How the LED TV Lighting Works?


Because of the excellent movie experience due to its high
definition images, LED TV is what everyone wants to have in their homes.
Everybody having the LED TV is saying that it is the perfect television
that they've got, but did you bother know why? What makes LED TV rise
among other TV? Let us all explore the wonders behind the LED TV
lighting making it the number one television.


The LED TV is
actually a LCD TV that uses Light Emitting Diode backlighting technology
rather than the ordinary lighting used by the LCD TV which is the
fluorescent lights. The latest LED technology in every high definition
TV marked a buzz. LED HDTV is known for its thinness and stunning real
like images. The great advantage of the LED HDTV is the combination of
the benefits you can get from Plasma TV and LCD TV using fluorescent
lighting. We have known the downfall of LCD TV using a fluorescent
lighting which it cannot project a deep black image and the plasma TV
cannot bring bright images. But LED HDTV projects deep black similar to
plasma TV and a brightness more than the LCD TV.


In the LED
technology there is what we call EDGE LEDs with local dimming and Full
LED Slim Lighting. Are you amazed by the slim television or mobile
phones that most of your neighbor owns? With that impression then you
are impress by the lights being used to light up those products. LEDs
are widely known because of its cutting edge technology for being slim
light emitting diodes. There are two basic components of EDGE LED; first
is the light guide plate which is like a thin plastic sheet and the
second is an LED module made up with a row of small white diodes used
for lighting. What made up an HDTV are four rows of LED modules that are
laid out on the top, bottom, right and left of the television panel. To
avoid shading and misrepresentation of the colors being displayed, the
lights are evenly distributed.


A bright glare is one problem that
sometimes arouse when using Edge LED. There are visible reflections that
can be detected on laptop computers, televisions or even on mobile
phones, so the EDGE LED with local dimming has discovered. Through this
local dimming you can already control the level of lighting used. Glare
can disturb your eyes even with perfect images, with local dimming you
can tone down the LED backlights. One advantage of LED is that it can
conserve more energy; this is because of the electroluminescent process.
This is a process of creating light simultaneously.


On the other
hand the Full LED slim lighting which is now mostly used by HDTV allows
you to bring a cinematic experience in your home because of its better
image resolution, crisp quality of color and the perfect ratio of gamma
and luminance.


If you are wondering why we have to know about this
things, well simple because LED TV are more costly than other TV then
you better have to choose an LED TV that suits your home. LG
