Crosstalk occurs when light from one viewpoint (intended for one eye) leaks into another viewpoint (meant for the other eye), causing ghosting or double images. In autostereoscopic displays (which don’t require glasses), crosstalk arises due to imperfect optical separation between views, often caused by:
- Lenticular Lens/Barrier Misalignment – Imperfections in the lens sheet or parallax barrier.
- Diffusion/Scattering – Light spreading beyond its intended direction.
- Pixel Addressing Errors – Mismatches in view-dependent subpixel rendering.
High crosstalk reduces 3D image quality and viewer comfort. Mitigation methods include optimized optical design, precise calibration, and advanced rendering algorithms.
