An LED television is a hot selling product in the market. If you are planning to buy it, then you must gain a good amount of knowledge about its specifications and working. The more you are informed, the more efficient your decision will be.
An LED TV is not a unique type of TV
A lot of people want to buy an LED television thinking that it is special kind of television that will add fun and pleasure to their viewing experience. Many professionals at the dealer would market such television set in a grand way so as to convince them.
The truth is that, LED television is simply an LCD TV that is illuminated with light emitting diodes in place of standard cold cathode fluorescent lights. This television is based on a transmissive technology where each and every pixel has to be lit from behind.
Generally, in LED televisions, there are two LED backlight configurations. This configuration resembles similar to Samsung LN-T4681F, where backlit is referred as a “complete array” of LEDs at the backside of the LCD and across the rear end of the panel. This design looks a lot thinner than other television sets and eliminates extra layer of LEDs by moving it to the sides of the display.
Due to this type of backlighting, the LEDs are attached to all 4 edges of the television and light is projected at the interior of the television via “lightguides.” Due to this reason, it makes these televisions as “edge-lit” LED. They are the most common types of LED’s that are available on the market at present.
Local dimming LED backlights can be turned off or dim individually as required. All present-day LED- LCDs comes with full-array “LED backlighting” that are placed at the rear end of the television. This feature allows to reduce or increase the intensity of the backlight independently. In this way, you can view dark or bright picture.
Edge-lit television sets are quite thin but lacks uniformity
One of the benefits of an edge-lit LED backlighting method is that you will find thinner televisions on the market. However, the not so good part of backlighting feature is that it is not uniform. This means that if a white image is put up, then the outer edges of the device screen will look brighter. On putting up an “all-black image”, the screen edges appear lighter or grayer.
LED backlighting has no impact on LCD’s poor off-angle viewing
Unlike plasma, one of the major downsides to LCD television is that the quality of image degrades if you stand or move to the side or the device is kept too low or high based on the eye level. LED backlighting does not bring any change and actually make it worse.
LED backlighting is far more efficient when compared to normal fluorescent backlighting.
LED backlighting can help in lowering power usage. Some LED-backlit LCDs offer the most well-organized flat panels.
By knowing all these features, you can be sure that LED TVs are the best HDTV available on the market. It makes a wise decision to spend your money on this grand and latest technology. Its proper set up will get you the most outstanding viewing experience.
