A wearable electronic device according to various embodiments of the disclosure includes: a housing including a first housing part in which a processor is received and a second housing part in which a display is received, and a hinge connecting the first housing part and the second housing part and having a hole provided in an area in communication with an outside of the wearable electronic device. At least part of heat generated from the processor is radiated to the outside through the hinge having the hole formed therein.

Embodiments of this application disclose a housing structure and a terminal device. The housing structure includes a bottom shell and a lifting shell. A first end of the bottom shell is connected to a first end of the lifting shell, a second end of the bottom shell and a second end of the lifting shell are spaced by a first distance, and space between the bottom shell and the lifting shell forms a heat dissipation channel. A heat dissipation panel is disposed on the bottom shell, a first surface of the heat dissipation panel is in contact with a heat emitting component, and a second surface of the heat dissipation panel is located in the heat dissipation channel. Therefore, the housing structure provided in the embodiments of this application can better dissipate heat for the heat emitting component in the bottom shell.

A display assembly with divided interior space includes a first and second electronic display subassembly attached to a structural framework, where each of the subassemblies include an electronic display layer located behind a cover, an illumination device for providing illumination to the electronic display layer when powered, and a passageway for circulating gas. A common passageway for the circulating gas is located between the subassemblies and is in fluid communication with the passageways. A central septum extends within the common passageway between the subassemblies to divide the common passageway into a first portion and a second portion.

Display devices, methods for fabricating display devices, and display systems are provided. For example, a display device comprises a display panel, a display cover bonded to a perimeter of the display panel with a perimeter seal, and an optically clear fluid disposed in a gap between the display panel and the display cover. The optically clear fluid has an index of refraction that is substantially matched to an index of refraction of the display cover. The optically clear fluid may comprise oil, alcohol, water, or a liquid gel, for example.
