Definitions

  • the invention relates to a display with a Displaybeleuch ⁇ processing device and means for controlling the backlight means in response to a detected by means of a light-sensitive element luminous intensity of a light radiation occurring on the display.
  • the invention relates to a device with such a display and a method for operating a corresponding display.
  • CD t ⁇ P P- fu: n ⁇ P J p- 3 PJ ⁇ cn XF 3 P- ⁇ tr iP ⁇ JP
  • the light intensity is measured when the Displaybeleuch ⁇ processing device is straight.
  • the measuring device has a filter device which filters out the play generated by the lighting device Dis ⁇ proportion of the light intensity detected value.
  • a filter device which filters out the play generated by the lighting device Dis ⁇ proportion of the light intensity detected value.
  • a low-pass filter is sufficient for the filter device, since the ambient light essentially generates a direct current signal at the measuring element and the artificial light from the pulsating display lighting device is superimposed on this signal as an HF signal.

Abstract

L'invention concerne un dispositif d'affichage comportant une unité d'éclairage de dispositif d'affichage ainsi que des moyens pour réguler l'unité d'éclairage en fonction de l'intensité lumineuse, déterminée par un élément photosensible, d'un rayonnement lumineux apparaissant sur ledit dispositif d'affichage. Cet élément de mesure photosensible est intégré directement dans le dispositif d'affichage, par exemple dans un contrôleur de dispositif d'affichage COG (puce sur verre) ou un étage pilote de dispositif d'affichage COG.
