JBD is helping Smart Glasses lead the consumer market

JBD has built complete lines for MicroLED micro-display development by possessing independent IC design, MOCVD epi growth, hybrid-integration technology, packaging, testing, driver design and optical modules. With tremendous technology investment, JBD continues to innovate and rapidly grow into a benchmark enterprise in the rising display industry.

AlGaInP is the most mature semiconductor material for red LEDs. It is widely adopted in commercial lighting and display fields with advantages of low cost, high brightness and excellent reliability. However, due to the "size effect", the efficiency of AlGaInP-based MicroLED is reduced by an order of magnitude when approaching micrometer scale, becoming a generally recognized problem in the industry. However, with extensive R&D efforts, JBD has achieved some exciting breakthrough in addressing the issue with size effect. With the latest generation of red MicroLED displays JBD has managed to break their own industry record in terms of light efficiency and brightness.

As reported, to increase red efficiency, JBD manages to redistribute the local charge carriers by a breakthrough in surface treatment process and in this way, minimize the surface non-radiative recombination and boost the efficiency. With the same power consumption, the panel brightness increases remarkably from 500000 nits to 750000 nits, while maintaining excellent reliability as always. It is mentioned that JBD expects to implement this technology in mass production by middle of 2023 and also in their ultra-compact polychrome engine with a volume of only 0.4cc.

The 0.4cc polychrome projector is JBD's highlighted product this year and will be unveiled to the public at SID Display Week in Los Angeles, USA, in May. The polychrome projector is only 0.4cc (cubic centimeters) in size and weighs only 1.0 grams, but it can output more than 4 lumens of luminous flux. The standard field of view of the polychrome projector is 30°, but angle of between 25° and 45° is optional. Coupled with high efficiency waveguide (>500 nits/lm), the glasses incorporating this projector will provide ultra-high brightness of 2000 nits to the eye, with the polychrome projector consumes as little as 260 milliwatts, enabling all-day use of Smart Glasses.
