In this paper, we got wide color gamut of quantum dot (QD) films by optimizing the spectra width and optical density (OD) of quantum dots. The specific methods to achieve the following: QD R: one layer of color filter R film was coated below the QD R layer. QD G: one layer of yellow‐green film was coated below the QD G film. By a structure optimal design, we got wide color gamut up to 99.2% BT2020 (equal to 132.86% NTSC) in Cd‐based QD and 93.6% BT2020 (equal to 125.35% NTSC) in Cd‐free QD. Furthermore, the gamut of QD display will continue to be improved by continuous refining the structure of QD display.

通过优化最大宽度一半的全宽度和蓝光的光密度，从量子点发出高色纯度的光

通过优化量子点的光谱宽度和光密度（OD），我们获得了量子点（QD）薄膜的宽色域。实现以下目的的具体方法：QD R：在QD R层下面涂覆一层滤色器R膜。QD G：在QD G膜下面涂一层黄绿色膜。通过结构优化设计，我们在基于Cd的量子点中获得了高达99.2％的BT2020（相当于132.86％NTSC）和在没有Cd的量子点中达到了93.6％的BT2020（相当于125.35％NTSC）。此外，通过连续改进QD显示器的结构，将继续改善QD显示器的色域。
