A method for displaying images on a display device. The display device includes a general processing unit, a display having several display units and an individual processing unit per display unit. In order to display the images, data concerning the image to be displayed are transmitted from the general processing unit to the individual processing units in the form of a data stream, in that there is a control communication between the general processing unit and each of the individual processing units in the form of control signals. The data from the data stream are collected at every individual processing unit as a function of the control signals transmitted to the individual processing units.

The invention claimed is: 1. A method for displaying images on a display device, the display device including at least one general processing unit and a display comprising a plurality of display units with corresponding processing units, the method comprising the steps of: transmitting a data stream comprising data concerning the image to be displayed from the general processing unit to the individual processing units; providing a control communication comprising a plurality of control signals between the general processing unit and each of the individual processing units, the control communication sent from the general processing unit to each of the individual processing units being individually distinct from the data stream sent to each processing unit; collecting data from the data stream at each of the individual processing units as a function of control signals transmitted to the individual processing units; providing distributed signal processing between the general processing unit and the individual processing units; providing a distributed signal processing for the signals related to the image display; and raising the line frequency in the general processing unit in order to eliminate interline flicker and to obtain higher image resolution. 2. The method according to claim 1, wherein the display units are serially coupled. 3. The method according to claim 1, wherein the display units consist of LED panels. 4. The method according to claim 1, wherein the distributed signal processing is at least provided for signals related to color rendering, and/or brightness, and/or contrast. 5. The method according to claim 4, further comprising the step of making at least one individual adjustment at the individual processing units, said at least one individual adjustment being selected from the group consisting of: adjustment of the color coordinates, adjustment of brightness, adjustment of contrast by dynamic sample weight distribution, corrective adjustment as a function of the temperature and/or age of the display unit, adjustment of the transfer functions, and enlargement of the incoming video signal in the horizontal direction and/or vertical direction. 6. The method according to claim 5, wherein contrast adjustment comprises adjusting the linear connection between the input signal and the output signal towards a non-linear connection in each individual processing unit as a function of the command provided by the control signals. 7. The method according to claim 5, wherein at least one individual adjustment is made at the general processing unit, said adjustment being selected from the group consisting of: image stabilization and/or noise suppression, tracking of the illumination of the image, histogram equalization as a function of the entire image to be displayed, observing a cue flash and making a correction, and reduction of the image in relation to the original input image in the horizontal direction and/or vertical direction. 8. The method according to claim 1, further comprising the step of providing distributed signal processing to minimize image flickering of the general processing unit and the individual processing units. 9. The method according to claim 1, further comprising the step of making individual adjustments to maintain the display unit in operating frequency-independent both vertically and horizontally. 10. The method according to claim 1, wherein an automatic pulse width adjustment is realized in the individual processing units. 11. The method according to claim 1, further comprising the step of raising a frequency in the individual processing units to eliminate surface flicker. 12. The method according to claim 1, further comprising the step of providing distributed signal processing at least for signals which determine image geometry. 13. The method according to claim 12, further comprising the step of transmitting control signals to the individual processing units to indicate which part of the image should be displayed at the display unit, the individual processing units collecting data from the data stream, processing the data and displaying the data as a function of the control signals. 14. The method according to claim 1, comprising the step of providing for dynamic image stabilization. 15. The method according to claim 14, wherein at least one technique is applied for the dynamic image stabilization, said at least one technique being selected from the group consisting of: a time-dependent image stabilization arranged for verifying pixels of an image and including determining alterations occurring between successive images and providing an image stabilization effect before the images are displayed; a frequency dependent image stabilization arranged for verifying how alterations occur in pixels of an image positioned next to one another and providing an image stabilization effect before the images are displayed; an amplitude-dependent image stabilization; and an image stabilization as a function of an entire image content. 16. The method according to claim 1, wherein the individual processing units are provided with master clock correction. 17. The method according to claim 16, wherein different signals are used for red, green and blue signals, and transmission errors in the red, green and blue signals are minimized due to the master clock correction. 18. The method according to claim 1, wherein the display includes a plurality of LEDs driven by an uninterrupted current during operation such that the length of time for which the current is switched on is used as a control parameter. 19. The method according to claim 18, wherein the current is altered to adjust the brightness and the contrast. 20. The method according to claim 1, wherein the data stream and the control signals are transmitted via separate data lines. 21. The method according to claim 1, wherein the data stream and the control signals comprise a single pulse train such that a first plurality of intervals of the single pulse train are reserved for the data stream, and a second plurality of intervals of the single pulse train are reserved for the control signals. 22. The method according to claim 1, wherein the data stream and the control signals are transmitted to each of said display units, and at least some of the individual processing units are provided with a master clock correction arrangement.
