Abstract :
A new kind of MgAl2O4 phosphor screen for projection display is reported. The 5 inch phosphor screen is fabricated by depositing powder on MgAl2O4 substrate. Because MgAl2O4 has the characteristics of higher heat conductivity than the conventional glass faceplate, the phosphor screen achieves very high brightness, good contrast ratio, high resolution and long lifetime, and therefore realises large-screen projection display.
