As a fourth-generation display technology after black-and-white display, color display, and digital display, laser TV is gradually entering the general consumer family. Compared to traditional LCD TVs, laser TVs have a brighter color and a longer life. As a new high-tech product, laser TV has attracted more and more attention from ordinary consumers.
It is reported that the team of Ning Yongqiang, a researcher in the light room of Changchun Institute of Optics, Fine Mechanics and Physics, Chinese Academy of Sciences, has independently researched and developed some of the core technologies of laser TV. The “Made in China” laser TV is getting closer and closer to thousands of households.
The core technology of green laser pointer TV is red, green and blue. Due to the complex structure of the laser, there are extremely high requirements for materials quality, stress control, laser packaging and other technologies. For a long time, laser R&D and manufacturing technology has been used in Japan. The monopoly of Germany and other countries, the price of laser TV has always remained high, making domestic laser TV has become the goal of researchers in related fields.
In the past two years, Ning Yongqiang teamed up with Shenzhen Ruibo Optoelectronics and Shandong Huaguang to form a joint research group, which has successfully developed a number of key technologies such as high-efficiency thermal management technology, laser beam shaping technology and high-power red light chip. The first 8-watt fiber-optic coupling module based on the independent 638 nm red LD chip in China means that Chinese researchers have partially broken through the core technology of laser TV.
