Advantages of LED display
Advantages of LED display·Advantage 1: wide color gamutCCFL (cold cathode lamp) backlight is used to excite the phosphor to emit light. It has many impurities in the luminescence spectrum and low color purity, which leads to its small color gamut, which is only about 70% of NTSC.
however, the luminescence spectrum of LED is narrow.
the color purity is good. The backlight mixed with three primary colors LED has great color gamut and excellent color reduction, Compared with the traditional CCFL backlight, it can reach 105% of NTSC and expand the gamut by about 50%.

What is the difference between LED display and LCD display? Which is better?

the results show that the color gamut of CCFL backlight is much larger than that of NTSC·Advantage 2: longer lifeGenerally speaking,
the service life of LED backlight is longer than that of CCFL.
the rated service life (half bright) of different CCFLs is between 8.
000-100000 hours, while the service life of LED backlight is about twice as long as that of CCFL.
moreover, the service life of CCFL backlight with improved design will be lower in order to enhance the performance.
in addition, the service life of CCFL backlight with improved design will be lowerIn addition.
due to the circuit design, the size of LCD with LED backlight is expected to be smaller, and the cost of circuit design will be greatly reduced.
in addition, the LCD with LED backlight is expected to be smaller·Advantage 3: environmental protection and energy savingIn the LCD with cclf cold cathode fluorescent lamp as backlight,
one of the main elements that can not be lacked is mercury, which is also known as mercury, and this element is undoubtedly harmful to human body.
in the LCD with cclf cold cathode fluorescent lamp as backlight, mercury is the main element that can not be lackedAlthough the manufacturers have tried their best to reduce the mercury content in fluorescent tubes.
however, the completely mercury free fluorescent tubes will bring some new technical problems, which can not be realized for the time beingIts advantage is that it does not contain mercury at all, which is in line with the fashion of green and environmental protection.
it has the advantages of low mercury contentThe power consumption of LED backlight is lower than that of CCFL cold cathode backlight.
the internal driving voltage of LED is much lower than that of CCFL.
the power consumption and safety of LED backlight are better than that of CCFL (the AC voltage requirement of CCFL is relatively high, reaching 1500-1600 VAC at start-up, and then stabilizing to 700 or 800 VAC), while led only needs to work at 12-24 VDC or lower voltage.
the power consumption and safety of LED backlight are better than that of CCFL·Advantage 4: ultra thin appearanceIf LCD TV is to be ultra-thin, there are two main determinants: the thickness of the backlight module and the power supply substrate. However, the whole area of the backlight module is similar to that of the LCD panel, while the power supply substrate only accounts for part of the area of the LCD TV. In other words, the thickness of the thinnest part of the LCD TV has a lot to do with the backlight module.
the thickness of the thinnest part of the LCD TV has a lot to do with the backlight moduleThe side light LED in LED backlight is used in LCD backlight module for TV.
its thickness is thinner than that of CCFL straight down type, side light type and led straight down type. For Samsung's 40 inch TV LCD panel with a thickness of 10 mm, the thickness of the backlight module is only about 5 mm.
