Abstract

The present disclosure provides an antistatic film and a polarizer attachment device. The antistatic film includes a static electricity elimination layer configured to eliminate static charges and an adhesive layer arranged at one surface of the static electricity elimination layer. According to the present disclosure, it is able to directly attach the antistatic film onto a bearing platform of the polarizer attachment device.

First claim

What is claimed is:

1 . An antistatic film, comprising a static electricity elimination layer configured to eliminate static charges and an adhesive layer arranged at one surface of the static electricity elimination layer.

2 . The antistatic film according to claim 1 , wherein the static electricity elimination layer is configured to eliminate the static charges through electrostatic neutralization.

3 . The antistatic film according to claim 2 , wherein a material of the static electricity elimination layer comprises high molecular weight polyethylene.

4 . The antistatic film according to claim 1 , wherein an adhesive force between the adhesive layer and the static electricity elimination layer is greater than an adhesive force between the adhesive layer and a bearing platform onto which the antistatic film is attached.

5 . The antistatic film according to claim 1 , wherein the adhesive layer comprises a substrate, and a first adhesive and a second adhesive are coated onto two surfaces of the substrate respectively.

6 . The antistatic film according to claim 5 , wherein a material of the substrate comprises cotton paper, polyethylene terephthalate (PET), polyvinyl chloride (PVC), non-woven fabrics or foam, and the first adhesive and the second adhesive are each acrylic adhesive or acrylic latex.

7 . The antistatic film according to claim 1 , wherein a frictional coefficient between a surface of the static electricity elimination layer and a surface of a display panel which is to be subjected to a static electricity elimination is in a range from 0.1 to 1.

8 . The antistatic film according to claim 1 , wherein a surface hardness of the static electricity elimination layer is less than a surface hardness of the display panel which is to be subjected to the static electricity elimination.

9 . The antistatic film according to claim 5 , wherein a material of the first adhesive is different from a material of the second adhesive.

10 . A polarizer attachment device, comprising the antistatic film according to claim 1 .

11 . The polarizer attachment device according to claim 10 , wherein the static electricity elimination layer is configured to eliminate static charges through electrostatic neutralization, and the polarizer attachment device further comprises a detection apparatus configured to detect a resistance of a surface of the static electricity elimination layer.

12 . The polarizer attachment device according to claim 11 , wherein a material of the static electricity elimination layer comprises high molecular weight polyethylene.

13 . The polarizer attachment device according to claim 10 , further comprising an adsorption platform onto which the antistatic film is attached.

14 . The polarizer attachment device according to claim 13 , wherein an adhesive force between the adhesive layer and the static electricity elimination layer is greater than an adhesive force between the adhesive layer and the adsorption platform.

15 . The polarizer attachment device according to claim 10 , wherein the adhesive layer comprises a substrate, and a first adhesive and a second adhesive are coated onto two surfaces of the substrate respectively.

16 . The polarizer attachment device according to claim 15 , wherein a material of the substrate comprises cotton paper, polyethylene terephthalate (PET), polyvinyl chloride (PVC), non-woven fabrics or foam, and the first adhesive and the second adhesive are each acrylic adhesive or acrylic latex.

17 . The polarizer attachment device according to claim 15 , wherein a material of the first adhesive is different from a material of the second adhesive.
