Abstract: Methods for assembling a narrow border plastic cover include defining a center portion and an edge portion of a plastic cover. A hard coat treatment may be applied to the center portion of the plastic cover to improve anti-glare and anti-scratch properties and mechanical strength while retaining the flexibility of the plastic cover at the edge portion. An optically clear adhesive may be applied to the plastic cover to improve the durability and bond strength of the bond between the narrow border plastic cover and a display. A structural adhesive may be applied to an edge portion of the display to improve the mechanical strength at the edge portion of the plastic cover when bonded to the display. The narrow border plastic cover may be bonded to the display to improve the ability of the display to absorb impacts.
