A display circuit and associated method, including a high-persistence display element (1018), such as a liquid crystal display device (130)) which visually displays sequences of informational image frames (260, 266) while minimizing interference between successive ones of the frames. A sequence of informational image frames are displayed upon the display element (1018), thereby to generate a visual signal which appears to scroll across the display element. Blank image frames (b) are interspersed between successive ones of the informational image frames to reduce thereby interference between successive ones of the informational image frames.

L'invention concerne un circuit d'affichage et un procédé associé. Le circuit comporte un élément d'affichage à persistance élevée (1018) du type affichage à cristaux liquides (130) qui affiche successivement des séquences de cadres d'images d'informations (260, 266), tout en minimisant les interférences entre les cadres successifs. Une séquence de cadres d'images d'informations est visualisée sur l'élément d'affichage (1018), pour générer un signal visuel qui apparaît en défilant sur l'élément d'affichage. Des cadres d'images vierges (b) sont dispersés entre des cadres successifs d'images d'informations pour réduire l'interférence entre les cadres successifs d'images d'informations.
