Abstract

L'INVENTION CONCERNE UN DISPOSITIF D'ECLAIRAGE PAR L'ARRIERE POUR ORGANE D'AFFICHAGE ELECTRO-OPTIQUE. LE DISPOSITIF D'ECLAIRAGE 1 EST PLACE EN DESSOUS D'UN ORGANE D'AFFICHAGE ELECTRO-OPTIQUE 2, PAR EXEMPLE DU TYPE A CRISTAUX LIQUIDES, ET IL SERT A DIFFUSER ET REPARTIR LA LUMIERE VENANT D'UNE SOURCE PONCTUELLE 6, PAR EXEMPLE UNE LAMPE A INCANDESCENCE, SUR UNE GRANDE SURFACE. LE DISPOSITIF UTILISE UN ELEMENT 5 DE TRANSMISSION DE LUMIERE DOTE D'UN EVIDEMENT DESTINE A LAISSER ENTRER LA SOURCE, ET IL EST ENVELOPPE DANS UNE FEUILLE TRANSPARENTE MINCE 7 QUI COUVRE AUSSI BIEN LES SURFACES ANTERIEURE ET POSTERIEURE QUE LES BORDS DE L'ELEMENT DE TRANSMISSION DE LUMIERE. LE DISPOSITIF DE L'INVENTION EST A LA FOIS D'UNE STRUCTURE SIMPLE ET D'UN COUT PEU ELEVE.
