CCFL backlight issues such as
color purity, poor performance in gradation, resulting in grayscale and color
LCD transition than CRT. According to the test, using the NTSC color CCFL
backlight can only achieve about 70% of the region, even through the use of
improved CCFL light source, can only reach about 90% of the geometric NTSC
color gamut, which is now wide color gamut display . The LED backlight NTSC
color area is about 80%, another RGB LED backlight is a high-end design, NTSC color
gamut area of up to 100 percent, of course, the high
cost of this design, temporarily appear in high-end LCD TVs. Overall, the color
performance and gradation transition, LED backlight does have advantages over
LCD.

"BLOONING" bursting with energy saving
flag
2, LED long life, low power consumption, strong
power, more environmentally friendly
I believe there are some old users will feel that
his monitors started yellowing, after disassembled, there are not difficult to
find the lamp has burned out. This is because the average life of CCFL
backlight generally in about 25,000 hours, top CCFL backlight luminescence
lifetime but also 60,000 hours, late in life, LCD brightness will be
significantly decreased, had to replace the CCFL LCD backlight module. But at
this stage the actual white LED backlight life of 50,000 to 100,000 hours, and
the life of the LCD display are basically the same, but also the potential to
increase again. Even 12 hours of continuous use every day, you can spend 10 consecutive
years.

Power consumption, already mentioned above, the AC
voltage to the CCFL requirements are relatively high, start up 1500 ~ 1600 Vac,
then stabilized to 700 or 800Vac. They also require
power inverter
to a DC
power supply, which increases the cost of the application, footprint and
weight. In contrast, typical LED backlight subsystem 12 ~ 24Vdc or lower
voltage. Actual power consumption, from the previous test, we can see that,
CCFL designed 19-inch widescreen full power about 35W, while the LED backlight
is 14W, super power.
I believe that many users purchase IT products,
there RoHS see this sign, in fact, the instruction is representative of the
electronic products do not lead, cadmium, mercury, hexavalent chromium,
polybrominated biphenyls and polybrominated diphenyl ethers and other
substances, and Mercury is the CCFL and other types of fluorescent lighting,
the main ingredient, LED backlight not contain mercury, so now the United
States and Europe have strongly recommended LED-backlit LCD.
3, LED LCD more light than the LCD
Maya; X2010
From the figure can be seen a structure, since the
light emitting diodes and fluorescent tubes have different physical thickness,
resulting in both the degree of the finished plate on a qualitative difference.
Theoretically, LED backlit LCD CCFL backlit display thickness is only half the
battle. Of course, LED-backlit LCD surface portion of the design is limited, if
you display manufacturers to consider with a more robust built-in power solutions
will increase the overall thickness of the CCFL backlit display will look like
thick or less.

LED disadvantages:
1, the price to be slightly higher than LCD;
initially launched in the LED, its construction cost is relatively higher than
LCD, but with the development of technology, LED's cost reduction is
inevitable, the price gap between the two will slowly narrow;
2, LCD technology reaching maturity; prevailed for
the last ten years of research and development of LCD products, its technology
is of course to come than the LED new maturity. However, as is the development
of LED LCD, replace the LCD is inevitable!

Maya bloom X2010 is a 20-inch LCD, while in the
performance, in addition to the above said Maya bloom X2010 LED technology
brings three advantages, its 10 million: a high-contrast, no doubt so that the
clarity of the display has been peaked, the best resolution 1600 * 900, 5MS
response time, VGA port, and 250 lumens of brightness, can meet most of the
needs of consumers. Meanwhile, there are 16:9 and 4:3 bloom X2010 conversion
function to facilitate some of the needs of users, can be described as quite
humane.

Currently, this new look extremely gorgeous Maya,
priced at 1,099 yuan, a 20-inch LED LCD, this price is quite affordable,
because the average 20-inch LCD is the price. Like Maya consumers of this
SUNGOLDPOWER
product, you can sell.
