"LED LCD TV" is the most popular television market, and the vocabulary used liquid crystal TV CCFL back light, LED LCD TV more energy saving and environment protection, service life is longer. LED into the lateral shoot type LCD TVS and point-blank type two kinds, one side shoot type LED volume and light, direct type can be LED to get better color uniformity. Due to the lateral shoot type LCD TVS have LED back light ultralight ultra-thin appearance, so more and more consumers welcome!

Because the traditional liquid crystal TV coverage of color only standard range of 65-75 percent, the full range of colors, vivid less perfect show grassland, sea, maple leaf forest and other natural scene. Therefore, the traditional liquid crystal TV in color reduction has certain flaws. But now the fierce market competition, and constantly improve the taste of users, manufacturers unremitting look for alternative products to improve traditional liquid crystal TV gamut narrower defects. Finally, LED by backlight technology to liquid crystal TV. But for the average consumer, the concept of LED television is not very clear, here mainly introduce leds. Television,

Strong color performance

Traditional CCDL backlighting LCD TV in colour performance has been for people have noticed, but in place of this question after the advent of television LED to solve fundamentally. And condensing backlight constant lighting, LED backlighting is to point to adjust the lighting area and even the brightness, contrast and color in has greatly improved.

Currently the strongest LED TV can achieve NTSE 105% and color gamut, in aspects of color CRT, plasma perfectly match, foreign brand products have certain tests can be achieved by 150% of color. But not all LED television had 100% above NTSC color gamut, because LED into RGB - LED and white LED two kinds, RGB - LED by definition is red, green, and blue components of color gamut, LED the ascension has huge role, and the white leds is only used the spectrum of diode, just in LED light evenness and comparative advantage, have certain aspects of color.

Long service life

In addition to color gamut, TV and other features LED, long service life. The condensing CCFL LCD TV backlight manufacturer claims can reach 6 million hours of life, in fact, most DengZu backlighting reach all the life, because a DengZu backlit by the tube, as long as a root damage, can watch TV. Another CCFL tubes, high attenuation degrees about 7% a year, so, even if no damage down the brightness of the tube, also can be in 2-3 years significant attenuation.

CCFL backlighting average life expectancy in 2-3 million hours, and LED the life expectancy can reach 5-6 million hours, high quality LED back light life can even reach 100,000 hours, and the LCD panel, saves the life of change back light of trouble. This is one of the main advantages of leds.

Energy conservation and environmental protection

The traditional liquid crystal TV is back light kinds of restrictions on manufacturing process, must want to add some toxic substances, such as mercury, although use normally not volatilize, but if against, aging, appear to human health and environment has a lot of damage. Mercury is CCFL fluorescent lighting lamp and other types of ingredients, LED lamp, don't use mercury, environment and save resources on the negative influence of natural small lot.

Another aspect in power consumption has LED the obvious advantage of TV, because it can achieve alone in the dark, so controlled illumination scene under the brightness leds will reduce or even temporarily shut down, in the ChangLiang than CCFL tubes, in the state of energy saving effect significantly, such as a 55 inches in 200 TV, power leds watts around and 52 "LCD TV, CCFL power over 300 watts, long-term use of words in energy conservation in effective.

Appearance thin fashion

Traditional CCFL LCD TV because white is transmitted to join, so a neutral-density filter to achieve the goal, the filters imaging and LED is three color RGB - direct illuminate, without filter, so in the thickness of the TV can be further reduced, can easily reach traditional flat TV thickness half.

faults

Of course, everything is not perfect, LED LCD TV has deficiencies. It lies in the administrative and dynamic performance. In the darkness of the scene, performance, LED TV scene when the details of the picture, administrative depth is not obvious. This is the liquid crystal TV, dark scene of shadow detail.

In another important indexes, dynamic picture clarity. Regardless of how to change back light, LED ultimately LCD TV of a liquid crystal TV, so common in some flaws, LED the liquid crystal TV. But 200Hz series compensation technology constantly upgrade, can effectively reduce the delay picture. In addition, LED by television because of the diode luminescence technology, so is in the heat.

Now only be allowed LED LED TV, or it is LCD TV, LCD, but LED a branch of liquid crystal TV on the huge advantage on the back light in color, and energy saving, environmental protection, appearance etc are leading CCFL LCD TV. But along with the technical capacity and reduce the threshold of ascension, the price has solved the problems such as expensive also. Perhaps in the television market shortly, LED to the dominant.
