Abstract: An electronic device with a flexible display subassembly is provided. The display stack may use two layers of adhesives having different elastic properties to improve mechanical impact resistance, with a first adhesive layer made of a viscoelastic material and a second adhesive layer having a low modulus of elasticity. The display stack may also include a hot melt protective sheet (HMPS) covering the display subassembly. The HMPS may be wrapped around the two side edges of a rigid substrate to attach directly to the substrate, thereby aiding in the adhesion of the display stack to the substrate. The display stack may also includes a patterned back protective sheet in which the protective backing layer is removed along the curved portions of the display stack.

Abstract: In some implementations, a process includes forming a layer of a liquid optically clear adhesive (LOCA) on a surface of a first substrate. Additionally, the LOCA can be contacted with a surface of a second substrate. The LOCA can then be exposed to Ultraviolet (UV) radiation. After exposing the LOCA to UV radiation, additional substrates can be coupled to the first substrate, the second substrate, or both to form a display stack. In an implementation, the total energy/unit area for the UV radiation applied to the LOCA can be no greater than 25,000 kJ/cm2.

Abstract: An electronic device includes a stack assembly. The stack assembly is provided with a stack of sub-assemblies such as a display for rendering content, front lighting layered on top of the display for illuminating the display, a capacitive touch sensor layered on top of the front lighting for detecting touch inputs, and a cover glass layered on top of the capacitive touch sensor. Each sub-assembly is adhered to another sub-assembly with a film optically clear adhesive before coupling sub-assemblies with each other, which forms a touch-sensitive front-lit display that is capable of accepting user input and rendering content in low ambient light conditions.
