And technically, OLED screens will become dark after being used for a long time, and there will often be serious afterimages. This has always been a major concern for everyone. And even though the colors are too bright, they look good, but they also hurt the eyesight. So even though OLED screens have been launched for several years, mainstream manufacturers in the industry have also been conducting research and breakthroughs in this area in recent years. Unfortunately, the results are not so great. Therefore, the current mainstream LCD screens are still IPS. Of course, IPS is also a very good screen, but at the moment it has seen many users complain that the IPS screen has more serious light leakage and is not very satisfactory in terms of color contrast. In this case, the real breakthrough in the industry will probably fall on the quantum dot screen.
Quantum dot screen ushered in the growth of the first year Quantum dot is a new generation of TV screen technology, some time ago to participate in the new conference of TCl, there are two X series flagship Quantum TV release, 6.9 mm ultra-thin body, color The coverage rate of the domain is as high as 157% (Apple's most famous Retina screen can only reach 100%), and it has a purity of 1.07 billion colors (generally LCD display color is only tens of millions), and the life span is more than 60,000 hours. Equipped with a full-scale HDR, it achieves the highest level of DolbyVR HDR certification, basically reaching the limit of the screen. Its superiority is that the current IPS screen and even the OLED screen cannot be compared. In the screen technology, a crossover is realized. The leap of the era has also proved the gradual maturation of quantum dot technology. 
China's own technological advantage speaks of LCD screens. Everyone knows that most of the production lines and technologies are still in the hands of foreigners. It is like the screens of domestic mobile phones that come and go. When Samsung first encountered the explosion door, it began to raise the price of the screen to hedge losses. This also led to the domestic panel began to sharply increase the price, causing price fluctuations in the mobile phone and television industry. However, on the quantum dot material, China’s own research power is much stronger, such as BOE, China Star Optoelectronics, Longteng Optoelectronics, etc. The TCL just mentioned is the product of Huaxing Optoelectronics, which was invested by itself, so the display of quantum dot technology The screen upgrade is actually conducive to breaking the international monopoly and establishing China's own manufacturing advantages. 
Although the upgrading of software can enhance the user experience in content, television is still a screen-reading product. The better screen display technology of quantum dots will become the outlet for upgrading TV hardware. It is believed that in this round of tides, the TV industry will have a new pattern, and whoever has mastered newer technologies and better products will naturally achieve greater development.
Smart TV/box information can focus on smart TV information network sofa butler (http://), China's influential TV box and smart TV website, providing information, communication, TV boxes, smart TVs, smart TV software, etc. Answering questions.
In recent years, the television industry has undergone great changes, especially the appearance of Internet TV, which has led to great changes in the pattern of the entire television industry. This can actually be said to be an upgrade of television in software systems, and television has begun to face a subversive progress in hardware, that is, the increasingly mature quantum dot screen technology. OLED can't take up the upgrade of the TV screen. In recent years, the TV screen has been in the air of upgrading. The hope of undertaking this screen upgrade has always been on OLED TVs. Compared to traditional LED and IPS TVs, OLED screens are indeed very obvious. For example, they can be super-thin, bright and colorful, no smearing, simple structure, and almost no viewing angle. High efficiency and bendable flexible display state. However, the disadvantages of OLED screens are also obvious. For example, OLED screens have a shorter life expectancy, and the display time is only 5,000 hours, which is almost one-third of that of LCD TVs. Basically, there is no way to use it as a commercial product, but in the case of home use, the price is actually relatively high. Can achieve such a display effect, or because the quantum dot technology is actually a breakthrough of new materials and new technologies, the display principle is that after the solution nanocrystals are stimulated by electricity or light, they will issue various differences according to the diameter of the quantum dots. Very pure high quality monochromatic light of color. Because the quantum area is of course extremely small, this allows the screen of the quantum dot to display more colors and cover a higher color gamut. And its lower price compared to OLED has also been recognized by consumers. So even though QDTV is a new technology TV, last year's sales volume has been more than seven times that of the OLED LCD TVs that have been on the market for many years. At the same time, under the impetus of a number of quantum dot giants around the world, QD TVs in 2017 are likely to bloom in full. Although they are still only present in some high-end products, with the continuous advancement and popularization of technology, quantum dot technology has been applied to The middle and low-end products are also a matter of course. At the 2017 International Quantum Dot Display Industry Development Forum, the industry signed 10 billion large bills, symbolizing the beginning of the quantum dot TV era. What is worth mentioning here is TCL's vision of quantum dots. Since the establishment of Huaxing Optoelectronics in 2010, we have been making great efforts to build high-generation panel lines with independent intellectual property rights, and invested in Zhejiang University’s nanocrystalline technology, dedicated to quantum dot new In 2014, the company launched the first Quantum-dot TV in research, manufacturing, application technology and product development. It can be said that through the huge investment and research in the early stage, TCL finally stood on the same starting line with the international giants on the quantum dot track. It is very likely that TCL will make more important progress in this new wave of upgrades. Achievements. In 2016, TCL shipments exceeded 20 million units, which fully demonstrated the results of accumulating results.
