Method for producing an organic electroluminescent display, and an organic electroluminescent display
A method for producing a display, in which a first electrode film is produced on a substrate, functional layers are then applied to this film, and a second electrode film is then produced on the functional layer. The first and/or second electrode film according to the invention is produced overall or structured on the substrate by means of a contact printing process.
1. Method for producing a display with the following process steps:
A) a first electrode film is produced on a substrate,
B) at least one functional layer is produced on the first electrode film,
C) a second electrode film is produced on the functional layer,
the first and/or second electrode film being produced overall on the substrate by means of a contact printing process, in which spacers are produced in a process step B1) prior to process step C) and/or B), and in which the spacers in process step C) prevent contact between the functional layer and a component of a printer responsible for transferring the second electrode film.
2. The method according to claim 1 in which the first and second electrode films are applied structured in the form of electrode strips and perpendicular to one another.
3. The method according to claim 1 in which organic electroluminescent materials are applied as the functional layer in process step B).
4. The method according to claim 1 in which the spacers ( 15 ) are structured as strip-shaped ridges in process step B1).
5. The method according to claim 1 , in which the face of the substrate ( 1 ) facing the observer is dulled in at least some areas.
6. The method according to claim 1 , wherein the spacers are structured as strip-shaped ridges in process step B1).
7. The method according to claim 1 , in which organic electroluminescent materials are applied as the functional layer in process step B).
8. Method for producing an OLED display with the following process steps:
