Neutral nanoparticle-based display

摘要

We present a novel display based on the manipulation of neutral nanoparticles dispersed in an insulating liquid. The operative mechanism is based on dielectric forces and electric field-induced dipolar interactions between neutral nanoparticles, leading to compact aggregates that change the optical characteristics. Such displays can operate either in a diffusive scattering mode or in a written mode, both based on the capacity to have a compact particle storage mode. Owing to the hysteretic behaviour, low-power operation is obtained.
