Abstract

Provided are a set and a display apparatus. The set includes a display module, a bezel, a back housing and a system board. The bezel is sleeved over a periphery of the display module. The back housing includes a first shell on a side opposite to a back plate of the display module, and a second shell adjacent to an inner peripheral surface of the bezel. One end of the second shell is connected to an edge of the first shell, and the other end of the second shell is provided with a support portion for supporting an edge of the display module so that a reserved space for accommodating the system board is formed between the display module and the first shell, and the second shell is fixedly connected to the bezel to implement configuration and assembly of the system board, thereby improving the user experience.

First claim

What is claimed is:

1. A set, wherein the set comprises a display module, a bezel, a back housing and a system board, wherein the bezel is sleeved over a periphery of the display module;
the back housing comprises a first shell on a side opposite to a back plate of the display module, and a second shell adjacent to an inner peripheral surface of the bezel,
wherein one end of the second shell is connected to an edge of the first shell, and the other end of the second shell is provided with a support portion for supporting an edge of the display module, so that a reserved space for accommodating the system board is formed between the display module and the first shell, and the second shell is fixedly connected to the bezel,
wherein the bezel has a rectangular orthographic projection on a plane where a light-emitting surface of the display module is located, with two opposite longer sides and two opposite shorter sides,
the second shell and the bezel are fixedly connected on one side of each longer side of the bezel through a plurality of first fastening screws, and the plurality of first fastening screws on the one side of each longer side of the bezel are arranged along a direction of the longer side,
wherein the bezel and the display module are fixedly connected on one side of each longer side of the bezel through a plurality of second fastening screws, and the plurality of second fastening screws on the one side of each longer side of the bezel are arranged along the direction of the longer side,
wherein a same number of second fastening screws as the first fastening screws on a same side are provided on the one side of each longer side of the bezel, and a central connection line of orthographic projections of at least some of the first fastening screws and the second fastening screws on a section of the bezel parallel to the longer side is perpendicular to an extending direction of the longer side,
wherein a protrusion protruding relative to the inner surface is provided on an inner surface of the second shell facing away from the bezel, and
wherein a threaded hole, penetrating from an end face of the protrusion facing away from the bezel to an outer surface of the second shell opposite to the bezel, is provided in the protrusion and configured for threaded engagement with one of the first fastening screws.

2. The set according to claim 1 , wherein the support portion comprises a first sub-protrusion extending from the other end of the second shell to a direction close to the display module, and a second sub-protrusion extending from one end of the first sub-protrusion close to the display module to a side of the second shell away from the bezel, wherein the second sub-protrusion abuts against an edge of the display module.

3. The set according to claim 1 , wherein the set further comprises a wireless transmission module; wherein
a hollow-out region is provided on the back plate of the display module at a position corresponding to the wireless transmission module, and the hollow-out region is configured to enable signals sent from or received by the wireless transmission module to pass through the back plate.

4. The set according to claim 3 , wherein a cover for covering the hollow-out region is provided on the back plate.

5. The set according to claim 1 , wherein a contour shape and an outer peripheral dimension of the bezel are respectively matched with a contour shape and an outer peripheral dimension of the display module.

6. The set according to claim 1 , wherein a limiting portion for covering a non-display region of a display panel is provided on a side of the bezel close to a light-emitting surface of the display panel of the display module.

7. The set according to claim 1 , wherein a distance between two adjacent first fastening screws is greater than or equal to 40 mm and less than or equal to 80 mm.

8. The set according to claim 1 , wherein a plurality of fixing posts are provided on a side surface of the first shell close to the display module, and the plurality of fixing posts is configured to fix the system board so that a gap is reserved between the system board and an inner surface of the first shell opposite to the display module.

9. The set according to claim 1 , wherein a surface of the back plate of the display module opposite to the first shell is provided with a plurality of support posts, and the plurality of support posts abut against an inner surface of the first shell opposite to the display module.

10. The set according to claim 1 , wherein a stepped portion is provided on the other end of the second shell away from the first shell in a region opposite to the system board, and the stepped portion is configured to escape an edge of the system board as well as an interface on the system board.

11. The set according to claim 10 , wherein the stepped portion comprises a first step surface lower than the other end of the second shell away from the first shell, and a second step surface lower than the first step surface,
wherein a distance is provided between the first step surface and a surface of the system board opposite to the first shell; and
the second step surface is lower than at least one interface on the system board.

12. The set according to claim 1 , wherein the first shell is provided with a recess portion recessed from an outer surface of the first shell facing away from the display module toward the display module; and
the recess portion is provided with a fixing portion and an interface portion.

13. The set according to claim 1 , wherein at least one of a USB interface, a power interface or a memory card interface is correspondingly disposed on the second shell and the bezel.

14. The set according to claim 1 , wherein an aspect ratio of a display region of a display panel of the display module is greater than or equal to 4:1.

15. The set according to claim 1 , wherein the display module comprises the back plate, a reflective sheet, a light guide plate, at least one functional film layer, a display panel, and a middle frame,
the reflective sheet, the light guide plate, the at least one functional film layer and the display panel are located on a side of the back plate away from the first shell, and sequentially arranged in a direction away from the back plate, and
the middle frame surrounds the reflective sheet, the light guide plate, the at least one functional film layer and the display panel;
wherein a backlight source is provided oppositely on a side of a light incident surface of the light guide plate.

16.
