Display device

A flexible display apparatus including a display substrate having a bending area that is bendable in one direction; a thin film encapsulation (TFE) layer on the display substrate; and at least one insulating dam on the display substrate, wherein the at least one insulating dam is outside the bending area.

Flexible display apparatus

A display apparatus includes a substrate having a first area, a second area, and a third area, the second area being between the first and third areas, a display unit on the substrate in the first area, and an encapsulation layer covering the display unit in the first area and extending into the second area, the encapsulation layer including a first inorganic layer, a second inorganic layer, an organic layer between the first and second inorganic layers in the first area, and a plurality of organic patterns spaced apart from each other at certain intervals in the second area. The first and third areas of the substrate are bent with respect to each other at a predetermined angle, other than a straight angle, with the second area bent therebetween, and the plurality of organic patterns are in the second area that is bent toward the bottom of the substrate.

Display apparatus with bent area including spaced patterns

A flexible display device includes: a flexible substrate; a thin-film transistor on the flexible substrate; a passivation film covering the thin-film transistor; and a display element on the passivation film and electrically connected to the thin-film transistor. The passivation film includes a material exhibiting a shear-thickening phenomenon.

Flexible display device

A foldable display is disclosed. In one aspect, the foldable display includes a display panel including: a plurality of flat regions and a folding region interposed between the flat regions. Each of the flat regions includes a fixed region and a semi-fixed region interposed between the fixed region and the folding region. The foldable display also includes a plurality of substrates respectively attached to the flat regions and a plurality of fixed adhesive members respectively interposed between the fixed regions and the substrates. The fixed adhesive members respectively attach the substrates to the fixed regions. The foldable display further includes a plurality of semi-fixed adhesive members respectively interposed between the semi-fixed regions and the substrates. The semi-fixed adhesive members are configured to respectively attach/detach the semi-fixed adhesive regions to/from the substrates based on the degree to which the display panel is folded.

Foldable display

A method of manufacturing a curved display device is disclosed. In one aspect, the method includes providing a frame, providing a flexible display panel and attaching a first area of the flexible display panel to the frame. The method also includes attaching a second area of the flexible display panel to the frame, wherein the providing of the flexible display panel comprises attaching a release paper to a surface of the flexible display panel, the release paper comprising first and second release areas respectively corresponding to the first and second areas of the flexible display panel. The method further includes removing the first release area from the flexible display panel before attaching the first area and removing the second release area from the flexible display panel before attaching the second area.

Method of manufacturing curved display device

A rollable display device includes a display module, a window member, a housing in which the display module and the window member are configured to be rolled up and stored, the housing having a slot through which the display module and the window member are configured to move in and out, a first rotary member disposed inside the housing configured to roll up the display module, and a second rotary member disposed inside the housing, spaced from the first rotary member, and configured to roll up the window member.
