摘要:
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 (5) is structured on the transparent substrate in such a way that, upon application of a second functional layer (11), contact between a first functional layer (10) 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 (10) and the second functional layer (15) are applied over a large area, for example, through large-area standard printing methods.

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.

A substrate with banks having end channels is provided to advantageously allow excess fluid collecting on one part of the substrate to flow to another part of the substrate. An excess of fluid collecting in a particular area of the substrate may flow to an area of the substrate where it would not interfere with the manufacturing process. The end channels may be modified with wave breakers that act as buffers to redirect excess fluid and/or with capillary-force homogeneity enhancers that pull excess fluid away from other parts of the substrate. The end channels may also contain line-end reservoirs that provide additional room for excess fluid to collect.

Systems and methods are described for delivering droplets. One embodiment provides a system comprising nozzles adapted to deliver droplets to target points on the substrate, a first camera, and means for determining an angular rotation of the substrate in a coordinate system. In some embodiments the means for determining the angular rotation includes a second camera. The substrate has a top surface and alignment marks. The nozzles have droplet delivery openings oriented towards the substrate for delivery of the droplets. The first camera is oriented substantially towards the nozzle openings, and the second camera is oriented substantially towards the substrate top surface.

Poly-siloxane material may be used to form an insulating structure in an organic light-emitting device (OLED). In addition to the insulating structure, an OLED may have an electro-luminescent organic layer separated into light-emitting elements, e.g., display pixels, arranged between electrode layers. A voltage applied across the electrode layers causes the device to emit light. One type of insulating structure may be a bank structure formed from a thin sheet of poly-siloxane with apertures corresponding to the display pixels. Pixels may be formed with the deposit of one or more layers of organic material into the apertures. Another type of insulating structure may be one or more insulating strips, which may separate an electrode layer into electrode strips during construction and/or insulate electrode strips while the OLED is in operation.

A system and method is presented for measuring the volume of an ink-jet droplet or the relative volumes of a plurality of ink-jet droplets using their electrical properties. In a preferred embodiment a single small capacitor or an array of capacitors is used to measure the dielectric properties of ink-jet droplets and the absolute drop volumes are derived. In an alternative preferred embodiment the relative differences in drop volumes are determined. A feedback circuit, such as one using lock-in technique, may be used to automatically adjust subsequent drop volumes.

Apparatus and procedure for the in situ measurement of quantities of polymer printed onto supportsA source of radiation 2 sends electromagnetic radiation onto a droplet 9, 10 of polymer solution or polymer dispersion, which is printed onto a support 4. A detector 3 measures the transmitted or re-emitted radiation. Controlled by a comparator device 6 and a control unit 5, 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: between two strip-shaped structured electrodes running transverse to each other, there is a functional layer of electroluminescent polymers that are delimited by the windows (10) of an insulating layer (5), the functional polymers define pixels of different colors R, G and B for a matrix, strip-shaped ridges of at least one additional insulating layer (15 and 20 in the case of two layers), which structure one of the electrodes, separate pixels of the same color from pixels of different colors, where pixels of the same color are located between two adjacent ridges.
