Understanding LED TV Technology



If you have looked at all the fabulous photos of an LED TV from
this year's catalogues and are set to buy one for yourself, it will
really be helpful in your purchase if you know a few facts about the
technology first. The LED TV had a great reception at this year's CES
Trade Show and Samsung was the first one to actually have brought the
technology into the market with its Samsung 7000 television set range.


Simply
put an LED TV is actually an LCD television which incorporates an
additional technology. LEDs are light emitting diodes which are an
efficient light source and while previously other methods of lighting up
the LCD screen were used such as fluorescent tubes, now the LEDs are
utilized to light up the LCD display.


While fluorescent tubes
provide light, they have a few drawbacks. They take up more space and
are heavy in weight. Also they do not provide sufficient color quality
because the blacks displayed are not true blacks and this reduces the
vibrancy of all other colors. This is basically why the LED technology
came along - so they could provide a lighting source that can show the
purest blacks and whites.


At the present there are a couple of LED
TVs available to the consumer. One of them is back-lit model which
allows the LCD display to be lit up by back lighting through a number of
LEDs placed behind the television panel. The other one is the break
through edge lit version which uses LEDs as a light source positioned
around the edges of the television screen. Using LEDs as back lights
requires a lot of space in the back of the television set, making the
LED TV thicker in size. The edge lit LED display however, requires less
back panel space and hence the designs are much slimmer and sleek.


Another
useful feature of the edge lit LED television is that it consumes less
energy which is not only good for the environment but also saves you on
the monthly electric bill. So the first thing you will need to do when
buying the LED TV is to figure out whether you want it back lit or edge
lit, since the rear lit ones will be more expensive to buy. There are
also a number of accessory options for the LED television sets.


The
television screen can be used as an interface for one's personal
computer. This makes for a television set that can play all your
favorite items from your computer which includes live streaming from any
internet website and watching online movies. You can even watch your
home videos that have been saved on the computer. LED television sets
also come with a USB port which can be used to view the material on your
USB flash drive and view movies, videos or pictures.


Other
accessories that can be added to the LED TV are Blu-Ray players,
satellite dish receivers and even the latest gaming consoles. This is
owing to the HDMI ports which eliminate the need for cables (both A/V
and coaxial) and adapters. You can also buy a wall mount kit with your
LED if you are interested in mounting the set on a wall in your home.
LED TV sets are much lighter than the previous LCD TVs and they are much
easier to hang on walls. This is especially true for the edge lit LED
display television which is much lighter and thinner and better able to
be mounted.
