Quantum dot technology can significantly improve display performance such as color gamut, brightness, and contrast.
Quantum dot display technology
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.
In terms of specific advantages, QD TV's coverage in color gamut, accuracy of color control, and purity of red, green and blue colors have been fully upgraded. It is regarded as the commanding height of global display technology, and it is also considered as a global display technology revolution. . Companies such as TCL, Samsung, LG, and Apple have all indicated that they are actively promoting the development of quantum dot display technology, and companies such as Amazon and Asustek have also adopted quantum dot technology to improve the quality of their products.
According to data from NPD DisplaySearch, the market demand for global quantum dot materials will increase from less than 2.5 million square meters in 2015 to nearly 25 million square meters in 2020, with an average annual compound growth rate exceeding 50%; and the global quantum dot market by 2020. The scale will reach 2.5 billion U.S. dollars, with huge growth potential.
It is worth noting that at the 2017 International Quantum Dot Display Industry Development Forum, Gome, Suning, Jingdong, Tmall, Tangbai, Zhongbai and other channel makers and Samsung, TCL, and Hisense Quantum Dot TV manufacturing enterprises signed a joint The billion-dollar spot TV sales annual bill of 10 billion yuan, a comprehensive layout of quantum dot TV online and offline channels, to promote the quantum dot TV to speed up the popular fast lane.
It can be seen that China's color TV industry has gradually returned to the quality line, quantum dot technology has become the mainstream display technology for color TV products has no suspense, and the continuous improvement of the technology will continue to strengthen the competitiveness of LCD technology camp. Under the high-end trend of color TVs, quantum dot technology will undoubtedly lead the new high-end television industry.
ULED display technology
ULED technology is called Ultra-LED, is China's self-display technology developed and promoted to the industry through 7 years of Hisense. This technology has more than 170 patents, through the backlight multi-zone dynamic control technology, peak brightness control technology and backlight scanning control technology, to lower the cost of the LCD screen display quality to a higher level.
ULED display technology
Multi-zone backlight dynamic control technology
ULED divides the backlight into multiple independent control units, which can accurately adjust the brightness of the corresponding backlight area according to the light and dark distribution of each frame of the image. ULED's first digital-analog hybrid fine dimming, dynamic contrast ratio of 8 million: 1, compared to ordinary 4K TV increased by 3 orders of magnitude, compared to high-end 4K TV increased by 2 orders of magnitude.Adaptive partition peak brightness boosting technology
ULED's first adaptive peak brightness enhancement technology and dark field image detail enhancement technology can analyze the brightness distribution characteristics of each frame of the image, and enhance the peak brightness of the backlight of the corresponding area for the image scenes rich in light and dark levels and highlights in the screen. The brightness can be improved by more than 3 times, and the brightness and darkness of the extended picture can be made more rich in the image level and the three-dimensional effect can be enhanced.
PCR precision color reproduction technology
ULED uses a narrow spectrum high color gamut technology, RGB three primary colors of higher purity, its precise color reproduction technology can carry out adaptive color processing of the picture, to ensure the details of the image color expression and precise reduction.
The outstanding performance of Hisense ULED technology is reflected in its ULED TV, and it has also won several international display technology awards, and has become one of the representatives of cutting-edge display technology.
Laser display technology
From the point of view of colorimetry, the color gamut coverage of the laser display can reach more than 90% of the color space recognized by the human eye, more than double the coverage of the traditional display gamut, completely breaking through the gamut space of the first three generations of display technology. The insufficiency of humanity achieves the most perfect color reproduction in human history, enabling people to see the most authentic and beautiful world through display terminals.
The excellent application of laser display technology on television also won the praise of consumers. Laser TV makes the whole TV picture look more real, layered, and transparent, and the clarity of the picture will also be greatly improved with the increase of color saturation. Since lasers are used as the backlight for televisions, laser televisions can be made thinner for home use. Laser TV also overcomes the discomfort caused by the long-term viewing of the fluorescent colors produced by the human eye, and it does not radiate to human eyes.
And at an optimal viewing distance of 4m to 4.5m, the 30° angle of view presented on the screen allows the muscles of the eye to relax naturally. The reflected light of the laser emitter is used on the screen, which is almost the natural observation mode of the eye. It is comfortable, natural and does not hurt the eyes. . According to relevant international standards, laser-based television products are the only display products in the world that fully satisfy theoretical visual requirements and are harmless to the naked eye.
