Paper Abstract

We have ever reported a phosphor screen, which is a 5-in. poly-crystal MgAl2O4 phosphor screen. The 5-in. poly-crystal MgAl2O4 phosphor screen has a very good performance, such as high luminance, high resolution, cheap cost and easily obtained. Recently we develop a high performance 5-in. poly-crystal phosphor screen. We deposit a multi-layer interface filter on the poly-crystal MgAl2O4 substrate. The filter is a multi-layer alternate high and low index of refraction film which was fabricated by depositing high index of refraction of titanium oxide and low index of refraction of silicon oxide. The measurement results show that the filter not only increases the MgAl2O4 phosphor screen’s white-D luminance, but also improves its chromaticity. The 5-in.R.G. B poly-crystal phosphor screens with the filter have 60% more luminance than those of common R.G. B poly-crystal phosphor screens, and the area of their chromaticity is almost 10% larger than that of common poly-crystal phosphor screen. The 5-in.R.G. B poly-crystal phosphor screens with the filter realize the authentic high performance.
