Abstract

A digitizer and a display apparatus including the same are provided. The digitizer includes a base layer in which a metal pattern is disposed, and a blocking layer disposed on the base layer.

First claim

What is claimed is:

1 . A digitizer comprising:
a base layer in which a metal pattern is disposed; and a blocking layer disposed on the base layer.

2 . The digitizer of claim 1 , wherein the blocking layer is black.

3 . The digitizer of claim 1 , further comprising a base planarization layer disposed between the blocking layer and the base layer.

4 . The digitizer of claim 1 , wherein the blocking layer and the base layer are integral with each other.

5 . The digitizer of claim 1 , wherein the base layer includes:
a body layer; and a pattern layer disposed on the body layer.

6 . The digitizer of claim 1 , wherein a side of the blocking layer is substantially flat.

7 . The digitizer of claim 1 , further comprising a heat-dissipating plate extended to the base layer.

8 . The digitizer of claim 7 , wherein the heat-dissipating plate is bendable.

9 . A display apparatus comprising:
a display panel including:
a first surface on which a display area is disposed; and
a second surface; and
a digitizer disposed on the second surface of the display panel, wherein the digitizer includes:
a base layer; and
a blocking layer disposed on the base layer, the blocking layer facing the second surface.

10 . The display apparatus of claim 9 , wherein the blocking layer includes at least one of polyimide and a black filler.

11 . The display apparatus of claim 9 , wherein the digitizer includes a base planarization layer disposed between the base layer and the blocking layer.

12 . The display apparatus of claim 9 , wherein the base layer includes:
a body layer; and a pattern layer disposed on the body layer, the blocking layer being disposed on the pattern layer.

13 . The display apparatus of claim 12 , wherein the base layer includes an adhesive layer disposed between the pattern layer and the blocking layer.

14 . The display apparatus of claim 9 , further comprising an optical functional layer disposed on the first surface.

15 . The display apparatus of claim 9 , further comprising a heat-dissipating plate extended to the digitizer.

16 . The display apparatus of claim 15 , wherein the heat-dissipating plate is bendable.

17 . The display apparatus of claim 15 , wherein the heat-dissipating plate includes:
a first heat-dissipating plate extended to the digitizer; and a second heat-dissipating plate extended to the first heat-dissipating plate.

18 . The display apparatus of claim 9 , wherein the display panel is flexible.

19 . The display apparatus of claim 9 , wherein a side of the digitizer facing the second surface is substantially flat.

20 . A display apparatus comprising:
a display panel including:
a first surface on which a display area is disposed; and
a second surface;
a panel-protecting member disposed on the second surface; and a digitizer disposed on the panel-protecting member.

21 . The display apparatus of claim 20 , further comprising an optical functional layer disposed on the first surface.

22 . The display apparatus of claim 20 , further comprising a cover member disposed on the first surface.

23 . The display apparatus of claim 20 , wherein the digitizer includes:
a base layer; and a blocking layer disposed on the base layer and facing the second surface.

24 . The display apparatus of claim 23 , wherein the blocking layer includes at least one of polyimide and a black filler.

25 . The display apparatus of claim 23 , wherein the digitizer includes a base planarization layer disposed between the base layer and the blocking layer.

26 . The display apparatus of claim 23 , wherein the base layer includes:
a body layer; and a pattern layer disposed on the body layer, the blocking layer being disposed on the pattern layer.

27 . The display apparatus of claim 26 , wherein the base layer includes an adhesive layer disposed between the pattern layer and the blocking layer.

28 . The display apparatus of claim 26 , further comprising a heat-dissipating plate extended to the digitizer.

29 . The display apparatus of claim 28 , wherein the heat-dissipating plate is bendable.

30 . The display apparatus of claim 28 , wherein the heat-dissipating plate includes:
a first heat-dissipating plate extended to the digitizer; and a second heat-dissipating plate extended to the first heat-dissipating plate.

31 . The display apparatus of claim 23 , wherein the display panel is flexible.

32 . The display apparatus of claim 23 , wherein one side of the digitizer facing the second surface is substantially flat.
