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.
