Display Module, Method for Manufacturing Display Module, and Display Apparatus

A method for manufacturing a display module, comprising:

• providing a display panel, the display panel comprising a display portion, a bending portion and a bonding portion that are connected to each other in sequence, and bending the bending portion to enable the bonding portion to be located on a non-display side of the display portion;
• providing a cover plate on a display side of the display portion in a stack, wherein than a boundary of the bending portion farthest from the display portion, a boundary, at a same side as the boundary of the bending portion, of the cover plate is farther away from the display portion;
• and
• forming a first frame on a side of the cover plate proximate to the display panel, the first frame extending along a side edge of the cover plate corresponding to the bonding portion;
• wherein forming the first frame comprises:
• forming a first retaining wall on an edge region of the cover plate by a printing process;
• forming a second retaining wall on a side of the bonding portion away from the cover plate by a printing process, the second retaining wall and the first retaining wall having a spacing therebetween;
• and
• forming a first filling portion between the first retaining wall and the second retaining wall by a printing process or an adhesive pouring process;
• wherein a viscosity of a material for forming the first retaining wall and a viscosity of a material for forming the second retaining wall are greater than a viscosity of a material for forming the first filling portion.
