The viewing area defines the spatial range where users perceive a proper 3D effect without distortion. Autostereoscopic displays have key limitations:
- Near/Far Limits –
- Near Limit: Moving too close causes cross-talk or incomplete view separation due to overlapping perspectives.
- Far Limit: At excessive distances, angular resolution drops, degrading 3D perception.
- Sweet Spot Constraints –
- Fixed-view displays (lenticular/barrier) have a narrow optimal viewing zone; tilting or shifting causes image flipping or blurring.
- Eye-tracking systems expand the sweet spot but still enforce near/far boundaries.
- Optical Trade-offs –
- Wider viewing angles reduce brightness/resolution.
- Larger lens/barrier pitches increase depth range but lower sharpness.
Solutions: Dynamic focus systems, adaptive optics, and multi-view rendering help mitigate these limits.
