At the closing ceremony of the 24th Winter Olympic Games, the chief director drew on the uniquely Oriental allusion of "presenting willow branches as a farewell", hoping that all friends who came to Beijing would take this willow branch with them as a token of the Chinese people's friendship. Meanwhile, a towering tree composed of "True Laser" beams, full of vitality, stood in the center of the stage. It passed through the snowflake torch platform and reached straight to the sky, representing the most simple and sincere human emotions: farewell, memory, remembrance, and expectation. This tree made of light beams is backed by the "True Laser" technology, which has been studied by two generations of Chinese scientists for more than 40 years. The technology uses three-primary-color lasers as the light source and, through advanced architectural processes, achieves high-fidelity reproduction of images, fully meeting the BT.2020 standard. "'True Laser' has achieved mass production in engineering projection, home theater, digital projection, and other fields, ushering in the 'Laser Display 2.0 Era'," said Bi Yong, a scientist who participated in the research and development of "True Laser" and promoted the industrialization of this technology. Achievements: Five "True" Experiences The application of "True Laser" display technology can bring audiences five "True" experiences that are hard to achieve with liquid crystal displays and laser phosphor displays: true color, true brightness, true companionship, true energy efficiency, and true reliability. The "True Laser" light source is pure with narrow spectral bandwidth and other characteristics, achieving a color depth of 10bit and a color expression capability of 1.07 billion colors. Higher color depth can increase the resolution of the picture in a three-dimensional sense, bringing smoother color transition performance. Especially when displaying halos, the color transition around the light source will be more natural. "True Brightness" achieves ultra-high brightness. In addition, due to the higher spectral purity and better color saturation of "True Laser" display, under the same physical brightness, the human eye's subjective sense of brightness for "True Laser" display will increase by 20-30%, making the picture clearer. Different from the锯齿状 attenuation of other display technologies or the landslide-like attenuation after the life cycle, the brightness of "True Laser" remains at about 80% of the initial brightness after 30,000 hours of service life. In the process of light transmission, "True Laser" display adopts "fiber coupling" technology, which has the advantages of high transmission efficiency and high reliability, and is not affected by changes in external environments such as impact, vibration, and temperature. "What is particularly worth mentioning is 'True Energy Efficiency', that is, ultra-low energy consumption, which is also in line with the concept of 'Green Winter Olympics'," Bi Yong said. Compared with other technical routes of mixed light sources, the "True Laser" technology has a light efficiency of up to 17.8 lm/w. Coupled with efficient thermal management technology, it can truly achieve high brightness and low energy consumption, standing firm for the "Green Olympics" until the end. Yu Hong, director of the Technology Department of the Beijing Organizing Committee for the 2022 Olympic and Paralympic Winter Games, previously stated that the promotion of "Scientific and Technological Winter Olympics" has two goals: one is to use new technologies to support the preparation and holding of the Beijing Winter Olympics, and the other is to provide a display scene for the application of new technologies. Bi Yong and other researchers responded to this goal by continuously adjusting the product status according to the creativity and needs of the director team. He revealed that the products used in the closing ceremony of the Winter Olympics must withstand extreme cold weather of minus 30 degrees Celsius, and the researchers stayed in the ice warehouse all day for this purpose. They hope to let more people understand, trust, and enjoy the achievements of "True Laser" technology. The upsurge of scientists' entrepreneurship is constantly surging, and at the same time, there are worries. Moving from the "ivory tower" to the market, can scientists who are used to long-term investment and research adapt to the business rules that emphasize efficiency, certainty, industrialization, and replicability? Bi Yong recently talked about the "difficulties" and "solutions" of scientists' entrepreneurship in an interview, hoping to provide reference for more people. Key: The Pursuit of Transformation of Scientific Research Achievements In 2015, the Technical Institute of Physics and Chemistry of the Chinese Academy of Sciences hoped to transform the laser technology achievements and established a transformation platform "China Aurora". Bi Yong was not only responsible for product development but also undertook some sales and financing tasks. "Transforming from engaging in scientific research in a laboratory environment to product development in a company environment, there have been great changes in goal orientation and logical thinking," Bi Yong recalled. "Carrying out product research and development work on 'True Laser' needs to consider market demand, and issues such as product definition, customer groups, and consumption habits are all new to scientists." The "value recognition" of the transformation of "True Laser" scientific research achievements prompted Bi Yong and others to complete the identity transformation. He said that in the field of laser display, China has the opportunity to realize the localization of core components, which will be a historic breakthrough. In order to complete the transformation of scientific research achievements, Bi Yong led the team to decompose the "gap" in thinking and cognition into executable tasks. "When facing some so-called 'difficulties in transformation', we will take them as necessary knowledge to realize our ideals, take the initiative to learn and adapt, and feel very rewarding." Standard: Making Certain Compromises at the Technical Level The transformation of "True Laser" display technology from laboratory achievements to products has gone through a long process, including customer demand exploration, sample development, trial use, modification and improvement, small-batch trial production, inspection, and other links. In this process, the R&D team found that the market demand for products does not completely match the pursuit of scientific research. For example, from a scientific perspective, the larger the color gamut space of laser display, the better. However, customers' pursuit of color gamut is not absolute. In other words, while customers expect products to have a large color gamut, they also hope to achieve low energy consumption, high efficiency, long service life, and high reliability. Bi Yong analyzed that entrepreneurs with a scientific background must learn to face market demand and make some compromises at the technical level. Taking "True Laser" as an example, it has not only been applied in major occasions but also formed market applications in fields such as laser TV, business projection, and cinema upgrade solutions. Experience: From a Disciplinary "Expert" to a "Jack of All Trades" Looking back on his past experience, Bi Yong summarized three experiences for scientists' entrepreneurship. The first is the transformation of the "evaluation system". If scientists want to start a business oriented to the market, they must adjust their self-evaluation system. "Scientists are often persistent and have particularly firm will, which are excellent qualities in scientific research. But when facing the market, these excellent qualities may become obstacles," he said. Secondly, when scientists transform into enterprise managers, they need to accumulate corresponding knowledge reserves, including laws and regulations, finance, capital markets, etc., transforming from "experts" in a certain discipline to "jack of all trades". Thirdly, we should form an entrepreneurial team with a more open mind. "Scientists may have shortcomings in production quality management, supply chain management, product sales, enterprise operation, etc. By forming a team, we can give full play to each other's strengths," he said. Bi Yong said that behind key popular tracks such as artificial intelligence, autonomous driving, and cloud computing, there are scientists. A large number of cutting-edge and frontier scientific research achievements will move from the laboratory to social life. It is hoped that more entrepreneurs with a scientific background will accelerate the process of advanced scientific research achievements promoting social development to the greatest extent, so that scientific research can benefit the national economy and human life.
