Abstract
A flexible organic light emitting device including a flexible substrate having an active area and a pad area; an organic light emitting diode layer disposed on the active area; an adhesive layer disposed on the organic light emitting diode layer; an encapsulation substrate disposed on the adhesive layer; a cover layer disposed between the active area and the pad area; and a back film disposed on a lower surface of the flexible substrate, futher the encapsulation substrate has a curved upper surface outside the active area, also the cover layer decreases in thickness from the active area toward the pad area.
Claims18
A flexible organic light emitting device comprising:
- a flexible substrate having an active area and a pad area;
- an organic light emitting diode layer disposed on the active area;
- an adhesive layer disposed on the organic light emitting diode layer;
- an encapsulation substrate disposed on the adhesive layer;
- a cover layer disposed between the active area and the pad area;
- and
- a back film disposed on a lower surface of the flexible substrate,
- wherein the encapsulation substrate has a curved upper surface outside the active area,
- wherein the cover layer decreases in thickness from the active area toward the pad area.
A flexible organic light emitting device comprising:
- a flexible base substrate having an active area and a pad area;
- a thin film transistor disposed on the active area;
- an organic light emitting diode layer disposed on the active area;
- an encapsulation film disposed on the thin film transistor and the organic light emitting diode layer to protect the thin film transistor and the organic light emitting diode layer;
- a cover layer disposed between the active area and the pad area;
- and
- a back film disposed on a lower surface of the flexible base substrate,
- wherein the cover layer includes a first portion adjacent to the active area and a second portion adjacent to the pad area, the first portion being thicker than the second portion.
