LED TVs have redefined the consumer
viewing experience – so much so, that no other TV can now make the cut!
For the average TV viewer, an LCD TV is a
big innovation in television technology, topped only by the LED TV. Popular
perception dictates that LED TVs are more expensive, but well worth their price
tag, since they offer crisp, deep colour and sharper resolution. But there is
much more to LED TVs than (literally) meets the eye. Here are a few things to
know about LED TVs.
An LED TV is an improved LCD TV. Most people think that there is a very significant difference
between the two types of TVs – in simple terms, an LED TV is not a radically
different technology. It is actually an LCD TV that uses backlit LEDs instead
of the usual cathode fluorescent lights (CFLs) screens, on receiving
electricity. Thus, they are different from plasma TVs or OLED technology, where
each pixel on the screen is an independent light source.
LED TVs come in two configurations. Some LED TVs have an entire panel of LEDs behind the screen – these
are known as ‘full array’ LEDs. However, some people prefer thinner LED TVs, in
which case, an entire array of LEDs cannot be put behind the screen. Hence, the
LEDs are arranged to line the screen along its perimeter, so that the light is
concentrated inward in the middle of the television. These TVs are known as
edge-lit TVs. But this latter kind of LED TV is known to show brighter edges
than the rest of the screen.
Some LEDs offer differential lighting. Also known as ‘local dimming’, this feature is unique to LED TVs
with full array backlighting where the LEDs independently dim or light up areas
of the screen depending on the screen colours and contrast. Hence, scenes
featuring black and two other colours, for example, will have dimming in the
black portions and lighting in the other portions. This gives unparalleled
depth of colour and perception, making the picture alive.
LED TVs use less power than standard CFL
screens. LED TVs will result in lower power bills
for you, since LEDs are more efficient that CFLs. Most LED TVs today consume
about 100W of power, as opposed to about 111W for CFL screen TVs and
significantly lower than plasma TVs.
