A light-emitting device can be folded in such a manner that a flexible light-emitting panel is supported by a plurality of housings which are provided spaced from each other and the light-emitting panel is bent so that surfaces of adjacent housings are in contact with each other. Furthermore, in the light-emitting device, in which part or the whole of the housings have magnetism, the two adjacent housings can be fixed to each other by a magnetic force when the light-emitting device is used in a folded state.

A cover window includes glass including a folding portion of a folding area, a planar portion, and a boundary portion between the folding portion and the planar portion, the boundary portion having a thickness that gradually becomes greater than a thickness of the folding portion as farther from the folding portion and having inclination with respect to the planar portion, and a filler disposed on a first surface of the glass. The inclination is an acute angle defined when a virtual line which is parallel to the planar portion and meets the folding portion meets the boundary portion, and is less than about 1°. A difference between a refractive index of the filler and a refractive index of the glass is within about 0.07.

A display device is disclosed.

A virtual display apparatus includes: a flexible display component layer having a light exit surface and a non-light exit surface opposite to the light exit surface; a lens layer disposed at the light exit surface of the flexible display component layer, and configured to converge light; a curvature adjustment layer disposed on the non-light exit surface of the flexible display component layer. The lens layer has a first surface facing the flexible display component layer, and the first surface of the lens layer and the light exit surface of the flexible display component layer have a gap therebetween. The curvature adjustment layer is configured to deform in response to at least one deformation signal, so as to adjust distances between the first surface of the lens layer and different positions of the light exit surface of the flexible display component layer along a thickness direction of the lens layer.

A stretchable electronic device includes a first electronic unit including a first light emitting element, a second electronic unit including a second light emitting element and disposed adjacent to the first electronic unit, and an elasticity layer having a connecting region connecting the first display unit and the second display unit. In a top view of the stretchable electronic device, a size difference between the connecting region before stretching and the connecting region after stretching is greater than a size difference between the first electronic unit before stretching and the first electronic unit after stretching.

Provided is a display device including a display module, an anti-reflection layer, and a bending protection layer. The display module includes a first area, a second area, and a bending area disposed between the first area and the second area and having a predetermined curvature radius. The bending protection layer includes a first portion overlapping at least the first area and a second portion overlapping at least the bending area. The first portion has a maximum thickness in a range from about 40 μm to about 85 μm, a maximum inclined angle in a range from about 10° to 30°, and an elastic modulus in a range from about 50 MPa to about 300 MPa.

A display device includes a display module including a first non-folding region, a second non-folding region, and a folding region disposed between the first and second non-folding regions, a first body disposed on the first non-folding region, a second body disposed on the second non-folding region, a plurality of rotation pin units connected to the first and second bodies to provide a biaxial rotation axis, which is overlapped with the folding region, to the first and second bodies, and a plurality of gears which rotate in conjunction with the rotation pin units. The plurality of gears is disposed on the rotation pin units.

A display apparatus includes a display module, a support configured to rotate and support the display module, and a mounting device configured to mount a mobile device on the display module. The mobile device is configured to be paired with the display module. The mounting device includes a mounting portion including a mounting groove having a shape corresponding to a frame forming borders of the display module. The mounting portion is coupled to the frame when the frame is inserted into the mounting groove, and an accommodating portion is positioned below the mounting portion, and accommodates the mobile device such that the mobile device is mounted on the display module.

An electronic device is provided. The electronic device includes a curved screen, a housing that matches the curved screen to form an accommodating cavity, and a first button. The curved screen includes a plane portion and a curved portion. A first end of the curved portion is connected to the plane portion. The curved portion bends and extends toward the housing. A second end of the curved portion extends toward the accommodating cavity. The first button includes a pressure sensor and a trigger assembly. The pressure sensor is disposed in the accommodating cavity, the trigger assembly is disposed at the second end of the curved portion, and the trigger assembly and the pressure sensor are disposed at an interval. In a case that the curved portion receives a target pressing operation, the second end of the curved portion drives the trigger assembly to contact and trigger the pressure sensor.
