摘要:
The invention relates to an organic, coloured electroluminescent display with the following characteristics: a functional layer of electroluminescent polymers is positioned between two strip-type structured electrodes, running perpendicular to each other, said polymers being delimited by the window (10) of an insulating layer (5); the functional polymers define pixels of different colours R, G and B for a matrix; strip-type struts 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 colour from pixels of a different colour, whereby respective pixels of the same colour lie between two adjacent struts.

The invention relates to a passive matrix display comprising structured pixels and a structured second electrode on the basis of electroluminescent polymers. The inventive display is specifically characterized in that functional polymer layers (12 and 14) are connected to a first electrode (1) and are delimited by windows (10) of an insulating window layer (5). At least one further insulating strip-shaped layer (15 and 20 for two layers) is disposed between the windows of the first insulating layer (5) and is disposed at an angle to the first electrode strips in the form of a web. A second electrode (2), structured by these webs, is connected to the functional layers and extends at an angle to the first electrode strips between the webs.

The invention relates to a device and a method for the continuous printing of organic light-emitting diodes (OLEDs). According to the invention, a substrate with or without a coating is placed on a roller as strip material and guided through a device comprising moveable screens in order to print by means of screen printing.

The invention relates to an organic electroluminescent display in which functional layers (20) are delimited by first strip-shaped connecting elements (10) whereby enabling the functional layers to be applied over a large area. The functional layers are located on a first electrode layer (5A) that, in turn, is located on a substrate (1). A second electrode layer (25A) is situated on the functional layers.

An organic layer (1) is applied to a transparent carrier (2) in such a way that several partial segments with different refractive indices are configured in the layer. Fewer photons remain trapped in the layer as a result of waveguide losses than in homogenous layers due to diversion at the phase limits within the layer.
摘要:
The invention relates to a method for applying at least two, for example, electroluminescent layers to a substrate over a large area. In one method step A), spacers (5) are structured on the transparent substrate in such a manner that, during the application of a second functional layer (11), they prevent a first functional layer (10), which is already located on the substrate, from coming in contact with a part of a printing machine responsible for transferring the functional layers to the substrate. In two additional method steps B) and C), the first functional layer (10) and the second functional layer (15) are applied over a large area, for example, by means of large-area standard printing methods.

The invention relates to a passive matrix display on the basis of electroluminescent polymers, comprising a structured matrix from pixels and a structured second electrode with electrode terminals. The inventive display is specifically characterized in that the functional polymers are delimited by windows (10) of an insulating layer (5) and are connected to a strip-structured first electrode (1) and a likewise strip-shaped second electrode (2) that extends at an angle to the first electrode and that is connected to the electrode terminals (2a). Windows (40) are disposed in the insulating layer and are disposed above the electrode terminals (2a) for the second electrode, or zones of the insulating layer are disposed between the electrode terminals. An encapsulation (30) is provided that covers the insulating layer with the functional polymers and the second electrode but leaves blank one end each of every electrode terminal (2a).
摘要:
The invention relates to a method for producing organic light-emitting diodes (OLED"s) (2.3.5). Whereas in prior art production methods, the color conversion layers (4) were applied in a contactless manner to a substrate (1) using ink jet printing methods, the invention now uses printing methods which directly impinge upon the substrate, namely methods involving the use of a printing form. Flexographic printing and offset printing, for example, function according to this technique.
