Abstract：

The　quantum-dots　(QDs)　light　guide　plate　(LGP)　was　prepared　with　red　quantum　dots　(R-QDs),　green　quantum　dots　(G-QDs)　and　ink　on　the　surface　of　PMMA　by　screen　printing.　The　red　and　green　light　emitted　from　R-QDs　and　G-QDs　which　were　excited　by　the　side　blue　LED.　The　white　light　was　achieved　by　adjusting　the　proportion　of　the　QDs　in　the　mixture　and　optimizing　the　ratio　of　R-QDs　and　G-QDs.　The　morphology　was　characterized　by　OLYMPUS　microscope.　The　LGP　optical　properties　were　investigated　by　F-4600　fluorescence　spectrophotometer　and　SRC-200M　spectrum　color　luminance　meter.　The　results　showed　that　white　light　could　be　achieved　when　the　QDs　was　7%　in　the　mixture　and　the　ratio　of　R-QDs/G-QDs　was　1:12,　which　showed　the　CIE　1931　color　coordinates　of　(0.330　8,　0.327　1),　CCT　of　5　588　K,　brightness　of　4　136　cd/m2,　and　a　color　gamut　of　122.4%　NTSC.　©　2017,　Science　Press.　All　right　reserved.
