Optical Systems Having Compact Display Modules - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240103272 titled 'Optical Systems Having Compact Display Modules
Simplified Explanation
The patent application describes a display system that includes illumination optics, a spatial modulator, and a waveguide to direct image light towards an eye box. The illumination optics consist of light sources, an x-plate, and at least one Fresnel lens to minimize the size of the optics while maintaining optical performance. The spatial light modulator includes a reflective display panel and a powered prism with a reflective coating on a curved surface to optimize f-number and minimize volume. Collimating optics include a diffractive optical element to compensate for thermal effects and chromatic dispersion.
