At present, LCD panels are among the top four in the world-AUO, Chi Mei Electric, LGD and Samsung, but all of them are supported by Japanese companies (lines, equipment and raw materials, quite comprehensive help, and Japanese electromechanical companies you see in the market are basically involved, such as Sumitomo, Mitsubishi, SMC, Imperial Ink, Nitto, Toray, Nikon, Toshiba and Hitachi. ).
Plasma display panels can be said to be Panasonic's monopoly, occupying at least 70% of the market share. Changhong's plasma has a complicated relationship with Panasonic (since the CRT era, with the support of Panasonic, Changhong has become the world's number one CRT and exported to the whole world, but what was pieced together by Panasonic's friends was South Korea's Opel, which was later acquired by Changhong as a plasma screen. //Very complicated//.
LED backlight (only LED backlight, the front is still LCD panel, but the back backlight is EEFL tube, and about 12 tube is used for 32 inches). The lamp tube has a limited life and is easy to break, and it will flash and yellow after a long time. Moreover, in 2007, the diameter of the lamp tube was generally 4.2MM, and now it is generally 3.4MM (the price reduction is raging, but the suppliers of the lamp tube are all big manufacturers: Hitachi, Sanken Third Research Institute, Japan and Asia, etc.).
Anyway, Korean and Taiwan Province companies are the first in this industry, and most of the accessories behind them are Japanese companies, from tape to glasses and polarizers.
So don't worry.
It doesn't matter which one you choose.
As for the key components of LED backlight, LGP light guide plate (raw materials are usually Sumitomo Chemical and Mitsubishi Chemical) and LED particles (currently Seoul Semiconductor of South Korea, GE+CREE of the United States and Riya of Japan are all super suppliers).
So don't worry.
There are basically no Chinese mainland enterprises, so there won't be too many quality problems.
As for 3D, the switchable 3D solution without glasses is provided by American 3M Company, which is a known supplier of all LCD panels, so there is no need to worry.
Enterprises in Chinese mainland do two jobs in the middle.
1, final assembly (foreign labor is expensive and China workers are cheap)
2, misleading China consumers, as if China can do anything.
According to Hisense's TV situation:
46 inches, no accident should use Samsung's screen, Hisense and Samsung's cooperation is more comprehensive. Now Hisense has opened its own backlight module factory. It turned out that it bought a whole set of display panels from Samsung, and added signal receiving equipment and casing. Now it purchases the front glass panel and assembles the backlight module at the back, but many important raw materials are still imported. For example, LED particles, or lamp tubes, as well as various optical reflection films, brightness enhancement films and so on.
At present, the backlight of LED panel is mainly side incident light source. The LED arrays are on both sides of the LGP light guide plate, and the irregular lattice particles printed on the lower surface of the LGP light guide plate are used to disperse and gather the side light, otherwise it will be too bright around and too dark in the middle. The bottleneck of this model lies in the output of LGP light guide plate. Because all mobile phone screens, laptop screens and desktop LCD monitors use this material, but now it is used in LCD TVs. Although the quantity is not very large, the size of a single product is large, so considering the weight, the original supply is still quite tight. However, there are only a few suppliers of this kind of raw materials-Sumitomo Chemical, Mitsubishi Chemical, Asahi Kasei Chemical, LG Chemical and Chimei Chemical (Samsung series should also have its own supporting factories such as Samsung Textile, but the specific situation is not very clear), so there have been cases where the Samsung purchasing boss took all suppliers to various original board manufacturers to sign agreements for stable supply. Sharp has made a breakthrough in this regard. At present, the direct LED backlight has been developed, which can be realized by lens principle and LGP can be cancelled. At present, there is only one high-end opportunity, that is, patent.
As for a friend who asked whether China display can win an award in international exhibitors, he can only say that the flat panel display industry in China still has a long way to go. You can pay attention to Corning Company in the United States, which is the largest supplier of glass substrates at present, accounting for 60% (almost closed down that year, and one product saved a company! ), they have Samsung Corning in South Korea and branches in Japan and Taiwan Province Province. Why not in Chinese mainland? Because there is no real LCD production line here!
As for the poor panel in Taiwan Province Province, this is a false topic. In fact, there is basically no difference between good and bad LCD panels. Just because everyone embarked on a road in those years, there were patents everywhere on the road, so we went all the way down. If it is really good or bad, the products of the same company also have high or low points. Buying an LCD panel must be good and expensive, and it must be good.
