Key Building Blocks of Our Display Architectures

Our transparent displays are built on advanced Volume Phase Holograms (VPHs) designed and engineered in-house.

01

The VPH Film

High-efficiency multiplexed holographic films embedded in the optical combiner enable multiple complex optical functions while maximizing light transfer efficiency.

02

The Combiner Architecture

Leveraging these films as primary building blocks, we have developed proprietary display architectures. By integrating industry-proven optical components we've created a flexible architecture that scales from lightweight AI eyewear to high-performance immersive AR.

Applications & Advantages

01

High-Performance Immersive AR Displays

Our architecture enables the next generation of spatial computing, from private virtual workspaces to outdoor navigation. By combining ultra-high optical efficiency with a wide field of view, our VPH optics deliver vivid imagery in any lighting condition while maintaining maximum transparency for a natural view of the world. Our design ensures minimal forward light leakage, providing the privacy required for sensitive data without compromising the sleek aesthetic of high-end eyewear.

Discrete Displays for AI Eyewear

Ultra-efficient, high-transparency optics make our technology the ideal platform for discrete AI assistants. We enable non-invasive notifications and corner-of-eye displays that maintain the look of natural eyewear while providing the extreme power efficiency required for true all-day battery life. It is the perfect balance of constant connectivity and social acceptance.

03

Ultra-Efficient Displays for Transparent Surfaces

Beyond eyewear, our versatile VPH technology transforms any surface from smartwatches to automotive glass into a functional transparent display. By leveraging scalable, polymer-based components, we enable high-contrast holographic interfaces on ultra-thin surfaces where traditional display technologies cannot integrate. Our solution is designed for high-volume manufacturability and seamless integration.

Why AlphaLum VPH?

Traditional SRG-based Waveguides

  • Low optical efficiency (a few %)
  • Visible forward light leakage ("eye glow")
  • FoV-constrained by material index, forcing reliance on exotic materials for high FoV
  • Compromised see-through quality due to diffraction artifacts
  • Flat waveguides require additional curved optics to meet visual performance standards
  • Reliance on exotic materials introduces complex, cost-intensive manufacturing limiting scalability

AlphaLum VPH

  • 10× higher optical efficiency
  • Extremely low forward light leakage
  • Up to 90° field of view
  • Highly transparent and unobstructed see-through quality
  • Sleek wearable design
  • Scalable polymer-based manufacturing
