Abstract: 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.

Abstract: A foldable display apparatus includes: a display panel; first and second set housings arranged in a first direction and supporting the display panel; and a hinge assembly disposed between and connected to the first and second set housings. The hinge assembly is configured to: rotate the first and second set housings inward to in-fold the display panel so that the display panel is disposed between the first set housing and the second set housing; rotate the first and second set housings outward to out-fold the display panel so that the first set housing and the second set housing are disposed between the out-folded display panel; and position the first and second set housings flat to unfold the display panel so that the display panel is flat on the first set housing, the second set housing, and the hinge assembly.

Abstract: 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.
