7.4: A Novel Luminescent Efficiency Enhancement Strategy for a 20‐inch Carbon Nanotube Backlight Units

Abstract

In this paper, an asymmetrical dynamic model of the luminescent property of phosphors is first proposed and developed by measuring the experimental data. Then, based on the model, a novel drive strategy is derived to fully exploit the persistence effect of phosphors for a 20‐inch CNT‐BLU. It turns out that the resulting illuminative efficiency can be increased by more than 74% as compared with the most recent pulse mode driving strategy.
