An electronic device may include: a bracket including a mounting portion; a printed circuit board (PCB) overlapping with the bracket; a heat generating component on a surface of the PCB, the surface of the PCB facing the bracket; a battery spaced apart from the heat generating component, the battery being in the bracket; and a vapor chamber on the mounting portion of the bracket, wherein the vapor chamber includes: a first portion above the heat generating component, a second portion between the mounting portion and the battery, and a third portion extending from the first portion of the vapor chamber to the second portion of the vapor chamber.

A window includes a substrate including a folding portion foldable with respect to a folding axis extending in a first direction. A plurality of groove patterns are defined in the folding portion. The folding portion includes a center portion and an outer portion, and the plurality of groove patterns include a first groove pattern disposed in the center portion and a second groove pattern disposed in the outer portion. The first groove pattern includes a first upper groove pattern and a first lower groove pattern, and the second groove pattern includes a second upper groove pattern and a second lower groove pattern. The first upper groove pattern and the first lower groove pattern partially overlap in the second direction, and the second upper groove pattern and the second lower groove pattern do not overlap in the second direction.

An electronic device hinge includes a first body, a second body, and a link. The link is rotatable relative to the first body around a first pivot point and rotatable relative to the second body around a second pivot point. The first pivot point has a first rotational resistance and the second pivot point has a second rotational resistance that is different from the first rotational resistance. The hinge further includes a third body that is selectively positionable relative to the first body in a first configuration. The third body limits a first rotational range of motion around the first pivot point when positioned in the first configuration.

An electronic apparatus includes a display module including a folding portion folded about a folding axis extending along a first direction and first and second non-folding portions spaced apart from each other with the folding portion interposed therebetween. A support plate is disposed on a lower side of the display module and includes openings overlapping the folding portion. An adhesive layer is disposed on an upper side of the support plate and overlaps the folding portion, the first non-folding portion, and the second non-folding portion, and a cover attached on a lower side of the support plate, and overlapping at least the folding portion. A through portion passes through the cover along a through direction, and has a depth along a third direction which is perpendicular to first and second directions. The through portion is connected to at least one of the openings.

A display device includes a display module including a folding display portion, a first non-folding display portion, and a second non-folding display portion, and a support plate disposed below the display module and including a folding support portion, a first non-folding support portion, and a second non-folding support portion, wherein the support plate includes a matrix portion, first fibers dispersed in the matrix portion, and second fibers dispersed in the matrix portion, the first fibers each include a plurality of first sub-fibers corresponding to the folding support portion and spaced apart at a first interval, and a plurality of second sub-fibers corresponding to the first non-folding support portion and the second non-folding support portion and spaced apart at a second interval which is smaller than the first interval.

A hinge assembly is provided. The first swing arm includes a first hinge connecting part and a first rotating part. The first swing arm is rotatable relative to the base around a first axis between the first hinge connecting part and the first rotating part. The second swing arm includes a second hinge connecting part and a second rotating part. The second swing arm is rotatable relative to the base around a second axis between the second hinge connecting part and the second rotating part. The second axis is parallel to the first axis. The slider includes a first fastening part, a second fastening part, and an extension part. The extension part is located in the guide groove. The first fastening part is movably connected to the first hinge connecting part. The second fastening part is movably connected to the second hinge connecting part.

A display device includes a folding region, and a non-folding region which is adjacent to the folding region along a first direction, a display module which displays an image, a window on the display module, a lower support plate facing the window with the display module therebetween, the lower support plate including a metal material, and an upper support plate between the display module and the lower support plate. The upper support plate includes a support layer including glass fiber and a polymer material, a first surface including a first concave-convex pattern, and a second surface opposite to the first surface, closer to the display module than the first surface and including a second concave-convex pattern and a metal layer directly on the first surface of the support layer, in the non-folding region.
