Cylindrical Lens Grating Layout for Crosstalk-Free Stereoscopic Displays

The patent applies local quality by varying the pitch of cylindrical lenses differentially across the display substrate. Specifically, the pitch is set to be smaller in regions closer to the field of view origin and larger in regions farther away, creating a non-uniform pitch distribution that compensates for refraction variations at different viewing angles. This local differentiation eliminates crosstalk and ghosting while maintaining manufacturing feasibility through standardized lens fabrication processes.

The patent applies parameter changes by systematically varying the pitch parameter of cylindrical lenses across different regions of the display substrate. The pitch is calculated based on the distance from the field of view origin, using a defined relationship where pitch increases with distance. This parameter variation strategy reduces crosstalk by compensating for refraction effects, while the pitch calculation formula provides a clear guide for manufacturing precision control.

The patent applies preliminary action by pre-calculating and pre-configuring the pitch of cylindrical lenses during the manufacturing process, rather than adjusting them during operation. The pitch is determined in advance based on the distance from the field of view origin and the desired refraction compensation, embedding the optical correction into the physical structure itself. This preliminary configuration eliminates the need for complex real-time calculations while ensuring optimal display quality across all viewing angles.
