AC plasma display aging model and lifetime calculations

Investigation of wall and space charges decay using pulse technique in AC plasma display panel

“…The increase in the minimum sustain voltage from 100 s to 1 ms was due to the decay of the wall charges, which in turn depended on the surface state of the MgO film. It is well known that the surface properties of the MgO film are changed by the ion bombardment during a discharge [7]. Thus, the increased wall charge loss resulted from the surface state of the MgO film due to an insufficient discharge aging time.…”

“…The wall charges of a pixel in an ac PDP are also related to the surface state of the MgO film and definitely influence the discharge characteristics, display image quality, and reliability. Accordingly, the current study investigated the wall charge state of an ac PDP during the discharge aging process, an important process involved in manufacturing PDPs that stabilizes the display characteristics related to MgO [7]- [10]. Discharge aging studies have already been undertaken to understand the characteristics of the discharge voltage, discharge currents, gas pressure, and variable driving conditions [8].…”

Effects of Surface and Plate-Gap Discharges on Panel-Aging Characteristics in Alternating-Current Plasma Display Panel

“…The initial surface states of the MgO layer after deposition by the ion-plating method are very nonuniform. [1][2][3][4][5][6][7][8][9][10][11] Accordingly, the panel-aging process is required to obtain uniform MgO surface morphologies on both the bus and indium tin oxide (ITO) electrodes for stable discharge. Therefore, the surface state of the MgO surface in the front panel after the panel-aging process is important for producing stable reset and address discharges in PDP cells, as the discharge characteristics can vary depending on the state of the MgO surface.…”
