Paper Abstract

LED play the role at such the kind of modern display light source thanks to its power consumption and the most important, outstanding colour gamut. Modern displays are required to be much thinner and thinner with best colour gamut. We have manipulated the pattern distribution of the micro features to obtain the required optical characteristics. A light guide plate (LGP) of 3.5 inch dimension using an LED light source is used as an example for the study of integrated LGPs. This research designs a piece of light guide film (LGF) at the back of LGP. It may induct the exterior light, and enables the backlight module to achieve the energy conservation. In addition, the special-designed light pipe and freeform optics will induce external light, which will contribute 15% power savings.
