OLED screen, manufacturing method thereof and electronic device

The invention relates to an OLED screen, a manufacturing method thereof and an electronic device. The OLED screen comprises a cover plate, a substrate and an organic light emitting diode, wherein thecover plate and the substrate are oppositely arranged, and the organic light emitting diode is positioned between the cover plate and the substrate; the edge of the cover plate and the edge of the substrate are bonded in a sealed mode through sealant and a waterproof sealing frame; the waterproof sealing frame is positioned on the outer side of the sealant; a sealed cavity defined by the cover plate, the substrate and the sealant is filled with a liquid reinforcing layer; the reinforcing layer adsorbs the cover plate and the substrate; the liquid reinforcing layer is arranged in the OLED screen, the cover plate and the substrate are adsorbed into a whole; and when the OLED screen is impacted, the cover plate, the substrate and the reinforcing layer serve as a whole, the impact resistance is high, the reinforcing l
