▎ 摘　　要

NOVELTY - The computing device has a see-through display system including an optical component (106) through which a surrounding environment is viewable. An electrical component is arranged on a user-facing side of the optical component. A graphene-based layer is arranged on the optical component. The graphene-based layer comprises a greater thickness of a graphene-based material on a portion closer to the electrical component and a lesser thickness of the graphene-based material on a portion farther from the electrical component. USE - Computing device. ADVANTAGE - The head-mounted display device can utilize augmented reality technologies to enable simultaneous viewing of virtual display imagery and a real world background. The thermal expansion and/or warpage of the see-through optical component over time can be prevented. The heat can be dissipated more quickly and thus lower device temperatures, and thus can help to reduce any risk of warpage. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram illustrating a head-mounted display device.
