Abstract
A foldable screen assembly includes a planar electronic display that has substantially parallel and opposed first and second surfaces. A planar lens assembly has a third surface that is positioned adjacent to the first surface. A first optically clear adhesive extends between the first surface of the electronic display and the third surface of the planar lens assembly. A first area of the first optically clear adhesive is selectively cured to have a first modulus and a second area of the first optically clear adhesive is selectively cured to have a second modulus. The selectively cured first and second areas allow the foldable screen assembly to bend.

A foldable screen assembly comprising:
- a planar electronic display having substantially parallel and opposed first and second surfaces;
- a planar lens assembly having a third surface that is positioned adjacent to the first surface, the planar lens assembly comprising a bendable lens;
- a first optically clear adhesive extending between the first surface of the electronic display and the third surface of the planar lens assembly, the first optically clear adhesive being an ultra violet (UV) cured adhesive, wherein a first area of the first optically clear adhesive is selectively cured using a UV light and a UV mask to provide uncured areas having a first modulus that allows the uncured areas to be flexible and a second area of the first optically clear adhesive is selectively cured to provide cured areas having a second modulus that allows the cured areas to be rigid relative to the uncured areas, the selectively cured first and second areas allowing the foldable screen assembly to bend at the first area;
- a second optically clear adhesive attached to the second surface of the electronic display, the second optically clear adhesive being a low modulus low density adhesive that cures without UV light;
- a support sheet attached to the second optically clear adhesive such that the support sheet is juxtaposed to the second surface and the second optically clear adhesive is located between the electronic display and the support sheet;
- a bendable touch sensor;
- a polarizer that is an optical filter;
- and
- a third optically clear adhesive located between the polarizer and the bendable touch sensor, the third optically clear adhesive being a reworkable adhesive.
