| dc.description.abstract | 液晶顯示器本身擁有厚度薄、質量輕與高亮度等多項優點，如何得到更好的顯示效果，開發高亮度、高均勻度、省電及輕薄的背光模組是相當的重要。本文將著重於研究以發光二極體為背光源的直下式背光模組設計。
為了增加背光模組的光學品質，我們設計發光二極體的封裝結構，以達到降低小角度的光能量，並用光學軟體作驗證。模擬結果證明所設計的封裝結構能有效實踐這目的，當將用所設計的封裝結構之發光二極體為直下式背光模組中背光源時，能得到較佳的均勻度與效率。 | zh_TW |
| dc.description.abstract | Liquid crystal displays have a lot of excellences, such as thin thickness, light weight and high brightness, etc. It is an important subject to develop a thin backlight module with the high brightness, uniformity, low power consumption. In this paper, we will investigate light emitting diode for a direct-lit backlight module unit of LCD.
To improve the optical properties of the backlight module, the lens of light emitting diodes for direct-lit backlight module unit is modified and analyzed to reduce the angular luminous intensity in the small angle range. And the results are verified by optical tracing simulation software. The results show that the modified lens method can effectively realize the purpose. Then, we put several LEDs are assembled with the modified lens in direct-lit backlight module, and the better uniformity and efficiency of the new backlight module are achieved. | en_US |
