Abstract

Disclosed is a waterproof substrate, including: two mounting surfaces disposed facing away from each other; and at least one waterproof protrusion provided on at least one of the two mounting surfaces and including: a protrusion body connected with the mounting surface, and one end of the protrusion body away from the waterproof substrate includes a connecting end surface; and at least two waterproof ribs, and each of the waterproof ribs is provided on the connecting end surface respectively and is gradually inclined outwardly in a direction away from the connecting end surface respectively.

First claim

What is claimed is:

1. A waterproof assembly, comprising:
a waterproof substrate comprising:
two mounting surfaces, wherein one of the two mounting surfaces is on an upper side of a seal and the other of the two mounting surfaces is on a bottom side of the seal; and
at least one waterproof protrusion protruded from at least one of the two mounting surfaces and comprising:
a protrusion body connected with the mounting surface on the upper side of the seal, one end of the protrusion body away from the waterproof substrate comprising a connecting end surface; and
at least two waterproof ribs, each of the waterproof ribs being protruded from the connecting end surface respectively and being gradually inclined outwardly in a direction away from the connecting end surface respectively;
at least one waterproof protrusion strip provided on at least one of the two mounting surfaces of the waterproof substrate, spaced apart from the protrusion body, and extending in the same direction as the protrusion body.

2. The waterproof assembly according to claim 1 , wherein the waterproof ribs are evenly distributed on the connecting end surface respectively; and the at least one waterproof protrusion strip cooperates with the at least one waterproof protrusion to form multiple waterproof defense lines.

3. A display screen, comprising a cabinet and a display module connected with the cabinet, an installation space being defined between the display module and the cabinet, wherein the display screen further comprises:
a waterproof assembly according to claim 1 ,
wherein:
the waterproof assembly is disposed in the installation space;
a mounting surface of the waterproof substrate facing the cabinet and a mounting surface of the waterproof substrate facing the display module comprises the at least one waterproof protrusion; and
at least one of the cabinet and the display module is abutted against the at least two waterproof ribs.

4. The display screen according to claim 3 , wherein:
the display module is abutted against the at least two waterproof ribs; and
the mounting surface of the waterproof substrate facing away from the at least one waterproof protrusion is abutted against the cabinet.

5. The display screen according to claim 3 , wherein:
the cabinet is abutted against the at least two waterproof ribs; and
the mounting surface of the waterproof substrate facing away from the at least one waterproof protrusion is abutted against the display module.

6. The display screen according to claim 3 , wherein:
the mounting surface of the waterproof substrate facing the cabinet and the mounting surface of the waterproof substrate facing the display module are respectively provided with the at least one waterproof protrusion;
the waterproof ribs provided on one mounting surface of the waterproof substrate is abutted against the display module; and
the waterproof ribs provided on the other mounting surface of the waterproof substrate is abutted against the cabinet.

7. The display screen according to claim 3 , wherein at least one of the cabinet and the display module defines an embedded slot, the waterproof assembly being embedded in the embedded slot.

8. The display screen according to claim 3 , wherein the display module comprises:
a data interface;
wherein:
the waterproof substrate is a ring-shaped structure and surrounds the data interface.

9. The display screen according to claim 3 , wherein:
a surface of the cabinet in contact with the at least one waterproof protrusion is defined as a first abutting surface;
a surface of the display module in contact with the at least one waterproof protrusion is defined as a second abutting surface; and
at least one of the first abutting surface and the second abutting surface is inclined with respect to the mounting surface.

10. The display screen according to claim 9 , wherein the first abutting surface and the second abutting surface are inclined with respect to the mounting surface respectively.

11. The display screen according to claim 3 , wherein the waterproof ribs are evenly distributed on the connecting end surface respectively.

12. The display screen according to claim 3 , wherein:
a distance between the two waterproof ribs gradually increases in the direction away from the connecting end surface.
