Abstract

A display device includes a double-sided display module. The double-sided display module includes first and second display modules arranged back to back and connectors. Each connector includes at least one first connection hole and at least one second connection hole. The first display module includes first connection portions. The second display module includes second connection portions; and positions of the connectors, the first connection portions and the second connection portions are in one-to-one correspondence; the first display module and the second display module are fixedly connected to the connectors through the first connection portions and the second connection portions; and each first connection portion is connected to a connector through one of a first connection hole and a second connection hole of the connector, and each second connection portion is connected to the connector through another of a first connection hole and a second connection hole of the connector.

First claim

What is claimed is:

1 . A display device, having at least one active area, comprising:
a display module; wherein the display module is a double-sided display module; and the double-sided display module includes:
a first display module and a second display module that are arranged back to back, wherein the first display module includes a first display panel, and the second display module includes a second display panel; and
a plurality of connectors, each connector including at least one first connection hole and at least one second connection hole; wherein
the first display module further includes a plurality of first connection portions, and the second display module further includes a plurality of second connection portions; and positions of the plurality of connectors, the plurality of first connection portions and the plurality of second connection portions are in one-to-one correspondence;
the first display module and the second display module are fixedly connected to the plurality of connectors through the plurality of first connection portions and the plurality of second connection portions; and
each first connection portion is connected to a connector through one of a first connection hole and a second connection hole of the connector, and each second connection portion is connected to the connector through another of a first connection hole and a second connection hole of the connector.

2 . The display device according to claim 1 , further comprising: an encapsulation housing disposed on a periphery of the first display module and the second display module, the encapsulation housing being configured to fix the first display module and the second display module; wherein
the encapsulation housing includes side walls opposite to side faces of the first display panel and the second display panel, and the encapsulation housing further includes a plurality of third connection portions disposed on the side walls in a thickness direction of the double-sided display module; positions of the plurality of connectors and the plurality of third connection portions are in one-to-one correspondence; the encapsulation housing is fixedly connected to the plurality of connectors through the plurality of third connection portions; each connector further includes at least one third connection hole; and each third connection portion is connected to a connector through a third connection hole of the connector.

3 . The display device according to claim 2 , wherein
a number of the plurality of first connection portions is the same as a number of the plurality of second connection portions; and the plurality of first connection portions and the plurality of second connection portions are disposed on two opposite sides of the first display module and the second display module, respectively.

4 . The display device according to claim 3 , wherein the first connection portion and the second connection portion are each a connection piece, the connection piece has at least one through hole extending in a direction same as the thickness direction of the double-sided display module, and each connection piece is connected to a first connection hole or a second connection hole in a corresponding connector through a first screw; and
the third connection portion is a through hole disposed in a side wall of the encapsulation housing and extending in the thickness direction of the double-sided display module; and the third connection portion is connected to a third connection hole in a corresponding connector through a second screw.

5 . The display device according to claim 4 , wherein the encapsulation housing further includes a first housing and a second housing;
in the thickness direction of the double-sided display module and in a direction perpendicular to one side of the double-sided display module, sections of the first housing and the second housing are both L-shaped; and a side wall of the first housing and a side wall of the second housing overlap at side faces of the first display module and the second display module; and overlapping side walls of the first housing and the second housing are each provided with a sub-through hole, and two sub-through holes corresponding in positions overlap to form a third connection portion.

6 . The display device according to claim 2 , wherein each connector further includes: a first surface and a second surface disposed opposite to each other, and a third surface and a fourth surface that are both connected to the first surface and the second surface and are disposed opposite to each other;
the connector is disposed on a side of a side wall of the encapsulation housing proximate to the first display panel and the second display panel, and the fourth surface of the connector is closer to the first display panel and the second display panel than the third surface; and the first connection hole is disposed in the first surface and extends toward the second surface, the second connection hole is disposed in the second surface and extends toward the first surface, and the third connection hole is disposed in the third surface and extends toward the fourth surface.

7 . The display device according to claim 6 , wherein a vertical distance from an axis of the second connection hole to the fourth surface is greater than a vertical distance from an axis of the first connection hole to the fourth surface.

8 . The display device according to claim 6 , wherein in a direction pointing from the fourth surface to the third surface, a thickness of the connector increases stepwise, and the thickness of the connector refers to a dimension of the connector in a direction pointing from the second surface to the first surface.

9 . The display device according to claim 8 , wherein the connector includes a fourth connection portion and a fifth connection portion that are sequentially arranged in the direction pointing from the fourth surface to the third surface;
the fourth connection portion and the fifth connection portion are of an integral structure, a side face of the fourth connection portion away from the fifth connection portion is the fourth surface, and a side face of the fifth connection portion away from the fourth connection portion is the third surface; a thickness of the fifth connection portion is greater than a thickness of the fourth connection portion; a portion of the first surface corresponding to the fourth connection portion is retracted toward the second surface relative to a portion of the first surface corresponding to the fifth connection portion; and a portion of the second surface corresponding to the fourth connection portion is retracted toward the first surface relative to a portion of the second surface corresponding to the fifth connection portion; and the at least one first connection hole and the at least one second connection hole are both disposed in the fourth connection portion.

10 . The display device according to claim 8 , wherein the connector includes a sixth connection portion, a seventh connection portion and an eighth connection portion that are sequentially arranged in the direction pointing from the fourth surface to the third surface;
