Now consider the fact that all it would take to wipe out these emissions would be the introduction of a small photovoltaicdevice to replace each charger - one which is flexible, durable, cheap to produce and, crucially, works in ambient (indoor) light.
The UCLA Engineering team created a new type of energy-harvesting polarizer for LCDs called a polarizing organic photovoltaic, which can potentially boost the function of an LCD by working simultaneously as a polarizer, a photovoltaicdevice and an ambient light or sunlight photovoltaic panel.
