A rollable display apparatus includes a flexible panel including a main panel with a display and a dummy panel with a wire connected to the display, a housing to accommodate the flexible panel, a rotatable rolling drum in the housing and coupled to a first end of the flexible panel, a supporting base moveable into and out of the housing and coupled to a second end of the flexible panel, and a printed circuit board connected to the second end of the flexible panel, the printed circuit board being on the supporting base.

Some embodiments described herein relate to head-mounted displays having an optical assembly and a support structure. The optical assembly can include the display, lenses, sensors, electronics and similar components. In this way, fragile and/or expensive components can be concentrated in the optical assembly. The support structure can include a faceplate and straps configured to hold the head-mounted display to the user's head. The optical assembly can be removeably coupled to the support structure. Support structures can be interchangeable with optical assemblies such that one support structure can be configured to be removeably coupled to all, most, or several optical assemblies.

An electronic device may have a hinge that allows the device to be flexed about a bend axis. A display may span the bend axis. To facilitate bending about the bend axis without damage, the display may include a display cover layer with a flexible portion. The flexible portion of the display cover layer may be interposed between first and second rigid portions of the display cover layer. The display cover layer may also include a layer with self-healing properties. The layer of self-healing material may be formed across the entire display cover layer or may be formed only in the flexible region of the display cover layer. The display cover layer may include a layer of elastomer in the flexible region of the display cover layer for increased flexibility. Self-healing may be initiated or expedited by externally applied heat, light, electric current, or other type of external stimulus.

A display device may include a display panel, a first back cover disposed on a rear surface of the display panel, at least one flexible film which is electrically connected to one end of the display panel and is bent toward a rear surface of the first back cover or a front surface of the display panel, and a printed circuit board which is electrically connected to the at least one flexible film and disposed on the rear surface of the first back cover or the at least one flexible film. The printed circuit board overlaps one end of the display panel. Accordingly, one end of the display panel in which the pad area which is vulnerable to the stress is disposed and the printed circuit board are maintained to be flat, to minimize the damage of the display device.

A solar powered vehicle topper unit and systems and methods for the same are provided. A solar energy harvesting device is electrically connected to an electronic display within a housing. The solar energy harvesting device is located above the housing. The solar energy harvesting device has a first footprint, and the housing has a second footprint which is smaller than the first footprint.

A display device, a bent spacer module and an assembling method thereof are provided. The display device includes: a protective cover plate; a display module, including a display surface facing the protective cover plate and a back surface away from the protective cover plate; a chip-on-film, at least part of the chip-on-film being located on the back surface and being in binding connection with an edge of the display module; a driving chip, which is located on a side, facing the display module, of the chip-on-film on the back surface, and is in binding connection with the chip-on-film; and a bent space, which is located between the driving chip and the back surface, a thickness of a part of the bent spacer contacting the driving chip being greater than that of the remaining part of the bent spacer.

An electronic device comprises a first case, a resin plate, and a display. The first case has a first surface and a second surface. The resin plate is located inside the first case. The display is located on a side facing the first surface of the first case.

Field serviceable display assemblies are provided. Multiple side assemblies are mounted to a structural framework in a moveable manner, each including a channel located between a transparent layer and an electronic display, which is located behind the transparent layer. A fixed structure is positioned within a cavity located within the structural framework and between the side assemblies. The fixed structure remains stationary when the side assemblies are moved between a closed position where the cavity is enclosed, and an opened position where the fixed structure is exposed to facilitate direct access to electronic components located thereon.

A display module includes a display panel, a first backplate, a super clear foam (SCF) assembly and a reinforcement plate. The first backplate is disposed on a side of a display panel opposite to a light emission surface. The SCF assembly and the reinforcement plate are disposed on a side of the first backplate opposite to the display panel. A receiving slot is defined in a side of the SCF assembly opposite to display panel. At least one part of the reinforcement plate is received in the receiving slot, and a driver chip is located on a side of the reinforcement plate opposite to the display panel.

A display device includes a display panel to display an image; a heat radiating member at a side portion of the display panel and including a first adhesive layer, a second adhesive layer, and a heat radiating layer between the first adhesive layer and the second adhesive layer; and a heat generating member overlapping the display panel and the heat radiating member when viewed in a plan view, and the heat radiating member includes a first area overlapping the heat generating member and a second area adjacent to the first area when viewed in a plan view, the first adhesive layer and the second adhesive layer are connected to each other through a plurality of through holes defined through the heat radiating layer, and the plurality of through holes includes a through hole in the second area.
