CA 2497095

A display device includes an edge-lit light-transmitting sheet having first and second opposed parallel surfaces. A matrix is applied to at least one of the first and second surfaces and comprises a series of lines extending between opposed edges of the sheet. The spacings between the lines and/or the thicknesses of the lines are so chosen as to obtain a desired intensity of illumination at selected areas of the sheet.

L'invention concerne un dispositif d'affichage présentant une feuille de transmission de lumière de panneau lumineux comportant des première et seconde surfaces parallèles opposées. Une matrice est appliquée sur au moins une des première et seconde surfaces. Cette matrice comprend une série de lignes s'étendant entre les bords opposés de la feuille. Les espacements entre les lignes et/ou l'épaisseur des lignes sont ainsi choisis de manière à obtenir une intensité d'éclairage souhaitée au niveau de zones sélectionnées de la feuille.
