  • Publication number: 20240134472
    Abstract: A display apparatus may include a display area and a non-display area with a cutting surface, a light emitting diode, an encapsulation structure in the display area and a part of the non-display area, a touch structure on the encapsulation structure and comprising first and second touch dielectric layers and first and second electrodes, a routing line formed of a same layer and same material as the second touch electrode, and a second touch pad disposed on a first touch pad and formed of a same layer and same material as the routing line and the second touch electrode. The first touch pad may be formed of a same layer and same material as the source or drain electrode of a transistor. The second touch pad may be connected to the first touch pad via an opening in the at least one of the first and second touch dielectric layers.

  • Patent number: 9626063
    Abstract: A flexible organic light emitting display device is provided. The flexible organic light emitting display device comprises a first flexible substrate and a second flexible substrate spaced apart from the first flexible substrate, a first touch line unit connected with a first pad unit on the first flexible substrate at the peripheral area, a second touch line unit connected with a second pad unit on the second flexible substrate at the peripheral area and a gap balancing conductive element included in a conductive adhesive layer configured to electrically connect the first pad unit and the second pad unit for maintaining a second gap on the basis of a first gap. The first flexible substrate and the second flexible substrate are configured to have the first gap at a display area and the second gap at a peripheral area surrounding the display area.
