Paper Abstract

A backlight unit (BLU) of TFT-LCD is composed of a light source, a light guiding plate (LGP), prism sheets, diffusive sheets and a reflective sheet. The LGP is a very important component in backlight panel (BLP). Generally, Polymethyl methacrylate (PMMA) material is chosen to make the LGP by using injection molding technique. In this research, Microelectromechanical Systems (MEMS) and hot-embossing technology are applied to fabricate the integrated LGP with the microstructures of double-sides and a reflective film. The new BLU will be only one integrated LGP without any other optical components, which are a reflective sheet, a diffusive sheet, and a prism sheet in BLU, and it can save the space and the fabrication cost. In future, the integrated LGP could make the display thinner and brighter for LCD application.
