CROSS-REFERENCE TO RELATED APPLICATION

The present application claims priority from Chinese patent application No. 201910918374.4 filed with China National Intellectual Property Administration (CNIPA) on Sep. 26, 2019, the disclosure of which is incorporated herein by reference.

TECHNICAL FIELD

The present disclosure relates to the field of display technologies, and particularly relates to a backplane, a frame structure and a display device.

BACKGROUND

Spliced frame structures are often adopted in various display devices nowadays. A spliced frame structure typically includes a backplane, a middle frame and a metal buckle via which the backplane and the middle frame are connected into a whole.

However, existing metal buckles are usually designed for easy mounting but not easy dismounting. As a result, the middle frame and the backplane connected into an integrated frame structure through an existing metal buckle are usually difficult to separate thereafter.

SUMMARY

The present disclosure provides a display substrate that, when the backplane needs to be separated from the middle frame, can separate a clamping member from a skirt of the backplane by applying an external force to a dismounting structure of the clamping member so that the separation of the middle frame and the backplane is completed.

The technical solution adopted to solve the technical problem of the present disclosure is a backplane secured to a middle frame in a display panel to form a frame structure of the display panel. The backplane includes a bottom plate and a skirt connected to edges of the bottom plate; wherein at least part of the skirt is provided with a clamping member for securing the backplane to the middle frame; and wherein the clamping member is provided with a dismounting structure for disengaging the clamping member from the skirt under an external force so that the backplane is separated from the middle frame.

In the above backplane provided by the present disclosure, since the dismounting structure is provided on the clamping member for connecting the middle frame to the backplane, when the backplane needs to be separated from the middle frame, the clamping member can be separated from the skirt of the backplane when an external force is applied to the dismounting structure of the clamping member, thereby accomplishing the separation of the middle frame and the backplane.

Optionally, in the above backplane provided by the present disclosure, the skirt of the backplane includes a first side surface and a second side surface extending along a length direction thereof and arranged oppositely; the clamping member includes a first side part and a second side part arranged oppositely, and an upper part connected between the first side part and the second side part; the first side part is provided with a clamping tongue structure, and the first side surface is provided with a groove; the second side part is provided with a clamping elastic sheet; and when the clamping member is clamped onto the skirt, the clamping tongue structure is engaged in the groove, and the clamping elastic sheet secures the backplane to the middle frame.

Optionally, in the above backplane provided by the present disclosure, the second side part has a plurality of clamping elastic sheets, and a connection part disconnected from the plurality of clamping elastic sheets and located between two adjacent clamping elastic sheets; wherein the plurality of clamping elastic sheets and the connection part are connected to the upper part; and the dismounting structure is located on a side of the connection part away from the second side surface.

Optionally, in the above backplane provided by the present disclosure, an inner width of the clamping member is greater than a thickness of the skirt, and a difference between the inner width of the clamping member and the thickness of the skirt is greater than an engagement depth of the clamping tongue structure in the groove; and the inner width of the clamping member is a distance between the first side part and the connection part in a direction perpendicular to the first side part.

Optionally, in the above backplane provided by the present disclosure, the connection part has a first hollowed-out portion; the first hollowed-out portion is provided with a buckle elastic sheet obliquely extending toward the first side part; and when the clamping member is clamped onto the skirt, the buckle elastic sheet is abutted against the second side surface of the skirt so that the clamping member is secured to the skirt.

Optionally, in the above backplane provided by the present disclosure, the dismounting structure includes a tab.

Optionally, in the above backplane provided by the present disclosure, the tab includes two tabs symmetrically disposed along a midline of the connection part in a direction parallel to the bottom plate.

Optionally, in the above backplane provided by the present disclosure, the first side part is provided with a second hollowed-out portion; the clamping tongue structure is disposed in the second hollowed-out portion, with one end closer to the bottom plate secured to a lower side of the second hollowed-out portion closer the bottom plate and the other end away from the bottom plate being movable.

Optionally, in the above backplane provided by the present disclosure, the material of the clamping member includes: spring steel.

Accordingly, the present disclosure further provides a frame structure including any one of the backplanes as described above, and a middle frame secured to the backplane.

Optionally, in the above frame structure provided by the present disclosure, the middle frame includes a side plate; the side plate includes a third side surface and a fourth side surface extending along a length thereof and arranged oppositely; the middle frame is sleeved outside the backplane, and the third side surface of the side plate is disposed opposite to the second side surface of the skirt; and the third side surface of the middle frame has a convex structure on which the clamping elastic sheet is clamped when the middle frame is secured to the backplane via the clamping member, so as to secure the relative position of the middle frame and the backplane.

Accordingly, the present disclosure further provides a display device including any one of the frame structures as described above.
