Study of preparation of low voltage cathodoluminescent phosphor and application on field emission display screen

摘要

Summary form only given. High efficiency low-voltage cathodoluminescent phosphor is one of the key materials in developing field emission displays. High brightness, high resolution and fine images of phosphor screen are related to the size of phosphor particles and the layer thickness in the screen. Low voltage phosphor powder for field emission display (FED) has been triturated to super small grains, after special treatment, the phosphors are deposited onto the anode screen of FED devices, with printing method, the phosphor powder was made up to different phosphor thin films with varied thickness. SEM was employed to observe the phosphor particles and the phosphor thin films. Experiments have been carried out on analyzing the different characters of the cathodoluminescence of the treated low voltage phosphor and its phosphor screen.
