LED TVs have become the ‘in thing’ in the television technology since its introduction, and it has no lack of enthusiasts who go all out for viewing perfection of the flat panel. The people who would most probably like to consider buying a LED TV would be those who spend a lot of their time watching TV programs or shows, movies and animations.
Equally enthusiastic potential LED TV owners are those who love to play loads of video games for lengthy periods of time. Not forgotten are those who enjoy watching fast moving videos such as sports. LED TVs would also be appealing to those who tend to spend long hours watching television during the day in spaces without curtains, as LED TVs can resist glare. With a list of advantages blowing the trumpet, and possibly a high price being the only disadvantage, it comes as no surprise why people are magnetized to this new range of television.
When consumers have decided that LED TVs are for them, the question of what needs to be considered arises in their mind before they decide to part with their hard-earned money. There are a number of pointers potential buyers need to think through when they make their LED TV purchase, as they would need to allocate additional budget for accessories to complement their flat panel.
One of the basic things consumers need to decide when purchasing their LED TV is whether to get a RGB Dynamic LED-lit LCD TV or a Edge-LED TV. A LED-lit LCD TV generally contains about a thousand LEDs or less. This means that the LEDs must be dimmed as a whole, as it costs way too much to control each diode independently. As a result of this, when a cluster of LEDs are dimmed, a continuing part of a scene on the television that should actually be bright, might turn dark. If the dimming effect is lessened, the blacks might lose its depth compared to the other sections of the image that are away from brighter images. The RGB Dynamic LED method of illuminating the LCD screen, also known as local dimming, creates precise areas of darkness on the screen. Samsung 8500, the LG LH90, the Toshiba SV670, and the Vizio VF551XVT are among the LED TVs that utilize the local dimming method.
On the other hand, the Edge-LED technique makes it possible for exceptionally slim LED TV panels to be made. A unique panel that produces a standard color variety across the display screen distributes light throughout the screen. The edge-LED technology is available in the Samsung B8000 models. The very reason the edge-LED TV gets its name is attributed to the fact that the light emitting diodes are assembled along the edge of the display, permitting manufactures the pleasure of creating a pleasingly thin design. Apart from that, both back-lit and edge-lit LEDs use an almost equal amount of LEDs to light the LCD screen. Thus, they are actually not very much different. So, at the end of the day, it is really up to the consumers what they are willing to forgo, and what they want. Having knowledge about the LED TV and what goes with it will help them make an informed decision.
