1. A backlight module, comprising:
a backplane, comprising:
a bottom plate, and
a plurality of side plates connected with an edge of the bottom plate,
wherein the plurality of side plates and the bottom plate match to define an accommodating space, the plurality of side plates comprise at least one first side plate, and the first side plate is provided with at least two clamping grooves distributed in an extending direction of the first side plate; and
an adhesive frame, comprising:
a plurality of subframes connected with the plurality of side plates in a one-to-one correspondence mode,
wherein a first subframe in the plurality of subframes is connected with the first side plate, the first subframe comprises:
a bearing part, and
at least two clamping parts in one-to-one correspondence with the clamping grooves,
wherein the bearing part is located on a side of the accommodating space away from the bottom plate, the at least two clamping parts are located on a side of the bearing part facing the bottom plate, and the clamping parts each is clamped with a corresponding one of the clamping grooves in a matching mode and is completely embedded into the corresponding one of the clamping grooves;
a thickness of the first side plate in a first direction is greater than a thickness of the clamping part connected with the first side plate in the first direction, wherein the first direction is perpendicular to an extending plane of the first side plate.
