  • Publication number: 20240168296
    Abstract: An electronic device may include a first bias lens that transmits world light to an output coupler on a waveguide. The output coupler may transmit the world light while coupling image light out of the waveguide. A second bias lens may transmit the world light and the image light to an eye box. A tint layer may transmit the world light towards the output coupler. The tint layer may be planar and layered onto a planar surface of the first bias lens or another lens, may be separated from the first bias lens by an air gap, may be non-parallel relative to the waveguide, and/or may be curved and separated from the first bias lens and the waveguide by air gaps. When planar, the tint layer may be provided with spacers between substrates or between the tint layer and the waveguide to maximize parallelism.

  • Publication number: 20230382085
    Abstract: An electronic device may have optical components that each have first and second transparent layers such as first and second glass layers. The glass layers may have outer surfaces that face away from each other and inner surfaces that face towards each other. A polymer layer is formed between the inner surfaces of the glass layers. Along the periphery of each optical component, a hermetic seal is formed to protect the polymer material of the polymer layer. The seal may have a moisture barrier layer that is attached to the first and second glass layers. The moisture barrier layer may be supported by an elastomeric buffer member. The moisture barrier layer may be formed from metal film or a polymer layer or other substrate that is coated with a moisture-impermeable coating. The moisture-impermeable coating may be formed from one or more thin-film metal layers and/or one more thin-film dielectric layers.
