We proposed a novel backlight system, which consisted of a hybrid light guide plate (LGP) and one diffuser sheet. The hybrid LGP contains a flat plate without any microstructures and one layer of optically patterned film (OPF). Comparing with the conventional edge-lit backlight system, the on-axis luminance could be improved to 6.1 × by using the(More)
This paper describes an innovative approach for fabricating seamless roller molds based on conventional photolithography. The fabricated seamless roller molds are then applied in a UV-curing roller imprinting process to replicate ball-lens-array microstructures on a polymer substrate, which finally forms a light-converging optical film to be used in(More)
Light-guide plates (LGPs) with aperiodic or size-varied microstructures are widely used in edge-lit light-source backlight systems for their high uniformity. In this Letter we designed a LGP with periodic and single-sized microstructures and analyzed the relationship between the holistic arrangement density of the microstructures and the uniformity.
