METHOD FOR PRODUCING A LUMINOUS PIXEL ARRANGEMENT

The invention relates to a method for producing pixels which are applied on a substrate (4) and are luminous upon conducting electric current through them, wherein the pixels each comprise: an electron transport layer (ETL), a hole transport layer (HTL), a hole blocking layer (HBL) or an electron bl...

Beschreibung
Zusammenfassung:	The invention relates to a method for producing pixels which are applied on a substrate (4) and are luminous upon conducting electric current through them, wherein the pixels each comprise: an electron transport layer (ETL), a hole transport layer (HTL), a hole blocking layer (HBL) or an electron blocking layer (EBL) and a light-emitting layer (EML-R, EML-G, EML-B). The invention provides for thelayers (ETL, HTL, HBL, EBL, EML-R, EML-G, EML-B) each to be fabricated in a gas atmosphere with a total pressure of at least 0.001 mbar, wherein the total pressure is intended to be at least greater than 0.01 mbar. Light-emitting particles contained in a solvent can be used for depositing the light-emitting layer. The solvent can be vapor-deposited at a total pressure of < 10 mbar, in particular
