A MEMS-based collimated light scanner inside the Bosch Smartglasses Light Drive module scans a holographic element (HOE) that is embedded in the lens of the smartglasses. This HOE redirects the light beam onto the human retina surface, directly painting a picture that is always in focus. The technology enables hands-free, secure viewing of practically any data from a connected mobile device, such as a paired smartphone, overlaid in a comfortable viewing position. The projected high-resolution image is crisp, bright, private, and clearly visible even in direct sunlight thanks to its adaptive brightness.
The Bosch Light Drive technology is compatible with curved and corrective lenses, making this new tech appealing and available to users who already wear prescription glasses. Older competitor display technologies are hindered by a haze or rainbow glare called stray light that is visible when the system is switched off. It provides pleasing all-day optical transparency with minimal stray light sensitivity, meaning the view is always crystal clear, and that distracting internal reflections are a thing of the past.
