LED TV Facts and Buying Guide


"LED TVs" in reality are LCD TVs but are called so due to LED back
lighting technology used in them. Samsung a leading manufacturer of
consumer electronics, have been asked to explicitly indicate in their
marketing advertisements that LED TVs they are selling are actually not
pure LED but are LCD TVs which are equipped with LED technology.


In
technical terms this means that LED TVs being sold are actually TVs
with LED lighting technology, which depending upon the mechanism can be
backlit or edgelit. In backlit LED TVs there is a panel of LEDs just at
the back side of main LCD screen which is programmed to produce less or
more light depending upon the mechanism to enhance the image quality on
the LCD screen. Edgelit TVs have a mechanism where LED's are installed
on the edges which then point light onto the required areas on the
screen. This also allows the LCD TVs to be made slimmer than before.


The
LED LCDs are upto third slimmer than pure LCDs because of the very
small LED size as compared to the CCFL (Cold Cathode Fluroescent Lamp)
which are made use of in the LCD TVs. LED LCD TVs are capable of
creating more vivid images along with a vastly superior color and
contrast spectrum. The viewing angles have also seen improvement and can
now compete with those, generated by Plasma TVs.


Though these
factors have immense importance in making the overall performance of LED
LCD TVs superior, yet the major argument point used in the selling of
these TVs is its reduced power consumption. Edge lit LEDs consume about
40 % less power as compared to LCD TVs because the mercury less LEDs
used in former uses very less electricity to light up.


Many
manufacturers also add many environmentally friendly and power saving
mechanisms to these LED, so this may result in your electricity bills
and carbon footprints getting reduced.


A large number of new LED
TV ranges have been launched in the market recently. Samsung has
introduced super slimline models which are less than 1" in thickness,
Sony has introduced a individually controlled LED panel which is
backlit, Toshiba's has brought out new LED backlit mechanism with 240
KHz display panel, LG has jumped in with 240 KHz TruMotion LED backlit
TV range. Sharp has also introduced an Ultra Bright LED system.


With
so much of variations and models available for LED TVs it is good to do
in-depth research and then go for the model and brand which suits your
requirements and budget too.
