Abstract
Provided is an organic light emitting display module including an active area, a pad area, and a boundary area between the active area and the pad area. Unlike the active area and the pad area, since the boundary area does not include an inorganic layer, less stress is applied to the boundary area when the boundary area is bent. Display panel pads and touch sensing member pads are disposed at the same height without having a height difference therebetween. Thus, a dummy pad may be added to remove the height difference between the display panel pads and the touch sensing member pads.
Claims18
A display device comprising:
- a display panel comprising:
- a base layer;
- a circuit layer disposed on the base layer;
- a display device layer disposed on the circuit layer;
- and an encapsulation layer disposed on the display device layer;
- and
- a touch sensing member directly disposed on the encapsulation layer and comprising:
- a conductive pattern;
- and a first insulation layer overlapping with the conductive pattern and disposed on the encapsulation layer,
- wherein the circuit layer comprises:
- a first lower pad electrically connected to the display device layer and disposed on the base layer;
- a second lower pad spaced apart from the first lower pad in a plan view and disposed on the base layer;
- a first upper pad disposed on the first lower pad;
- a second upper pad electrically connected to the conductive pattern and disposed on the second lower pad;
- and
- a second insulation layer disposed between the first lower pad and the first upper pad and between the second lower pad and the second upper pad,
- wherein the first upper pad is electrically connected to the first lower pad.
A display device comprising:
- a display panel comprising:
- a base layer;
- a plurality of pads disposed on the base layer;
- an integrated circuit disposed on the base layer;
- a light emitting device disposed on the base layer;
- and an encapsulation layer encapsulating the light emitting device;
- and
- a touch sensing member directly disposed on the encapsulation layer and comprising:
- a conductive pattern;
- and an insulation layer overlapping with the conductive pattern and disposed on the encapsulation layer,
- wherein the pads are arranged in one direction and comprise:
- display panel pads;
- and touch sensing member pads spaced apart from each other in the one direction with the display panel pads interposed therebetween,
- wherein each of the display panel pads comprises:
- a first lower pad disposed on the base layer;
- and a first upper pad disposed on the first lower pad,
- wherein each of the touch sensing member pads comprises:
- a second lower pad spaced apart from the first lower pad in a plan view;
- and a second upper pad disposed on the second lower pad, and
- wherein the insulation layer is disposed between the first lower pad and the first upper pad and between the second lower pad and the second upper pad, and the first upper pad is electrically connected to the first lower pad.
