Of course, LED is good, but the price is more expensive.
Of course, LED is better, but the price is more expensive.


the difference between liquid crystal and LED is as follows:
in the current market.
liquid crystal displays are mainly divided into two categories, one is the traditional CCFL (cold cathode fluorescent tube) liquid crystal display, The other is LCD with LED backlight.
many consumers directly call the first type of display LCD.
that is liquid crystal.
the second type of display is called led.
in short.
LCD and LED are two different display technologies. LCD is a display composed of liquid crystal, However, LED is a display screen composed of light-emitting diodes.
compared with CCFL display, LED display has more advantages in brightness, power consumption, body volume, life and so on, while CCFL backlight has more advantages in color performance, power consumption and so on Led: advantages:
1. The screen can be thinner. We should pay attention to some liquid crystal displays.
we can see that there are several CCFL lamps arranged in filaments. In order to make the screen shine evenly, we need to add some other devices, so we can't be very thin; The backlight is different. The LED backlight itself is a planar light-emitting material, and there is no need to add other devices.
2. It will not turn yellow and dim. CCFL fluorescent lamps are the same as fluorescent lamps.
after a long time, they will age, so the traditional notebook screen will turn yellow and dim in two or three years, and the life of the LED backlight screen will be much longer, At least two or three times.
3. More power-saving LED is a semiconductor.
working under low voltage, it has simple structure and low power consumption.
4. More environmental protection. Mercury in CCFL light has great pollution to the environment.
2Harmless recycling has great difficulties.
disadvantages: relatively high price. At present, the price difference between CCFL backlight display and traditional CCFL backlight display in the same specification is between 100-300 yuan.
advantages of liquid crystal.
1. Long time to market.
technology is relatively mature.
2. More stable color.
professional display is still used.
3. Relatively low price.
1. Short service life after 2-3 years of use, the LCD screen will turn dark and yellow, which is caused by the short service life of CCFL.
2 The brightness output uniformity is poor.
when all white or all black pictures are displayed.
the brightness difference between the edge and the center of the screen is very obvious.
3. Large size.
4. High power consumption and high calorific value.
the biggest advantages of LED TV are low power consumption and good definition.
it is a popular product now.
