At present, the display technology and industry have reached the stage of renewal and reshuffle, LCD tends to saturate, and OLED, QLED, Epaper, 3D and other display technologies are competing to develop and open up special markets. It will become the next generation of the display industry.
The development direction of the display industry is 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 TV, which meets the three standard elements of 4K / 8K high resolution, large color gamut coverage of more than 70%, and large color number of 12bit to achieve high simulation video image reproduction. Xu Zuyan said, a laser display with red, green and blue laser as the light source, regulates the intensity ratio, intensity distribution and total intensity of the three laser colors to achieve full-color video high-fidelity reproduction, with a narrow spectrum, high brightness, good directionality and other characteristics.
Specifically, in terms of brightness, the laser display brightness is high and can be precisely controlled in the best visual perception area of the human eye, making it easy to achieve 8K high resolution and high contrast. In terms of color, laser display has a narrow spectral width and a large chromatic triangle area, which can achieve a large color gamut coverage of more than 70% and 12-bit color coding without overlap. In terms of cost performance, laser display has a high-cost performance, compared to LCD TV power consumption is reduced by 50%, life expectancy of more than 50,000 hours, and lightweight. From the industry chain, laser display in the country has 40 enterprises, that launched a series of products, laser display industry in 2020 had domestic and international sales of more than 40 billion yuan, 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, will become the mainstream of the next generation display industry.” Xu Zuyan said, laser display and other display technologies blossom and 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 appreciation entertainment. c-end is a large screen, super large screen TV, home theater, computer, game console screen, the bend is telemedicine, tele-education, teleconference, etc. At present, various display technologies are actively developing their own characteristics of the market.
According to Xu Zuyan, liquid crystal display (LCD) focus on the development of television, computer and other fields, dedicated 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 cell phone screens, wearable and other display industries as well as the development of flexible display, and transparent display markets. Quantum dot display (QLED) is intended to explore environmentally friendly electroluminescent QLED technology and develop the corresponding characteristic market. Light Emitting Diode (LED) displays are expanding into existing industries such as indoor and outdoor large-screen information displays, aiming to improve clarity and viewing comfort for entertainment/viewing applications. E-paper display technology continues to develop in the e-book market. Three-dimensional displays can improve parallax three-dimensional viewing comfort, and explore the true three-dimensional display based on holographic principles and light field principles.
“Theory, experiment, technology and industry demonstration of the whole chain proved that the three characteristics of laser (harmonic width narrow, high power, good directionality) to ensure that only laser display can fully realize the three elements of BT.2020 ultra-high definition display standard, laser display will certainly become the mainstream of the next generation display industry.” Xu Zuyan said that laser display also provides a huge space to expand the C- and B-side markets of the display industry.
