Provided is an in-folding type hinge structure having a flexible display panel installed therein in a mobile communication terminal in which a flexible display panel is provided in a pair of panel portions which are foldably connected to each other, in which a stable folding operation can be performed while the panel portions are being folded or unfolded and the panel portions do not rotate over 180 degrees when the panel portions are fully unfolded, whereby damage of the flexible display panel provided on the surfaces of the panel portions can be prevented.

A foldable display device includes a first casing and a second casing. The first casing is rotatable about a first rotation center, and the second casing is rotatable about a second rotation center. Coordinates of an orthographic projection of the first rotation center on an xoy coordinate plane are (x1, y1), and coordinates of an orthographic projection of the second rotation center on the xoy coordinate plane are (−x1, y1). A predetermined value is defined by a sum of coordinate values x1 and y1, the coordinate value x1 is greater than zero, and the coordinate value y1 is greater than −0.3 millimeter (mm) and less than or equal to one mm.

A cover assembly for providing a moisture resistant installation of a receptacle or similar electrical component within a floor box and flush with a newly poured concrete floor surface. The cover assembly includes a floor box, a leveling ring, a mounting plate, and a cover plate with a flip-lid hinged to the cover plate. Sealing means are provided integral with the cover plate for sealing against the floor surface and for sealing the flip-lid to the cover plate to provide a moisture resistant installation of the receptacle. The sealing means includes a lid gasket integral with the flip-lid and a plate gasket integral with the cover plate.

Disclosed is an electronic device including a first housing, a second housing, a display disposed on the first housing and the second housing, a first hinge plate coupled to the first housing, a second hinge plate coupled to the second housing, and at least one hinge structure coupled to the first hinge plate and the second hinge plate, wherein the at least one hinge structure comprises a center bracket, a first hinge bracket coupled to the center bracket and configured to rotate in a first direction, a second hinge bracket connected to the center bracket and configured to rotate in a second direction, and at least one hole formed in the center bracket.

A linear actuator system comprising a linear actuator and at least one box with an openable cover. The box comprises a horizontal hinge pin in each side as well as a track in each side, which the respective hinge pins reach into, and where the track on a first run is horizontal and led out to a free edge such that the cover can be placed on the box in a horizontal movement and that the track has a second run in continuation of the first run, and where the second run has a sloping course, which extends down towards the bottom of the box such that the respective hinge pins when the cover is closed are led into the second sloping course of the track. The cover can thus be removed from the box, in case this would be desired, alternatively the cover can remain on the box and be opened by rotating around the horizontal hinge pins. Due to the design of the tracks, which the hinge pins reach into, the cover can be placed on and removed from the box in a horizontal position. By the sloping course of the track the cover will retract itself to its position when it with the hinge pins is slid into the tracks.

Methods and devices for selectively presenting a user interface in a dual screen device. More particularly, the method includes providing a gallery for the dual screen device. The gallery can present one or more images in a user interface. The gallery user interface can adapt to changes in the device configuration. Further, the gallery can display images or videos in the various configurations.

An electronic device is provided. The electronic device includes a first housing structure including a conductive first side member, a second housing structure including a conductive second side member, a hinge structure rotatably connecting the first housing structure and the second housing structure, and a printed circuit board. The first side member or the second side member may include a first side face, a second side face, a third side face, a fourth side face, a first slit formed in the fourth side face, and a second slit formed in any one of the first side face, the second side face, and the third side face. At least a part of the second side face or the third side face between the first slit and the second slit may be made of a conductive material and electrically connected to the printed circuit board as a radiating conductor.

A portable electronic device is provided. The portable electronic device includes a first housing including a first surface and a second surface a second housing including a third surface and a fourth surface, and a hinge. The hinge includes a hinge shaft, a sliding device including a portion configured to slide to an inside or an outside of the second housing to be introduced, or slide from the inside or the outside of the second housing in a specific direction to be extracted in correspondence to a hinge operation of the second housing, and a multi-bar disposed between the first surface and the fourth surface and including multi-bar units to be spread or bent in correspondence to a hinge operation of the second housing.

An electronic device includes: a panel; and a main body to which the panel is reversibly attached, the main body includes: first and second wiring extraction portions as defined herein; wiring connection terminals that are provided as defined herein; a first wiring area as defined herein; a second wiring area as defined herein; and a wire that extends from one of the first and second wiring extraction portions to one of the wiring connection terminals so as to be electrically connected to the panel, and the wire is arranged to extend from the first wiring extraction portion to the one of the wiring connection terminals via the first wiring area, or is arranged to extend from the second wiring extraction portion to the one of the wiring connection terminals via the first and second wiring areas.

The present disclosure provides a folding display device including a flexible display panel; a first case positioned at a periphery of the display panel; a mid-frame positioned adjacent to the display panel and extending co-planar with the display panel; a plurality of holes extending through the mid-frame at a central region of the mid-frame; a second case positioned adjacent to the mid-frame extending co-planar with the mid-frame; and a third case positioned adjacent to the second case and configured to support the second case. The second case has a hinge part overlapping the plurality of holes in the mid-frame. The holes in the mid-frame and a connecting member holding the holes together in the mid-frame provides elasticity, expandability, and pliability to the folding display device. The connecting member also provides durability so that the folded portion endures the numerous folding and unfolding activities by a user of the display device.
