According to an example embodiment of the present disclosure, an electronic device includes a display that is flexible, has at least a portion located at a first side of the electronic device, and is changeable in size to which the display is exposed to the first side, and a controller configured to display content related to a first application in a first area of the display and display content related to a second application in a second area of the display, wherein when an event related to a notification is identified, the controller displays content related to the notification on one area determined from the first area and the second area based on at least one of the content related to the first application and the content related to the second application.

A display panel and a display device are provided. Through setting an area difference between a first sub-display area and a second sub-display area in two directions of the display panel to be less than or equal to a preset value, an area difference between a force-receiving area of the first sub-display area and a force-receiving area of the second sub-display area will be less than or equal to a preset value such that force exerted on the first sub-display area and the second sub-display area is uniform, preventing concentrated force on one side of the display panel from causing the display panel to break.

According to an example embodiment of the present disclosure, an electronic device includes a display that is flexible, has at least a portion located at a first side of the electronic device, and is changeable in size to which the display is exposed to the first side, and a controller configured to display first content in at least a portion of the first side. In response to a first input, the controller displays a first portion of the first content in a first area of the first side and displays a second area distinguished from the first area.

An application interface interaction method. The method includes in response to a first touch operation on a floating notification of a second application displayed on a first interface of a first application, when an electronic device is in an unfolded state, displaying the first interface of the first application and a second interface of the second application in a split-screen manner; and when the electronic device is in a folded state, switching the first interface of the first application to the second interface of the second application, or displaying, in full screen, the second interface of the second application and displaying the first application in a floating point manner or a floating ball manner.

The hinge assembly includes: a rotating assembly and a hovering mechanism. The rotating assembly includes a first rotating part, and the first rotating part comprises a first guide groove extending obliquely around an axial direction of the first rotating part. The hovering mechanism comprises a sliding member and a position limiting member. The sliding member includes a protruding part, the protruding part extends into the first guide groove. The first rotating part drives the sliding member to move along the axial direction of the first rotating part when rotating. One of the position limiting member and the sliding member comprises a first limiting part, the other of the position limiting member and the sliding member comprises a second limiting part cooperated with the first limiting part.

A hinge assembly includes: a fixed supporting piece; a rotating assembly, movably connected with the fixed supporting piece and including a first limiting portion; and a locking mechanism, disposed on the fixed supporting piece and including a limiting piece which includes a second limiting portion matched with the first limiting portion. The fixed supporting piece slides relative to the rotating assembly in a direction perpendicular to an axial direction of the rotating assembly in a rotation process of the rotating assembly, so that the first limiting portion is connected with the second limiting portion or the first limiting portion is separated from the second limiting portion; when the first limiting portion is connected with the second limiting portion, the two limiting portions are matched with each other to limit rotation of the rotating assembly; when separated, limiting of the rotating assembly is released.

A flexible display device is disclosed. The flexible display device includes a flexible substrate, a display structure, a protective structure and an adhesive. The display structure is disposed on the flexible substrate. The protective structure is disposed on the display structure and forms a first accommodating space. The adhesive is disposed in the first accommodating space.

A foldable display device may have housing portions coupled by a hinge. The hinge may have a series of interconnected links. The links may be formed from interdigitated fingers in a friction clutch. The fingers or other portions of the links may be provided with crescent-shaped slots that receive pins. During folding of the device, the pins may slide along the crescent-shaped slots, thereby ensuring that adjacent links rotate relative to each other about a rotation axis that lies outside of the hinge and within a flexible display panel. Links may also be formed from link members with curved mating bearing surfaces that slide relative to each other as adjacent links are rotated relative to each other. A housing rotation synchronization mechanism may be formed using a set of gears that extends between the first and second housing portions.

A display device which includes a display panel and a protection member above the display panel. The protection member may include an adhesive layer above the display panel, a first protection layer above the adhesive layer, and a second protection layer between the first protection layer and the adhesive layer. The first protection layer may have a first thickness and a first modulus, and the second protection layer may have a second thickness less than the first thickness and a second modulus less than the first modulus. The minimum value of the second thickness may be 20 μm, and the maximum value of the second thickness may satisfy Equation (1) below. The display device, which includes the protection member including the second protection layer satisfying Equation (1), may improve impact resistance and maintain reliability.
