Problems solved by technology
[0002] With the continuous development of technology, more and more curved display designs are used in display panels to increase the screen-to-body ratio of display panels, and special-shaped display panels and curved display panels have also begun to emerge. However, due to the curved edge of the display panel, traditional After the protective film is attached, within a certain period of time, the corners of the protective film will be warped, bubbles will be generated, and even the edges will fall off, which will cause the protective film to fail to protect the cover well.

Abstract
The invention discloses a curved screen protective film and a curved cover plate. The curved screen protection film comprises a plane area and at least one bending area located on the outer side of the plane area. When the curved screen protective film is in a flattened state, the part, corresponding to each bending area, of the curved screen protective film is provided with at least one concave part, so that the bending performance of the curved screen protective film is improved, and the problems that the edge of the curved screen protective film is prone to tilting and bubbles are generatedwhen the curved screen protective film is attached to a curved screen or a curved cover plate are solved.
Description
technical field [0001] The present application relates to the field of display technology, in particular to a curved screen protective film and a curved cover. Background technique [0002] With the continuous development of technology, more and more curved display designs are used in display panels to increase the screen-to-body ratio of display panels, and special-shaped display panels and curved display panels have also begun to emerge. However, due to the curved display edges, traditional After the protective film is attached, within a certain period of time, the corners of the protective film will be lifted, bubbles will be generated, and even the edges will fall off. As a result, the protective film cannot protect the cover well. Contents of the invention [0003] The embodiment of the present application provides a curved screen protective film and a curved cover plate, which can improve the problem that when the curved screen protective film is attached to the curv...
