AI Technical Summary
Technical Problem
In the existing display modules, the double-sided EMI film edge design of the module FPC leads to increased stress and is prone to EMI interference problems.
Method used
The edges of both layers of EMI films are staggered wavy design, and the combination of wave portions of the front and reverse EMI films forms a circular edge, reducing edge overlap, reducing stress, and increasing the ability of the EMI film to cover the circuit.
Benefits of technology
It effectively reduces the double-sided EMI edge stress of the module FPC, while increasing the ability of EMI film to cover the line, reducing EMI interference problems.

Abstract
The utility model discloses a display module capable of reducing module FPC double-sided EMI edge stress, which comprises a module FPC, a front EMI film is attached to the front surface of the module FPC, a front boundary is formed at one end, close to a connector of the module FPC, of the front EMI film, and the front boundary comprises a front wave part and front edge parts connected with two ends of the front wave part, the front wave part comprises a plurality of semicircles connected in sequence, the opening directions of the adjacent semicircles are opposite, the front edge part of the front boundary and the back edge part of the back boundary coincide in the orthographic projection state, and the semicircle of the front wave part and the corresponding semicircle of the back wave part are combined to form a circle. The beneficial effects of the utility model lie in that the edges of the two layers of EMI films adopt the staggered wave-shaped design, so that the stress is reduced, the lines can be covered as much as possible, and the EMI interference problem is reduced.
