Controllable assessment of quantum rods with polarized emission for display applications

Abstract

Semiconductor quantum rods (QRs) emit polarized light, which shows great promise in the development of modern display devices with regard to energy efficiency and color enhancement. Here we demonstrate stretching of an aligned QR polarized film for brightness enhancement and optical efficiency improvement of current quantum-dot based displays. Study of the relationship between the QR material, stretching ratio and degree of alignment provides a guide for the fabrication of highly polarized QR film. A large-area film with a high degree of alignment of 0.635 and more than 1.6-fold enhancement of brightness and transmittance compared with the traditional structure was achieved, making the film a viable candidate for use in various energy-saving display devices.
