P-107: Colloidal Quantum Dot LED Transparent Display on Flexible Substrate

We report Quantum Dot light-emitting diode(QD-LED) designed on transparent and flexible PEN substrate, which shows saturated red electroluminescence spectra with full-width half-maximum(FWHM) as narrow as 40nm and transmittance of 60% at 550nm. In order to make flexible and transparent device, we fabricated a set of devices through combination of various cathodes materials and substrates.
