摘要:
An organic layer (1) is applied to a transparent carrier (2) in such a way that different partial regions with different refractive indices are formed in the layer. Owing to deflection at the phase boundaries within the layer, fewer photons remain trapped in the layer as a result of wave-guiding losses than in the case of homogeneous layers.

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.
摘要:
A planar electronic component has a functional layer with an optoelectronic or a circuit configuration between a substrate layer and a covering layer. A sealing frame or sealing ring is disposed between the substrate layer and the covering layer and connected to them by an integral joint surrounding the functional layer. The seal very largely protects the functional layer against hazardous external influences, in particular against moisture and oxygen. A mechanical connector, whose adhesive characteristics are matched to the materials of the covering layer and of the substrate, is provided in addition to the sealing ring. The connector fixes the substrate and covering layers mechanically with respect to one another, and may reduce the risk of partial or complete detachment in the event of deformation of the electronic component, in particular as a result of thermal expansion and/or mechanical loading.

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.

The invention relates to a material for applying thin organic layers having a conductivity that can be set in a defined manner. The material comprises at least one mixture consisting of two different fractions of a functional polymer, preferably in a solvent, and is applied, for example, in the form of a thin and low-conductive functional layer of an organic light-emitting diode (OLED) by means of different application techniques.
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.
摘要:
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.
