Abstract

An electronic device is provided, including a curved backlight module, a display module, a fixing member, and a glue. The curved backlight module includes a curved back plate. The display module is disposed on the curved backlight module. The fixing member is disposed between the curved backlight module and the display module. The glue adheres the fixing member and the display module, and the fixing member is configured to affix the display module to the curved back plate.

First claim

What is claimed is:

1 . An electronic device, comprising:
a curved backlight module, comprising a curved back plate; a display module, disposed on the curved backlight module and comprising an inner surface facing the curved backlight module; a fixing member, comprising at least one protruding portion that is in contact with the inner surface; a glue, adhering the fixing member to the display module, wherein the fixing member is configured to affix the display module to the curved back plate, wherein the fixing member comprises a plurality of fixing portions configured to affix the fixing member to the curved back plate, wherein the fixing member comprises a first side and a second side, a curvature of the first side is greater than a curvature of the second side, the plurality of the fixing portions are disposed on the first side and the second side respectively, and a density of the fixing portions on the first side is greater than a density of the fixing portions on the second side.

2 . The electronic device as claimed in claim 1 , further comprising a plurality of locking members, wherein the plurality of locking members pass through the fixing portions and connect to the curved back plate.

3 . The electronic device as claimed in claim 1 , wherein a plurality of first latch mechanisms are formed on the curved back plate, each of the fixing portions has a second latch mechanism, and the first latch mechanisms and the second latch mechanisms are engaged with each other.

4 . The electronic device as claimed in claim 1 , wherein the electronic device further comprises a plurality of locking members, the fixing portions on the first side are affixed to the curved back plate via the locking members, wherein a plurality of first latch mechanisms are formed on the curved back plate, each of the fixing portions on the second side has a second latch mechanism, and the fixing portions on the second side are affixed to the curved back plate via the first latch mechanisms and the second latch mechanisms.

5 . The electronic device as claimed in claim 1 , further comprising a plurality of locking members, wherein each of the fixing portions has a through hole corresponding to one of the locking members and a second latch mechanism corresponding to a first latch mechanism on the curved back plate.

6 . The electronic device as claimed in claim 1 , wherein a height of the protruding portion is greater than or equal to a height of the glue.

7 . The electronic device as claimed in claim 1 , wherein the display module comprises a cover plate and a display panel, a gap is formed between an edge of the display panel and an edge of the cover plate, and the glue adheres the cover plate inside the gap.

8 . The electronic device as claimed in claim 7 , wherein the glue and the fixing member are accommodated in the gap.

9 . The electronic device as claimed in claim 7 , wherein the display module further comprises an adhesive member disposed between the cover plate and the display panel, and a width of the adhesive member is less than a width of the cover plate.

10 . The electronic device as claimed in claim 1 , further comprising a plurality of fixing members, wherein each of the fixing members has a L-shaped structure.

11 . The electronic device as claimed in claim 1 , further comprising a plurality of fixing members, wherein each of the fixing members has a longitudinal structure.

12 . The electronic device as claimed in claim 1 , further comprising a plurality of fixing members, wherein one of the fixing members has a C-shaped structure, and another one of the fixing members has a longitudinal structure.

13 . The electronic device as claimed in claim 1 , wherein the fixing member comprises a first side, a second side, a fourth side, an extending section, and an additional extending section, the second side and the fourth side are connected to opposite ends of the first side, the extending section is connected to the second side and extends toward the fourth side, and the additional extending section is connected to the fourth side and extends toward the second side, wherein a gap is formed between the extending section and the additional extending section.

14 . The electronic device as claimed in claim 13 , wherein a circuit board of the curved backlight module or a circuit board of the display module is accommodated in the gap and separated from the extending section and the additional extending section.

15 . The electronic device as claimed in claim 13 , wherein a connecting portion between the first side and the second side includes an arc structure, and a connecting portion between the first side and the fourth side includes an arc structure.

16 . A manufacturing method of an electronic device, comprising:
providing a curved backlight module, wherein the curved backlight module comprises a curved back plate with a first curvature; providing a fixing member comprising at least one protruding portion; and disposing a display module with a second curvature on the curved back plate by using the fixing member, wherein the first curvature is greater than the second curvature,
wherein the fixing member comprises a plurality of fixing portions configured to affix the fixing member to the curved back plate,
wherein the display module comprises an inner surface facing the curved backlight module, and the protruding portion is in contact with the inner surface,
wherein the fixing member comprises a first side and a second side, a curvature of the first side is greater than a curvature of the second side, the plurality of the fixing portions are disposed on the first side and the second side respectively, and a density of the fixing portions on the first side is greater than a density of the fixing portions on the second side.

17 . The manufacturing method as claimed in claim 16 , wherein the step of disposing a display module with a second curvature on the curved back plate by using the fixing member comprises:
providing a glue; coating the glue on the display module; pressing the fixing member onto the glue to adhere the fixing member to the display module; and affixing the fixing member to the curved back plate.

18 . The manufacturing method as claimed in claim 16 , wherein the step of disposing a display module with a second curvature on the curved back plate by using the fixing member comprises:
providing a glue; coating the glue on the fixing member; pressing the fixing member with the glue onto the display module to adhere the fixing member to the display module; and affixing the fixing member to the curved back plate.
