Display with Lens Integrated Into Cover Layer - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240103280 titled 'Display with Lens Integrated Into Cover Layer

Simplified Explanation

The patent application describes a display system that includes a waveguide with an output coupler, a cover layer with a three-dimensional curvature, and a lens that imparts power to the image light and world light.

• Waveguide with output coupler: The waveguide in the display system has an output coupler that directs image light towards a lens.
• Cover layer with three-dimensional curvature: The cover layer of the display system has an outer surface with a three-dimensional curvature and an inner surface that overlaps the output coupler. This inner surface has a different curvature that forms an additional lens in the cover layer.
• Lens and eye box: The lens in the display system imparts power to both the world light and image light, transmitting them to the eye box for viewing.

Original Abstract Submitted

a display may include a waveguide having an output coupler that couples image light out of the waveguide and towards a lens, which imparts a first power to the image light. a cover layer may have an outer surface with a three-dimensional curvature and an inner surface. a portion of the inner surface overlapping the output coupler may have a different three-dimensional curvature that forms an additional lens in the cover layer that transmits world light to the output coupler. the output coupler may transmit the world light to the lens, which transmits the world and image light to the eye box. the curvature of the portion of the inner surface may impart power to the world light that reverses the first power and/or a power imparted to the world light by the outer surface of the cover layer.
