A method is described for large-area application of at least two, for example, electroluminescent layers onto a substrate. In a process step A), spacer () is structured on the transparent substrate in such a way that, upon application of a second functional layer (), contact between a first functional layer () already applied on the substrate and a part of a printing machine responsible for the transfer of the functional layers onto the substrate is avoided. In two other process steps B) and C), the first functional layer () and the second functional layer () are applied over a large area, for example, through large-area standard printing methods.

Method for applying mechanically sensitive layers to a substrate over a large area

The invention describes a passive-matrix powered display with structured pixels and a structured second electrode based on electroluminescent polymers with the following characteristics: functional polymer coatings, which contact a first electrode, are enclosed by windows of an insulating window coating, at least one additional insulating striped coating, which is located between the windows of the first insulating coating, is located across from the first electrode strips as a partition, a second electrode that contacts the functional coatings is structured through partitions and runs across toward the first electrode strips between the partitions.

Organic electroluminescent device and the production thereof

The invention relates to a passive matrix-driven display based on electroluminescent polymers having a structured matrix of pixels and a structured second electrode with electrode connectors, having the following features: the functional polymers are delimited by windows of an insulating layer and contact a first electrode structured in the shape of strips and a second electrode, running parallel to the first electrode and also strip-shaped, which is in contact with electrode connectors; additional windows are disposed in the insulating layer and are positioned over the electrode connectors for the second electrode, or areas of the insulating layer are disposed between the electrode connectors; an encapsulation is provided that covers the insulating layer with the functional polymers and the second electrode, but leaves one end of each electrode connector exposed.

Organic, electroluminescent display and method for producing the same

Devices and method for continuous printing of organic light-emitting diodes (OLEDs) are described. A substrate with or without coating is provided as strip material on a roll, and is fed through a device with movable screens for imprinting by screen printing.

Device and method for continuous screen printing of organic light emitting diodes

Apparatus and procedure for the in situ measurement of quantities of polymer printed onto supports A source of radiationsends electromagnetic radiation onto a dropletof polymer solution or polymer dispersion, which is printed onto a support. A detectormeasures the transmitted or re-emitted radiation. Controlled by a comparator deviceand a control unit, the printing parameters are corrected in situ, if necessary. In this manner, a controlled adjustment of the layer thickness of organic light-emitting diodes and therefore luminosity and color perception can be achieved.

The present invention relates to an organic, colored, electroluminescent display having the following features:

Organic, colored, electroluminescent display and the production thereof

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.
