Quantum dot core structure
Quantum dot display technology has been fully upgraded in various dimensions such as color gamut coverage, color control accuracy, and red, green and blue color purity. It is regarded as the commanding point of global display technology and is also regarded as the global display technology revolution.
Quantum-dot TV sounds very unpredictable, in fact, QLED TV is another name, QLED is "Quantum Dot Light-Emitting Diode" shorthand, the Chinese translation is "quantum dot light-emitting diode."
Quantum-dot TV is a kind of TV that uses the quantum dot technology backlight and is a kind of LCD TV. It differs from traditional LCD TVs in that it uses different backlights, resulting in a lot of differences in performance. Compared with conventional LCD-backlit LCD TVs, it has advantages in picture quality, energy saving and environmental protection, and it has become a new LCD TV in the industry. The direction of development
According to the authoritative inspection data released by Liu Zhigang, deputy general manager of the National Radio and Television Product Quality Supervision and Inspection Center, the color gamut of ordinary LED TVs is only 72% under the NTSC standard, and only 82% of the first-generation high-color televisions are the second generation. High color television is about 96%, while quantum dot TV color gamut coverage is as high as 110%.
Let's take a look at the advantages of QD TV
1. Full color gamut display advantage.
2. High color purity.
3.95% is close to natural light, strong in color reproduction, and excellent in color rendering.
4. Inorganic materials. Strong stability, long life, not easy to aging.
5. Precise color control.
6. High efficiency and strong energy saving.
7. Quantum dot TV cost is lower.
The main advantage of quantum dot technology is that it can achieve high image quality close to OLED at only 1/3 of the cost, while also solving the problem of “black not black†that LCD has never been able to overcome, and a broader color gamut display. More precise color control, longer life, and lower energy consumption. Only need to change the size of the quantum dot, you can call up the desired color, and the color purity is very high, brings the full color gamut display capability, narrowband continuous spectrum, higher color purity, 95% close to natural light, powerful color reproduction The color accuracy of the high crystal stability is also very high, which is difficult for other materials.
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 rate reached 4.77% in the color TV market, while OLED TVs only achieved a 1.22% retail penetration rate over the same period. Relatively speaking, OLED TVs have been on the market four years ago. The advantage of promotion and publicity is even greater, but they are still ranked by QD TV. It shows that the same is emerging display technology. In terms of the quality of the consumers concerned, OLED organic. The inherent short lifespan of materials and the low yield rate are doomed to difficult quantum dot technology. TV companies have been destined to be widely accepted by the market when choosing next-generation display technologies.
On May 12th this year, Suning, Hisense, Samsung, and TCL held the "Quality Point Shopping Festival Launching Ceremony" at the Suning Life Square Store in Xi'an to provide consumers with more quality quantum dot products. Hisense, Samsung, and TCL were invited as the leaders of the QD TV camp to participate in the three major brands. They also shared their respective development and deployment of quantum dot display technology at the site and announced to the market that they would join hands with the industry and channels. The determination to promote the universal adoption of quantum dot technology in television.
At present, quantum dots are mostly used in mid-to-high-end series. After the technology is more mature, the sub-level series are just around the corner. The price can benefit the mass market.
