Abstract:	本研究利用氣體放電產生真空紫外光激發螢光粉產生可見光原理，運用於平面光源的技術。藉由關鍵製程網板印刷將電極、誘電層、螢光層等結構印刷於透明平板玻璃，再經烘箱乾燥、高溫燒成爐將材料層燒結附著於玻璃，接著將玻璃塗膠後加上間隔層及邊框將上下兩片玻璃組立，再經真空設備進行抽真空，最後灌入惰性氣體後進行密封，建構無汞平面光源之製程技術流程。並以高電壓驅動氙氣惰性氣體進行放電現象產生真空紫外光，激發螢光粉之表面層產生可見光即為平面光源。本論文係著重於平面光源光學特性的研究(包含亮度、色溫、色座標)，對於製程中所影響之因子藉由實驗規劃進行研究，依據材料規劃實驗條件 (1)混合不同R、G、B螢光粉比例研究其光學特性 (2)定壓力下混合不同比例之惰性氣體研究其光學特性，針對此兩種因素對平面光源光學特性影響為主要軸心進行分析。以期許了解平面光源光學特性的因素，並將平面光源應用於薄膜電晶體液晶顯示器之背光模組。 This research utilizes gas to discharge the principle. Then it produces the visible light principle to produce the vacuum ultraviolet ray and excite phosphor powder, apply the technology of the FFL(Flat Fluorescent Light) to. According to critical process print the following structure in the transparent plate glass, such as electrode layer、dielectric layer、 phosphor layer etc.. Utilize the dry material of oven, adhere to the material the glass through the furnace. Utilize the spacer and frame to assemble two pieces of glass after dispensing frit . And then draw out the vacuum by the vacuum equipment. Sealing this plate after being full of inert gas finally. Set up mercury-free FFL flowchart . It produces the vacuum ultraviolet ray(VUV) to excite the xenon and discharge with the high voltage. It is FFL that the surface which excites phosphor powder produces the visible light. This thesis department focuses on the research (includes luminance , colour temperature , color coordinate ) of the FFL optics characteristic. Plan to carry on research with the experiment according to the factors influenced. Content the following of the experiment :(1)Mix powder of phosphor of R 、 G、 B different weight percentage and study FFL optics characteristic. (2)Mix the inert gas of different weight percentage under the same pressure and study FFL optics characteristic. Analyze for the main axis to these impacts on FFL optics characteristic of two kinds of factors. Expect to find out about the factor of the FFL optics characteristic. And apply the FFL to the backlight module of TFT-LCD.
