Dispensable adhesive composition for augmented reality waveguide

A display, comprising:

• a waveguide, the waveguide comprising a substrate with a first surface and a second surface, at least one grating being disposed over the first surface or the second surface;
• a first lens material disposed over the first surface of the substrate;
• a first gap defined by a lower surface of the first lens material and the first surface of the substrate;
• a second lens material disposed over the second surface of the substrate;
• a second gap defined by an upper surface of the second lens material and the second surface of the substrate;
• and
• a first adhesive composition and a second adhesive composition disposed between the first lens material and the first surface of the substrate.

A method for forming a display, comprising:

• depositing an adhesive composition over a first surface of a substrate of a waveguide, wherein the adhesive composition comprises at least a spacer;
• coupling a first lens material to the adhesive composition on the first surface of the substrate, wherein a first gap is formed between the first lens material and the first surface of the substrate;
• depositing a second adhesive composition over a second surface of the substrate of the waveguide;
• and
• coupling a second lens material to the adhesive composition on the second surface of the substrate, wherein a second gap is formed between the second lens material and the second surface of the substrate.
