Abstract

Il trovato riguarda uno schermo di protezione per visualizzatore avente una lastra che impedisce la visione a persone diverse da quelle direttamente di fronte al visualizzatore.Il problema tecnico è quello di realizzare uno schermo di protezione che consente la visione del visualizzatore solo entro un angolo piuttosto limitato ed impedisce la visione alle persone fuori da quell'angolo.Una lastra 13 è fissata su una cornice 12 per essere posizionata di fronte ad un visualizzatore 11 tramite fustellati di velcro adesivo 27 avente una prima parte 28 fissabile sulla cornice 12 e la seconda parte 29 fissabile sul visualizzatore 11. La lastra 13 comprende una pellicola del tipo a persiana 18 che definisce delle microfinestrelle 22 parallele per definire un angolo di visione limitato 23.
