News Summary

• Unlike conventional optics that manipulate light using mirrors for reflection or lenses for refraction, these holographic micro-optical elements rely on lasers and diffraction.
• These elements are so small that they can be applied to foils or a single piece of flat glass.
• The embedded microstructures are engineered to interact exclusively with specific laser wavelengths and incident angles emitted by a Picture Generation Unit (PGU) Ambient sunlight and external light pass through unhindered, preventing display washout.
