JBD (Jade Bird Display) unveiled its “Hummingbird” polychrome MicroLED projector at SID which is already in mass production since May 2023. This revolutionary product incorporates JBD’s cutting-edge MicroLED display panels which just won the SID “2023 Display of the Year” award. The Hummingbird features lightweight, ultra-compact form factor, ultra-high brightness, vivid and saturated colours and best-in-class energy efficiency. These advantages make Hummingbird projectors the best-available full-color solution which would significantly improve user experience in smart glasses and consumer AR applications.
The JBD Hummingbird stands out as the world’s smallest and lightest projector, boasting a volume of 0.4cc and weighing just 1.0 gram. This ultra-compact size allows for seamless integration into the temples of smart glasses and other AR applications, significantly reducing weight and volume.
With a luminous flux output ranging 3-5 lumens, the JBD Hummingbird offers a standard viewing angle of 30?, which can be customized within the range of 25? to 45?. Coupled with a decent optical waveguide, it achieves an impressive brightness of 1800 nits, ensuring clear visibility of screen contents even in bright outdoor environments. When it comes to battery life, the JBD Hummingbird benefits from the high luminous efficacy of JBD’s MicroLED technology. Under typical operating conditions, the projector’s power consumption can be as low as 260 mW, significantly lower than other microdisplay technologies currently available in the market like LCOS or DLP. This remarkable power efficiency effectively extends the battery life of AR glasses, catering to all-day usage in varying ambient lighting conditions.
