Although there are many "LED TVs" in today's home appliance stores, they can't really be called true LED TVs, but only LCD TVs with LED backlights, compared with ordinary CCFL light source LCD TVs. It's just the difference in backlight.
So what is the real LED TV?
LED TV can actually be seen as an upgraded version of the LED display we often see, by controlling tens of thousands of RGB three colors
The picture presented by the
LED Light. Each light source of an LED TV is self-illuminating, which is fundamentally different from the principle of imaging the main back light source of a liquid crystal television.
What are the advantages of true LED TV?
1, the size can be expanded infinitely. The traditional LCD TVs currently have a maximum size of 110 å‹. If they are large, they have great problems in terms of technology, cost, and yield. LED TVs do not have this limitation. They are assembled from basic LED units. Therefore, the size can be customized to meet the needs of the user. Previously, companies have shown 288 LED TVs.
2, can be customized creative TV. Since LED TVs are assembled from LED units, of course, in addition to the size can be customized, the shape can also be customized, such as today's very hot curved TV, the technology is much simpler for LED TV, it is easy to achieve.
3, large size price is very advantageous. The price of a 60-inch LCD TV is around seven or eight thousand yuan, and the price of a 70-inch LCD TV needs two or three thousand. If it is a little bigger, such as the 85/84-inch LCD TV displayed in the store, the price is mostly More than 100,000, and the larger size of the LCD TV, the price will need hundreds of thousands. The price increase of LCD TVs has grown geometrically with the increase of size, and the LED TV screen has become larger, only the LED unit has been increased, so the price is also proportionally increased, for example, the price of 2 square meters is doubled compared to the 1 square meter screen.
4. The cost of repairing dead spots is low. The most feared thing about LCD TVs is that the screen has a bad point. If there is a problem with the screen, the entire screen has to be changed. The LED TV has a problem of lamp damage, and the damaged lamp can be replaced separately, and the maintenance cost is much lower.
Since LED TV has so many advantages, why can't it develop rapidly? The author believes that the main thing is in appearance and clarity.
First of all, LCD TV has an important hardware indicator called pixel point, and LED TV is called point spacing. The point spacing is generally the distance between LED Lamp beads . The smaller the dot pitch, the smaller the graininess of the video, and the picture will be. clearer.
At present, the dot spacing of LED TVs is still millimeter-scale, such as 1.2 mm, 1.0 mm, which is not the same as the pixel pitch of the LCD TV micron level. Therefore, LED TVs are not suitable for small sizes, and are more suitable for viewing large sizes up to 4 meters.
Secondly, the LED TV is made up of LED units. There is very little refined design for the exterior part, and the ultra-thin design is not on a level relative to the LCD TV. Therefore, further technical research is needed.
In any case, the real LED TV has gradually emerged. With the further development of technology, it may soon be infiltrated into ordinary families, which will have an impact on the traditional TV industry. We will wait and see.
