Abstract

A film applied to a display, a display, and a terminal, where the film includes a film body and a plurality of rectilinear protrusions, the rectilinear protrusions are distributed on a surface of the film body, and neighboring rectilinear protrusions are parallel to each other. When the film is adhered to a rear surface of a cover glass, a sense of layering and transparency of the cover glass can be enhanced, thereby effectively improving a display effect of the display.

Claims (30)

1. A film applied to a display, comprising:

a film body; and

a plurality of corrugated protrusions distributed in sequence on a surface of the film body, neighboring corrugated protrusions being parallel to each other; wherein:

the plurality of corrugated protrusions are distributed in sequence on the surface of the film body along a length direction of the film body;

a width of each of the corrugated protrusions extends along the length direction of the film body, and a length of each of the corrugated protrusions extending along a width direction of the film body is the same as a width of the film body; and

a height profile of each of the corrugated protrusions progressing from one end of the width of the film body to the other end of the width of the film body corresponds to a bell-shaped curve, seen in cross-section along the length of each of the corrugated protrusions.

2. The film of claim 1 , wherein a value range of a height of each corrugated protrusion comprises 2 microns to 20 microns.

3. The film of claim 1 , wherein a value range of a width of each corrugated protrusion comprises 20 microns to 200 microns.

4. The film of claim 1 , wherein neighboring distributed corrugated protrusions in the corrugated protrusions are spaced apart from each other by a preset distance, and a value range of the preset distance comprising 20 microns to 250 microns.

5. The film of claim 1 , wherein a cross-section of each corrugated protrusion along the length direction of the film body is arc-shaped.

6. A display, comprising:

a cover glass; and

a film adhered to the cover glass and comprising:

a film body; and

a plurality of corrugated protrusions distributed in sequence on a surface of the film body, neighboring corrugated protrusions being in parallel to each other; wherein:

the plurality of corrugated protrusions are distributed in sequence on the surface of the film body along a length direction of the filth body;

a width of each of the corrugated protrusions extends along the length direction of the film body, and a length of each of the corrugated protrusions extending along a width direction of the film body is the same as a width of the film body; and

a height profile of each of the corrugated protrusions progressing from one end of the width of the film body to the other end of the width of the filth body corresponds to a bell-shaped curve, seen in cross-section along the length of each of the corrugated protrusions.

7. A terminal, comprising a display, and the display comprising:

a cover glass; and

a film adhered to the cover glass and comprising:

a film body; and

a plurality of corrugated protrusions distributed in sequence on a surface of the film body, neighboring corrugated protrusions being in parallel to each other; wherein:

the plurality of corrugated protrusions are distributed in sequence on the surface of the film body along a length direction of the film body;

a width of each of the corrugated protrusions extends along the length direction of the film body, and a length of each of the corrugated protrusions extending along a width direction of the film body is the same as a width of the film body; and

a height profile of each of the corrugated protrusions progressing from one end of the width of the film body to the other end of the width of the film body corresponds to a bell-shaped curve, seen in cross-section along the length of each of the corrugated protrusions.

8. The display of claim 6 , wherein a value range of a height of each of the corrugated protrusions is 2 microns to 20 microns.

9. The display of claim 6 , wherein a value range of a width of each of the corrugated protrusions is 20 microns to 200 microns.

10. The display of claim 6 , wherein neighboring distributed corrugated protrusions in the corrugated protrusions are spaced apart from each other by a preset distance, and a value range of the preset distance is 20 microns to 250 microns.

11. The display of claim 6 , wherein a cross-section of each of the corrugated protrusions along the length direction of the film body is arc-shaped.
