Abstract (en)
[origin: WO2006131682A2] The invention concerns display screens, in particular emissive displays. The invention concerns a glass composition for making a display screen substrate having an infrared radiation transmission factor measured at 910 nm (T<SUB>IR910</SUB>) not more than 40 %, a global light transmission factor under illuminant D65 (TL<SUB>D65</SUB>) higher than 40 %, a dominant wavelength (D) ranging<SUP/>from 480 to 570 nm and<SUP/>a purity not more than 8 %, measured under a glass thickness<SUP/>of 2.8 mm, said composition comprising the following coloring<SUP/>agents, in wt<SUP>. </SUP>%: Fe<SUB>2</SUB>O<SUB>3</SUB>:0.4-2 %; FeO:0.1-0.6 %; CoO: 0-200 ppm; Se:0-30 ppm;<SUP/>NiO: 0-1000 ppm;<SUP/>CuO: 0-6600 ppm<SUP/>
