A porous graphene film, its manufacturing method and an electronic product are provided. The method of manufacturing the porous graphene film includes: mixing a dispersion liquid of graphene with a dispersion liquid of particles, and performing a film-forming process to form a mixed film of graphene and particles; and removing the particles in the mixed film of graphene and particles to form the porous graphene film. The porous graphene film prepared by the method has a large specific surface area and an excellent electroconductivity.

Porous graphene film, its manufacturing method and electronic product

An organic light-emitting diode device and a manufacturing method thereof, a display substrate, and a display device are provided. The organic light-emitting diode device includes an anode layer, an organic light-emitting layer and a cathode layer which are stacked. The organic light-emitting diode device further includes a self-repairing layer, and the self-repairing layer is arranged on a side of the cathode layer away from the anode layer, and the self-repairing layer is applicable for repairing the cathode layer by an oxidation-reduction reaction.
