Abstract
Die Erfindung betrifft eine Schreibtafel (1) mit zumindest einem flächigen partikulärem Dickf ilm-AC-EL-Leuchtelement (2), wobei das EL- Leuchtelement zumindest eine obere transparente polymere Folie (18) aufweist und die Schreibtafel ein unteres flexibles Substrat (3) aufweist. Auf diesem unteren Substrat sind eine leitfähige Struktur (17) und die Energieversorgung (6) und Betriebselektronik (8) inklusive des zumindest einen Ein-Aus-Schaltsystems (7) und des Ladesystems (9) angeordnet ist. Die obere polymere Folie und das untere Substrat formschlüssig mit einem thermoplastischen Kunststoff (15) umrandend angegossen sind, wodurch die Schreibtafel zumindest spritzwassergeschützt ausgebildet ist.
