Abstract:
A method is provided for forming a multi-color OLED device that includes providing a substrate, coating the substrate with a fluorinated photoresist solution to form a first photo-patternable layer and exposing it to produce a first pattern of exposed fluorinated photoresist material and a second pattern of unexposed fluorinated photoresist material, developing the photo-patternable layer with a fluorinated solvent to remove the second pattern of unexposed fluorinated photoresist material without removing the first pattern of exposed fluorinated photoresist material, depositing a first organic light-emitting material over the substrate to form a first organic light-emitting layer for emitting a first color of light and applying the first pattern of exposed fluorinated photoresist material to control the removal of a portion of the first organic light-emitting layer. A second fluorinated photoresist solution is then coated over the first patterned organic light-emitting layer and exposed to form a third pattern of exposed fluorinated photoresist material having a pattern different from the first pattern and a fourth pattern of unexposed fluorinated photoresist material, and developing the photo-patternable layer in a fluorinated solvent to remove the fourth pattern of unexposed fluorinated photoresist material without removing the third pattern of exposed fluorinated photoresist material, depositing at least a second light-emitting material to form a second light-emitting layer for emitting a second color of light that is different than the first color of light and applying the third pattern of exposed fluorinated photoresist material to control the removal of a portion of the second organic light-emitting layer.
