摘要: 
目前液晶顯示器主流是薄型化,因此背光技術的趨勢也從LED取代CCFL。而背光模組中包含光源、導光板、反射片、菱鏡片與擴散片等結構。本文研究著重在導光板層,以微透鏡作設計結構,並探討利用微透鏡對背光模組的效益。

實驗先以建模軟體建製簡易背光模組,其設計導光板上下層附有微透鏡。將此資料轉換至光學軟體設定各結構的光學性質後,比較不同設計之背光的亮度與均勻度差異。將模擬資料作為參考架構。再來,操作本研究室噴墨機台進行噴印製作微透鏡在導光板,並封裝成3吋背光模組。最後,量測試品的亮度值與均勻度。

The current it is a main of thin package at the LCD monitors, so the trend of backlight technology is CCFL to LED. The backlight unit is consisted of light source, light guide plate, reflector plate, brightness enhancement film and diffuser sheet. This study is focused on light guide plate layer, and the design structure is the micro lens. And we explored the use of micro lens to the benefit of the backlight unit.

First, used the modeling software form a simple backlight module, and the design was top and bottom with the micro lens on the light guide plate. The data of the modeling software was converted to the optical software to define the optical properties of every structure, and then compared the brightness and Uniformity of the different design of backlights. The data of simulation was as reference architecture. Second, it was created micro lens on the light guide plate by operating the inkjet printing machine in the laboratory production and packaged into 3 inch backlight module. Finally, we measured the brightness and Uniformity of sample.
