As soon as many people hear about LED TV, they think it is a newly developed brand-new TV set. In fact, this is wrong. LED TV is also a kind of LCD TV. Its real name is: LED backlight LCD TV. It just changes the CCFL backlight technology of ordinary LCD TVs into LED backlight technology. Therefore, LED TVs only carry out certain upgrades on ordinary LCD TVs. In essence, it still belongs to a kind of LCD TV.
LED TV is generally much thinner than ordinary LCD TV, thin up to 29.9mm, or even thinner, so whether it is placed on the TV cabinet or hanging on the wall, it is very convenient.
People who have compared carefully will find that the colors of LED TVs are more real than ordinary LCD TVs, especially for high-definition movies, because the color gamut of LED TVs can reach 105, while ordinary LCD TVs are far less than ordinary LCD TVs.
LED TV has a very great advantage in this respect. According to statistics, the general LED TV can support about 100000 hours, that is to say, if you watch 8 hours a day, you can use it for 34 years, while ordinary LCD TVs are easy to age and use much less time.
According to data analysis, LED TVs of the same size save about 50% of computers compared with ordinary LCD TVs, so they save electricity very much.
Although LED TV has so many advantages over ordinary TV, there is still one disadvantage that has not been improved: visual angle; like LCD TV, it must be directly opposite the screen in order to achieve better visual effect, if it is too high, too low or too partial, it will cause obvious distortion.
A: Direct type: refers to the LED lamp evenly distributed in the back of the LCD screen, the light through the panel; so the direct type is easier to achieve a clear layer of light and shade effect, because it can adjust part of the tail light on and off according to the demand.
B: Side projection type: refers to the LED lights distributed on the edge of the screen, through the light guide plate to spread the light evenly to the screen; it is for this reason that the side projection LED TV can be made very thin, but because the edge and central lights are poor, it will cause uneven screen brightness.
LED TV is more cost-effective than LCD TV, although it has a high one-time cost, but it has the advantages of low energy consumption, high user experience and long service life, so it is more worthwhile to choose LED TV.
These are the differences between led TV and LCD TV and the special points of LED TV. It is obvious that LED TV has great advantages, and it will gradually replace ordinary LCD TV and become the mainstream of household consumption.
