JBD’s red microLED brightness exceeds 1 million nits
MicroLED manufacturer Jade Bird Display Ltd. (Shanghai, China) has announced that the brightness of its 0.13-inch red MicroLED chips has exceeded 1 million nits, setting a record high.
Since its founding in 2015, JBD has pursued using multiple materials for microLED displays with AlGaInP for red LEDs.
JBD’s red microLED brightness is the result of advanced epitaxial material growth, non-radiative recombination suppression and the use of beam-shaping technolog, the company said. JBD’s microLED pitch is 4 micron while the emitter size is less than 2 micron.
Advances in pixel optics also plays a key role in brightness engineering. The structure used in the 0.13-inch microLED increases light extraction by use of a transmission film system. It also has an enhanced microlens that improves collimation and brightness.
JBD’s red microLED performance was at 300,000 nits in 2021, 500,000 nits in 2022 and 750,000 nits in February 2023.
The red brightness milestone brings JBD’s “Hummingbird” X-cube polychrome projector to a new level. With its 0.4 cubic centimeter size, 1 gram weight and 200mW low power consumption, the Hummingbird is suitable for consumer AR displays (see JBD offers small-but-bright microLED projector).
The Hummingbird can now boast 1 million nits blue, 5 million nits green display, and 1 million nits red for an output flux of up to 5 lumen.
