Abstract

Disclosed are a bezel display device and manufacturing method thereof are provided, where the bezel is a 90-degree bezel without a gap at a front surface, which is formed by an aluminum extruded profile with an inverted F-shaped cross-section which is softened under a high temperature and bent by using a bending mold. The method includes: softening an aluminum extruded profile with an inverted F-shaped cross-section under a high temperature; and bending the aluminum extruded profile using a bending mold to form a 90-degree bezel without a gap at a front surface.

First claim

What is claimed is:

1 . A bezel of a display device, the bezel being used to fix a display module of the display device, wherein
the bezel is a 90-degree bezel without a gap at a front surface, which is formed by an aluminum extruded profile with an inverted F-shaped cross-section which is softened under a high temperature and bent by using a bending mold.

2 . The bezel according to claim 1 , wherein a crack arrest groove is a slotted at a rear of the aluminum extruded profile.

3 . The bezel according to claim 2 , wherein the bending mold bends the aluminum extruded profile from 180 degrees to 90 degrees through N bending angles in order, the N bending angles being less than 180 degrees and greater than 90 degrees.

4 . The bezel according to claim 3 , wherein the N is two, and the bending angles comprise a first bending angle and a second bending angle.

5 . The bezel according to claim 4 , wherein the first bending angle is 150 degrees, and the second bending angle is 120 degrees.

6 . A display device, comprising a bezel and a display module, and the bezel being used to fix the display module, wherein
the bezel is a 90-degree bezel without a gap at a front surface, which is formed by an aluminum extruded profile with an inverted F-shaped cross-section which is softened under a high temperature and bent by using a bending mold.

7 . The display device according to claim 6 , wherein a crack arrest groove is a slotted at a rear of the aluminum extruded profile.

8 . The display device according to claim 7 , wherein the bending mold bends the aluminum extruded profile from 180 degrees to 90 degrees through N bending angles in order, the N bending angles being less than 180 degrees and greater than 90 degrees.

9 . The display device according to claim 8 , wherein the N is two, and the bending angles comprise a first bending angle and a second bending angle.

10 . The display device according to claim 9 , wherein the first bending angle is 150 degrees, and the second bending angle is 120 degrees.

11 . A method for manufacturing a bezel of a display device, the bezel being used to fix a display module of the display device, comprising
softening an aluminum extruded profile with an inverted F-shaped cross-section under a high temperature; and bending the aluminum extruded profile using a bending mold to form a 90-degree bezel without a gap at a front surface.

12 . The manufacturing method according to claim 11 , wherein upon the softening an aluminum extruded profile under a high temperature, the method further comprises:
slotting a crack arrest groove on a rear of the aluminum extruded profile.

13 . The manufacturing method according to claim 12 , wherein the bending the aluminum extruded profile with an inverted F-shaped cross-section using a bending mold to form a 90-degree bezel without a gap at a front surface comprises: bending, by the bending mold, the aluminum extruded profile from 180 degrees to 90 degrees through N bending angles in order, the N bending angles being less than 180 degrees and greater than 90 degrees.

14 . The manufacturing method according to claim 13 , wherein the N is two, and the bending angles comprise a first bending angle and a second bending angle.

15 . The manufacturing method according to claim 14 , wherein the first bending angle is 150 degrees, and the second bending angle is 120 degrees.
