摘要： A display device includes a display module, a supporting plate disposed under the display module, supporting bars disposed under the display module and arranged in a first direction with the supporting plate, a supporting film disposed between the display module and the supporting plate and between the display module and the supporting bars, a first case accommodating the display module, the supporting plate, the supporting film, and the supporting bars, and a second case coupled to the first case to move in a direction to be close to or to be far away from the first case along the first direction. Opposite sides of the supporting bars are respectively inserted into first guide grooves defined in inner side surfaces of the first case, which face each other in a second direction crossing the first direction, and the supporting bars move along the first guide groove.

摘要： A display device includes a first display area, a second display area, a third display area having a curved shape, and a fourth display area. The display device includes a display panel, an inner cover member, a first outer cover, and a hinge member. The display panel overlaps the first, second, third, and fourth display areas. The inner cover member covers an outer periphery of the display panel overlapping the first, second, and third display areas. The first outer cover member surrounds the inner cover member. The hinge member is disposed on a bottom surface of the display panel to overlap a boundary between the second display area and the fourth display area, and is connected to the first outer cover member. The display panel is folded and unfolded through the hinge member. The inner cover member is drawn in to and out from the first outer cover member.

摘要： A display device may include a first non-folding region, a second non-folding region, and a folding region. The display device may include a display member including a display module, a supporting member supporting the display member, an adhesion member disposed between the display member and the supporting member, and a compensation member attached to one of top and bottom surfaces of the adhesion member and overlapped with the folding region. Thus, it may be possible to provide a display device configured to reduce a stress, which is exerted on a folding region when it is in a folded state, and to prevent the folding region from being deformed to a bent shape when it is in an unfolded state.

摘要： An electronic device includes a first plate, a second plate continuously moving between a first state and a second state with respect to the first plate, a camera module disposed between the first plate and the second plate and including a lens, a flexible display including a planar portion and a bendable portion, and a multi-joint module overlapping the bendable portion of the flexible display and including a plurality of segment members. A position of the camera module and a direction of the lens may be changed in response to a state transition of the electronic device. The plurality of segment members may include at least one opening segment member, and an opening is formed in the opening segment member. The opening segment member may be moved in response to a change in the position of the camera module and a change of the direction of the lens.

摘要： A display apparatus includes a display panel configured to display an image. A first mold is disposed under the display panel and includes a plurality of sidewall portions. A second mold is disposed adjacent to one of the sidewall portions and is coupled to the first mold. At least one flexible circuit board is connected to the display panel and is disposed between the first and second molds. The second mold includes a bottom mold covering one edge area of a bottom surface of the first mold. A cover mold covers the one sidewall portion of the first mold. A first distance between an inner side surface of the cover mold and an outer side surface of the one sidewall portion of the first mold is substantially constant.
