Abstract
Embodiments of the present invention provide a display module and a display device. The display module includes a substrate, a light-emitting layer, and a cover plate, and the cover plate includes a hard layer and a protective layer. A surface hardness of the hard layer is greater than a surface hardness of the protective layer, and a thickness of the protective layer is less than or equal to 50 um. When a stylus is used to touch the flexible panel, the hard layer can prevent scratches from forming on a surface of the hard layer, and meanwhile, the display module has better bending performance, thereby improving the overall performance of the flexible display device.
Claims20
A display module, comprising:
- a substrate;
- a light-emitting layer disposed on a side of the substrate;
- and
