Direct observations of vacuum ultraviolet rays for surface-discharge ac plasma displays by using an ultra-high-speed electronic camera

摘要

Vacuum ultraviolet (VUV) rays emitted from Xe during the operation of surface-discharge ac plasma-display panels (PDPs) were observed directly by using a recently developed ultra-high- speed electronic camera. It is confirmed that 147-and 173-nm VUV rays are emitted from both the cathode and the anode simultaneously. The direct observation shows that the emitting area for 147- and 173-nm emissions above the cathode and the anode extends outward from the edge of the gap. These emission extensions are considered to be caused by a lowering of the electric field above the Area due to the accumulation of wall charges.
