OFweek smart home network news: Samsung TV in 2014 optimistic about the quantum dot technology, by investing in 300 quantum dot technology patent German Nanosys company and the acquisition of the United States Quantum dot company QD Vision complete the quantum dot technology layout, and in the TCL, Hisense and other color TV manufacturers Followed and led OLED technology to form two distinctive technical characteristics of the LG camp. In terms of OLEDs, LG has been sticking to it since 2012 and is also continuously promoting the iterative updating of technologies and processes. Since then, in the field of television, Quantum Dots and OLEDs have opened up a controversy over the future of display technology. For many years, the problems of quantum dots and OLEDs have been controversial in the industry. However, with the launch of Samsung QLED TV in 2017, the balance of the two major display technologies that have been relatively balanced has slowly changed. "QLED" Or will play a "terminator" role in the dispute between quantum dots and OLEDs.
Quantum dots interpretation "speed and passion" for the future display technology name
In the color TV industry, there was a saying that had been widely circulated earlier: "The amateurs look at the liquid crystals, the insiders watch the plasma," and they talk about the battle between the two major display technologies between the plasma and the liquid crystal. Plasma has high hopes in the industry at the beginning of its launch. It has many advantages: large viewing angle, good uniformity of brightness, large dark field dynamic range, rich image hierarchy, low image smearing time, high dynamic resolution, and color reproduction capability. Well, the display color is natural. These congenital advantages have surprised millions of enthusiasts. At the same time, they let many TV manufacturers determine that plasma will always occupy a place in the fierce battle of flat-panel TVs. However, the results turned out to be counterproductive. LCD TVs became a mainstream display technology. The initially favored plasma fell apart. This shows that the trend of disputes is not only a dispute over the quality of technology, but also a multifaceted battle between products, markets, and marketing.
Looking back at the future display debate between Quantum Dots and OLEDs, OLED seems to have a tendency to follow the trail of plasma. At the "2017 International Quantum Dot Display Industry Forum" conference held recently, "QDs are the next generation of display technology" has been unanimously approved by the leaders of the on-site association, experts and professors, color TV manufacturers, and channel distributors. At the forum, Gome, Suning, Jingdong, Tmall, Zhongbai, Tangbai and other channels signed on-site with quantum dot TV manufacturers to help promote the popularization of QD TV consumption. It is reported that Samsung, TCL, Hisense, and channel distributors will reach a contracted amount of 10 billion yuan this year. Experts at the scene said that Quantum TV may usher in a big explosion in 2017 with multiple upstream and downstream linkages. In order to meet the popularity of quantum dot technology, Samsung, the industry leader, introduced a huge QLED TV lineup this year, which includes 4 series and 8 models spanning 55 to 88 inches. "With passion", through the three-dimensional force of product, market and marketing, this technology is known as the quantum dot.
Technical level, QLED has obvious advantages
QLED vs. OLEDs have continued for several years. There are still many unresolved problems in OLED TVs that appeared several years ago. Before that, Peng Xiaogang, a professor of chemistry at Zhejiang University, publicly stated that OLEDs are inherently unstable, and the yield of OLED TVs cannot meet commercialization requirements and costs are high.
In contrast, the quantum dot technology, because the quantum dot uses a solution semiconductor nanocrystal, only needs to change its size, it can adjust the desired color, and the color purity, crystal stability is very high, no need to worry about the service life. Many people in the industry have stated that quantum dots may be the best luminous material that humans have ever discovered.
At present, Samsung is undoubtedly the leader in quantum dot technology. Since the successful acquisition of US QD Vision last year, Samsung has further established its dominance in the field of quantum dots. From the first-generation quantum dots, to the second generation of cadmium-free quantum dots, to this year's latest QLED, Samsung has been focusing on the development and innovation of quantum dot technology. This year, Samsung introduced QLED TV, which uses nanocrystalline semiconductor quantum dots as its material. This extremely tiny particle can produce a unique chemical reaction with light, making the color the most perfect representation. This is due to the fact that nanocrystalline semiconductors have greater luminous efficiency and can express all colors correctly in brightly lit and colorful images, and have almost unlimited image lifetime.
The most prominent feature of the QLED TV series is that it not only accurately displays the color space of the DCI-P3, but also produces a color rendering volume of up to 100%, with three display characteristics of “bright, long, and wideâ€, high peak brightness and color gamut. High value, pure color and stable and lasting, all colors can be restored at any brightness level, and the quality of the picture is amazing, bringing a visual experience closer to the real world.
In addition to the leading edge of display technology, Samsung QLED TV has more obvious advantages in human-computer interaction and content construction. The tidy and clean Tizen system makes the user's interaction easier, and the newly designed Samsung universal remote controller can help users find the content and services they need more effectively. In addition, this year Samsung will extend the Smart Hub operation interface to the main screen of the mobile phone APP for comprehensive content preview through the newly upgraded Smart View APP. Users can select their favorite TV live shows and video on demand services through the Smart View APP on their mobile phones. In terms of content, Samsung TV is authorized by Mango TV, GITV, iQIYI, CIBN, NewTV, Tencent Video, PPTV, Youku, and up to eight video platforms. You can watch live TV drama variety resource programs directly in HD. The new movie will also be updated to the user at the first time. It can be said that you can see the world without leaving home.
At the market level, QLED represents future trends
In terms of market, the actual performance of quantum dot TV is much better than the early introduction of OLED TV in the past two years. According to the data from China Yikang, the retail sales of quantum dot TVs in 2016 were more than seven times higher than those of OLED TVs. In the first week of 2017, QD TV's retail penetration reached 4.77% in the color TV market, while OLED TVs only achieved a 1.22% retail penetration rate over the same period. The famous market research agency NPD Display Search predicts that the annual growth rate of quantum dot TVs in the Chinese market will reach 100%, which is expected to grow from 600,000 units in 2016 to 1.2 million units in 2017, and will also increase from 3 million worldwide. Taiwan increased to 6 million units.
According to Lu Jiebo, a well-known household electrical appliance expert and deputy secretary-general of the China Electronic Chamber of Commerce, China's color TV industry has gradually returned to the picture quality route. Quantum dot technology has become the mainstream display technology for color TV products and there is no suspense. The continuous improvement of this technology will continue to strengthen. The competitiveness of LCD technology camps. Under the high-end trend of color TVs, quantum dot technology will undoubtedly lead the new high-end television industry.
With the launch of QLED TV with Samsung Quantum Dot technology, it will inevitably create a new buying effect in the market. In particular, with the rise of the middle class and the advent of the consumer upgrade era, high-level consumers will have higher and higher requirements for the quality and experience of color TVs. QLEDs, which represent the trend of technological innovation, will be polished in Samsung's ultimate design. It will inevitably bring consumers an ultimate visual experience closer to the real world.
