Hologram Display Resolution Mixing With Surface Light Source

The patent divides the spatial light modulator into multiple sub-modulators arranged in an array, where each sub-modulator processes a portion of the holographic image. This segmentation allows each individual sub-modulator to use larger pixels while collectively achieving high resolution through the combined output of multiple units.

The patent transitions from a single-plane spatial light modulator to a multi-plane or multi-layer configuration, where holographic images are generated at different depths or layers. This dimensional approach enables high resolution without requiring excessively small pixels in a single plane, as the resolution is distributed across multiple dimensions.

The patent combines multiple spatial light modulators with larger pixels into a unified holographic display system. By merging the outputs of multiple sub-modulators, the system achieves the resolution of a high-pixel-density device while using easier-to-manufacture components with larger pixel sizes.

The overall holographic display function is segmented across multiple independent spatial light modulator units. Each unit can be manufactured separately with larger pixels, and then combined to form a complete high-resolution holographic system, thereby simplifying individual manufacturing steps.

The patent replaces the mechanical/physiological mechanism of binocular disparity (which requires the brain to process two different images from each eye) with a holographic optical field that naturally provides depth information through wavefront modulation. This substitution eliminates the cognitive processing burden that causes fatigue while maintaining stereoscopic effects.

The patent changes the fundamental parameter of depth perception from binocular disparity (difference in horizontal position between eyes) to optical phase and wavefront curvature information provided by holograms. This parameter change allows the human visual system to perceive depth more naturally without the fatigue associated with forcing binocular convergence.

The patent segments the backlight generation function across multiple lower-resolution light-emitting units rather than using a single high-resolution light source. Each unit emits light for a specific region or depth layer, and their combined output creates the high-resolution holographic image, reducing the total energy burden on any single light source.

The patent utilizes the depth dimension to distribute the light emission function across multiple layers or planes. Instead of concentrating all resolution requirements in a single high-power backlight, the system uses multiple lower-power light sources at different depths, each contributing to the overall holographic image formation with reduced individual energy consumption.
