Method for forming an organic element of an electronic device

A method for forming an organic element of an electronic device having at least two different pixel types including a first pixel type (pixel A) and a second pixel type (pixel B),

• wherein at least one layer of pixel A is deposited by applying an ink A containing at least one organic functional material A and at least one solvent A by a printing process,
• wherein at least one layer of pixel B is deposited by applying an ink B containing at least one organic functional material B and at least one solvent B by a printing process,
• wherein at least one organic functional material A and at least one organic functional material B are different, and
• wherein at least one solvent A and at least one solvent B are different,
• characterized in that both inks, ink A and ink B, in addition contain at least one common solvent S, and
• characterized in that the boiling point of solvent A and the boiling point of solvent B is at least 10° C. lower than the boiling point of the common solvent S.

Kit of inks comprising at least two different inks,

• an ink A containing at least one organic functional material A and at least one solvent A, and
• an ink B containing at least one organic functional material B and at least one solvent B,
• wherein at least one organic functional material A and at least one organic functional material B are different, and
• wherein at least one solvent A and at least one solvent B are different,
• characterized in that both inks, ink A and ink B, in addition contain at least one common solvent S, and
• characterized in that the boiling point of solvent A and the boiling point of solvent B is at least 10° C. lower than the boiling point of the common solvent S.
