Head-Mounted Display Beam Offset for High Resolution

The patent divides the field of view into multiple segments that are displayed sequentially rather than simultaneously. The spatial light modulator displays different segments at different time points, and the human visual system integrates these segments into a complete image. This segmentation allows high-resolution display of a large field of view without requiring a correspondingly large number of physical pixels on the spatial light modulator, thereby maintaining device compactness.

The patent segments the holographic content and displays different segments sequentially using the same optical path. This approach avoids the need for complex optical systems with multiple spatial light modulators or complex beam splitting arrangements that would be required to display all segments simultaneously. The sequential display approach maintains simpler optical setup while achieving high effective resolution.

The patent divides the expanded field of view into multiple segments that are displayed sequentially rather than simultaneously. Each segment can be optimized for its specific angular range, and aberrations can be corrected on a per-segment basis during the hologram calculation phase. This approach simplifies the optical design compared to conventional tiling methods that require all segments to be visible simultaneously, as the sequential display allows the same optical path to be optimized for one segment at a time.
