Abstract

We demonstrate the quantum dot (QD) hybridpatterns produced from uniformly dispersed QDs in the host matrix with the molecular order. The molecular ordering of the liquid crystalline polymer (LCP) as a host medium plays a critical role on the uniform dispersion of the QDs. The uniformity of the QD patterns and the emission intensity are found to be greatly enhanced by the molecular order compared to the conventional cases. Our emissive color display composed of the QD hybrid patterns shows the emission spectra with the color gamut extended to 87 % of the BT.2020 standard. Our approach will provide a simple and viable method of constructing the QD-based emissive display with wide color gamut in a cost-effective manner.
