Provided is a foldable display device. The display device includes a display panel including a folding area and non-folding areas, a back plate disposed under the display panel, a first support layer disposed under the back plate and having an opening pattern in a portion thereof corresponding to the folding area, and an impact absorbing layer disposed under the first support layer. The impact absorbing layer includes a first portion corresponding to the folding area and a second portion corresponding to the non-folding areas, and a modulus of the first portion is greater than a modulus of the second portion. Accordingly, even when a point impact is applied to the folding area, the point impact is converted into a surface impact, so that damage to the display or touch panels by the point impact can be prevented more effectively. Consequently, impact resistance characteristics of the display device may be improved.

Foldable display device

A foldable display device includes a foldable display panel and a foldable cover window disposed on the foldable display panel. The foldable cover window includes a flexible film and a first hard coating layer located on the flexible film with the first hard coating layer including a base material in combination with a linker material. The base material is a siloxane-based resin and the linker material is one of: a urethane-acrylic-based linker, an acrylic-based linker, and an epoxy-based linker.

Provided is a display device. The display device includes a display panel; a support substrate supporting the display panel below the display panel and including a plurality of opening patterns; and an adhesive layer which is disposed on the support substrate and includes a plurality of first areas provided so as to correspond to each of the plurality of opening patterns and a second area enclosing the plurality of first areas and having a Young's modulus lower than that of the plurality of first areas. Each of the first area is larger than the corresponding opening pattern.

Display device

Provided is a foldable display device that includes a display panel having a folding area and non-folding areas. The device includes a back plate under the display panel, a first support layer under the back plate and having an opening pattern in a portion thereof corresponding to the folding area, and an impact absorbing layer under the first support layer. The impact absorbing layer includes a first portion corresponding to the folding area and a second portion corresponding to the non-folding areas, and a modulus of the first portion is greater than a modulus of the second portion. Accordingly, even when a point impact is applied to the folding area, the point impact is converted into a surface impact, so that damage to the display panel or the touch panel by the point impact can be prevented more effectively. Consequently, impact resistance characteristics of the display device may be improved.

A foldable display apparatus includes a display panel having a light-emitting element disposed thereon, a cover window disposed on top of the display panel, a bottom plate disposed beneath the display panel, a bellows for supporting at least a portion of the bottom plate, a first support coupled with one end of the bellows, and an edge coupled with the other end of the bellows.

Foldable display apparatus

A sound apparatus includes a first vibration member, a second vibration member adjacent to the first vibration member, a third vibration member adjacent to the second vibration member, a first vibration apparatus configured to vibrate the first vibration member and the second vibration member and output a sound of a first pitched sound band and a sound of a second pitched sound band which differ, and a second vibration apparatus disposed at a rear surface of the third vibration member and configured to vibrate the third vibration member and output a sound of a third pitched sound band which differs from the sound of the first pitched sound band.

Sound apparatus and apparatus including the same

Provided is a foldable display device. The display device comprises a display panel including a folding area and non-folding areas on both sides of the folding area, a back plate disposed under the display panel, a first support layer disposed under the back plate and having an opening pattern in a portion thereof corresponding to the folding area, and an impact absorbing layer disposed under the first support layer. The impact absorbing layer includes a first portion corresponding to the folding area and a second portion corresponding to the non-folding areas, and a modulus of the first portion is greater than a modulus of the second portion. Accordingly, even when a point impact is applied to the folding area, the point impact is converted into a surface impact, so that damage to the display panel or the touch panel by the point impact can be prevented more effectively. Consequently, impact resistance characteristics of the display device may be improved.

A display device includes a display panel, a back plate disposed below the display panel, and a deformation prevention structure disposed below the back plate. The display panel, the back plate, and the deformation prevention structure are bendable in at least one bendable area. The deformation prevention structure has higher modulus than either the display panel or the back plate in the at least one bendable area. The display device is not deformed even after being repeatedly bent.

Bendable display device having improved flatness and damage prevention

A foldable display device includes a display panel configured to be folded around a folding axis. The display panel includes spacers disposed in a non-folding area and a folding area, and the spacers may have different sizes or densities. Dimensions of the spacers may be in a direction of the folding axis or intersect the direction of the folding axis. The display panel also includes pixels in an active area that overlap with the spacers, which may help reduce peeling, cracking, defects, or reduction in pixel brightness due to folding of the display device.
