OLED screen and manufacturing method thereof, and electronic device

The invention relates to an OLED screen and a manufacturing method thereof, and an electronic device. The OLED screen comprises a cover plate and a substrate, which are oppositely arranged, and an organic light emitting diode, a waterproof sealing frame and a solid hot melt adhesive layer, which are arranged between the cover plate and the substrate, wherein the waterproof sealing frame is connected between the edge of the cover plate and the edge of the substrate, the organic light emitting diode is located in an area surrounded by the cover plate, the substrate and the waterproof sealing frame, and the area surrounded by the cover plate, the substrate and the waterproof sealing frame is filled with the hot melt adhesive layer. The solid hot melt adhesive layer is arranged in the OLED screen to adsorb the cover plate and the substrate into an entirety, when the OLED screen is impacted, the cover plate, the substrate and the hot melt adhesive layer is as an entirety, which has high impact resistance, and furt
