Abstract
This publication describes improved foldable display structures that incorporate a cover glass carrier film (“carrier film”) to separate a flexible transparent layer from lower layers of the foldable display structure. A foldable display structure may include, for example, a transparent layer that is formed of a layer of ultra-foldable glass (UFG) that may include a recess filled with an optical-index matching polymer (OIMP) or segments of ultra-thin glass (UTG) joined by a section of OIMP. Conventionally, the transparent layer may be joined to lower layers of the foldable display structure, such as a panel layer, with an optically-clear adhesive (OCA). However, introducing a carrier film, which may be formed from a polyimide film inserted between the panel layer and the transparent layer, provides benefits in terms of flexibility, durability, reliability, touch rigidity, and other considerations. The introduction of the carrier layer, by reducing spring-back force, may avoid a user having to apply significant force to close the foldable display structure, thus potentially avoiding damage to the foldable display structure while providing a better user experience.
