A high directional backlight system that combined a composite microstructure light guide plate (LGP) with a collimated light source was proposed for eco-displays. The collimated planar light was expanded from a point light source and guided towards the normal direction by utilizing the micro-prism array on LGP. High uniformity of spatial luminous, 91%, with a narrow viewing cone of ± 4° can be achieved without additional optical films. Moreover, compared to the conventional backlight, only 5% of power consumption was needed to keep the same luminance, hence, the optical efficiency increased by a factor of 1.47.
一种将复合微结构导光板（LGP）与准直光源相结合的高定向背光源系统被提出用于生态显示器。准直平面光从点光源扩展而来，并通过利用导光板上的微棱镜阵列导向法线方向。无需额外的光学膜即可实现91%的高空间发光均匀性以及±4°的窄视角。此外，与传统背光源相比，保持相同亮度仅需5%的功耗，因此，光学效率提高了1.47倍。
