Problems solved by technology

The inventors of the present application found that the process of processing the support protrusions on the surface of the substrate is more complicated when implementing the scheme; The friction debris generated by board friction is easy to adhere to the surface of the substrate, which affects the packaging quality of the substrate and the product yield
In addition, for a flexible display panel, if the height of the supporting protrusion is too high, the packaging effect may be poor or the packaging may fail; if the height of the supporting protrusion is too short, the supporting effect may be poor
