"Remote high-frequency vibration phosphor" technology breakthrough laser display light source

China Education Equipment Purchasing Network News: Recently, from the thirteenth session of the Hi-Tech Fair, it was learned that the “remote high-frequency vibration (rotation) phosphor” technology developed by an enterprise in Shenzhen has broken through the bottleneck of laser display technology and can greatly reduce the laser display. The production cost of the product.

Laser display light source is the internationally recognized fourth display light source, which has the advantages of ultra-high brightness, wide display color gamut (full color), high-definition display, energy saving and environmental protection. The “remote high frequency vibration (rotation) phosphor” technology independently developed by Shenzhen Guangfeng Optoelectronics Technology Co., Ltd. and having independent intellectual property rights, developed by a multimode blue laser combined with an original high frequency vibration (rotation) phosphor module It is the world's first light source for a new type of laser display. The light source uses a blue laser as the energy source, and the multi-color rotating phosphor containing red, green phosphors and blue translucent glass slides is a light wavelength converter, which produces red, blue and green primary colors. The technical principle is completely different from traditional lasers. Display technology.

According to Li Yi, general manager of Shenzhen Guangfeng Optoelectronics, the use of multiple blue lasers focused on a phosphor coating makes the optical power in the 1 square millimeter light spot range reach more than tens of watts. This optical power density is higher than the current The brightest LED reported is an order of magnitude higher. Using this technology in high-end home theater products, you can use 50 lasers to achieve 5000lm brightness projection display.

After visiting the invention, Academician Jin Guofan from Tsinghua University stated that the technology is original and has good efficiency, cost and stability.

This technology has been successfully used in many product fields such as mini projectors, stage spotlights, and large-screen screen walls. Li Yi believes that after future revisions and improvements, this technical product can be fully mass-produced. For example, this technology can be applied to a large-screen TV, and a "movie theater" that is power-saving, environmentally friendly, high-definition, and has a large and thin screen size can be moved to the home.

It is understood that the “remote high-frequency vibration (rotation) phosphor” technology has formed a patent pool with core patented technologies and covering nearly one hundred patented technologies. (Organized by China Educational Equipment Purchasing Network)
