In this paper, a 6kW high voltage plasma power supply system was developed for LCD cleaning. Dielectric-barrier discharges (DBDs), also referred to as barrier discharges or silent discharges have for a long time been exclusively related to ozone generation.
However, the needs for high efficient cleaning and low cost made high voltage plasma cleaning techniques to be developed and to be improved. UV lamp systems have been used for cleaning of display panels of TFT LCD or Plasma Display Panel ( PDP). Kim, Gyu-Sik Won, Chung-Yuen Choi, Ju-Yeop Yim, C. The simulation results can help us optimize the driving scheme of the SM- PDP.Ītmospheric plasma generation for LCD panel cleaning The priming particles in the beginning of the addressing period are related to the slope of the ramping down voltage pulse. Moreover, the variation of the ramp slope will also bring a few modifications to the wall voltage. The simulation results illustrate that the wall voltage is mainly decided by the terminal voltage and the firing voltage at the end of the ramp reset period. Some basic parameters such as the slope of the ramp pulse and the terminal voltage of the ramp reset period are varied to investigate their effects. Yang, Lanlan Tu, Yan Zhang, Xiong Jiang, Youyan Zhang, Jian Wang, BaopingĪ two-dimensional self-consistent numerical simulation model is used to analyse the effects of the ramp reset pulses on the address discharge in a shadow mask plasma display panel (SM- PDP). Phys., 48, 4754 (1977).Įffects of ramp reset pulses on the address discharge in a shadow mask plasma display panel These results should serve as useful parameters in discharge simulation for the PDP. The results are as follows: For ions, He:0.481 and Kr,Xe:0, assuming that there are no impurity levels in MgO For metastables, He:0.491, Ne:0.489, Ar:0.428, Kr:0.381, and Xe:0.214. These values are calculated in the present study after them.

However, the values of γ for other rare gas ions and their metastables necessary for a full color PDP have not yet been calculated. For metal cathodes, we made a comprehensive examination^1 of γ for all rare gas ions and metastables according to Hagstrum's theory.^2 For γ of MgO, which is the useful insulator cathode, Aboelfotoh et al.^3 calculated the values for Ne and Ar ions supposing a monochrome PDP. The secondary electron yield γ of the Plasma Display Panel ( PDP) cathode is an important research object because it is closely related to the discharge voltages etc. Study on the Secondary Electron Yield γ of Insulator for PDP Cathode MORE RECENT MONITOR IN UPPER CENTER FOR “LTR FLUX MONITORS” - Physics Assembly Laboratory, Area A/M, Savannah River Site, Aiken, Aiken County, SC THESE PANELS WERE WHERE THE A-MOTOR TAPES WOULD HAVE BEEN VISIBLE IN THE CONTROL ROOM.
