Abstract

A frame assembly and a display device including the frame assembly are provided. The frame assembly includes: a side frame and corresponding side plates, pressing plates and fixing plates; for at least one group of corresponding side plate, pressing plate and fixing plate, a structure as follows is provided: the side frame is fixedly connected to the side plate; the fixing plate is fixed on the side frame, and an outer surface of the fixing plate is not higher than an outer surface of the side plate; the side frame is provided with an elastic pad located on an inner side of the fixing plate, and a projection of the side frame and a projection of the elastic pad in a plane of a side surface of the side plate of the backplane facing the pressing plate is located within the side surface of the side plate facing the pressing plate. A width of the frame assembly is only a thickness of the side plate of the backplane to achieve a narrow frame design of the display device.

First claim

The invention claimed is:

1. A frame assembly, comprising:
a backplane, including a base plate and a plurality of side plates to form a mounting tank for mounting a backlight module;
a front frame, having pressing plates parallel with the base plate and corresponding to the side plates one by one, and fixing plates parallel with the side plates and corresponding to the side plates one by one; and
a side frame, located on one side of the backplane facing the pressing plates, and located on an inner side of the fixing plates, the side frame and respective side plates of the backplane being fixedly connected;
wherein, for at least one group of corresponding side plate, pressing plate and fixing plate, a structure as follows is provided: the fixing plate is fixed on the side frame, and an outer surface of the fixing plate does not extend beyond an outer surface of the side plate;
the side frame is provided with an elastic pad located on an inner side of the fixing plate, an inner surface of the elastic pad provides a first step surface for supporting and limiting a display panel, and an inner surface of the side frame and the first step surface of the elastic pad do not extend beyond an inner surface of the side plate.

2. The frame assembly according to claim 1 , wherein the side frame and the side plate coordinate to form a second step surface located on an outer side of the side frame and configured to support the fixing plate.

3. The frame assembly according to claim 1 , wherein the side frame is provided with slots having an opening facing the pressing plate, a side surface, facing away from the pressing plates, of the elastic pad contains protrusions to be plugged into the slots, and the elastic pad is mounted on the side frame through the slots and the protrusions.

4. The frame assembly according to claim 3 , wherein the elastic pad has an integral structure.

5. The frame assembly according to claim 3 , wherein the elastic pad includes a plurality of sub-elastic pads, and the plurality of sub-elastic pads are evenly distributed on the side frame.

6. The frame assembly according to claim 5 , wherein the slots provided on the side frame correspond to the sub-elastic pads one by one.

7. The frame assembly according to claim 1 , wherein, a side surface, facing away from the pressing plates, of the elastic pad contains a slot, a side surface of the side frame facing the pressing plate has a protrusion to be plugged into the slot, and the elastic pad is mounted on the side frame through the slot and the protrusion.

8. The frame assembly according to claim 1 , wherein the fixing plates are fixed on the side frame, comprising:
the fixing plates and the side frame are connected through a plurality of pairs of snaps and slots engaged with each other.

9. The frame assembly according to claim 1 , wherein a pad is set on a side surface, facing the base plate, of each of the pressing plates.

10. The frame assembly according to claim 1 , wherein a side surface, facing away from the pressing plates, of the elastic pad further has a pressing protrusion for pressing an optical membrane of the backlight module.

11. The frame assembly according to claim 1 , wherein the side frame and the backplane have an integral structure.

12. A display device, comprising a display panel and the frame assembly according to claim 1 .

13. The frame assembly according to claim 2 , wherein a side surface, facing away from the pressing plates, of the elastic pad further has a pressing protrusion for pressing an optical membrane of the backlight module.

14. The frame assembly according to claim 2 , wherein the side frame and the backplane have an integral structure.

15. The frame assembly according to claim 3 , wherein a side surface, facing away from the pressing plates, of the elastic pad further has a pressing protrusion for pressing an optical membrane of the backlight module.

16. The frame assembly according to claim 3 , wherein the side frame and the backplane have an integral structure.

17. The frame assembly according to claim 7 , wherein a side surface, facing away from the pressing plates, of the elastic pad further has a pressing protrusion for pressing an optical membrane of the backlight module.

18. The frame assembly according to claim 7 , wherein the side frame and the backplane have an integral structure.

19. The frame assembly according to claim 8 , wherein a side surface, facing away from the pressing plates, of the elastic pad further has a pressing protrusion for pressing an optical membrane of the backlight module.

20. The frame assembly according to claim 8 , wherein the side frame and the backplane have an integral structure.
