Abstract

Viene descritto un dispositivo a display luminosi per apparecchiature elettriche costituito da un contenitore, in cui è alloggiata una sorgente luminosa, superiormente al quale è disposto un pannello serigrafato con simbolismi alfanumerici; fra detto contenitore e detto pannello serigrafato è disposto un pannello a cristalli liquidi i quali, tramite un circuito di riduzione, vengono attivati a bassa tensione e resi trasparenti od opachi alla sorgente luminosa sottostante, al fine di evidenziare o meno detti simbolismi alfanumerici serigrafati sul citato pannello.
