摘要：
This research proposes the concept of Light Guide Film (LGF) at the back side of Back Light Unit (BLU). This new design may induce the exterior light, and then improve the power-saving of existent BLU. Two design models are reseated: One is design for 14 inch LCD monitor of notebook computer, which might improve 21% compared to traditional one. Another is designed for 3.5 inch LCD for mobile phone display, which might improve 15% compared to traditional one.
