The so-called LED TV, is the LCD (liquid crystal) TV, that is to say, the use of LED as a backlight of LCD TV. In the past, LCD TV used cold cathode light source as its backlight. LCD TV has experienced the development of common backlight wide color gamut backlight LED backlight.
The so-called LED TV is LCD (liquid crystal) TV, which uses LED as the backlight.
in the past, LCD TV used cold cathode light as its backlight.
LCD TV has experienced the development of common backlight wide color gamut backlight LED backlight.

Which is better, LED TV or LCD TV??

.
the development of LED backlight has been carried out     Led liquid crystal TV has the following advantages:
LCD TV has the following advantages     1. Ultra thin: the thickness of traditional LCD TV is usually about 10cm.
LED backlight is more common in notebook computers, and its application in TV makes the thickness of LCD TV body have a thin leap.
.
LED backlight is widely used in notebook computers     2、 Environmental protection and energy saving: cclf cold cathode fluorescent lamp, the backlight used in traditional LCD TV, contains mercury which is harmful to human body.
although manufacturers are trying to reduce the mercury content in fluorescent tubes.
but completely mercury free fluorescent tubes will bring some new technical problems.
LED backlight does not contain mercury.
it is in line with the fashion of green environmental protection.
LED backlight is also very energy-saving.
L The internal driving voltage of ED is much lower than that of CCFL.
the power consumption and safety of ED are better than those of CCFL.
.
    3. Long service life: the rated service life (half bright) of different CCFL is between 8.
000 ~ 100000 hours.
in order to enhance the performance, the service life of CCFL backlight with improved design will be lower.
and the service life of LED backlight can be about twice that of CCFL.
therefore.
the service life of LED backlight is usually longer than that of CCFL.
.
the service life of LED backlight is usually longer than that of CCFL     4. Wide color gamut: in fact, it is the quality of the picture.
the color gamut is wideAccording to the different colors of light,
LED can be divided into white LED backlight and rgb-led backlight.
the main advantage of white LED technology is its low power consumption.
the advantage of rgb-led backlight is its excellent color expression.
rgb-led backlight can emit high-purity red, green, green light Blue LED device.
to achieve the traditional CCFL light source can not reach a wide gamut range.
the current mainstream rgb-led backlight has been able to achieve 105% of the NTSC gamut range.
LED device with more powerful performance can achieve more than 120% of the NTSC gamut range.
.
LCD is better.
less damage to the eyes.
