Solution Overview

Problem

Traditional electronic devices often have separate display and input components that are prone to scratching and provide an inferior tactile feel or visual appearance, and their enclosures are not seamlessly integrated.

Innovation Solution

An electronic device featuring a glass housing member with a continuous exterior surface that integrates both display and input areas, formed from a single piece of optically transmissive material such as glass, which is molded to include planar and curved portions, and supported by a structure that allows for flexible positioning and enhanced durability.
