WIPO Patent Application WO/2021/212632
Kind Code:
A1
Abstract:
Disclosed are a curved-surface screen protection film (100) and a curved-surface cover plate. The curved-surface screen protection film (100) comprises a planar area (100a) and at least one bent area (100b) located on the outer side of the planar area (100a); and when the curved-surface screen protection film (100) is in a flattened state, the portion of the curved-surface screen protection film (100) corresponding to the respective bent area (100b) is at least provided with a recess portion (101), so as to improve the bending performance of the curved-surface screen protection film (100), and solve the problems whereby when the curved-surface screen protection film (100) is attached to a curved-surface screen or a curved-surface cover plate, the edge of the curved-surface screen protection film (100) is prone to warping and bubbles are generated.
