What it is
A display approach that forms the image on the retina rather than on an intermediate panel.
How it works
A MEMS mirror steers modulated laser light through the pupil, painting the image line by line.
Why it matters
Retinal projection can create images that stay in focus regardless of the viewer's refractive error.
Advantages
- Large depth of focus
- Potential accessibility uses
- Very small optics
Current limitations
- Eyebox alignment
- Laser safety certification
- Low production volumes
Commercial readiness
Specialist and assistive products only.
