Abstract
We developed an RGB microfluidic quantum dots light-emitting diode (QLED). All emitter and luminophores were liquid materials, including liquid organic semiconductor (LOS) as a backlight and quantum dots (QDs) solutions for high-color-purity luminophores. A deep-blue LOS backlight was used to excite QDs solutions. RGB lights were achieved with narrow full width at half maximum (FWHM) of 26.2 nm (green) and 25.0 nm (red), and were close to the boundary of CIE color space. The color purity of the RGB microfluidic QLED was the highest in that of ever reported LOS based devices. The proposed device is expected to provide future flexible displays with high-color-purity.
