The patent application (Publication Number: US20240036328A1) describes a display system that includes a diffuser with a curved surface, a display device emitting light focused on the diffuser, at least one viewing optic, and an eye box. The diffuser diffuses the light emitted by the display device, resulting in a larger cone angle for the light output. The diffused light then passes through the viewing optic to reach the eye box, where a final image is formed for viewing.

The system can have a reflective or transmissive diffuser, with a beamsplitter positioned between the diffuser and the eye box in the reflective configuration. The display device can be a projector with a scanning mirror, focusing optic, or laser emitter, and may include LED or µLED displays, laser projectors, or LED projectors. The intermediate image formed on the diffuser's concave surface can be diffused through a coating or reflected from a reflective surface. The method involves positioning the display device, curved diffuser, and viewing optics to ensure the light output reaches the eye box effectively. Overall, the patent application outlines a display system with innovative features to enhance image quality and viewing experience.
