A display device includes a display module, a support plate disposed under the display module and including a first support plate, a second support plate, and a plurality of support joints disposed between the first and second support plates, and a cover film disposed under the support plate and covering the support joints. The support joints are not attached to the cover film.

A manufacturing method of a window includes: providing a substrate; placing a plurality of masks above the substrate; adjusting positions of the plurality of masks to expose a target area of the substrate; spraying a coating material to the target area of the substrate exposed by the plurality of masks; and heat-treating the substrate and the coating material sprayed on the substrate to form the window.

A foldable display device may include: a display panel displaying an image; a cover window over the display panel; and a back plate under the display panel. The back plate may include a plate top having a plurality of holes, a plate bottom having at least one groove corresponding to the plurality of holes, and an adhesive layer attaching the plate top and the plate bottom.

Methods and devices for selectively presenting a user interface for a phone application are provided. More particularly, a change in the display mode of a multiple screen device can be determined. More particularly, a presentation of a user interface for a call log of a phone application can be retained after receiving a flick in an off-screen gesture area of the device. However, a second, child window is provided in a second screen in response to receiving the flick. The second, child window provides detail information about a phone call selected in the call log.

A display device includes a display module. An adhesive member is disposed directly on the display module. A window is disposed directly on the adhesive member. The adhesive member includes a first adhesive layer disposed adjacent to the display module and having a first storage modulus at ?20? C. A second adhesive layer is disposed directly on the first adhesive layer and has a second storage modulus at ?20? ? C. The second storage modulus is greater than the first storage modulus.

A display device includes a display module including a folding display portion, a first non-folding display portion, and a second non-folding display portion, and a support plate disposed below the display module and including a folding support portion, a first non-folding support portion, and a second non-folding support portion, wherein the support plate includes a matrix portion, first fibers dispersed in the matrix portion, and second fibers dispersed in the matrix portion, the first fibers each include a plurality of first sub-fibers corresponding to the folding support portion and spaced apart at a first interval, and a plurality of second sub-fibers corresponding to the first non-folding support portion and the second non-folding support portion and spaced apart at a second interval which is smaller than the first interval.

A foldable display device may include: a display panel displaying an image; a cover window over the display panel; and a back plate under the display panel. The back plate may include a plate top having a plurality of holes, a plate bottom having at least one groove corresponding to the plurality of holes, and an adhesive layer attaching the plate top and the plate bottom.

A hinge assembly is provided. The first swing arm includes a first hinge connecting part and a first rotating part. The first swing arm is rotatable relative to the base around a first axis between the first hinge connecting part and the first rotating part. The second swing arm includes a second hinge connecting part and a second rotating part. The second swing arm is rotatable relative to the base around a second axis between the second hinge connecting part and the second rotating part. The second axis is parallel to the first axis. The slider includes a first fastening part, a second fastening part, and an extension part. The extension part is located in the guide groove. The first fastening part is movably connected to the first hinge connecting part. The second fastening part is movably connected to the second hinge connecting part.

An electronic apparatus includes a display module including a folding portion folded about a folding axis extending along a first direction and first and second non-folding portions spaced apart from each other with the folding portion interposed therebetween. A support plate is disposed on a lower side of the display module and includes openings overlapping the folding portion. An adhesive layer is disposed on an upper side of the support plate and overlaps the folding portion, the first non-folding portion, and the second non-folding portion, and a cover attached on a lower side of the support plate, and overlapping at least the folding portion. A through portion passes through the cover along a through direction, and has a depth along a third direction which is perpendicular to first and second directions. The through portion is connected to at least one of the openings.

The present invention discloses a one-side rotating arc lock which comprises an adjusting assembly arranged on a first shell and a strainer arranged on a second shell. The adjusting assembly comprises an arc adjuster rotatably connected with the first shell. The arc adjuster is provided with multiple protrusions in the circumferential direction, used for adjusting the angle between the first and the second shell. Groove is provided on the protrusion. The strainer comprises an adjusting rod which matches the groove for locking the first and the second shell. The angle between the first and the second shell is adjusted through the arc adjuster rotatably connected with the first shell, and locking of the first and the second shell is achieved through the strainer. The one-side rotating arc lock of the preset invention not only has a simple structure and easy to operate, but also facilitates adjustment of the angle.
