Abstract

The present application relates to an input sensing unit and a display device using the same. The input-sensing unit including a first conductive layer, a first organic layer, a second conductive layer, and a second organic layer sequentially stacked one over another, in which the first organic layer includes a first base resin and a first hollow polymer, and the second organic layer includes a second base resin and a second hollow polymer.

Claims (37)

1. An input-sensing unit, comprising:

a first conductive layer, a first organic layer, a second conductive layer, and a second organic layer sequentially stacked one over another,

wherein:

the first organic layer comprises a first base resin and a first hollow polymer; and

the second organic layer comprises a second base resin and a second hollow polymer.

2. The input-sensing unit of claim 1 , wherein:

the first and second base resins comprise substantially the same material; and

the first and second hollow polymers comprise substantially the same material.

3. The input-sensing unit of claim 1 , wherein the first and second organic layers have dielectric constants ranging from about 1.3 to about 3.0.

4. The input-sensing unit of claim 3 , wherein a content of the first hollow polymer in the first organic layer and a content of the second hollow polymer in the second organic layer are each in a range of about 10 wt % to about 70 wt %.

5. The input-sensing unit of claim 1 , wherein:

the first hollow polymer comprises a first shell that defines a first hollow therein;

the second hollow polymer comprises a second shell that defines a second hollow therein; and

each of the first and second shells comprises at least one of polyimide, polyurethane, polystyrene, acrylic resin, and epoxy resin.

6. The input-sensing unit of claim 5 , wherein each of the first and second hollows have a mean diameter ranging from about 20 nm to about 150 nm.

7. The input-sensing unit of claim 1 , wherein at least one of the first and second conductive layers comprises at least one of molybdenum, silver, titanium, copper, aluminum, alloys thereof, indium tin oxide, indium zinc oxide, zinc oxide, and indium tin zinc oxide.

8. A display device, comprising:

a display panel;

a first conductive layer disposed on the display panel;

a first organic layer disposed on the first conductive layer;

a second conductive layer disposed on the first organic layer; and

a second organic layer disposed on the second conductive layer,

wherein:

the first organic layer comprises a first base resin and a first hollow polymer; and

the second organic layer comprises a second base resin and a second hollow polymer.

9. The display device of claim 8 , wherein:

the first and second base resins comprise substantially the same material; and

the first and second hollow polymers comprise substantially the same material.

10. The display device of claim 8 , wherein:

the display panel comprises a light-emitting device layer and a thin encapsulation layer covering the light-emitting device layer; and

the first conductive layer is directly disposed on the thin encapsulation layer.

11. The display device of claim 8 , further comprising an inorganic layer disposed on the display panel,

wherein the first conductive layer is directly disposed on the inorganic layer.

12. The display device of claim 8 , wherein the display panel comprises a flexible display panel.

13. The display device of claim 8 , wherein:

at least one of the first and second conductive layers comprises a plurality of conductive patterns; and

the plurality of conductive patterns comprise a sensing electrode.
