A color-separation system that angularly positions color LEDs to produce color separation and a lens array to focus this light onto the pixels is proposed. The LED rays from different incident angles are mapped into corresponding sub-pixel positions to efficiently display color image, which can be used to replace the absorbing color filter in the conventional liquid crystal layer. In this paper, the prototype backlight has been designed, fabricated and characterized. The measurement results of this module showed that a gain factor of transmission efficiency three times more than that of conventional color filters efficiency improvement and a larger color gamut are expected.
提出了一种分色系统，该系统通过对彩色发光二极管（LED）进行角度定位以实现颜色分离，并使用透镜阵列将此光线聚焦到像素上。来自不同入射角的LED光线被映射到相应的子像素位置，以高效显示彩色图像，这可用于替代传统液晶层中的吸收型彩色滤光片。本文已设计、制作并表征了该原型背光源。该模块的测量结果表明，其传输效率增益因子比传统彩色滤光片的效率提高了三倍，并且有望实现更大的色域。
