PHOSPHOR SCREEN WITH METAL BACK AND IMAGE DISPLAY |
摘要 |
<p>A metal back-attached phosphor screen includes a light absorption layer (2) and a phosphor layer (3) on an inner surface of a face plate (1) respectively, and a metal back layer (5) formed on the phosphor layer (3). The light absorption layer (2) contains an oxygen carrier prepared by adding a reducing metal to a metal oxide. A particle size of the oxygen carrier can be set to be 1 to 10 mu m. Besides, a phosphor material in which an activator such as Eu is added to a phosphor host material including oxygen such as Y2O2S, can be used as the oxygen carrier. In an image display device such as an FED, it is possible to eliminate a generation and an emission of a gas from the phosphor screen, and to improve an operation life of an electron emitting source. <IMAGE></p> |
