The current smart windows based on polymer dispersed liquid-crystal (PDLC) and electrochromes are still not cheap enough for household applications. A flat glass is clear while a frosted glass with microrough surface appears translucent by light scattering. Motivated by this optical surface scatterer, we developed an active smart window based on a soft capacitor with voltage-tunable surface roughness. This active smart window switches between clear and frosted (from 80 to 1% in-line transmittanc...

The global trend is towards sustainbility. This is a patented technology uniquely launched from IPHatch platform.  Eco E-paper focuses on a technique that can improve display performance and shows high definition in display density. Eco E-paper is important in a way where various modifications can be made to it. It is capable of increasing the size (from A5 size to more than 100cm in length and less than 50cm in width) with flexiblity added to it.

Solution processed perovskite is a new-generation thin film technology with solution inks for photovoltaics (PV) and light emitting diode (LED), suitable for application using printing and coating techniques. The world record efficiency of PV lies between silicon solar cell (first generation PV, 26.7%) and thin film solar cell (second generation, ~22%). The luminescent properties, i.e. colour tunability and external quantum efficiency (EQE), of perovskite-based LED are comparable to those of OLE...
