Abstract

L'élément émetteur de lumière (24) disposé en lignes et en colonnes constitue l'élément unitaire dont est équipé le tableau d'affichage matriciel. L'élément comprend un ou plusieurs tubes à décharge (10, 11, 12). Pour un tableau restituant des images (texte ou vidéo) en couleur, la paroi interne de chacun des tubes est revêtue d'une substance fluorescente qui rayonne une couleur rouge, verte et bleue respectivement. En variant indépendamment l'intensité de la lumière émise par chacun des tubes colorés, on obtient à la sortie de l'élément (24) une lumière dont la longueur d'onde résultante peut s'étendre sur tout le spectre visible. L'invention peut être utilisée sur un tableau d'affichage disposé par exemple dans un stade ou lors de manifestations impliquant un grand nombre de personnes.The light emitting element (24) arranged in rows and columns constitutes the unitary element with which the matrix display board is equipped. The element includes one or more discharge tubes (10, 11, 12). For a table reproducing images (text or video) in color, the internal wall of each of the tubes is coated with a fluorescent substance which radiates a red, green and blue color respectively. By independently varying the intensity of the light emitted by each of the colored tubes, there is obtained at the output of the element (24) a light whose resulting wavelength can extend over the entire visible spectrum. The invention can be used on a display board arranged for example in a stadium or at events involving a large number of people.
