The X-Factor of LED TVs Revealed
By Darco | February 17, 2010
When a new technology is introduced in the market, it’s only natural that one tends to follow the crowd. But while those with bulging pockets can afford to try out every latest gadget (and shove it into the deep recesses of the webby wardrobe in case it turns out to be tacky), most of us are left goggling with a pang day in and day out. When LED TVs were first introduced, the lucky few who could afford them made sure that the rest of us were left struggling hard to save for one too. But are LED TVs actually worth it? What do they actually have that warrants the extra cost, not to mention the hype?
Simply said, LED TVs are LCD TVs with an LED backlight system. That is, the fluorescent lights which are traditionally used to illuminate LCD televisions are replaced by LEDs that are either arranged behind the panel, covering the entire surface or just on the edges. ‘Big deal. How can placing just a few peanut LEDs behind the screens incite an apparent impact in the picture quality?’ Is that what you’re thinking? Well, here’s how. The power of the LEDs behind the panel cannot be under estimated.
Backlight bleed seems to be following LCD TVs persistently. The bleeding mainly occurs at the top and bottom portions of the display due to the placement of the CCFL lamp. And as we know it, LCD TVs struggle when it comes to rendering deep blacks and neutral colours. And when viewed form an angle, things get worse. For LED TVs, overcoming these problems is a cakewalk.
LEDs can be dimmed or brightened according to the scene being played, the result of which blacks are blacker than ever and whites are whiter than ever. The most appealing aspect of these tellies is however, their looks. The elimination of the conventional light source makes LED TVs slimmer and more appealing, and it is needless to say that they have quite a lot of takers just for the looks. Furthermore, these svelte TVs save you the power-bill swoon, for the LED backlights consume much less power than CCFL lights. It’s said that LED TVs consume 40% lesser power than that of LED TVs. Certain manufacturers like Samsung make use of mercury-free LED lights that emit less CO2.
So, now that you know all about these slim stunners that the condescending neighbour is trumpeting about, should you actually buy one, given the high cost? Why not? For that ultimate entertainment experience that has got to be seen to be believed, the extra cost is definitely worth it.
