Lowering of the firing voltage and reducing of the discharge delay time in alternating current plasma display panels by a discontinuous spin-coated LaB6 film on the MgO protective layer

Abstract

A spin coated LaB6 discontinuous film is covered on MgO protective layer to improve the discharge performance of alternating current plasma display panels. Under the premise of high transmittance of more than 90%, a very small amount of polycrystal LaB6 powders added in an organic solvent are chosen as the coating solution. The discharge characteristics results show that with 250 torr 5% Xe-Ne pressure, the firing voltage and discharge delay time of the test panel with LaB6/MgO double protective layer are decreased by 13.4% and 36.5%, respectively, compared with that of conventional MgO protective layer, likely owing to the low work function of LaB6. Furthermore, the aging time of the proposed structure is comparable to that of pure MgO protective layer. Therefore, it will not increase the production costs and is highly suitable to be applied for alternating current plasma display panels with low electrical power consumption.

Investigation on the effect of nonlinear processes on similarity law in high-pressure argon discharges

“…High-pressure discharges are receiving considerable attention because of their wide industrial applications, such as plasma display panels (PDPs), ion sources, spectroscopy, micro-chips, and so on. [1][2][3][4][5] These discharges have been investigated by many authors through experimental diagnostics, analytical methods, and numerical simulations in the past decades. [6][7][8][9] Due to the sharply reduced discharge scales, the diagnostics of microscope parameters in high-pressure discharges are usually much more difficult than those in low-pressure discharges, since the commonly used techniques, such as plasma probes, can hardly be implemented.…”
