Claim Text:
1. A method of making a multi-color OLED device, including: a) applying a photo-patternable layer comprising a fluorinated photoresist material over a patterned first organic light-emitting layer in a substrate; b) selectively exposing at least a portion of the photo-patternable layer to a radiation; c) developing the photo-patternable layer with a fluorinated solvent to form a patterned layer; d) depositing a second organic light-emitting material over the substrate to form a second organic light-emitting layer; and e) applying the patterned fluorinated photoresist material to control the removal of a portion of the second organic light-emitting layer, the second organic light-emitting layer being deposited after forming the patterned fluorinated photoresist material, and the step of applying the patterned fluorinated photoresist material to control the removal of a portion of the second organic light-emitting layer comprising contacting the substrate with a second fluorinated solvent to remove the patterned fluorinated photoresist material and the portion of the second organic light-emitting layer such that a remaining portion of the second organic light-emitting layer is in electrical contact with a patterned electrode.
