A foldable display apparatus may include: a housing frame including a first frame and a second frame; a hinge assembly coupled to the first frame and the second frame to implement a folding and unfolding movement of the first frame and the second frame; and a display panel disposed on the first frame and the second frame. The hinge assembly may include: a plurality of hinge arms each coupled to one of the first frame and the second frame; a hinge housing disposed below the plurality of hinge arms and accommodating the plurality of hinge arms; and an arm cover disposed above the plurality of hinge arms and fastened with the hinge housing, the arm cover including a plurality of recessed guide units respectively corresponding to the plurality of hinge arms.

A flexible display includes a foldable display coupled to a foldable substrate. The foldable substrate is preformed to maintain a curvilinear three-dimensional shape when in a neutral, force-free state. The curvilinear three-dimensional shape can simulate one or more contours of an electronic device housing to which the flexible display is attached, thereby reducing or minimizing stress loads on the flexible display as the electronic device housing transitions between an axially displaced open position and a closed position.

An electronic device including a hinge module, a first body, a first linking assembly, a second body, a second linking assembly, and a flexible display assembled to the first body and the second body is provided. The hinge module includes a first rotating shaft, a second rotating shaft parallel to the first rotating shaft, a first guiding shaft orthogonal to the first rotating shaft, and a second guiding shaft orthogonal to the second rotating shaft. The first body is slidably assembled to the first guiding shaft, the second body is slidably assembled to the second guiding shaft, the first linking assembly slidably assembled to the first guiding shaft connects the first body, and the second linking assembly slidably assembled to the second guiding shaft connects the second body. A deformation of the flexible display drives the first and second bodies to move close to or away from the hinge module.

Disclosed is a display apparatus including a display panel including a front portion, a bent portion, and a pad portion bent from the bent portion and positioned under the front portion, a first plate disposed between the front portion and the pad portion and disposed under the front portion, and a second plate disposed between the front portion and the pad portion and disposed on a top face of the pad portion, wherein the first plate includes a porous member, wherein the second plate includes a transparent area.

The disclosure relates to an electronic device including a flexible display for screen recording, and a method thereof. The electronic device may include: a memory, a display module including a flexible display, and at least one processor electrically coupled to the memory and the display module. The at least one processor may be configured to: record a screen of the display displayed in an visible area of the display in a reference screen size, based on a screen size of the visible area being changed by extension or contraction of the display during the recording, control the display module to display an object to which a visual effect related to at least one content displayed on the screen is applied, in part of the visible area corresponding to the changed size, and in response to completion of the extension or contraction of the visible area of the display during the recording, control the display module to display an extended or contracted screen in an extended visible area or a contracted visible area.

According to an embodiment of the disclosure, an electronic device comprises a first housing structure; and a second housing structure hingedly connected to the first housing structure along a hinge axis, wherein a first surface of the first housing structure faces a first surface of the second housing structure in a folded configuration of the electronic device, and the first surface of the first housing structure and the first surface of the second housing structure are planar in an unfolded configuration of the electronic device; a first display disposed on the first surface of the first housing structure and the first surface of the second housing structure, and bendable about the hinge axis; and a sliding structure retractably disposed in the first housing structure, configured to protrude to the outside of the first housing structure in a direction substantially co-planar to the first surface of the first housing structure, the sliding structure comprising at least one optical input module facing a direction substantially orthogonal to the first surface.

An example electronic device may include a housing, a flexible display, wherein at least a portion of the flexible display which is positioned in the housing is configured to be exposed to an outside of the housing as the housing slides, a speaker, and a processor operatively connected with the speaker and the flexible display. The processor may be configured to control the speaker to output a first sound at a first volume value while a state of the housing is a normal state, identify a size of a first area of the flexible display exposed to the outside, based on a first slide of the housing to change the state of the housing to an extended state, and control the speaker to output the first sound at a second volume value higher than the first volume value based on a size of the first area while the state of the housing is the extended state.

An electronic device comprises a first structure including a first plate providing a first surface and a second surface and a second structure coupled to surround at least a portion of the first structure and configured to guide the first structure in a direction parallel with the first surface or the second surface. The device also includes a roller mounted on an edge of the second structure and a flexible display including a first area mounted on the first surface and a second area extending from the first area. The device also includes at least one support sheet mounted on the roller and wound around the roller as the roller rotates.
