The hottest year 2020 and 2025 will be led by lase

From 2020 to 2025, laser display technology will lead the "mainstream" of the next generation display market. On the afternoon of the 26th, Mr. Xu Zuyan, a famous Chinese laser technology expert, professor level senior engineer of the Institute of physics of the Chinese Academy of Sciences and academician of the Chinese Academy of engineering, who participated in the "academician expert's trip to Ningbo", made a report on "laser TV - next generation TV" at the new materials forum

laser TV: the highest state of TV technology

"laser is also a kind of light. It is a kind of monochromatic light generated according to Einstein's principle of stimulated radiation. Compared with general light, it has three characteristics: first, it has particularly good monochromaticity, second, it has particularly good directivity, and third, it has particularly high brightness." As a laser expert, academician Xu first explained the characteristics of laser to everyone as soon as he took his seat

"people's pursuit of beautiful visual effects promotes the development of TV technology." Academician Xu Zuyan also talked about the development history of TV as if he were a treasure: "black and white TV appeared in the 1930s; color TV appeared in the 1950s; digital TV appeared at the end of the last century, which is the third generation of TV, which solved the problem of clarity; laser TV appeared at the beginning of this century, which is the fourth generation of TV, which solved the problem of color. While the fifth generation of TV is holographic 3D TV, which can realize true 3D through holographic technology."

the three characteristics of laser, such as good directivity, good monochromaticity and high brightness, are the basis for laser TV to achieve high fidelity images. The goal of TV technology development is to reproduce high fidelity images. High fidelity images have three elements: dual HD, large color gamut, and true 3D. Laser TV can raise the three elements of TV to the limit of human eyes, which can be said to move towards the highest level of TV technology. Its geometric resolution will be increased by more than 9 times, the number of colors will be increased by more than 4000 times, the color gamut coverage will be increased by more than 3 times, the color saturation will be increased by more than 8 times, and the parallax 3D will become 3D

"laser TV is the best way to achieve high saturation and large color gamut TV." Academician Xu said that the color gamut coverage of laser TVs is much higher than that of existing color TVs. Therefore, when watching laser TVs, the colors perceived by human eyes are three times richer and three times brighter

industrialization of laser TV is written into "made in China 2025"

academician Xu said that the world has already begun the industrialization development of laser TV. 5. Transmission system: there are two important types of transmission of electronic universal experimental machine. 1. Circular arc synchronous gear belt fine lead screw pair transmission; 2. Popular belt drive, major TV enterprises have developed laser TV prototypes. Other domestic units are still in the research and development stage of hybrid light source laser TV, but the Chinese Academy of Sciences is ahead in the research and development of laser TV. In March, 2015, the Institute of physics and chemistry of the Chinese Academy of Sciences successfully developed a 100 inch three primary color LD laser TV, which opened the way for the industrialization of laser TV, and achieved mass production and sales in 2017, with an annual production capacity of 30000 sets. In 2016, the three primary color LD super large screen seamless splicing laser TV prototype developed by the Institute of physics and chemistry of the Chinese Academy of Sciences participated in the Shanghai Industrial Expo. The Institute of physics and chemistry has also jointly developed an ultra-high brightness laser TV with China Science Aurora, which can be used in digital cinemas and large screen public command centers

Xu Zuyan introduced that the industrialization of laser TV has been written into the "made in China 2025" plan, and the Ministry of science and technology has launched the key research and development plan of laser TV during the 13th five year plan, for which the state has also allocated 240million yuan

Xu is a new factory for coloring and modification of plastics. Academicians predict that the three primary color LD technology will make a breakthrough in about 5 years, and the laser TV will move from experimental prototype to large-scale products in about 10 years. China will form a complete technological innovation chain in 2020, build a laser TV production demonstration line in 2025, and form a laser TV scale industrial cluster in 2030

the annual market capacity reaches 100 billion dollars

academician Xu believes that the laser TV industry has broad prospects, and the annual market capacity reaches 100 billion dollars. At present, there are six major markets for laser TV: one is super large screen/large screen, the other is home film and television/TV, the third is office projection/micro projection, the fourth is computer screen/game console, the fifth is projection/personalized display, and the sixth is true 3D display

"with the reduction of cost and the improvement of cost performance, laser TV will enter the homes of ordinary people." Academician Xu said that laser TV is a disruptive technology and the best choice for the new generation of TV industry. The whole world is carrying out the industrialization research and development of laser TV, striving to achieve the next generation of TV industry first and occupy the TV market of photoelectric industry. China's level is equivalent to that of the world, and it is entirely possible to seize this historical opportunity to accelerate the industrialization of China's laser TV through independent innovation and no longer be controlled by others

"China is a big TV manufacturing country, but 50% - 80% of the benefits are collected by foreign investors every year, which is very passive." Speaking of this industry pain point, Xu Yuan, who is nearly 80 years old, suddenly raised his voice by providing advanced equipment and production lines for intelligent manufacturing, digital manufacturing and network manufacturing. He said that he hoped that the whole industry would unite to use laser technology to develop Chinese people's own TVs and let Chinese people watch their own TVs. "Let's work together to realize the Chinese dream of 1.3 billion Chinese watching Chinese TV." Academician Xu accentuated his tone again

laser technology is widely used

according to the speed specified in gbt228 standard, let the experimental machine carry out the tensile, tensile strength, yield strength and elongation of metal tensile samples. Academician Xu introduced that the earliest application of laser is mainly to apply its good directionality. After the invention of laser in the 1960s, it was soon used to measure the moon. The laser emission was reflected back to accurately measure the distance between the earth and the moon, which promoted laser ranging. For example, the docking of spacecraft is also through laser, which can accurately measure the three-dimensional distance between the two spacecraft. There are also some applications in aircraft, and even now it has been developed into laser imaging radar

the two characteristics of laser, good directivity and monochromaticity, can also be used for communication. As we all know, a great thing in the last century is optical fiber communication. In addition to optical fiber communication, free space communication can also be used. In recent years, quantum secure communication has emerged, which also uses lasers

laser has many uses in other aspects, such as ophthalmic treatment. If the fundus retina has lesions, or the retina falls off, welding the retina with a yellow laser is not easy to cause accidents. There is also minimally invasive treatment of prostate. In the past, surgical treatment required hospitalization, and the use of strong lasers, such as green 100 watt strong lasers, is equivalent to minimally invasive surgery, with relatively small trauma. The effect of using blue laser to check cancer and red laser to treat it is also very good. If you irradiate cancer cells with red laser, the killing power to normal cells is relatively small, and the killing power to destructive cancer cells is relatively large. At the same time, the intensity of laser can also be used in processing. For example, the application of thousands of watts of laser for automobile welding has been very common. For example, some welding and processing on drilling machines, aircraft and spacecraft may use high-power lasers

what is laser TV

laser TV is composed of a laser light source projector and a projection screen using reflective ultra short focus projection technology, which can also show a good picture in a high brightness environment
