Abstract

L'invention concerne un dispositif d'affichage à cristaux liquides comprenant un système d'alimentation par énergie solaire placé à distance considérable sous une couche de cristal liquide de sorte que la lumière captée par ladite couche de cristal liquide traverse celle-ci pour arriver au bloc d'alimentation solaire. Le dispositif d'affichage est également équipé d'une antenne disposée sur la couche de cristal liquide. L'antenne utilise des conducteurs qui n'entravent pas considérablement l'affichage ou le passage de la lumière à travers la couche de cristal liquide.
