Resolution and pixel density are critical in autostereoscopic displays because the screen must render multiple views simultaneously, reducing the effective resolution per eye. Key challenges include:
- View Division – Each eye sees only a fraction of the pixels (e.g., in lenticular or parallax-barrier designs), lowering perceived sharpness.
- Pixel Structure – Subpixel arrangements must align precisely with optical elements to avoid moiré effects or blurring.
- Bandwidth Trade-offs – Higher view counts (for smoother motion parallax) further divide pixel resources, requiring higher native resolutions (e.g., 4K/8K) to compensate.
Solutions include:
- High-PPI Panels – Denser pixels (e.g., OLED, micro-LED) mitigate resolution loss.
- Advanced Rendering – Subpixel interpolation and view-optimized anti-aliasing.
- Hybrid Designs – Time-multiplexing or eye-tracking to dynamically allocate pixels.
