Double-sided display device, double-sided backlight module and frame structure

Abstract

This case discloses a frame structure suitable for a double-sided display device, comprising a middle layer, a first plate, and a second plate. The first plate includes a first main board and a first side plate. The first main board is riveted and fastened to the middle layer. The first side plate extends from the side of the first main board in a first direction. The first side plate and the first main board together define a first accommodating space. The second plate includes a second main board and a second side plate. The second main board is riveted and fastened to the middle layer. The second side plate extends from the side of the second main board in a second direction. The second direction is opposite to the first direction. The second side plate and the second main board together define a second accommodating space. The hardness of the middle layer is greater than the hardness of the first plate and the hardness of the second plate, or the thickness of the middle layer is greater than the thickness of the first plate and the thickness of the second plate.

The hardness of the middle layer is greater than the hardness of the first layer and the hardness of the second layer, or the thickness of the middle layer is greater than the thickness of the first layer and the thickness of the second layer.

2. The frame structure as described in claim 1, wherein the middle layer includes a third side panel extending from one side of the middle layer in the first direction, wherein the third side panel, the first side panel, and the first main board together define the first accommodating space.

3. The frame structure as described in claim 2, wherein the first plate includes a plurality of first side plates, each formed by a plurality of sides of the first main plate extending toward the first direction, wherein the third side plate, the first side plates, and the first main plate together define the first accommodating space.

4. The frame structure as described in claim 1, wherein the middle layer includes a fourth side panel extending from one side of the middle layer in the second direction, wherein the fourth side panel, the second side panel, and the second main board together define the second accommodating space.

5. The frame structure as described in claim 4, wherein the second plate includes a plurality of second side plates, each formed by a plurality of sides of the second main plate extending in the second direction, wherein the fourth side plate, the second side plates, and the second main plate together define the second accommodating space.

6. The frame structure as described in claim 1, wherein the first motherboard further includes a plurality of first through holes, the positions of the plurality of first through holes corresponding to the plurality of second riveting structures of the second motherboard, wherein the second motherboard includes a plurality of second through holes, the positions of the plurality of second through holes corresponding to the plurality of first riveting structures of the first motherboard, wherein the diameter of each first through hole is greater than the diameter of each second through hole, and the diameter of each second through hole is greater than the diameter of each first through hole.

7. The frame structure as described in claim 1, wherein the first motherboard further includes a first open portion, at least some of the plurality of second riveting structures of the second motherboard are exposed in the first open portion of the first motherboard, wherein the second motherboard further includes a second open portion, at least some of the plurality of first riveting structures of the first motherboard are exposed in the second open portion of the second motherboard.

8. The frame structure as described in claim 1, wherein the middle layer plate is a stepped plate structure and has two opposing surfaces, wherein one surface of the middle layer plate is recessed to form a first recess, and the first main plate is disposed in the first recess, and the other surface of the middle layer plate is recessed to form a second recess, and the second main plate is disposed in the second recess.

9. The frame structure as described in claim 8, wherein the first recess and the second recess are offset from each other.

10. The frame structure as described in claim 6, wherein the first main board of the first board and the plurality of second riveting structures of the second board are misaligned, wherein the second main board of the second board and the plurality of first riveting structures of the first board are misaligned.

11. A dual-sided backlight module structure, comprising: a frame structure as described in any one of claims 1 to 10; a first backlight module disposed in the first accommodating space of the frame structure; and a second backlight module disposed in the second accommodating space of the frame structure.

12. A double-sided display device, comprising: a double-sided backlight module structure as described in claim 11; a first display unit located in front of the first backlight module; and a second display unit located in front of the second backlight module.
