LED TVs - Cutting Edge Tech with Only a Few Glitches

Some of the biggest trends in the television market today are LED-backlit TVs, more commonly known as LED TVs. These TVs still use the standard display system, but instead of using cathodes to light up the screen, these TVs use LEDs (light emitting diodes) to achieve the same effects. There are, as with any new technology, both advantages and disadvantages to this new approach.

 One of the biggest pros of the LED TV system is the fact that using their backlighting reduces power consumption exponentially compared to the use of cathode lighting. In addition to that very noticeably change, the use of LED also allows for a thinner television and better heat dissipation. To put it quite simply, the use of the LED TV results in thinner, better-looking and more energy efficient televisions than ever before.


 Of course, like any cutting edge technology, LED TVs also have their downsides. One of the most prominent problems with LED TVs is flicker. If the backlight isn't turned up quite high enough, the television will display what is known as the "flicker effect," which, while very hard to perceive with the naked eye, will still cause eye strain, especially over time; however, this problem is usually relatively easy to fix by just turning up the brightness on the panel, negating any flickering effect that may take place.

 Another problem that exists in any line of LCD TVs, but seems to be more prevalent when it comes to LED TVs, is dead pixels. A pixel is dead when it does not display any colour and this can happen in individuals or clusters. There is, however, an important distinction to be made between "dead" pixels and "stuck" pixels, which can commonly appear very similar. The difference is that while dead pixels are not repairable by the consumer, stuck pixels can very easily be repaired by running specific videos or pieces of software on the television to "unstick" the pixel.

 Neither of these problems is not exactly common, so most people should not have to worry about dealing with them. Instead, consumers should focus on the features of the televisions that are guaranteed, such as the hertz rating of the television or the viewing angles. Most television manufacturers have a relatively decent return or repair policy, and if they do not, one must be sure to check the policy that the store (whether brick-and-mortar or online) has in place for these sorts of things.
