METHOD AND APPARATUS FOR DEPOSITING A FILM USING A ROTATING SOURCE

摘要

The disclosure generally relates to a method and apparatus for depositing a substantially solid film onto a substrate. The solid film can be an Organic Light- Emitting Diode ("OLED"). In one embodiment, the disclosure relates to using a material supply, a rotating or moving mechanism having at least one transfer surface which is supplied with film material in one orientation and delivers film material to the substrate at a second orientation such that film material delivered to the substrate deposits in substantially solid form. The delivery to the substrate can be performed without the transfer surface materially contacting the substrate. The film material can be deposited on the transfer surface in either solid form or in liquid form (e.g., as a mixture of carrier liquid and dissolved or suspended film material).
