The application provides a sound insulation and heat preservation integrated prefabricated laminated board and a laminated board system, and belongs to the field of fabricated buildings. The laminated board comprises a prefabricated part, a heat insulation and sound insulation layer and a laminated layer. The prefabricated part comprises a prefabricated bottom plate and a connecting piece, the connecting piece is arranged on the prefabricated bottom plate, the heat insulation and sound insulation layer is continuously formed on the prefabricated bottom plate, the laminated layer is formed on the heat insulation and sound insulation layer, the connecting piece penetrates through the heat insulation and sound insulation layer, the bottom of the connecting piece is connected to the prefabricated bottom plate, the top of the connecting piece extends into the laminated layer, a first protective layer is formed between the top of the connecting piece and the top surface of the laminated layer, and a second protective layer is formed between the bottom of the connecting piece and the bottom surface of the prefabricated bottom plate. The heat insulation and sound insulation layer is arranged in the middle of the laminated board, a sandwich form is formed, a complete and continuous heat insulation and sound insulation layer is formed in the laminated board, and floor surface layer cracking caused by on-site laying of the heat insulation and sound insulation layer can be effectively avoided.

The display panel and the display module are provided. The display panel comprises a substrate, a light emitting unit, a first electrode and an isolation structure. The isolation structure is arranged on one side of the substrate and encloses a plurality of isolation openings. The light emitting unit is at least partially located in the isolation opening. The first electrode covers the light emitting unit and comprises a main body and a thinning portion. The main body covers a central area of the isolation opening and extends outward to form the thinning portion. At least part of the thinning portion is electrically connected to the isolation structure. The thickness of the thinning portion is less than the thickness of the main body. By controlling the topography of the first electrode, effective lapping with the isolation structure is achieved while the lapping resistance is reduced, and subsequent display abnormalities can be reduced.
