  • 本論文為了探討交流電漿顯示器條紋現象(Striations)的物理機制,作了第一階段的系統建立與初步光電量測。首先建立Intensified- CCD量測系統來作光譜與影像量測,藉以觀察不同電壓波形參數下,條紋現象隨空間與時間的變化情形,並搭配現有的光譜儀與光電倍增管量測系統、電壓探針與電流探針來量測氣體放電時光強度、影像、驅動電壓與放電電流隨時間變化的情形。
    實驗結果顯示,在K.Yoshikawa等發展的驅動波形架構下,維持電壓脈衝的振幅與頻率提高,放電電流與光強度增強且起始時間縮短,維持電壓上升時間越長,放電電流與光強度減弱且起始時間增加;其中Intensified-CCD光譜量測在時間解析上能力較佳。而在影像量測上也為上述實驗提供空間上解析,並發現波形變化會影響電極表面的壁電荷分佈情形,使得氣體放電影像在圖形與兩電極間光強度的分佈會有所差異。

    最後建立高真空系統與加熱機制,並成功點燃直流放電管且發現正極區中的條紋現象;唯有依相似定律(Similarity law)來研製的大尺寸電漿顯示器(Macro-PDP cell)尚未驅動成功,留待後人於第二階段實驗中再深入研究,如此即可簡單地改變面板結構參數,並將量測結果與實際電漿顯示器作比較。


    For studying the physics of striation phenomenon in the AC plasma display panel cell (PDP), we achieve to establish the experimental system and the optoelectronic measurements for the first step. We establish the intensified-CCD system (ICCD) to measure the temporal spectrum, spatial and temporal image acquisition with different driving waveforms for studying the images of striations. With the spectroscopy, photomulti- tube(PMT) system, voltage probe and current probe, we can observe the light intensity, image, voltage and current of gas discharges with time variation at the same time.
    The experimental results show that under the driving waveforms developed by K.Yoshikawa et al., if the voltage and frequency of sustain pulse increases, the discharge current and light intensity grows but the initial time is faster; if the rising time of sustain voltage increases, the discharge current and light intensity decay but the initial time is slower. We also found that the intensified-CCD has excellent performance of temporal analysis. About the image acquisition, the distribution of wall charges on the electrode surface changes by variation of driving waveforms and the patterns of discharge images and the distribution of light intensity above the surface of the sustain electrodes will have some different results.

    Finally we establish the high vacuum system and heating system, and then succeed in firing DC gas discharge tube and found the striations in the positive column. It is a pity that the macro-PDP cell ruled by similarity law hasn’t been fired successfully, and need to be research in advance at the second step. If we could succeed in macro-PDP cell, we can change the parameters of panel structures and gas cheaply and simply, and compare with the difference between the macro-PDP cell and real PDP production.
