摘要

本研究主要在製作5 × 5 平方公分有機發光背光板，在研究中使用兩種不同面電阻的玻璃基板分別為4.6Ω/□ 和10Ω/□，並探討面電阻對元件的發光亮度、效率以及整面發光均勻度的影響。其元件結構為ITO/m-MTDATA/NPB/Alq3/LiF/Al，研究中發現使用面電阻4.6Ω/□ 的玻璃基板可提高元件的發光亮度(1784 cd/m2 @ 9V)、發光效率(8.485 mA/cm2 @ 9V)並且可使元件整面更均勻的發亮。最後在玻璃基板4.6Ω/□ 上先鍍上一層十字，其材料分別使用Au、Ag，意圖增加陽極的導電性。研究中發現使用Au的材料可比使用Ag和未加任何材料的發光亮度和效率都較大並且隨著Au的厚度越厚其發光亮度和效率會越大，其最大發光亮度可達到3057 cd/m2 @ 9V、發光效率12.047 mA/cm2 @ 9V。

並列摘要

This research mainly in manufactures 5 × 5 cm2 to the organic shining backlight, uses two kind of different sheet resistances in the research the glass substrate plate respectively is 4.6Ω/□ and 10Ω/□ , and the discussion surface resistance shines brightness to the part, the efficiency as well as the entire surface shines the uniformity influence. The structure of the device is ITO/m-MTDATA/NPB/Alq3/LiF/Al, in the research discovered the use sheet resistance 4.6Ω/□ glass substrate may enhance the part to shine brightness (1,784 cd/m2 @ 9V), the luminous efficiency (8.485 mA/cm2 @ 9V) and may cause part entire surface evener shining. Finally 4.6Ω/□ on first covers a cross in the glass substrate, its material separately uses Au and Ag, the intention increases the anode the electrical conductivity. In the research discovered uses Au the material to be possible to use Ag and not to add any material to shine brightness and the efficiency all comparatively greatly and thick goes past thick it along with Au to shine brightness and the efficiency can be bigger than, its most greatly shines brightness to be possible to achieve 3,057 cd/m2 @ 9V, luminous efficiency 12.047 mA/cm2 @ 9V.
