Introduction of LED TV Types

Today’s HD TVs benefit from several decades of extensive research and technology. Many HD TVs are becoming thinner and often include many interactive features such as internet connectivity. Most consumers are big on HD quality display and multimedia playback amongst other features. If you consider yourself to be the kind of person who researches and reviews products before making a buying decision, you know that the options of HD TVs available are so many. Today it’s easy to be confused with so many different terminologies and technologies. LED HD TV is one of such technologies/terminologies.

Although fairly new and advertised more, LED TV is really an LCD HD TV with a different backlighting system. Aside from environmentally friendliness and energy efficiency, one of the key benefits of LED TVs is the display thinness and weight. This means that LED TVs are thinner and often lighter than other HD TVs are making them ideal for wall mounting as well as small space options.

Because of the lighting technology of light-emitting diodes (LED), which LED TVs use, the back panel of the HD TV is paneled with LED lights which are thinner than LCD’s CCFL lighting. There are two types of LED backlighting, the edge-lit and full-light technologies. Full Light is used for most large displays and produces a more solid viewing experience. Edge-lit relies on several LEDs placed in four places behind the panel display. Edge-lit LED TV allows the sizes of the LED TV to be reduced that cause the thinner HD TVs.

Although this is an essential feature for some consumers, the thinner “edge-lit” LED TVs do have some downsides. For example, there is no unified design that can be used for edge-lit LED TVs, which means it is not possible to find a major contract in image quality between different manufacturer models. Also while displaying darker or black images, the sides of the LED TV screen may appear lighter, this can create a different viewing experience from that of full-light LED TV especially in low light settings.
Full-light LED TVs rely on local dimming; a feature that automatically adjusts the LED backlights to create richer black colors as well brightening essential colors on the LED TV. This is similar to the way that some plasma HD TVs automatically calibrate and adjust their settings to the images being displayed.

Though most people may not take notice of the major differences between edge-lit and full-light LED TVs, anyone who is looking to purchase an LED HD TV should put the essential facts into consideration before making a buying decision.
