Definitions

  • the invention relates to a method for displaying an image on a display surface of a display.
  • images is to be understood in the broadest sense and includes text, graphics and any other visual information that can be shown on a display.
  • a disadvantage of the known screen savers is that they generally only become active after a predetermined latency period has elapsed, for example if a user of a computer has not given any input for a certain time or if there have been no changes to the display area for a predetermined time. When activated, these screensavers switch off the display or display a different image.
  • screen savers do not prevent burn-in effects in any way, since even with intensive keyboard input, for example when using a word processing program, the display changes only in a small area of the display area, whereas standing pictures are displayed in the remaining area, e.g. Window frames, menus, background images, etc. Conversely, however, the intensive input or the change of the image in a small part of the display area means that such a known screen saver is never active.
  • HUDs head-up displays
  • These HUDs display the same images over a long period of time, which is why, as with monitors, the known "burn-in effects" occur.
  • HUDs cannot switch to a screensaver mode during operation because they are ineffective and consequently the vehicle occupants would endanger.
  • the present invention solves this problem by providing a method and a display system for displaying an image on a display surface of a display, characterized in that, in trigger intervals, a display parameter is changed in at least one area of the display surface, the change for a subliminal period of time that is below the human perceptibility limit.
  • the present invention solves the problem of conventional screen savers which only come into effect after a display has not undergone any changes for a certain latency period or after no input has been made over the latency period, during which latency period constant heat development does occur the quality of the monitor and the display is impaired.
  • the screen saver according to the invention can work permanently without waiting for latency or the like and thus also permanently prevents the burn-in process.
  • the screen saver according to the invention works in such a way that the pixels of the display are used as uniformly as possible, their radiation changes again and again and the monitor temperature is kept constant.
  • the striking thing about this idea according to the invention is that a viewer does not notice anything about the mode of operation of the screen saver according to the invention, since it takes place in the subliminal area, that is, only for such a short duration that the human brain does not consciously perceive this change in the display parameter , However, the display does respond to this change in the display parameter, which prevents a burn-in process.
  • subliminal information that is information whose duration is below the ability of the human eye or brain to be blended into films, videos or television signals. It has been proven that a viewer the subliminal information can not perceive consciously, but reacts to it subconsciously. This effect is used, for example, to suggest a message to people, for example the message "Eat less”.
  • This effect of importing subliminal information has nothing to do with the present screen saver according to the invention.
  • the displayed information is not changed, influenced or replaced by other information, but a display parameter is changed to such an extent that the burn-in process is prevented.
  • the screen saver according to the invention thus also differs from all known screen savers in which, when activated, the image displayed on the screen is replaced by another image.
  • the screen saver works by changing a display parameter in at least one area of the display area for a subliminal period of time that is below the human perception limit.
  • the display brightness, color, illumination, contrast or focus of the display is preferably selected as the display parameter to be changed.
  • the subliminal time period within which a person cannot consciously perceive changes in a display parameter varies from individual to individual and also with the state of the day, etc. However, it has been shown that the subliminal time period is in any case short enough if it is 0 , 06 s does not exceed. It is also optionally provided that the viewer can adjust the sub-criminal duration in order to optimally adapt it to his own sensitivity and at the same time to achieve optimal protection of the display.
  • the display parameter in at least one area of the Display area is changed for an optionally adjustable supraliminal period that is above the human perception limit. This gives the user the certainty that the process is being carried out and the user is consciously reminded of the effectiveness and mode of action.
  • the trigger interval defines the time intervals in which the display parameter is changed.
  • a trigger interval of less than 20 s, preferably between 2 and 20 s has proven to be favorable for most types of display.
  • a value profile which profile can be a profile adapted to the ambient brightness, for example.
  • the trigger interval can only be varied within predetermined limits.
  • the method according to the invention is particularly suitable for implementation by means of a computer, whereby different approaches can be chosen. If, for example, the method is processed in a computer that has an operating system that allows the display of several superimposed display levels on a display surface, a transparent area can be provided as the top display level, which is not complete for the subliminal period of time according to the display parameter transparent mode is switched. If such a computer is also designed to display windows, a transparent window can be placed over at least one area of the visual information and the transparent window can be switched to a not completely transparent mode for the subliminal period of time according to the display parameter.

Abstract

L'invention concerne un procédé permettant d'afficher des images (9) sur une surface de visualisation (3), selon lequel à intervalles de déclenchement, un paramètre d'affichage (P) est modifié dans au moins une zone de la surface de visualisation (3) pour une durée subliminale, située en dessous de la limite de perception de l'homme. Le paramètre d'affichage (P) est sélectionné de préférence parmi les suivants: luminance d'affichage, couleur d'affichage, illumination d'affichage, contraste d'affichage ou mise au point d'affichage. Ces mesures permettent d'obtenir un économiseur d'écran fonctionnant en permanence et agissant sans qu'une personne qui l'observe ne puisse le percevoir. Le mode d'action indépendant du temps de latence garantit une illumination homogène optimale de la surface de visualisation, indépendamment de l'utilisation de l'ordinateur.
