  • Patent number: 10320959
    Abstract: Transparent structures for portions of electronic device housings are disclosed. The transparent structures are formed from multiple layers of transparent (optically clear) materials. The multiple layers can include at least an outer glass layer and one or more other transparent layers that can be either glass or polymer layers. The multiple layers can be bonded together with one or more lamination layers. Accordingly, multi-layer transparent structures that are formed from multiple layers bonded together are able to be not only thin but also sufficiently strong and resistant to damage. The multi-layer transparent structures are well suited for use in consumer products, such as consumer electronic devices (e.g., portable electronic devices).
