Abstract

Disclosed are a display module and a television, the display module including: a back plate including a back plate body and a side wall, the back plate body and the side wall being integrally formed and together defining a mounting space, a connecting rib parallel to the back plate body being integrally formed on an inside surface of the side wall; a display screen, an edge of an inside surface of the display screen being fixed to the connecting rib; and an optical film set mounted in the mounting space.

First claim

What is claimed is:

1. A display module, comprising:
a back plate comprising a back plate body and a side wall, the back plate body and the side wall being integrally formed and together defining a mounting space, a connecting rib parallel to the back plate body being integrally formed on an inside surface of the side wall;
a display screen, an edge of an inside surface of the display screen being fixed to the connecting rib;
an optical film set mounted in the mounting space;
wherein the optical film set comprises a first film adjacent to an inner side of the display screen, and an edge of the first film is provided with a side protrusion; and
the connecting rib is provided with a mounting sink communicating with the mounting space, and the side protrusion is clamped into the mounting sink.

2. The display module of claim 1 , wherein:
the back plate body, the side wall and the connecting rib are integrally injection molded or integrally die-casted; or
the back plate body, the side wall and the connecting rib are integrally injection molded through thermal conductive plastic; or
the back plate body, the side wall and the connecting rib are integrally injection molded through ordinary plastic, and the back plate is provided with a cooling fin or a semiconductor chilling fin.

3. The display module of claim 1 , wherein:
the edge of the inside surface of the display screen is adhered to an outer surface of the connecting rib.

4. The display module of claim 1 , wherein:
a free end surface of the side wall is higher than or flush with an outer surface of the display screen.

5. The display module of claim 1 , wherein a depth of the mounting sink is not less than a thickness of the side protrusion.

6. The display module of claim 1 , wherein:
a hanging hole is provided on the side protrusion, a hanging protrusion is provided on the mounting sink, and the hanging hole is hooked with the hanging protrusion; or
the side protrusion is adhered to the mounting sink; or
an area of the mounting sink is greater than an area of the side protrusion; or
the hanging hole is larger than the hanging protrusion.

7. A display module, comprising:
a back plate comprising a back plate body and a side wall, the back plate body and the side wall being integrally formed and together defining a mounting space, a connecting rib parallel to the back plate body being integrally formed on an inside surface of the side wall;
a display screen, an edge of an inside surface of the display screen being fixed to the connecting rib;
an optical film set mounted in the mounting space; and
wherein the optical film set comprises a light guide plate provided on an inner side of the display screen, a positioning member is provided on an inner side of the side wall, the positioning member is located between the connecting rib and the back plate body, and an side edge of the light guide plate is abutted against the positioning member.

8. The display module of claim 7 , wherein a portion of the inside surface of the side wall located inside the connecting rib is located more outside than a portion of the inside surface of the side wall located outside the connecting rib.

9. The display module of claim 7 , wherein:
the positioning member is mounted on the inside surface of the side wall; or
the positioning member is mounted on an inside surface of the back plate body, and the positioning member is adjacent to the side wall; or
the positioning member is adhered to or detachably mounted on the back plate.

10. The display module of claim 7 , wherein:
the positioning member comprises a first positioning block attached to the inside surface of the side wall, and a second positioning block formed by bending and extending from a side of the first positioning block close to the back plate body; and
a free end of the second positioning block is abutted against the side edge of the light guide plate.

11. The display module of claim 7 , wherein:
a free end of the connecting rib is provided with a positioning notch at a position corresponding to the positioning member; or
the positioning member is configured as an elastic positioning member; or
the positioning member is configured as a rubber member or a silicone member; or
the positioning member is configured as a white rubber member.

12. A television, comprising a display module, the display module comprising:
a back plate comprising a back plate body and a side wall, the back plate body and the side wall being integrally formed and together defining a mounting space, a connecting rib parallel to the back plate body being integrally formed on an inside surface of the side wall;
a display screen, an edge of an inside surface of the display screen being fixed to the connecting rib;
an optical film set mounted in the mounting space;
wherein the optical film set comprises a first film adjacent to an inner side of the display screen, and an edge of the first film is provided with a side protrusion; and
the connecting rib is provided with a mounting sink communicating with the mounting space, and the side protrusion is clamped into the mounting sink.

13. The television of claim 12 , wherein:
the back plate body, the side wall and the connecting rib are integrally injection molded or integrally die-casted; or
the back plate body, the side wall and the connecting rib are integrally injection molded through thermal conductive plastic; or
the back plate body, the side wall and the connecting rib are integrally injection molded through ordinary plastic, and the back plate is provided with a cooling fin or a semiconductor chilling fin.

14. The television of claim 12 , wherein:
the edge of the inside surface of the display screen is adhered to an outer surface of the connecting rib.

15. The television of claim 12 , wherein:
a free end surface of the side wall is higher than or flush with an outer surface of the display screen.

16. The television of claim 12 , wherein:
a hanging hole is provided on the side protrusion, a hanging protrusion is provided on the mounting sink, and the hanging hole is hooked with the hanging protrusion; or
the side protrusion is adhered to the mounting sink; or
an area of the mounting sink is greater than an area of the side protrusion; or
