Abstract

An optical film, a display screen assembly and a display device are disclosed. The optical film includes a light transmitting film and a light blocking film; the light transmitting film is a double-sided adhesive film, and the light blocking film is a flexible film and is connected with a periphery of the light transmitting film.

Claims (36)

1. An optical film, comprising: a light transmitting film and a light blocking film, wherein

the light transmitting film is a double-sided adhesive film; and

the light blocking film is a flexible film and is connected with a periphery of the light transmitting film,

wherein the light blocking film comprises a first light blocking sub-film and a second light blocking sub-film attached with each other,

both of the first light blocking sub-film and the second light blocking sub-film are connected with the periphery of the light transmitting film, and

at least part of the first light blocking sub-film is detachable from the second light blocking sub-film, so that the at least part of the first light blocking sub-film is separated from the second light blocking sub-film while at least another part of the first light blocking sub-film being in contact with the second light blocking sub-film.

2. The optical film according to claim 1 , wherein a plurality of light blocking films is provided,

the light blocking films are each connected with the periphery of the light transmitting film, and are uniformly distributed along the periphery of the light transmitting film.

3. The optical film according to claim 2 , wherein the light transmitting film is in a quadrangle shape and has four side edges,

the number of the light blocking films is four, each of the four light blocking films has a first side edge, and first side edges of the four light blocking films are connected with the four side edges of the light transmitting film in one-to-one correspondence.

4. The optical film according to claim 3 , wherein a length of the first side edge of each of the four light blocking films is as same as a length of the corresponding side edge of the light transmitting film.

5. The optical film according to claim 1 , wherein the light blocking film is provided with a moisture-oxygen barrier layer.

6. The optical film according to claim 1 , wherein the light blocking film is an adhesive film.

7. The optical film according to claim 1 , wherein the light transmitting film is an Optically Clear Adhesive (OCA) film.

8. A display screen assembly, comprising a cover plate, a display panel and the optical film according to claim 1 ,

the cover plate and the display panel are arranged in lamination, the light transmitting film is disposed between the cover plate and the display panel, and the light blocking film is connected with a side surface of the display panel facing away from the cover plate so as to encapsulate at least part of the side surface of the display panel.

9. The display screen assembly according to claim 8 , further comprising a touch panel,

the touch panel and the display panel are arranged in lamination,

the touch panel is located between the cover plate and the display panel, and

the light transmitting film is disposed between the cover plate and the touch panel.

10. The display screen assembly according to claim 8 , further comprising a touch panel,

the touch panel and the display panel are arranged in lamination,

the touch panel is located between the cover plate and the display panel, and

the light transmitting film is disposed between the display panel and the touch panel.

11. The display screen assembly according to claim 10 , wherein a part of the light blocking film is located between the display panel and the touch panel.

12. The display screen assembly according to claim 10 , wherein

the first light blocking sub-film is connected with a side surface of the display panel facing away from the cover plate so as to encapsulate at least part of the side surface of the display panel; the second light blocking sub-film is connected with a side surface of the cover plate close to the touch panel so as to encapsulate at least part of a side surface of the touch panel.

13. A display device, comprising the display screen assembly according to claim 8 .

14. The display screen assembly according to claim 8 , wherein a plurality of light blocking films is provided,

the light blocking films are each connected with the periphery of the light transmitting film, and are uniformly distributed along the periphery of the light transmitting film.

15. The display screen assembly according to claim 14 , wherein the light transmitting film is in a quadrangle shape and has four side edges,

the number of the light blocking films is four, each of the four light blocking films has a first side edge, and first side edges of the four light blocking films are connected with the four side edges of the light transmitting film in one-to-one correspondence.

16. The display screen assembly according to claim 15 , wherein a length of the first side edge of each of the four light blocking films is as same as a length of the corresponding side edge of the light transmitting film.

17. The display screen assembly according to claim 8 , wherein the light blocking film is provided with a moisture-oxygen barrier layer.

18. The display screen assembly according to claim 8 , wherein the light blocking film is an adhesive film.
