Title (EN) AUDIO-VISUAL DISPLAY SYSTEM
(FR) SYSTEME D"AFFICHAGE AUDIOVISUEL
Abstract: front page image
(EN)An audio-visual display system has a number of channels each giving an electrical output in response to a selected audio-frequency input. Different lamps (18) are connected to the outputs of the channels and project coloured images onto a screen (14). To provide an enhanced visual effect the images are projected across the surface of a concave screen, preferably from the screen periphery Some lamps incorporate non-laminar light-transmitting elements (22) which give patterned images by refraction or from striations in the element, preferably in the middle to higher frequency range. The highest and lowest frequencies are preferably in the central region of the display. The lamps are preferably arranged in rows (X, Y, Z) at different distances from the screen.
(FR)Systeme d"affichage audiovisuel possedant un certain nombre de canaux donnant chacun un signal electrique de sortie en reponse a un signal d"entree selectionne a frequence sonore. Des lampes (18) differentes sont connectees aux sorties des canaux et projettent des images en couleur sur un ecran (14). Pour permettre un effet visuel ameliore les images sont projetees sur la surface d"un ecran concave, de preference a partir de la peripherie de l"ecran. Quelques lampes se composent d"elements (22) non laminaires transmettant la lumiere qui donnent des images a motifs par refraction ou par striations dans l"element, de preference dans la gamme de frequences moyennes a hautes. Les frequences les plus hautes ainsi que les plus basses sont situees de preference dans la region centrale de l"affichage. Les lampes sont de preference disposees en rangees (X, Y, Z) a des distances differentes de l"ecran.
