Abstract

L'invention porte sur une structure qui comporte de première (23) et seconde (24) couches de guidage de lumière, chacune comportant un motif de matière photoluminescente ; et une source de lumière (28a, 28b) configurée pour diriger la lumière dans les première et seconde couches de guidage de lumière pour éclairer sélectivement les motifs des première et seconde couches de guidage de lumière. Une couche d'écran à la lumière (25) peut être disposée entre les couches de guidage de lumière pour empêcher la lumière d'une couche d'entrer dans l'autre couche. La structure peut être utilisée dans un clavier, auquel cas les motifs peuvent être des ensembles de caractères. La structure peut également être utilisée pour revêtir un dispositif électronique. La structure peut comporter davantage de couches de guidage de lumière fournissant ainsi d'autres ensembles de caractères ou de motifs décoratifs.
