Effect of single crystalline MgO powder treatment of phosphor surface on discharge property of high-Xe AC plasma display panels
This paper presents a method of surface treatment of phosphor using a single crystalline MgO powder, and investigates effect of the surface treatment on discharge property of a plasma display panel (PDP). The discharge gas of the PDP was a 88% Ne12% Xe gas mixture at a pressure of 400Torr. For the surface treatment, a single crystalline MgO powder was mixed in methanol, sprayed on the phosphor surface, and annealed at 400C. This treatment suppressed glow discharge, which was observed very often in the weak discharges for reset of PDP if the phosphor works as a cathode, and provided a favorable condition for the PDP reset operation. When an experimental PDP fabricated using the surface treatment was driven by the twin reset waveform, the measured time delay for 99.9% cumulative probability of address discharge was 830ns, which meets the timing requirement for addressing a Full HD (19201080 resolution) PDP with the 10 sub-field single scan method.
