Abstract: A screen protector comprises a glass-based substrate and an adhesive. The glass-based substrate comprises a first major surface, a second major surface, a thickness, and an edge. The first major surface comprises a first planar portion and a peripheral portion extending outwardly from the first planar portion. The second major surface comprises a second planar portion opposite the first planar portion and is parallel to the first planar portion. The edge comprises an outer peripheral surface that intersects the peripheral portion of the first major surface. The adhesive comprises a first major surface, a second major surface, a thickness, and an edge. The first major surface of the adhesive is adhered to the second major surface of the glass-based substrate.

Abstract: A screen protector is described herein that is configured to be releasably attached to an optical coating on a glass-containing display of an electronic device. The protector comprises: a glass-containing substrate comprising an outer and inner primary surface; an antireflective (AR) coating on the outer primary surface; and an interlayer on the inner primary surface for releasable attachment to the optical coating on the display. The interlayer comprises an adhesive, a physical thickness from about 10 μm to 500 μm, and one or more refractive indices from ˜1.2 to 1.6. Further, an average photopic reflectance of the screen protector can be less than 2% for all incident angles from 0° to 30°. The interlayer can comprise optically clear adhesive (OCA), polymer-containing layer, and releasable adhesive layers. An anti-splinter (AS) film can be between the interlayer and the substrate. The interlayer and/or AS film may be a cyclo olefin, cellulose triacetate or polyurethane.
