P‐105: Collimating Optical System Made by Band Pass Filter

Abstract

Collimating light source is important in AR/VR, 3D and other display products. At present, the collimating light source usually adopts micro lens, prism and so on. The structure and manufacturing process is complex. We present new research results for collimating light, which is a novel collimating LCD backlight technology using a photonic crystal and absorption type color film. There are no complex microstructures and collimating effect in the whole plane. We report progress with performance and describe methodology and results from experiment and simulation results. The angle of collimating light can be controlled in 20°.In the future, we'll optimize the structure and use this technology in the field of QDPR and privacy display.
