Etulipa’s Electro Wetting Display

No light pollution

As with paper, lighting is usually only required during the evening; during the day the ambient light is most often sufficient to read text and see images.

An Electro Wetting Display creates almost zero light pollution and is therefore not intrusive, unlike the more common LED displays. And when LED-displays are not allowed, an EWD can usually get a permit! This opens up new possibilities for Outdoor advertising in residential areas where LED displays are prohibited.

Grid-independent

The pixels do not generate light – which consumes a lot of energy – but instead reflect sunlight, just like paper. There are no lightbulbs or LEDs involved. That makes an Electro Wetting Display so ultra-low power that it can work completely off-grid using just a solar panel and a battery. That is ideal in circumstances where electricity is not available or expensive to apply. For instance, in big cities the wiring, pipes, and utilities below city concrete is similar to that of spaghetti, hence making it a challenge for installers to find a sweet spot to dig without interfering in other services.
