| dc.description.abstract | 近年來由於LED廣泛的應用於LCD 液晶顯示器上，使得液晶顯示器的厚度及重量有大幅度的下降，因此如何設計出更輕更薄的顯示器已經成為各家業者在初期新機種開發的時候所考量的重點之一，對於背光模組而言，主要厚度及重量決定於前框(MOLD)、背板(BACKCOVER) 、導光板(LIGHT-GUIDE-PLATE)三個主要部材，而前框及背板在厚度及重量上遠小於導光板，因此薄化導光板是降低厚度及重量最有效的方法，在這樣的思維下，現有平板、楔型板導光板的設計已無法滿足更輕更薄的市場需求，因此便催生了喇叭口導光板的設計．
本論文利用LIGHTTOOLS光學模擬軟體，搭配田口設計實驗，並利用光線追跡方式進行導光板網點最佳化模擬後，確認不同厚度、斜度光學輝度以及目視效果表現，來定義出較佳的喇叭口導光板外型設計法則，以方便背光設計者可在最短時間決定出最佳的喇叭口導光板設計，來達到減少導光板重量約20%以及節省導光板單體19%的價格並具有加速機種開發以及降低模具開發費用等附加效益。

| dc.description.abstract | The liquid-crystal-display’s thickness and weight have great reduction because that light-emitting-diodes extensive applying to LCD in recent years. How to design a thinner and lighter display is the key point of each panel’s vender in the early time of the new models developed. The mold and back cover and LGP are the three main parts that cause thickness and weight in back-light-module but the mold and back cover is thinner and lighter than LGP. So it is effectively way to reduce the thickness and weight of LGP. It can’t be satisfied in thinner and lighter in market by normal LGP design so that the Trumpet-shaped light-guide-plate has been designed.
This paper to use LIGHTTOOLS optical simulation software, with the Taguchi design of experiments and use of ray tracing the simulation of the LGP network optimization, recognition of a different thickness, the slope of the optical brightness and visual effects performance, to define better the Trumpet-shaped light-guide-plate form factor design rules, to facilitate the backlight designers determined in the shortest possible time the best Trumpet-shaped light-guide-plate design to achieve reduce LGP weight of about 20 percent and save 19% of the price of the light guide plate monomer and has to accelerate the kinds of development and reduce mold development costs and other additional benefits
