GLASS-CERAMIC ARTICLE WITH LUMINOUS DISPLAY

摘要

The present invention relates to an article having at least one luminous area, particularly for display purposes, particularly a white area, said article comprising at least one glass-ceramic substrate having a light transmission from 0.8% to 40% and an optical transmission of at least 0.10, at least at a wavelength within the range from 420 to 780 nm, at least one light source, particularly a light-emitting diode, having an emission peak at a wavelength between 430 and 490 nm, and at least one luminescent compound emitting in the area of the CIExyY (1931) three-color diagram delimited by the following coordinates (x, y):;x0.26580.20000.30000.42290.2658y0.72430.39500.34050.57560.7243
so as to form at least one luminous area, particularly a white area, in particular for display purposes, in at least one area of the plate.
