting to better suit the picture, however, current models can only do so in large blocks. This means that the borders between light and dark colors may not always be sharp, especially if the picture has a lot of detail.

The color of the backlighting is an important feature to consider. LED TV models that use colored light have superior picture quality to those that use white light. The model must use colored LEDs instead of white LEDs or fluorescent tubes. Colored backlighting is often referred to as RGB LED backlighting because RGB is an acronym for the three primary colors. This method represents the cutting edge of flat screen technology and buyers should expect to a premium price for it. Until a real LED TV is developed some time in the future, flat screens that use this technology will be the ones that everyone will want to own.

A LED TV is also a good choice for people who are concern about the environment. Conventional flat screens are often criticized for the amount of electricity they use. Most of this is used by the fluorescent tubes that provide the backlighting. LEDs are very efficient and uses much less power to provide the same amount of backlighting. Another factor is the small amount of mercury inside each fluorescent tube. Mercury is highly toxic but LEDs have no toxic risk. A regular LCD TV pollute the environment if it is not recycled properly.
