摘要


本研究將針對背光模組之中的背光源-冷陰極螢光燈管(Cold Cathode Fluorescent Lamp)在點燈狀態時,其電極濺射現象。我們利用X-ray觀察電極的濺射情形,隨著濺射情形的發生,燈管內的氣體也會消耗,所以填充壓力與濺射率(Sputtering Rate)之關係,成為我們研究重點之一。而燈管在高電流點燈的狀況下,也會加速電極濺射,我們利用實驗來說明電流密度與濺射率成正比之關係。最後實驗測試新的金屬Ni合金材料是否比目前使用的純Ni電極效果更好。

This research focuses on the CCFL which is the light source of the backlight module. Life of electrode will be researched on the condition of low pressure of filled gas and high current. In order to investigate sputtering condition of electrode, we use X-ray to detect it and quantify the comsuption of that. After understanding how pressure of filled gas affected electrode, the method of current density is decided to estimate the life of electrode on the same material of that. At last , new alloy of Ni is estimated again to check if it’s better than pure-Ni electrode or not.
