Color TV giants focus on quantum dot technology, which is a breakthrough

At this stage, OLED TVs have not yet entered the consumer market on a large scale, but more far-sighted TV manufacturers have turned their attention to using quantum dot technology to produce TV displays. For example, Samsung and LG have already used quantum dot displays as an alternative to expensive OLED displays and plan to apply them to the next generation of TV products.

Just as the global color TV manufacturing industry was focusing on the two major Korean brands, hoping that they could make breakthroughs in quantum dot technology, domestic color TV manufacturer TCL took the lead in launching China's first quantum dot TV - TV+ Quantum Dot TV H9700, announcing the beginning of the quantum dot era in the color TV industry.

Quantum dots achieve technological breakthrough

Quantum dots are a kind of cutting-edge nanomaterials, with a grain diameter between 2 and 10 nanometers. Their unique photoelectric properties allow them to emit very pure, high-quality monochromatic light of various colors when stimulated by electricity or light, depending on the size of the quantum dot's diameter.

When applied to the display field, quantum dot technology can emit high-quality red/green monochromatic light with a concentrated energy spectrum and very pure, which completely surpasses the phosphor luminescence characteristics of traditional LED backlights and achieves better imaging colors. Therefore, quantum dot display technology is regarded as the best solution to efficiently improve the color gamut value of color TVs in the future and a weathervane for new technologies in the display industry.

According to market research company Display Search, the shipment of quantum dot TVs will reach 1.95 million units next year, accounting for only 0.8% of the entire market, and is expected to rise to 25.5 million units in 2020. This technology will sweep the global color TV manufacturing industry at a rapid development speed.

What is more noteworthy is that recently, companies such as Samsung, LG, and Apple have stated that they are actively promoting the research and development of quantum dot display technology and applying it to flat-screen TVs and the next generation of mobile smart devices.

Technology companies such as Amazon and Asus are also using quantum dot technology to varying degrees to improve the display quality of their readers and laptop computers.

With the release of TCL quantum dot TV, the international quantum dot display camp has begun to take shape and has surpassed OLED in all aspects of technology. Quantum dot TV will carve out its own blue ocean in the "post-LCD" era.

Quantum dots bring breakthroughs in products

Although the industry generally believed that OLED was the next generation display technology and had high hopes for it, in recent years, due to cost and technical limitations, OLED's performance has been disappointing. The launch of TCL's quantum dot TV has broken the window of innovation in color TV display technology in recent years and completely changed the development direction of color TV display technology.

Chen Guanglang, Chief Technology Officer of TCL Multimedia, said, "The H9700 is not only the first to apply quantum dot display technology and true color display technology, but also equipped with the highest color gamut and resolution screen of CSOT, achieving 110% NTSC color gamut coverage in one fell swoop." At present, the color gamut of OLED on the market can only reach 100% in theory. In comparison, the H9700 has a wider color gamut coverage, more precise color control, and purer red, green and blue, representing the highest level of current color TV products.

According to authoritative test data from the National Radio and Television Product Quality Supervision and Inspection Center, under the NTSC standard, the color gamut of ordinary LED TVs is only 72%, the first-generation high-color gamut TV is only 82%, the second-generation high-color gamut TV is about 96%, and the actual color gamut of OLED TVs is 89%, while the color gamut coverage of TCL TV+ quantum dot TV H9700 is as high as 110%. This data also fully proves the outstanding advantages of quantum dot TVs in picture display.

Lu Renbo, deputy secretary-general of the China Electronic Commerce Association and a well-known home appliance expert, believes that the emergence of quantum dot TVs will undoubtedly put more pressure on OLED TVs. The advent of quantum dot TVs will usher in a major transformation in the color TV display industry, and the color TV market will continue to develop rapidly towards clear and thorough displays.

As quantum dot technology matures, global first-tier TV brands are actively developing large-size quantum dot TV products. Among them, Samsung Electronics plans to mass-produce QD LCD TVs in the first quarter of next year. The first batch of products will mainly be 55 inches and 65 inches, and will be positioned in the ultra-high-end market. LG Electronics has also been working with QD Vision to develop quantum dot backlight technology. In addition, Sony also plans to launch QD LCD quantum dot TV products larger than 55 inches.

On the other hand, in the global TV manufacturing market, display technology is becoming more mature and the technical differences between manufacturers are gradually narrowing. The emergence of quantum dot TVs has also injected an effective stimulant and innovation momentum into the color TV industry. The launch of TCL's quantum dot TV H9700 symbolizes that the color TV industry has taken the first step towards a new product form. We have reason to believe that an industry revolution caused by quantum dot technology is about to begin.
