This company releases a new MicroLED color optical module for AR: brightness up to 6000nits

For a long time, visual defects such as insufficient brightness and poor image quality have hindered the application and popularization of full-color optical waveguide AR glasses. JBD said that the brightness of the new Hummingbird I color optical module reaches 6,000 nits, far exceeding the 1,500 nit brightness level of previous AR optical waveguides. Currently, JBD has begun to provide module development kits to accelerate the pace of innovation in the AR ecosystem.

The team also provided a real outdoor picture of the "Hummingbird I" color optical module:

The brightness of outdoor grass is about 1,500 nits, so the 1,500 nit brightness of the previous optical waveguide cannot guarantee the readability of text. With the brightness increased to 6,000 nits level, this ensures that AR glasses can provide clear and vivid visual perception in various outdoor light conditions.

The company pointed out: "This brightness performance is attributed to JBD's continuous breakthroughs in MicroLED luminous efficiency. The brightness of the red, green and blue micro-display panels has been greatly improved, while providing Hummingbird I with a luminous flux output capability of up to 6 lumens. This technological breakthrough has increased the luminous flux of Hummingbird I by up to 100% at the same power consumption level, and has become the key to achieving high-brightness display."

In addition, JBD’s optical waveguide image quality correction solution ARTCs has greatly improved the visual experience of the new module. The support of ARTCs further eliminates color distortion and graininess, greatly improves display uniformity, and achieves global brightness uniformity >80% and color difference ΔE 0.02.

JBD stated that the new Hummingbird I color optical module provides system-level advantages for the overall architecture of AR glasses:

1. Highlight display, 6000 nits eye-catching brightness, easily copes with high-brightness environments, providing an unconstrained visual experience in the entire scene;

2. Excellent picture quality, better picture uniformity and better color performance, giving diffractive optical waveguides a look and feel comparable to arrayed optical waveguides;

3. Longer battery life, the light engine is more efficient, and the energy consumption ratio is better. The typical power consumption is only 150 milliwatts, and longer battery life can be achieved with the same performance or battery capacity;

4. Comfortable to wear, LCoS and DLP require larger volume and higher power consumption at the same brightness level, while Hummingbird I is only 0.4 cubic centimeters, providing huge improvements in the wearing comfort and design flexibility of AR glasses.Space for innovation.
