Polarized emitting qLEDs based on aligned quantum rods as active materials

Several applications in display technology rely on linearly polarized light. Commonly, polarized emission is obtained by combination of an unpolarized light source with a subsequent polarizer. Following this conventional approach, a significant amount of energy is lost, as the polarizer simply blocks light having the wrong polarization direction. While there are different approaches to partially recover light reflected by the polarizer, the preferred solution is a light source which directly converts electrical energy into linearly polarized light. In this contribution we present polarized emitting qLEDs based on aligned quantum rods as active materials, which are promising devices to fulfill this task.
