An efficient non-Lambertian organic light-emitting diode using imprinted submicron-size zinc oxide pillar arrays
(AIP, 2013)We report phosphorescent organic light-emitting diodes with a substantially improved light outcoupling efficiency and a wider angular distribution through applying a layer of zinc oxide periodic nanopillar arrays by pattern ... -
Graded-host phosphorescent light-emitting diodes with high efficiency and reduced roll-off
(A I P Publishing LLC, 2012)We demonstrated graded-host phosphorescent organic light-emitting diodes with high efficiency and reduced efficiency roll-off. The emissive layer of the graded host device consists of both electron and hole transport type ... -
Graph analytics accelerators for cognitive systems
(Institute of Electrical and Electronics Engineers, 2017)Hardware accelerators are known to be performance and power efficient. This article focuses on accelerator design for graph analytics applications, which are commonly used kernels for cognitive systems. The authors propose ... -
Power-efficient positioning for visible light systems via chance constrained optimization
(IEEE, 2020)The problem of minimizing total power consumption in light-emitting diode transmitters is investigated for achieving power efficient localization in a visible light communication and positioning system. A robust power ...
