Hello everyone, Lin Fei to answer the above questions, the difference between LCD TV and led TV, the difference between LCD TV and led TV, many people do not know, now let's take a look!

1. Now almost every family has a TV they like very much, and people watch TV at home when they have nothing to do. But when people watch TV, they only care about the plot, but they don't care about their own TV. Among them, the televisions at home are mainly led TVs and LCD TVs. Then I will briefly introduce the difference between LED TV and LCD TV in terms of nature and characteristics.

2. The essential difference between led TV and LCD TV.

3. TV refers to the TV set with LED (light emitting diode) as the display device, which is generally used for low-precision display or outdoor large screen. At present, Chinese mainland home appliance industry commonly known as LED TV, the strict name is "LED backlit LCD TV", refers to the LED backlit LCD TV, or a kind of LCD. It uses LED light source to replace the traditional fluorescent tube, the picture quality is better, the theoretical life is longer, the manufacturing process is more environmentally friendly and the LCD panel is thinner.

4. The full name of LCD is LCD: it includes many types of LCD, such as TFT, UFB, TFD, STN and so on. The structure of LCD is that the liquid crystal is placed between two parallel pieces of glass, and there are many small wires between the two pieces of glass. The direction of the rod-shaped crystal molecule is controlled by whether it is electrified or not, and the light is refracted to produce a picture.

5. The characteristics of led TV.

6, Lcd display a large amount of information (because pixels can be done very small), long life (this kind of device almost no degradation problem, so the life is very long, but the LCD backlight life is limited, but the backlight part can be replaced), the most important thing is no electromagnetic radiation (security for the human body, conducive to information secrecy).

7. Led environmental protection and energy saving. CCFL cold cathode fluorescent lamp, which is backlit by traditional LCD TV, contains mercury which is harmful to human body. Although manufacturers are working hard to reduce the content of mercury in cathode fluorescent lamps, mercury-free fluorescent lamps will bring some new technical problems. LED backlight never contains mercury, in line with the fashion of environmental protection. LED backlight is also very power-efficient. The internal driving voltage of LED is much lower than that of CCFL, and its power consumption and security are better than that of CCFL. LED has a wide color gamut and different luminous colors, which can be divided into white LED backlight and RGB-LED backlight. The advantage of white light LED technology is mainly low power consumption, while the advantage of RGB-LED backlight is excellent color performance.

With the improvement of people's quality of life, people's household appliances and travel have been greatly improved. Nowadays, people will change a very useful TV for their home. When people buy a TV, they only know led TV and LCD TV, but they hardly know the difference between them. In the end, they foolishly bought the TV set home. Let me briefly introduce the difference between led and LCD TV. I hope I can give you some help when choosing a TV.

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