摘要:
According to the present invention at least one layer of an optoelectronic acting material, for example an emitter layer, is applied on a substrate (1) and subsequently dried in accordance with a method for the production of luminous diodes. At least one layer is set vibrating before it is completely dried. This step addresses trapped air and uneven surfaces of the layer.
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.

A field emission cathode has a field emitter and an extraction grid, and the field emitter and the extraction grid can be moved relative to one another. Such a field emission cathode is highly durable and exhibits a longer lifespan. An x-ray tube has a field emission cathode composed of a field emitter and an extraction grid that can be moved relative to one another. Such an x-ray tube is highly durable and exhibits a longer lifespan.

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.

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.
摘要:
The invention relates to an organic light emitting diode (OLED), also referred to as a light emitting diode, which comprises at least one substrate, one anode, one hole transport layer, one emitter layer, one cathode and one encapsulation. It is proposed that an energy carrier, which supplies the voltage that causes the OLED to emit light, be integrated into the OLED. The energy carrier can be a battery (energy storage device) or an energy converter (photovoltaic element).
摘要:
In a planar radiation image detector with a number of photosensor elements arranged like a matrix, the photosensor elements being activated via at least one associated switching element and each exhibiting at least one storage element with a predetermined capacity, the storage elements are arranged above and/or below the photosensor elements. With such a planar image detector, an improved ratio of active detector surface to total detector surface is achieved.
摘要:
An electroluminescent organic device with an electromagnetic radiation emitting front side and having at least one pixel divided into at least two sub-pixels for emitting light with respectively different colors is disclosed. The device comprises a substrate; a first electrode over the substrate; at least one active organic layer over said first electrode for emitting electromagnetic radiation; a second electrode over said active organic layer, said second electrode being at least partially transparent to the electromagnetic radiation emitted by said at least one active organic layer; and a support carrying different kinds of pigments respectively aligned with the sub-pixels of the electroluminescent organic device, said support being arranged over said second electrode toward the radiation emitting front side of the device. Instead of a support with pigments a support with color changing media can be used. Furthermore, a method is disclosed to produce such a device.
