Abstract: The organic light emitting display device includes a flexible substrate, a thin-film transistor on the flexible substrate, a first anode on the thin-film transistor, a second anode on the same plane with the first anode and spaced apart from the first anode so as to surround the first anode, an organic light emitting layer on the first anode and the second anode, and a cathode on the organic light emitting layer. The second anode includes an opening where the first anode is encompassed therein. The shape of the first anode and the second anode and arrangement thereof reduces a segment length of an anode in a bending direction of the organic light emitting display device, and, thus, occurrence of cracks in the anode can be minimized.

Abstract: There is provided a flexible display having a new wire structure and a new insulating layer structure. A flexible display includes a flexible substrate having a first area and a second area. The second area is curved in a non-zero angle relative to the plane of the first area. The flexible display further includes a plurality of wires that extend over from the first area to the second area of the flexible substrate. Each of the wires is covered by an upper insulating pattern, which is separated from other upper insulating pattern. Each upper insulating pattern covering the wire has substantially the same trace pattern shape of the corresponding wire thereunder. Accordingly, by adopting the above-described wire structure and upper insulating layer structure, crack generation and propagation in the wires and the insulating layers from bending of the flexible display can be minimized.

Abstract: Embodiments of the present disclosure can significantly reduce the non-display area of a flexible OLED display, which would otherwise be covered by a cosmetic trim such as a bezel or an opaque. As such, an electronic device with a display having minimized border area can be provided. This makes it possible to reduce the overall size of the electronic device without sacrificing the size of the display therein. Such a reduction in size of the bezel was achieved by bending the flexible substrate near its edge using an insert member.
