摘要

本論文主要研究是利用奈米碳管的極佳物理特性(高電流密度及 低導通電場)來製作平面光源的場發射端，我們運用厚膜網印技術， 在ITO 玻璃基板上完成二極式場發射平面光源結構。我們設計了幾種 不同的圖形，觀察圖形的邊緣對於場發射電流與亮度的影響，並以圓 點圖形和圓環圖形做比較。結果顯示陰極為圓環圖形時，可得到較高 的電流與亮度。我們將HOP-FLU 結構組裝在場發射平面光源中，提升 其亮度與均勻性。HOP-FLU 結構是LG. Philips 公司所開發的新型顯示 結構[1-3]，藉由加入HOP-FLU 結構，可以改善場發射平面光源的均 勻性以及亮度。我們利用Flex PDE 模擬軟體模擬出我們設計的結構， 並觀察電場強度與方向，最後分析模擬與實驗結果會在本論文中討 論。

The major purpose of thesis is using the excellent physical
properties carbon nano-tubes, such as high current density and low
turn-on electric field, to be the emitter of flat light sources. We carried out
the investigation of the field emission flat light sources on ITO glass
substrate based on the diode structure and thick-film printing technology.
We have designed different patterns to observe the electron emitting
effect on the pattern edge. We have also compared the current and
brightness for both of point and circle cathode patterns. The results show
that the circle cathode pattern have high current density and brightness.
We have also introduced the hop-flu structure to the field emission flat
light source to improve the brightness and uniformity. The hop-flu is a
new structure for field emission displays developed by LG. Philips
Displays Company [1-3]. The results show that the hop-flu structure can
improve the uniformity and brightness of the field emission flat light
source. We use the Flex PDE software to simulate the intensity and
direction of the electric field in the cathode and anode regions, and both
the simulation and experimental results are discussed and demonstrated in
this thesis .
