Abstract: A foldable display device includes a display panel, a back plate disposed under the display panel, and a support structure disposed under the back plate and having a bendable area and non-bendable areas disposed on sides of the bendable area. The support structure includes a first support plate having a plurality of opening patterns disposed in the bendable area, and a second support plate disposed on the first support plate and made of a different material from a material of the first support plate. One of the back plate and the second support plate includes a polymer film having a maximum reflectance within a wavelength range of approximately 400 nm to 500 nm. The other one of the back plate and the second support plate includes a polymer film having a maximum light absorbance within a wavelength range of approximately 400 nm to 500 nm.

Abstract: A headset including an in-ear microphone is disclosed, the headset including a first frame including a first surface toward a first direction, a second surface toward a second direction opposite to the first direction, and a side surface surrounding at least part of a space between the first surface and the second surface, a speaker seating portion formed by recessing by a specific depth from a first portion of the first surface toward the second surface, a space formed between the speaker seating portion and the second surface, a speaker hole penetrated from the speaker seating portion to the space, a microphone hole penetrated from a second portion of the first surface to the space, an acoustic hole formed by penetrating the second surface from the space, a speaker seated in the speaker seating portion, a first printed circuit board disposed on the second portion and having a via hole connected with the microphone hole, a second printed circuit board electrically connected with the first printed circuit boa

Abstract: A foldable display apparatus comprises a display panel including a folding area and a non-folding area at one or more sides of the folding area; and a cover window on the display panel. The cover window includes a glass substrate including a plurality of patterns at the folding area, and a protective layer between the glass substrate and the display panel. Each of the plurality of patterns includes a plurality of protrusions.

Abstract: A foldable display apparatus includes a display panel; a first plate under the display panel; and a support structure under the first plate and having a foldable area and two non-foldable areas respectively on both opposing sides of the foldable area. The support structure includes a first support plate having a plurality of opening patterns defined in the foldable area; a second support plate above the first support plate and including a material different from a material of the first support plate; and a first adhesive layer between the first support plate and the second support plate. The first adhesive layer has: first portions respectively in each of the non-foldable areas of the support structure; and a second portion in the foldable area of the support structure. The second portion has a higher degree of cure than a degree of cure of each of the first portions.
