JBD Unveils the Roadrunner I Projector
Global leader in MicroLED microdisplay technology, JBD, has made waves with the launch of the "Roadrunner I" polychrome projector. This product is the first of its kind in the new "Roadrunner" series and is set to redefine expectations in the realm of augmented reality (AR) displays. With significant advancements in pixel size and optical efficiency, the Roadrunner I enhances the user experience and paves the way for consumer-grade full-color AR smart glasses.
Revolutionary Pixel Technology
At the heart of the Roadrunner I is a cutting-edge MicroLED microdisplay panel featuring a pixel pitch reduced to an astonishing 2.5?m, down from 4?m in the previous "Hummingbird" series. This reduction marks a major evolution in the MicroLED microdisplay field, significantly boosting image quality. With a pixel density soaring to 10,160 PPI, the Roadrunner series ensures a vivid visual experience.
Exceptional Visual Performance
The Roadrunner I boasts a 25-degree field of view (FOV) and an angular resolution of up to 32 pixels per degree (PPD), achieving over a 20% improvement from earlier models. This enhancement allows for sharper detail reproduction, minimizing graininess and offering a refined image quality. Moreover, the projector features an ultra-high refresh rate of 480 Hz, effectively preventing flicker and judder, which is essential for dynamic content.
Innovative Optical Engineering
Along with impressive pixel density, the optical architecture of Roadrunner I has been meticulously redesigned. With a limiting spatial frequency of 200 lp/mm, the modulation transfer function (MTF) achieves an admirable 0.4 at the field's center, combined with a contrast ratio of 100:1. This capability to address high-frequency image details results in sharper and more nuanced visuals, marking a substantial leap forward in visual quality.
Compact Design and Enhanced Functionality
The reduced pixel pitch allows the Roadrunner I to excel in miniaturization. Engineered with an X-cube architecture, it achieves a compact volume of just 0.2 cubic centimeters and a weight of merely 0.5 grams. Compared to the "Hummingbird I," which shares a similar resolution of 640x480, both dimensions are reduced by about 50%. This advancement positions the Roadrunner I as one of the lightest and most compact polychrome projectors, creating more opportunities for the design of lightweight AR / AI smart glasses.
Optimized Light Engine Architecture
The projector also features an extensively optimized light engine design, cutting the overall optical path length down to 7.8 mm—a 35% decrease from the 11.99 mm path seen in the "Hummingbird I". This compact design dramatically minimizes the space required around the eyeglass hinge, becoming crucial for manufacturers of user-friendly, aesthetically pleasing full-color smart glasses.
Despite its compact size, the Roadrunner I excels in performance, delivering luminous flux of up to 3.2 lumens with a mere 90 mW of power consumption, which showcases its outstanding energy efficiency. This is achieved by employing a 22-nm backplane process that reduces backplane consumption to just 18 mW, coupled with ongoing R&D at JBD aimed at boosting emission efficiency for ultra-small pixels.
Setting a New Standard in Projectors
When compared to traditional AR light engines like LCoS, the Roadrunner I stands out across various crucial metrics: pixel size, volume, weight, contrast ratio, refresh rate, and power consumption. JBD has officially made this innovative projector available for customer sampling, further solidifying its place as a leading option for ultra-lightweight, full-color AR smart glasses.
Vision from JBD's CEO
JBD's CEO, Li Qiming, expressed enthusiasm about the launch, stating, "Roadrunner I marks a pivotal exploration and breakthrough at the frontier of MicroLED microdisplay pixel scaling." He emphasized how the ultra-compact design facilitates lightweight form factors while the high angular resolution sets new visual fidelity standards, enhancing consumer-grade AR smart glasses.
