Abstract: An organic light-emitting display panel, a method of forming the same and a display device are provided. The method of forming an organic light-emitting display panel includes: providing a base substrate; forming an auxiliary cathode at a side of the base substrate and forming a pixel defining layer at a side of the auxiliary cathode away from the base substrate; filling a negative thermal expandable ball into the groove; forming a light-emitting layer at the side of the base substrate; performing a heating treatment and a vibrating treatment on the base substrate with the light-emitting layer; and forming a cathode layer at a side of the light-emitting layer away from the base substrate.

Abstract: The present disclosure provides an evaporation device and an evaporation method. The evaporation device includes: an evaporation chamber; a plurality of spaced conductive baffles disposed in the evaporation chamber and dividing the evaporation chamber into a plurality of evaporation sub-chambers, the conductive baffles configured to carry charges of a first polarity; an evaporation source disposed in at least one of the evaporation sub-chambers; and a particle charging circuit disposed in at least one of the evaporation sub-chambers. The particle charging circuit is configured to control evaporation material particles generated from the evaporation source in at least one of the evaporation sub-chambers to have charges of the first polarity.
