Color display screen comprising a contrast-enhancing pigment |
| 摘要 |
A color display screen having a coating which comprises at least a greend an/or a red phosphor as well as at least a pigment having the following composition:GaaInbZncAldOnSmSeoTepwherein 0.05<a<1.95 0.0</=n<0.3 0.05<b<1.95 2.1<m</=3 0.00</=c<0.09 0.0</=o<0.3 0.00</=d<0.2 0.0</=p<0.3 and n+m+o+p=3 and a+b++E,fra 2/3+EE c+d=2, yields a high-contrast and low-reflection picture, because the pigmentation in accordance with the invention is self-luminescent and its solid-solution properties enable its absorption properties to be accurately adapted to the emission spectrum of the phosphor. The solid solutions having the composition GaaInbZncAldOnSmSeoTep are characterized by steep absorption edges in the yellow-orange spectral range and by a high absorptivity. This permits thin pigment-containing layers and small quantities of pigment to be used.
