Some core technologies of domestic laser TV have been breached, and laser TV is one step closer to thousands of households

As the fourth-generation display technology following black-and-white display, color display, and digital display, laser TVs are gradually entering ordinary consumer homes. Compared with traditional LCD TVs, laser TVs have more vivid colors and longer service 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-emitting room of the Changchun Institute of Optics, Fine Mechanics and Physics, Chinese Academy of Sciences, has independently developed and overcome some of the core technologies of laser TVs.

The core key technology of laser TV is the red, green and blue lasers. Due to the complex structure of the laser, it has extremely high requirements for material quality, stress control, laser packaging and other technologies. For a long time, the research and development and manufacturing technology of lasers have been adopted by Japan, Germany and other countries monopolize, and the price of laser TV has always been high. Making domestic laser TV has become the goal of scientific researchers in related fields.

In two years, Ning Yongqiang's team, together with Shenzhen Ruibo Optoelectronics, Shandong Huaguang and other units, formed a joint research group, which has overcome many key technologies such as high-efficiency thermal management technology, laser beam shaping technology, high-power red light chip, etc., and has successfully developed The first 8-watt fiber-coupled module based on the independent 638-nanometer red LD chip in my country was released, which means that Chinese researchers have partially broken through the core technology of laser TV.
