Electronic paper display module

An electronic paper display module, comprising an array substrate and an electronic paper film arranged opposite to each other, wherein

• the electronic paper film comprises a common electrode;
• the array substrate comprises a display region and a peripheral region, and a common electrode lead is located at the peripheral region;
• and
• an orthogonal projection of the electronic paper film onto the array substrate at least covers the display region, and the common electrode lead is provided with a hollowed-out region;
• wherein the array substrate further comprises a base substrate, the base substrate comprises a buffer layer and an insulation layer laminated one on another, the common electrode lead is located at a side of the insulation layer away from the buffer layer, and the insulation layer is arranged at a side of the common electrode lead away from the electronic paper film;
• the buffer layer is provided with a concave-convex region at a side close to the insulation layer, each concave is depressed in a direction away from the common electrode lead, and each convex is protruded in a direction close to the common electrode lead;
• and
• at least a part of the insulation layer and at least a part of the common electrode lead are deformed along with the concave-convex region of the buffer layer so as to form the hollowed-out region of the common electrode lead.
