Eyewear display having offset bonding
Abstract:
Eyewear including a multi-layered display having an adhesive bonding the layers together at an offset distance inward from an outer edge of the layers. The display has an image display layer, such as an optical waveguide in one example, and a pair of layers encompassing the image display layer and which may comprise optically transparent substrates, such as glass. A respective adhesive is positioned the offset distance inward from the outer edge of the display layer between the image display layer and each of the pair of layers to reduce stress in the display. Each of the adhesives may be a continuous bead such that there is no adhesive between the pair of layers and the image display layer at the outer edges. In one example, the offset distance may be at least double the thickness of the image display layer to reduce stress in the image display layer.
