We report a novel full-color display based on the generation of full-color by a highly efficient blue QD-LED light approach, or so called color-by-blue QD-LED display. This newly proposed color-by-blue QD-LED display combines a blue CdZnS/ZnS QD-LED blue subpixel and excitation source with front-emitting green/red phosphor subpixels. It is carefully estimated that the detailed display characteristics as well as full color-conversion and reasonable device efficiency of blue, green, and red satisfy the minimum requirements for display application. Also, we would like to emphasize that the proposed blue, green, and red device shows maximum luminance of 1570, 12920, and 3120 cd/m², respectively, luminous efficiency of 1.5, 12.1, and 2.5 cd/A, respectively, and external quantum efficiency of 6.8, 2.8, and 2.0%, respectively. It is expected that full color generation by color-by-blue QD-LED will lead to further technological advancements in the area of efficient and facile display applications.
我们报道了一种基于高效蓝色量子点发光二极管（QD-LED）光生成全色的新型全彩显示器，即所谓的蓝光量子点发光二极管彩色显示器。这种新提出的蓝光量子点发光二极管彩色显示器将蓝色硫化镉锌/硫化锌量子点发光二极管蓝色子像素和激发源与前发射绿色/红色磷光体子像素相结合。据仔细估算，蓝色、绿色和红色的详细显示特性以及全色转换和合理的器件效率满足显示应用的最低要求。此外，我们想强调的是，所提出的蓝色、绿色和红色器件的最大亮度分别为1570、12920和3120 cd/m²，发光效率分别为1.5、12.1和2.5 cd/A，外量子效率分别为6.8、2.8和2.0%。预计蓝光量子点发光二极管产生全色将在高效便捷的显示应用领域带来进一步的技术进步。
