Abstract: A crucible for an evaporation apparatus with the crucible having a length, a width, and a thickness is provided. The crucible comprises an evaporation side for receiving and evaporating material to be evaporated and a back side located on the back of the evaporation side with the evaporation side and the back side having a non-flat surface. Further, an evaporation apparatus having at least one crucible is provided.

Abstract: Embodiments of the present invention relate to a vaporizer apparatus with automatic feeding of a wire into a crucible. All of the parts of this vaporizer apparatus are mounted on only one carrier plate, such that a rapid mounting or dismounting, for example in clean rooms, is possible without particles being generated. In addition, a helical heating element is encompassed by a protective tube such that this helical heating element does not come into contact with the material to be vaporized.

Abstract: The invention relates to an evaporator arrangement with a crucible, wherein the crucible is divided into at least two zones, each of which is heated to different temperatures. The first zone is a melt-down zone and the second zone the evaporation zone proper. The evaporator arrangement is preferably for the evaporation of metals. If metals are evaporated, a metal wire is preferably guided into the melt-down zone. However, metal alloys can also be evaporated thereby that one or several metal wires comprised of different materials are guided into the melt-down zone. Between the melt-down zone and the evaporator zone a heating zone may be provided.

Abstract: An evaporator device for coating substrates, in particular for applying an aluminum layer of OLEDs. To attain high evaporator tube temperatures, such as are required for example for the vaporization of materials with low vapor pressure, the heating system is placed into the interior of the evaporator tube. The thermal losses are thereby minimized and higher tube temperatures are possible at comparably coupled-in heating power.

Abstract: A vapor deposition device for the vapor deposition of a substrate, and specifically particular of a substrate comprising heat-sensitive substances, for example OLEDs. To keep heat away from these substances, the vapor deposition device includes an evaporator tube with a special nozzle bar. This nozzle bar, which comprises several linearly arranged openings, projects with respect to the evaporator tube in the direction toward the substrate to be coated.

Abstract: A circuit for displaying graphics in a digital television receiver includes an MPEG decoder which has as input a video data stream in digital format, a central memory for storing decoded video data and graphics data, a video output unit and a graphics output unit to which video data and graphics data, respectively, are fed from the central memory, a mixer to which an output signal from the video output unit is fed, and a switch through which the output signal of the graphics output unit is selectively fed to the mixer. Horizontal and vertical synchronization signals from the MPEG decoder may be fed to the video output unit, while horizontal and vertical synchronization signals from various sources (including those from the MPEG decoder) may be selectively fed through a multiplexer to the graphics output unit. One buffer memory each may be placed before the video output unit and the graphics output unit, respectively, each memory unit buffering the corresponding data retrieved from the central memory.

Abstract: Aspects of the present invention concern a device and a process for continuous production of substrates provided with organic electroluminescent materials (OLED), especially OLED displays, screens, panels or other lighting elements, in which the device has a vacuum space and a transport device for transporting the substrates to be coated, which is at least partially arranged along the vacuum space and comprises carriers for the substrates, with the transport device comprising at least one endless loop for transport of the carriers and with the vacuum space being divided at least into two with a first part, in which is provided a first section of the transport device for transporting the carriers in a first direction (substrate-transport direction), and with a second part, in which is provided a second section of the transport device for transport of the carriers in a second direction (carrier-return-transport direction).

Abstract: The invention relates to a method for displaying graphics in a digital television receiver. A data stream which is provided with video data in the digital format is provided. A first YUV signal having a first frequency screen in the digital format is generated from the video data. The first YUV signal is converted into a second YUV signal having a second frequency screen in the analogous format. An RGB signal having a third frequency screen in the digital format is provided Said RGB signal is provided with graphics data. A mixed signal is provided by means of which the second YUV signal and the RGB signal are mixed together.

Abstract: A distortion-compensation method for a signal (S) that is transmitted in the blanking intervals of a video signal (CVBS) uses the received signal (S) to determine whether the signal (S) is subject to interference of a specific type. This interference is at least partially compensated for only when a specific limit value is exceeded. A separation stage according to the invention has a measurement apparatus (M) for detecting the presence of the specific type of interference.

Abstract: The circuit recovers teletext signals, notably VPS, TXT, WSS and similar signals, from a video signal with concurrent production of the standard scanning frequency of the respective teletext signal. The recovery circuit has a single phase locked loop circuit which generates a reference frequency from a basic frequency supplied by an oscillator circuit. The reference frequency is a multiple of the scanning frequency in question. To scanning frequency is extracted from the reference frequency with a frequency divider.

Abstract: The analog-to-digital converter device (24) provided for processing teletext signals is used for two purposes. In time slots in which no sync signal or teletext signal is separated from the video input signal (CVBS), the analog-to-digital converter device (24) is used for other tasks, e.g. for interrogating keypad inputs of an operator control unit (30).
