我们分析了三种常用的液晶显示模式与蓝色LED泵浦的红色和绿色量子点（QD）背光的颜色性能和系统效率。基于所测量的量子点发射光谱，我们可以在CIE 1931和CIE 1976颜色空间中分别实现115%和140%的色域，同时保持与传统背光源相同的能量效率。接下来，我们应用多目标优化方法来细化量子点发射光谱，并找到显示系统效率和色域之间的基本权衡。该系统的光度分析还为进一步优化QD背光设计和显示系统效率提供了有用的指导。(C)2013年美国光学学会
We analyze the color performance and system efficiency of three commonly employed liquid crystal display modes with a blue LED-pumped red and green quantum dots (QDs) backlight. Based on the measured QD emission spectra, we can achieve 115% color gamut in CIE 1931 and 140% in CIE 1976 color space, while keeping the same energy efficiency as conventional backlights. Next, we apply multi-objective optimization method to refine the QD emission spectra and find a fundamental tradeoff between display system efficiency and color gamut. This systematic photometric analysis also provides useful guidelines for further optimizing QD backlight design and display system efficiency. (C) 2013 Optical Society of America
