JBD micro LED supplier JBD has launched a light machine called “Hummingbird” at SID 2023 (IT Home Note: for AR smart glasses display module), whose core micro LED microdisplay was previously awarded the 2023 “Display of the Year” award at this year’s SID. “The light machine is equipped with a 0.13-inch RGB display and will start mass production in May.
The company’s website is a source of information.
According to JBD, Hummingbird is the smallest and lightest light machine, with a volume of 0.4cc; a weight of 1.0g; a standard field of view of 30°, and supports 25°~45° field of view customization. In D65 white balance state, it can output 3~5 lumens of luminous flux with a high-quality light waveguide to achieve 1800 nits of brightness to the eyes; in terms of image quality, it supports 8bit colour depth and 16.77 million colours full true color display, which provides more possibilities for lightweight AR glasses.

However, in addition to the issues of mass production and stability, the brightness uniformity of Micro LEDs in AR glasses is a major concern. This problem is made more difficult by the inconsistent brightness of the three-colour panel, so there may be some compromises on brightness uniformity in the X-cube solution as well.
The company’s newest product, the “Hummingbird”, is the world’s smallest and lightest micro LED for AR glasses.
The current optical machine products incorporating Micro LED technology can have the advantages of high brightness, high resolution, high energy efficiency and low power consumption, which is the future direction of AR glasses display technology. However, at present, the development and production of Micro LED technology is more difficult, so the cost is also quite high.
