以LED作為光源的背光模組，組裝作業時，LED與導光板間存在肉眼幾乎不可見的間隙，而當著間隙增大時背光模組輝度會大幅度下降。本論文提出一新複合稜鏡微結構之LED設計，用以調整LED的發光光型，有效解決背光模組輝度隨著因LED光源與導光板間組裝間隙增大，而大幅度下降的問題。 The backlight with LED as light source, when the assembly operation, the existence gap between LED and light guide plate is almost invisible to the naked eye, and with the increase of gap will decrease backlight brightness sharply. This paper presents a new design of the LED compound prism micro-structure to adjust the LED’s emitting light pattern to resolve the sharp decrease to backlight brightness comes with increase of assembly gap between LED and light guide plate.
