Abstract
A set of protective layers configured to protect and enhance a display or interface of a device is provided. The layers may include layers of material to strengthen the respective device components to increase durability and reduce damage from impacts. When the layers are impacted by a foreign object, the force may be absorbed by the strengthened component or transferred to other areas of the device, rather than catastrophically damaging the display, encasement or interface of the device. Additionally, the use of functional layers is provided to enhance device performance and user experience. Related assemblies and methods are also provided.
Claims13
A protective layer assembly for a device comprising:
- an outer layer that includes sapphire and has a shape conforming to that of a display of the device or a display cover of the device, wherein the outer layer is a separate layer from a display surface of the device and the display cover of the device, and is attachable to the display surface or the display cover of the device;
- an adhesive layer disposed to couple the outer layer to the display surface of the device or to the display cover of the device;
- a removable protective film affixed to the adhesive layer that is configured to be removable to enable the adhesive layer to couple the outer layer to the display surface of the device or to the display cover of the device;
- and
- a hardened edge strengthening layer permanently attached solely to the outer layer forming a seal of a perimeter of an outer edge of the outer layer as a result of being applied in liquid, paste or spray form directly to the outer edge of the outer layer, the outer edge of the outer layer including side walls connecting a top surface of the outer layer and a bottom surface of the outer layer, wherein the edge strengthening layer is configured to strengthen the outer edge by sealing chips and cracks located in the outer edge.
