Insert mold, display module, and display device and method for manufacturing the same

A display module, attached to a plastic frame through an insert mold and comprising:

• a display portion;
• a cover plate provided on a side of the display portion;
• a composite functional layer provided on a side of the display portion facing away from the cover plate;
• an adhesion-reducing layer provided on a side of the composite functional layer away from the display portion and having adhesion smaller than adhesion of at least one layer of the composite functional layer,
• wherein the insert mold comprises:
• a first mold comprising a first mold core and a first mold base provided outside the first mold core, the first mold core having a first surface and a second surface opposite to each other in a first direction, the first surface being configured to be in contact with the display module, the first mold core comprising an injection channel, a cavity, and a fixing structure, the injection channel and the cavity being recessed from the first surface and separated from each other, the cavity being configured to form a dam structure through injection, and the fixing structure being configured to be in contact with the dam structure so that the insert mold is configured to take the dam structure away from the display module through the fixing structure.

A display module, comprising:

• a display portion;
• a cover plate provided on a side of the display portion;
• a binding portion provided on a side of the display portion away from the cover plate;
• a protective layer provided on a side of the binding portion away from the display portion, the binding portion extending beyond the protective layer in a third direction to form a step structure, and a thickness direction of the display portion intersecting with the third direction;
• an adhesive layer partially provided between the binding portion and the protective layer, a part of the adhesive layer being attached to the step structure.
