Optical Systems with Reflective Prism Input Couplers - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240272438 titled 'Optical Systems with Reflective Prism Input Couplers
The abstract describes an electronic device with a display module that generates light and an optical system that redirects the light towards an eye box. The system includes an input coupler on a waveguide and a lens that directs the light towards the input coupler. The input coupler has a prism with a reflective surface that reflects the light into the waveguide, which may be curved to provide the light with optical power. The prism expands the field of view of the light, while a birefringent beam displacer expands the effective pupil size of the light. The lens includes lens elements that converge the light at a location between the lens elements and the waveguide, where a switchable panel can be toggled to increase the effective resolution of the light.

Original Abstract Submitted
an electronic device may include a display module that generates light and an optical system that redirects the light towards an eye box. the system may include an input coupler on a waveguide and a lens that directs the light towards the input coupler. the input coupler may include a prism having a reflective surface that reflects the light into the waveguide. the reflective surface may be curved to provide the light with an optical power. the prism may be configured to expand a field of view of the light. a birefringent beam displacer may expand the effective pupil size of the light. the lens may include lens elements that converge the light at a location between the lens elements and the waveguide. a switchable panel may be placed at the location and toggled between first and second orientations to increase the effective resolution of the light.
