Definitions

  • the invention relates to a display device according to the preamble of the main claim. It is already known to display a stored image in electronic devices which have a display when the device is switched on or in the event of a missing image signal. For example, when a computer is switched on, a Budschirrnfirrna advertising logo is displayed. If necessary, a darkened screen can also be provided as such an image. The displayed image is prescribed by the device and can only be changed if necessary by replacing the relevant modules.
  • the display device with the features of the main claim has the advantage that a stored start and or rest image can be changed in a simple manner.
  • an input device is actuated and a new start / id / or still picture is transmitted to the display device via a suitable signal input.
  • This newly transmitted start and / or idle image is stored and will be output in future in the situations when the display of a start and / or idle image is required, for example when no or no image signal is present on the display device for output.
  • the display of the start and rest picture can thus be conveniently adapted to the wishes of a user or an operator of the display device.
  • the measures specified in the subclaims allow advantageous developments and improvements of the display device specified in the main claim. It is particularly advantageous to use the signal input to transmit the start and / or still picture, which is used to transmit the image data to be displayed with the display device to the display device. For an additional one
  • an image can also be selected and stored from an ongoing transmission of moving images without the need for a special, targeted image selection of this image from a data flow.
  • a data switch is preferably provided, which automatically performs a corresponding switchover between a line of image data into the memory for storing the start and / or idle image and the display.
  • a transfer to the playback of the stored image is also made possible in a simple manner when the image is reproduced from the memory.
  • a separate data input for feeding the start and / or still picture can advantageously also be provided, in particular if the data formats of the start and / or rest picture and the image data otherwise shown differ.
  • FIG. 1 shows a display device according to the invention.
  • Any display devices can be designed according to the invention.
  • these can be devices to which images are supplied externally, e.g. Monitors.
  • it can also be devices which contain image sources or which first generate the image data required for image display themselves.
  • this can be the generation from a data signal, e.g. a radio signal, e.g. generation of a television picture.
  • an image can be generated by converting data present on a data carrier in the display device into image data.
  • the use is advantageous for devices to which otherwise only image data are supplied externally in order to display them with the display device, e.g. Monitors and displays, in particular for displaying moving images.
  • This can e.g. Television monitors or video monitors, the video monitors serving to display any stored film information, e.g. for displaying image information stored on DVDs or video tapes.
  • still images e.g. Information boards with symbols and / or text, or pictures, e.g. are stored on a photo CD.
  • B demonstrations are advantageous because, on the one hand, the viewer is always shown a picture and, on the other hand, the picture can be used for advertising purposes, especially when the system is started or during a break.
  • a logo of the person who performs the image display or of the person who has set up the display device can be displayed with the display device. It is possible, for example, to make a corresponding display in a means of transport, for example a coach, and to save a logo of the bus operator as a start and / or idle picture. If the bus is sold to another company, the start and / or idle picture can be easily exchanged and adapted to the logo of a new owner.
  • the following is the invention is explained using the example of a display device to which the image information is supplied externally.
  • FIG. 1 shows a display device 1 in which an image data signal is transmitted to an image processing unit 3 via an image signal input 2.
  • the image processing unit 3 is preferably designed as a computing unit that receives the image data signals, e.g. converts an RGB signal, a video signal or a VGA signal into control signals which are directly suitable for output by means of a display unit 4 of the display device 1.
  • the control signals generated by the image processing unit 3 are passed on to the display unit 4.
  • the display unit 4 is e.g. implemented as a cathode ray tube or as a liquid crystal display.
  • the incoming image data must therefore be on the rows and columns e.g. a liquid crystal display divided and synchronized accordingly.
  • the image processing unit 3 generates a synchronization signal 5, which is also passed on to other functional units of the display device 1.
  • the electronic circuit shown in FIG. 1 can either be implemented by individual components, but it can also be combined in an electronic module.
  • Output of the start and / or idle image depends on the respective operating state of the display device 1.
  • the control unit 6 checks the operating state and, in the case of one or more predetermined operating states, causes the start and / or idle image to be output. Especially when there is no image data signal on
  • Image signal input 2 but also in the event of malfunctions or when requested via an operating unit (not shown in the figure), the start and / or idle image is output.
  • control unit 6 acts on a data switch 7 which has previously passed the control signals generated by the image processing unit 3 to the display unit 4. Due to the action of the control unit 6, the data switch 7 switches over to a supply of oil from a memory 8. A start and / or idle image stored in the memory 8 is now read out and passed on to the display unit 4 for output. This also happens if after when the display device is switched on there is still no image data signal at the image signal input 2.
  • control unit 6 switches back to a transmission by acting on the data switch 7
  • the memory 8 is preferably a non-volatile memory, e.g. as an EEPROM.
  • the image data are preferably stored directly in the memory 8
  • a user actuates an input device 9, which is preferably connected to the control unit 6.
  • the input device 9 can e.g. as an arranged on the outer housing of the display device 1, possibly provided specifically for this operation
  • the input device can also be designed in such a way that a certain key combination or input sequence of other control keys or. Remote control buttons of the display device must be pressed. In a further embodiment, it is also possible for certain switches inside a housing of the display device to be accessed. In another
  • a new storage of the image can also be triggered by a transmitted data signal or a data bus signal.
  • the input unit can be designed as a menu and or function selection in the display area of the display unit 4, in particular as a so-called “on screen display”.
  • the control unit 6 waits until the image currently transmitted from the image processing unit 3 to the display unit 4, which is preferably composed of individual pixels and image lines, has been completely transmitted to the display unit 4.
  • the control unit 6 now switches the data switch 7 such that the next complete image is written into the memory 8 by the image processing unit 3, so that the image stored there is overwritten.
  • the control unit 6 switches the data switch 7 again in such a way that the control signal output by the image processing unit 3 is now transmitted to the display unit 4 again.
  • the synchronization signal e.g. the image and / or line synchronization signal of the image processing unit 3 is transmitted both to the control unit 6, to the display unit 4, to the memory 8 and preferably also to the data switch 7, so that full images are always written into the memory 8.
