“…Most of the energy deposited through electron impact excitation of xenon during the current pulse goes into Xe * , either directly or by cascading down from the higher excited states. The 3 P 1 and 3 P 2 states are depopulated mainly by UV photon emission from the 3 metastable or resonant states of atomic xenon with two rare gas atoms:…”

In this paper, we describe the principles of operation of a plasma display panel (PDP) and the physical mechanisms controlling the performances of a PDP in terms of light emission efficiency, lifetime and image quality. Emphasis is put on the physics of the plasma occurring in a PDP cell, on the discharge optimization, and on the analysis of recent results provided by experimental and numerical diagnostic tools. We focus on alternative current PDPs, where the plasma is generated by a dielectric barrier discharge, the configuration adopted by most PDP companies. The recent improvements and the remaining research issues are discussed.

“…An array of tiny cells (with dimensions ∼100 µm) located between these panels support microdischarges, which excite a phosphor layer to emit visible light of different colors. There is extensive literature on the principles of PDPs, including several review articles [18][19][20].…”

expands over the outer flat surface of the cathode and operates in the "normal regime". Transient relaxation oscillations are predicted in the plasma properties for intermediate discharge currents ranging from ∼0.1 mA to ∼0.3 mA; a phenomenon that is reported in experiments. The MPT, in its present configuration, is found to operate as an electrothermal, rather than as an electrostatic thruster. A significant increase in specific impulse, compared to the cold gas micronozzle, is obtained from the power deposition into the expanding gas. For a discharge voltage of 750 V, a power input of 650 mW, and an argon mass flow rate of 5 sccm, the specific impulse of the device is vii increased by a factor of ∼1.5 to a value of 74 s. The microdischarge remains mostly confined inside the micronozzle and operates in an abnormal regime. Gas heating, primarily due to ion Joule heating, is found to have a strong influence on the overall discharge behavior. The study provides crucial understanding to aid in the design of direct-current microdischarge based thrusters.
