Smart glasses are moving rapidly from concept to everyday reality. Lighter designs, better displays, and longer battery life are no longer optional — they are essential. To support this evolution, display components must be smaller, more efficient, and capable of delivering high-quality visuals in a very limited space. Osram has taken a significant step in this direction by unveiling a new RGGB LED designed specifically for compact smart glasses and micro-display systems.
Smart glasses place strict demands on display technology. The light source must deliver vivid colors, stable performance, and high efficiency, all while fitting into an extremely compact form factor. Traditional LED solutions often struggle to balance brightness, color quality, and thermal management at this scale.
The RGGB LED architecture addresses these challenges directly. By using red, green, green, and blue chips in a single package, this design improves color balance and brightness efficiency. The extra green channel enhances luminance perception, which is especially important for wearable displays used in both indoor and outdoor environments.
Osram’s new RGGB LED is engineered for applications where space is limited. With a footprint of just 2.7 × 3.05 mm² and minimal chip-to-chip gaps, it enables more compact optical engines and simpler system layouts. This makes it well suited for LCoS and DMD projector systems used in smart glasses, pico projection, and machine vision.
Despite its small size, the RGGB LED integrates four individually addressable chips. This is a key requirement for micro-display technologies that rely on precise light control to generate sharp, uniform images.
Energy efficiency is critical for wearable devices. A power-hungry display quickly limits battery life and increases heat generation. Osram’s RGGB LED is designed to operate efficiently while maintaining excellent color stability across temperature changes.
Typical dominant wavelengths are:
In terms of output, the LED delivers strong brightness levels across all channels, supporting clear visibility even in challenging outdoor lighting conditions. Reduced heat generation also allows manufacturers to design slimmer and lighter smart glasses without adding complex cooling systems.
For end users, display quality directly affects comfort and immersion. The RGGB LED design helps produce more natural skin tones, vivid textures, and realistic virtual objects. This improves the overall augmented reality experience and helps bridge the gap between digital content and the real world.
For manufacturers, this technology offers greater design freedom. Smaller optical engines, longer battery life, and consistent color performance make it easier to create smart glasses that meet both technical and lifestyle expectations.
By unveiling this compact RGGB LED, Osram reinforces its commitment to advancing micro-display light sources for next-generation wearable devices. The combination of compact size, high efficiency, and strong color performance makes this solution a practical choice for smart glasses that aim to be truly wearable, not just functional.
As the smart glasses market continues to grow, RGGB LED technology is set to play an important role in shaping displays that are lighter, more immersive, and ready for everyday use.
