Title:
ELECTROMAGNETIC SHIELDING FILM, FLEXIBLE CIRCUIT BOARD, AND DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/040968
Kind Code:
A1
Abstract:
An electromagnetic shielding film, a flexible circuit board, and a display device. The electromagnetic shielding film comprises a central portion (10) and an edge portion (11, 12); the central portion (10) has several side edges (101, 102) provided on the periphery; the edge portion (11, 12) is provided on at least one side edge of the central portion (10); the edge portion (11, 12) comprises a plurality of protruding units (110, 120) protruding in a direction away from the central portion (10); the plurality of protruding units (110, 120) are arranged along an extending direction of the side edge where the edge portion (11, 12) is located. The electromagnetic shielding film is adapted to be attached onto a flexible circuit board body, and the central portion is at a non-bending area of the flexible circuit board body and the edge portion is at a bending area of the flexible circuit board body, so as to form the flexible circuit board. The edge portion of the electromagnetic shielding film can reduce stress generated by the bending area of the flexible circuit board body, such that the flexible circuit board consisting of the electromagnetic shielding film and the flexible circuit board body has good bending performance.
