VUV Spectrofluorometer |
 The plasma display panel (PDP) is expected to dominate the flat panel display market due to an improved viewing angle, faster update speeds, and a crisper picture quality. Gas discharge excitation of RGB photoluminescent phosphors is used by the plasma display panels to produce the displayed picture. However, there is still a need for improvement in display performance; the high power requirements and relatively high cost of manufacture restricting the viability of the PDP compared to other display alternatives. The JASCO FLV-1000 VUV Spectrofluorometer can be used for the development and characterization of new PDP phosphors or the inspection and control of PDP manufacturing processes.
