SYSTEMS, METHODS, AND DEVICES FOR ADHESION OF INTERIOR WAVEGUIDE PILLARS - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240036321 titled 'SYSTEMS, METHODS, AND DEVICES FOR ADHESION OF INTERIOR WAVEGUIDE PILLARS

Simplified Explanation

The abstract describes a near-eye display system that includes a stack of waveguides with pillars in the central portion. The pillars separate and extend between neighboring waveguides, and there are light outcoupling optical elements that outcouple image light towards the viewer's eye. The pillars are bonded to adjacent waveguides, providing thermal stability to resist deformation with temperature changes.

• The near-eye display system includes a stack of waveguides with pillars in the central portion.
• Light outcoupling optical elements are present to outcouple image light towards the viewer's eye.
• The pillars separate and extend between neighboring waveguides.
• Diffractive optical elements may be formed simultaneously with the pillars.
• The pillars are bonded to adjacent waveguides, providing thermal stability to resist deformation with temperature changes.

Potential Applications:

• Augmented reality (AR) headsets
• Virtual reality (VR) headsets
• Heads-up displays (HUDs) in vehicles or aircraft

Problems Solved:

• Provides a high level of thermal stability to the waveguide stack, preventing deformation with temperature changes.
• Enables efficient outcoupling of image light towards the viewer's eye.

Benefits:

• Enhanced image quality and clarity in near-eye display systems.
• Improved thermal stability ensures consistent performance in various temperature conditions.
• Simultaneous formation of diffractive optical elements with pillars simplifies manufacturing processes.

Original Abstract Submitted

in some embodiments, a near-eye, near-eye display system comprises a stack of waveguides having pillars in a central, active portion of the waveguides. the active portion may include light outcoupling optical elements configured to outcouple image light from the waveguides towards the eye of a viewer. the pillars extend between and separate neighboring ones of the waveguides. the light outcoupling optical elements may include diffractive optical elements that are formed simultaneously with the pillars, for example, by imprinting or casting. the pillars are disposed on one or more major surfaces of each of the waveguides. the pillars may define a distance between two adjacent waveguides of the stack of waveguides. the pillars may be bonded to adjacent waveguides may be using one or more of the systems, methods, or devices herein. the bonding provides a high level of thermal stability to the waveguide stack, to resist deformation as temperatures change.
