【摘要】：为了实现量子点背光源的白平衡,将红量子点和绿量子点与油墨均匀混合,采用丝网印刷的工艺将混合后的量子点浆料印刷到导光板的下表面,作为导光板的网点,在侧边蓝光LED激发下,使红、绿量子点发光并和蓝光共同复合发光。通过调整优化量子点在混合浆料中的比例和红、绿量子点的配比最终实现白平衡。利用OLYMPUS显微镜、F-4600荧光分光光度计和SRC-200M光谱彩色亮度计对量子点网点导光板表面形貌和光学性能进行了表征和分析。实验结果表明:当量子点在混合浆料中的质量分数为7%并且红量子点和绿量子点满足1∶12时,能够实现白平衡,CIE 1931色坐标为(0.330 8,0.327 1),色温为5 588 K,在100 m A的激发电流下亮度可达4.136×10~3cd/m~2,色域为NTSC的122.4%。
[Abstract]:In order to realize the white balance of the backlight of the quantum dots, the red and green quantum dots were mixed evenly with the ink. The mixed quantum dot paste was printed to the lower surface of the light guide plate by screen printing technology, which was used as the dot of the light guide plate. Under the excitation of side blue LED, red and green quantum dots are luminescent and combined with blue light. The white balance is achieved by adjusting the proportion of quantum dots in the mixture and the ratio of red and green quantum dots. The surface morphology and optical properties of the QDs were characterized and analyzed by OLYMPUS microscope F-4600 fluorescence spectrophotometer and SRC-200M spectrometer. The experimental results show that when the mass fraction of the quantum dots in the mixed slurry is 7% and the red and green quantum dots meet 1:12, The white balance CIE 1931 color coordinate is (0.330 8? 0. 327 1), the color temperature is 5 588K, the brightness can reach 4.136 脳 10 ~ (-3) CD / m ~ (2) under the excitation current of 100mA, the color gamut is 122.4B of NTSC.
