Hello everyone, Lin Fei to answer the above questions, what is the brand of led TV, what is the meaning of led TV many people still do not know, now let's take a look at it!

1. TV is indispensable in every family. As TV sets continue to enter people's family life, many parents will think of buying better televisions when they are ready to buy them. However, most people do not understand the difference between LED TV and LCD TV. This paper introduces the difference between led TV and LCD TV.

2. The difference between led TV and LCD TV

3. At present, all the home LED TVs on the market are actually a kind of LCD TVs, but the backlight is different. LCD is the general name of LCD TV. LED is a backlight technology of LCD TV, which belongs to LCD, not its peers. The equivalent of leading is CCFL. For publicity purposes, CCFL is called LCD.

4. LCD and LED refer to the two development stages of LCD TV backlight technology, and they are also the two main LCD TV backlight technologies in the market at present. But no matter which kind of backlight technology, the principle of liquid crystal itself is the same. The liquid crystal itself does not emit light, so it needs backlight. This lighting technology is divided into LCD and LED. Compared with LCD,LED technology is more advanced, the overall visual effect is better, more energy-saving, of course, the price will be higher.

5. Comparatively speaking, LED as a backlight can make the display screen thinner and lighter, and the color rendering effect will be better. Another important problem is that LCD TVs use cold cathode fluorescent lamps, which are also considered harmful to the environment because they contain mercury. But LED LCD TVs use light-emitting diodes and there is no mercury problem. However, for end consumers, even if the traditional LCD TV containing mercury is used, it will not directly harm the body and the environment in the actual use process. This kind of environmental protection problem is actually aimed at the production link and the future recovery link. This is also a misunderstanding that many people do not easily understand.

6. What's the difference between LED and LCD?

7. LED refers to light emitting diode (Light Emitting Diode), and what we call LED refers to the liquid crystal display with LED as the light source.

8. LCD refers to the liquid crystal display, which uses CCFL (cold cathode fluorescent lamp) as the light source. They use different backlights.

9. Compared with the LCD which uses CCFL (cold cathode fluorescent lamp) as the light source, the LCD panel with LED as backlight has the greatest advantages in the following three aspects:

10. First of all, the thickness of LCD with LED backlight will be further reduced.

11. The panel thickness of the LED notebook screen is about the thickness of the ordinary CCFL screen.

12. Second, it has a longer life, lower power consumption and more environmental protection.

13. The service life of LED is up to 100000 hours. Even if it is used continuously for 10 hours a day, it can be used continuously for 27 years. After using the LED backlight system, the energy consumption can be greatly reduced, saving 48% more than the CCFL LCD. And LED does not use mercury that is harmful to the environment, so it is quite environmentally friendly, while CCFL contains mercury.

14. Third, the color expression of the LED backlit screen is much better than that of CCFL.

15. Due to problems such as color purity, the original CCFL backlight does not perform well in color levels, resulting in LCD not as good as CRT in grayscale and color transition. According to the test, the CCFL backlight can only achieve 78% of the NTSC color area, while the LED backlight can easily achieve 100% of the NTSC color area. LED backlight also has significant advantages in color performance and color level transition.

16. After reading the introduction above, it turns out that LED TV is actually a kind of LCD TV. After seeing the rising posture, the two should not be confused in the future.

At the end of this article, I hope it will be helpful to you.
