Abstract

Embodiments of the present disclosure provide a display device, comprising a display module. The display module comprises a back plate. A first accommodating part and a second accommodating part which are stacked and communicated with each other are formed on one side of the back plate. The first accommodating part is configured to accommodate a backlight component, and the second accommodating part is configured to accommodate a liquid crystal screen.

First claim

What is claimed is:

1 . A display device comprising a display module, the display module comprising a backplate that comprises: a first accommodating portion configured to accommodate a backlight component; and a second accommodating portion, stacked on and connected with the first accommodating portion, configured to accommodate a liquid crystal screen,
wherein the display module has a display surface and a back surface that are relatively arranged; the back side of the display module is provided with a plurality of device mounting areas; the display device comprises a plurality of back shells correspondingly arranged in the plurality of device mounting areas; each of the back shells is provided with a device mounting portion, and the back shells and the device mounting area are enclosed to form a device mounting cavity.

2 . The display device of claim 1 , wherein the backplate comprises a bottom wall and a side wall thereon; an inner surface of the side wall is provided with a flange portion that is opposite to the bottom wall; the bottom wall and the side wall are enclosed to form an accommodating cavity, and the flange portion separates the accommodating cavity into the first accommodating portion and the second accommodating portion.

3 . The display device of claim 2 , wherein the flanging portion is bent along a direction close to the bottom wall to form a folding structure.

4 . The display device of claim 3 , wherein the liquid crystal screen is arranged on one side surface of the folding structure far away from the backlight component, and the liquid crystal screen and the folding structure are bonded through an adhesive.

5 . The display device of claim 3 , wherein a upper part of the flange portion facing the bottom wall has a plane structure.

6 . The display device of claim 3 , wherein the folding edge structure is left with a gap.

7 . The display device of claim 3 , wherein one side of the flange facing the bottom wall is provided with a protective layer which is made of a Mylar sheet, a plastic layer, a rubber layer and a sponge layer.

8 . The display device of claim 2 , wherein one side of the flange facing the bottom wall is provided with a protective layer which is made of a Mylar sheet, a plastic layer, a rubber layer and a sponge layer.

9 . The display device according to claim 7 , wherein a thickness of the protective layer ranges between 0.2 and 0.5 mm.

10 . The display device of claim 1 , wherein the plurality of device mounting areas are defined on one side of the backplate far away from the display surface.

11 . The display device of claim 1 , wherein the plurality of device mounting areas are arranged in the downside area of the display module along its height direction, and the plurality of device mounting areas are sequentially arranged along a width direction of the display module.

12 . The display device of claim 11 , wherein one side edge of the back shell and the lower edge of the display module along its height direction are flush.

13 . The display device of claim 11 , wherein the surface of one side of the back shell, far away from the display surface, and the back surface of the display module are shared in a plane or a curved surface.

14 . The display device of claim 1 , further comprising a side frame, wherein the display module has a periphery surface connecting the display surface and the back surface, and the side frame is arranged on a periphery of the display module and an edge of the display surface.

15 . The display device of claim 14 , wherein the side frame is only arranged in a local area on the periphery of the display module.

16 . The display device of claim 14 , wherein the back shell and the side frame are buckled and connected.

17 . The display device of claim 14 , further comprising a driving circuit arranged on the periphery of the display module and a heat-dissipating sheet arranged between the driving circuit and the side frame.

18 . The display device of claim 17 , wherein the heat-dissipating sheet is made of a soaking material selected from at least one of a graphite sheet, a graphene film, a thermally conductive coating material, a ceramic material, a thermally conductive gel, and a phase-change material (PCM).

19 . The display device of claim 1 , wherein the backlight component comprises a backlight source on the backplate, and an optical film on one side of the backlight that is far away from the backplate.
