“…Several different types of priming species have been cited, including space charges and metastables from preceding discharge cycles 2,3 and exo-electron emissions from MgO. [3][4][5][6][7] The decay time for the space charge by recombination reactions was estimated to be less than 50 µsec 8 and the decay time for the metastable Xe* 2 dimer through the conversion reaction to Xe* was estimated to be less than 100 µsec. 5 However, the conventional address-display separated (ADS) driving method of ACPDPs uses sub-fields for which the time frame is longer than 1 msec.…”

Thus, this short decay time of the space charge and metastables makes such sources unsuitable as priming sources for discharge cells kept OFF at the preceding sub-fields.…”

“…Nagorny et al 5 estimated from their numerical simulation study on ramp discharge of ACPDPs that an external supply of~100 electrons/µsec to each discharge cell is needed in order to make-up for the charge losses to the walls as well as through recombination reactions. This corresponds to approximately 10 nA/cm 2 of exo-electron current density.…”

Abstract— Exo‐electron emission from MgO thin film was measured by attaching a high‐precision current sensor to the address electrode of the rear plate of an ACPDP test panel. The measured results revealed that the exo‐electron emission currents can vary very sensitively with the type of doping elements used in MgO film and the measuring temperature. The activation energy of the exo‐electron emission estimated from the emission curves indicated that the trap levels are between 0.05 and 0.32 eV below the bottom of its conduction band. This suggests that shallow electron‐trap levels within MgO film are mainly responsible for the exo‐electron emission.

“…As a result of recent advancements, plasma displays have become high-definition (HD), and thus the addressing time has become a critical issue. 1 A novel ACPDP having a shadow-mask (SMPDP) with an effective structure with lower cost and lower driving voltage is presented. [2][3][4] The distinct difference between SMPDP and a conventional ACPDP is that the dielectric barrier ribs are replaced by a single metal shadow mask.…”

Effects of shadow‐mask voltage on the discharge in shadow‐mask PDPs

Abstract— A new type of ACPDP with a shadow mask (shadow‐mask PDP, SMPDP) has been developed, featuring an effective structure and lower cost. The distinct difference between an SMPDP and a conventional ACPDP is that the dielectric barrier ribs are replaced by a single metal shadow mask. A three‐dimensional self‐consistent fluid model was used to analyze the effects of the shadow‐mask voltage on the discharge for a simplified driving scheme. The simulation results indicate that by selecting the appropriate shadow‐mask voltage, the addressing speed can be improved due to the local strong electric field. The steady discharge in the sustaining period will not be affected by changes in the shadow‐mask voltages in the addressing period. While in the sustaining period, the shadow‐mask‐voltage variation can directly affect the sustaining discharge. The floating shadow mask in the sustaining period is beneficial in achieving a stable sustaining discharge.

“…The glow discharge can cause misaddressing, decrease the contrast ratio and the voltage margin, and limit the choice of PDP drive waveform. The cause of glow discharge in the set-up period may be related to either surface morphology or to secondary electron emission by the phosphor [3][4][5].…”
