Abstract
The present invention may relate to provision of a mechanism to join together the various substrate layers of a flexible display with optically clear adhesives that permit improved flexibility of the substrate layer stack and may also optically guide images to locations on a display surface that are not aligned with the display layer of a substrate layer stack. Embodiments of the present invention may provide for an improved user interface which may include enhanced flexibility and enhanced optical characteristics.
Claims20
A method comprising:
- depositing a layer of optically clear adhesive on a first substrate;
- and
- laminating a second substrate to the optically clear adhesive opposite the first substrate;
- wherein a first region of the optically clear adhesive comprises a first elastic modulus,
- wherein a second region of the optically clear adhesive, exclusive of the first region, comprises a second elastic modulus, and
- wherein the first elastic modulus is different from the second elastic modulus.
