An electronic device may have a housing with a display. The display may be overlapped by an image transport layer such as a coherent fiber bundle or layer of Anderson localization material. The image transport layer may have an input surface that receives an image from the display and a corresponding output surface to which the image is transported. The input surface and output surface may have different shapes. A wristwatch device may, as an example, have a rectangular or hexagonal input surface and may have an output surface such as a rectangular output surface with rounded corners or a circular output surface. A region of the output surface may have compound curvature. A portion of the image transport layer may protrude laterally over an inactive portion of the display.

A user-worn device includes a band portion and a display portion. The band portion comprises a wire that is configured to create a first magnetic field that follows the curvature of the band portion. The display portion comprises a first electromagnet that is configured to produce a second magnetic field. The display portion orbits around the band portion in a first orbital direction when the first and second magnetic fields interact.

An object includes an electro-optic display device provided with an optically active element, the optical properties thereof can be modified by applying an electric voltage or current between at least one electrode and one corresponding auxiliary electrode, between which the optically active element is disposed. The object further includes a middle part which delimits an opening closed by a crystal including a bottom surface beneath which the electro-optic display device is arranged. The crystal is provided with an opaque frame which is made remotely from the edges of the opening and which covers the contour of the electro-optic display device so as to conceal electrical connection elements. The electro-optic display device defines an active display area which is confined by the opaque frame, such that, when the electro-optic display device is activated and displaying information, a transparent area remains between the opaque frame and the edges of the opening.

Aspects of the technology provide a symbiotic graphical display on a client device such as a smartwatch. The system includes at least one emissive display element and at least one non-emissive display element. The display elements are arrayed in layers or other configurations such that content or other information is concurrently aligned across the respective display surfaces of the different elements. A first set of content is rendered using the non-emissive display element while a second set of content is rendered using the emissive display element. Depending on characteristics or features of a given content item, that item may be rendered by one or both of the display elements. Certain content may be transitioned from the emissive display element to the non-emissive display element according to a time threshold or other criteria.

An apparatus for a wearable device with expandable display strips, the apparatus includes a first layer with a first display panel coupled to a second layer with a second display panel, where the first display panel can extend and retract over a top surface of the second display panel. The apparatus also includes a first gear and rack mechanism coupled to the top surface of the second display panel and a bottom surface of the first display panel, where the first gear and rack mechanism is configured to extend and retrack the second layer with the second display relative to the first layer with the first display. Furthermore, the first layer and the second layer are arranged in a concentric manner.

A proposed device is composed of a smartwatch unit, including at least a display unit of the smartwatch, and a box, including a housing to accommodate the smartwatch. The box has a cover being openable and closeable to cover the display unit, wherein the cover has at least one hole so that a corresponding portion of the display unit is visible to a user when the cover is in closed position, and wherein when the cover is in closed position, the smartwatch unit displays the output of the smartwatch in/on the corresponding portion of the display.

An electronic device including a flexible display is provided. The electronic device includes a first housing, a second housing slidably coupled to a side surface of the first housing, a flexible display including a first area on the first housing and a second area extending from the first area, a gear structure arranged in the first housing, and an installation member rotatably coupled to the first housing and separated from or mounted on at least a part of a human body, wherein the flexible display can be rotated and rolled according to the rotation of the gear structure while the first area is exposed to the outside, such that at least a part of the second area may be exposed to the outside.

A support frame for a bendable display screen includes: a fixed part; a bendable part connected with the fixed part; and an end part arranged at an end of the support frame. The bendable part includes a first bendable part and a second bendable part. The first bendable part includes a plurality of first frame members connected with one another, and the plurality of first frame members have a gap therebetween. The second bendable part is connected with the end part. Both the end part and the fixed part are provided with a limiting member.

An interchangeable smartwatch system includes a smartwatch body and a band including one or more sensors. The smartwatch body is removable from the band, which permits a user to continue to collect data, such as the user's heartrate, when the smartwatch body is removed from the band. The smartwatch body can receive a wireless charge when removed from the band, and then transfer a charge to the band when the smartwatch body is reconnected to the band.

An electronic device includes a first body and a second body which are detachably connected. The first body includes a frame and a fixing apparatus, and the second body includes a main functional unit. The fixing apparatus is connected to the frame and configured to fix the electronic device to an operation body. When the electronic device is fixed to the operation body via the fixing apparatus, the fixing apparatus and the frame form a ring-shaped space. A method for controlling power supply of the electronic device is also provided.
