Full color display fabricated by CdSe bi-color quantum dots-based white light-emitting diodes

In this study, direct bi-color CdSe quantum dots (QDs) have been successfully synthesized and used as luminescent materials to fabricate the QDs-based white light-emitting diodes (WLEDs). We demonstrate a one-pot preparation of direct bi-color CdSe QDs-based WLEDs with a high color gamut. For the application of the backlight source, CdSe QDs with a CIE coordinate of (0.34, 0.25) were mixed with 30% UV resin, which provides a color gamut of 89 and 126% in National Television Standard Committee (NTSC) and sRGB standards, respectively. We expects that full color generation by bi-color QDs-based WLED will lead to further technological advancements in the area of efficient and facile display.
