在传统的液晶显示器中，由于三色分离彩色滤光片阵列的阻挡工作原理，至少有三分之二的能量被浪费掉。本文利用量子点阵列实现了红、绿、蓝三色的空间分离。该量子点阵列进一步放置在传统的彩色滤光片阵列上，通过匹配相应的彩色滤光片像素，以消除蓝光串扰。在这种情况下，这种量子点有源滤色器阵列的能量效率不再取决于其几何排列和吸收特性，而是取决于量子点的量子产率。90%的Adobe RGB色域。我们的制造方法的一个优点是直接在衬底上合成QD阵列，而不需要将QD溶解到其他介质中。该技术通过提高量子点的量子产率，为在液晶显示器（LCD）中获得比传统滤色矩阵更高的分色效率提供了一种新方法。
In the traditional liquid crystal display, at least two-thirds of the energy is wasted by tricolor separation color filter array due to its blocking working principle. In this paper, a well arrangement quantum dots (QD) array, which is excited by blue back light, was fabricated to spatially separate the red-green-blue (RGB) color. This QD array is further placed onto traditional color filter array, by matching the corresponding color filter pixel, in order to eliminate the blue light cross talk. In this case, the energy efficiency of this QD active color filter array no longer depends on its geometric arrangement and absorption properties, but depends on the quantum yield of QDs. Furthermore, 90% Adobe RGB color gamut can be achieved. One advantage of our fabrication method is synthesizing the QDs array onto the substrate directly, without the requirement of dissolving the QDs into other media. This technique may provide a new method to obtain higher color separation efficiency in liquid crystal display (LCD) than the traditional color filter matrix by enhancing the quantum yield of QDs.
