At present, the display technology and industry have reached the stage of upgrading and reshuffling, LCD tends to be saturated, OLED, QLED, Epaper, 3D and other display technologies compete to develop to open up the characteristic market. On December 1, at the 2022 World display Industry Conference, Xu Zuyan, academician of the Chinese Academy of Engineering, said that laser display has the advantages of narrow spectrum, high brightness and high cost performance, and is bound to become the mainstream of the next generation display industry.

The development direction of the display industry is to move towards the resolution limit of human vision. In the era of ultra-high-definition display, the goal of display technology is to achieve the international standard of BT ·2020 ultra-high-definition television, meet the three standard elements of 4K / 8K high resolution, more than 70% large color gamut coverage, and reach the large color number of 12bit, and achieve high simulation video image reproduction. Xu Zuyan said that the laser display uses red, green and blue lasers as light sources to regulate the intensity ratio, temporal and spatial distribution of intensity and total intensity of the tricolor laser to achieve high fidelity reproduction of panchromatic video, with the characteristics of narrow spectral width, high brightness, and good directivity.

Specifically, in terms of brightness, the laser display has high brightness, which can be accurately controlled in the best visual perception area of the human eye, and it is easy to achieve 8K high resolution and high contrast. In terms of color, the laser display spectrum is narrow, the chromaticity triangle area is large, the coverage of the large color gamut is more than 70%, and the 12bit color coding is not overlapped. In terms of performance-to-price ratio, laser display has a high performance-to-price ratio, 50% lower power consumption than LCD TV, a life span of more than 50,000 hours and a light weight. From the perspective of industrial chain, laser display has 40 enterprises in the country and launched a series of products. In 2020, the domestic and foreign sales of the laser display industry exceeded 40 billion yuan, with an average growth rate of more than 100%.

"Laser display can fully meet the BT 2020 ultra-high definition display standard, in line with the development direction and trend of the display industry, and will become the mainstream of the next generation display industry." Xu Zuyan said that laser display and other display technologies will create a huge market of hundreds of billions of dollars per year.

The main market of the next generation display industry is information dissemination and video entertainment. C end is large screen, super-large screen TV, home theater, computer, game console screen, B side is telemedicine, distance education, remote conference and so on. At present, various display technologies are actively developing their own characteristic markets.

According to Xu Zuyan, liquid crystal display (LCD) focuses on the development of television, computer and other fields, devoting itself to the development of new materials, new processes and new systems to achieve industrial upgrading. Organic light emitting display (OLED) focuses on the development of mobile phone screen, wearable and other display industries, as well as the development of flexible display and transparent display market. Quantum dot display (QLED) is intended to explore environment-friendly electroluminescent QLED technology and develop the corresponding characteristic market. Light-emitting diode display (LED) expands existing industries such as indoor and outdoor large-screen information display to improve the clarity and viewing comfort of entertainment / viewing applications. E-paper display technology continues to develop the e-book market. 3D display can improve the comfort of parallax 3D viewing and explore the true 3D display based on holographic principle and light field principle.

"the whole chain of theory, experiment, technology and industrial demonstration has proved that the three characteristics of laser (narrow harmonic width, high power and good direction) ensure that only laser display can fully realize the three elements of BT.2020 ultra-high definition display standard, and laser display will become the mainstream of the next generation display industry." Xu Zuyan said that the laser display also provides a huge space to expand the C-end and B-end market of the display industry.
