1. A display module, comprising:
a display panel,
a middle frame,
a film assembly,
a backlight source, and
a backplane,
wherein the backplane seals an opening of a bottom of the middle frame;
both the film assembly and the backlight source are arranged in a containing cavity defined by the middle frame and the backplane;
the middle frame comprises:
a plurality of sub-frames connected in sequence end to end;
wherein each of the sub-frames comprises:
a body; and
a support portion arranged on the body;
wherein the support portion extends into the containing cavity to form a T-shaped structure with the body;
the support portion is provided with a support surface used for supporting the display panel; and
the display panel is arranged on the support surface;
the backplane comprises:
a substrate sealing the opening of the bottom of the middle frame; and
flanges formed at an edge of the substrate and located on an inner side of the middle frame;
wherein the flanges correspond to the sub-frames one to one;
the plurality of sub-frames of the middle frame comprise:
at least one first sub-frame;
wherein a protrusion extending into the containing cavity is formed on a portion of the body of each of the at least one first sub-frame facing away from the support surface;
a surface of the protrusion facing away from the support portion abuts against a surface of the corresponding flange facing the support portion; and
in a thickness direction of the flange, an orthographic projection of the protrusion on the substrate does not completely cover an orthographic projection of the corresponding flange on the substrate; and
the backlight source and the film assembly are sequentially arranged on the substrate; and
in the thickness direction of the flange, an expansion gap is reserved between the protrusion and the film assembly.
