The present disclosure relates to a flexible display device including a first body; a second body configured to be relatively movable with respect to the first body; a flexible display disposed on a front surface of the first body and a rear surface of the second body, respectively, and configured to vary in size of areas that are exposed to the front surface of the first body and to the rear surface of the second body as the first body and the second body are relatively moved; and a rotating bending bar disposed in at least one of the first body and the second body, and rotated while the first body and the second body are moved to couple the first body and the second body.

A portable terminal is provided for operation in a first mode in which information is provided on a first curved surface area or a second mode in which information is provided on a second curved surface area, and controlling the display to provide, in response to an occurrence of an event while in the first mode, information related to the event on the first curved surface area, and provide, in response to the occurrence of the event while in the second mode, information related to the event on the second curved surface area.

A display device includes a display module including a bending area at which the display module is bent, and a non-bending area which extends from the bending area; a driving control module connected to the bending area of the display module; and a protective cover removably attachable to the display module, the protective cover including a cover portion and a support protrusion which protrudes from the cover portion. The display module bent at the bending area thereof disposes the driving control module facing a rear surface of the display module, and the protective cover attached to the display module bent at the bending area thereof disposes each of: the cover portion of the protective cover corresponding to the bending area of the display module and to the driving control module facing the rear surface of the display module, and the support protrusion corresponding to the driving control module.

Electronic devices may be provided that contain flexible displays that are bent to form displays on multiple surfaces of the devices. Bent flexible displays may be bent to form front side displays and edge displays. Edge displays may be separated from front side displays or from other edge displays using patterned housing members, printed or painted masks, or by selectively activating and inactivating display pixels associated with the flexible display. Edge displays may alternately function as virtual buttons, virtual switches, or informational displays that are supplemental to front side displays. Virtual buttons may include transparent button members, lenses, haptic feedback components, audio feedback components, or other components for providing feedback to a user when virtual buttons are activated.

The present disclosure relates to a flexible display device case that is mounted to a flexible display device including a first body and a second body configured to be movable relative to the first body, and including a first member mounted to the first body to surround a side surface portion of the first body, and a second member mounted to the second body to surround a side surface portion of the second body, wherein an area overlapped by the first member and the second member changes as the first body and the second body move relative to each other.

The invention relates to: a light-emitting device which includes a first flexible substrate having a first electrode, a light-emitting layer over the first electrode, and a second electrode with a projecting portion over the light-emitting layer and a second flexible substrate having a semiconductor circuit and a third electrode electrically connected to the semiconductor circuit, in which the projecting portion of the second electrode and the third electrode are electrically connected to each other; a method for manufacturing the light-emitting device; and a cellular phone which includes a housing incorporating the light-emitting device and having a longitudinal direction and a lateral direction, in which the light-emitting device is disposed on a horn side and in an upper portion in the longitudinal direction of the housing.

An electronic device is provided, including a housing, a screen, a deformation drive part, and a camera. The screen and the housing form an inner cavity in which the camera and the deformation drive part are disposed. The deformation drive part drives a second area located at an edge of the screen to switch between a flattened state and a curved state through deformation. When the second area is in the flattened state, the second area is a flat second plane area, and the second plane area is located in the same plane as a first plane area of a first area of the screen. A light-transmitting area is disposed in the second area. In the case that the second area is in the flattened state, ambient light passing through the light-transmitting area is projected onto the camera.

A display panel and display device are provided. The display panel includes a cover plate, padding part and display assembly. The cover plate has a bending part. The padding part is provided at a bending inner side of the bending part. An extension direction of the padding part is consistent with that of the bending part, and a sectional shape of the padding part perpendicular to the extension direction is provided as a structure gradually thickening from both side edges to a centre portion. The padding part has a first curved surface being a cylindrical surface, and the first curved surface is a surface of the padding part away from the cover plate, is concave toward the bending part, and smoothly transits to the cover plate. The display assembly is provided at a side of the first curved surface away from the cover plate.
