Gone are the days when TV could have been easily bought. Now it
has become as complicated as it is to choose the right data plan for your
mobile phone. Before the flat TV screens came into the market, the only
consideration for buying a cathode ray tube(CRT) TV was how much space you have
in your home and how much huge do you want the TV to be. Quality did matter but
the most important was how many inches you could get for how much money.
When searching for the latest TVs, the same points are
considered. There was always a plasma TV versus LCD Tv until LED Tv entered the
market. Thought it has made its position in the market still, people are
confused about what it really is. It is actually a different form of LCD Tv
which uses LEDs as its light source.
All these TVs are backlit as LCD doesn’t produce the light of
its own. So, for producing an image on a panel display, the pixels are backlit
by some other lighting source. Currently, you’ll see CCFL technology is being
used as a backlight source. This delivers good brightness, great color, and
decent contrast. But there are not so great blacks. But the LED TVs which use
CCFL technology, deliver much better black with greater contrast and brighter
colors. Contrast is measured by the darkest lit screen area to the area which
is the brightest in order to give a contrast ratio.
Spotting the difference
If you thought choosing the Tv just got easier then there are
numerous LED options too available in the market. You will find the edge-lit
LED and full matrix LED Tv. There is a slight difference though. But it's very
important for you to see what the brands these days are using as a backlight
choice preference. This is what really matters.
Is it actually an LED TV?
A true-blue LED TV is those huge screens which you usually come
across in rock venues, Grand Prix events, and outdoor stadiums. These huge
screens consist of thousands of LED lights which are extremely bright. As the
LEDs used in these are chunky and large to be used in a TV, they are best used
for light sourcing the backlight of LCD crystals. You can call it a mini
version of the large screens you come across, using the same backlight and
technology.
