Abstract
Using a Scrap protective layer, the discharge can be sustained at both a lower voltage and 代写留学生论文lower current than that with an MgOprotective layer, and a higher luminous efficiency can be obtained at these lower ranges of both voltage and current. When the same sustain pulse voltage was applied, compared with the discharge current waveform of the panel with the Go protective layer that of the panel with the Scrap protective layer showed a larger peak current and shorter time lag of the discharge current. Regarding ion bombardment, the life of Scrap film remains nearly 80% of that of Go film.

1. Introduction
PDP electrodes are covered with glass, which is usually self-coated with a protective layer. Go film is the normal choice forth protective layer because of its low-voltage characteristic and good durability under ion bombardment, and has been used for about 30 years [1]. However, other materials have been tried in order to reduce the drive voltage further. A mixed crystal Sarcomas reported as a low work function cathode [2]. In early studies on the monochrome AC PDP, the firing voltage of a panel with 53kPa Next 0.05 – 0.5% was found to be 30 V lower when protective layer made of mixed crystal Scrap was used instead forgo [3]. However, the luminous efficiency of the panel, which radiates the monocular of Ne luminescence, was not measured. Ina previous experiment using a monochrome PDP with an SrCaOprotective layer, the Ex. content of 0.05 – 0.5% was very much smaller than the present ratio of about 10% for color PDPs.Twenty-six years after the experiment using the monochromePDP, we achieved the voltage reduction of a color PDP with theSrCaO protective layer [4]. The sustain pulse voltage of the panel for 66 kappa Next 5 – 30% with the Scrap protective layer is 20– 40% lower than that with the Go protective layer.

The use of higher Ex. content greatly increases the discharge efficiency and has recently been established as an effective way to improve luminous efficiency. However, the firing and sustain pulse voltages also increase significantly with higher Xecontent, thus raising the cost of electronic components and increasing the power consumption of the drive circuit. The SrCaOprotective layer is useful to overcome these drawbacks.

In this paper, we investigate the luminous efficiency of a panel with the Scrap protective layer. The composition and structure of the Scrap protective layer deposited onto the surface of the glass dielectric layer were also investigated. We also measured the sputter etching rate of Go, So and Scrap films to compare the durability of these films under ion bombardment.
