Base plate preform, display module preform and methods for manufacturing base plate preform and display module preform

A display module, comprising a display area and a bonding area, the display module further comprising a base plate comprising a substrate, a metal layer and a third organic layer, the metal layer being provided with a bonding pad in the bonding area, the third organic layer covering the display area, and an orthographic projection of the third organic layer on the substrate not overlapping with an orthographic projection of the bonding pad on the substrate.

A method for manufacturing a base plate preform, the base plate preform comprising a bonding area and a functional area, the method comprising:

• providing a substrate;
• forming a metal layer on a side of the substrate, the metal layer comprising a metal wiring located in the functional area and a bonding pad located in the bonding area;
• forming a first organic layer on a side of the metal layer away from the substrate, the first organic layer covering the metal wiring and at least a sidewall of the bonding pad.
