Joan displays utilize E-ink technology, which consumes power primarily when updating content. Once an image is shown, energy use remains minimal, making these displays significantly more power-efficient than many traditional LCD options. This efficiency can support extended battery operation, often lasting several months on a single charge.
With a display quality that closely resembles paper, Joan displays may be easier on the eyes than backlit LCD screens. As E-ink displays do not emit their own light, they help limit light pollution in shared spaces.
Joan displays are designed using recyclable materials, including aluminum and glass, and feature a slim profile. Their low power requirements and wireless capabilities enable installation in a variety of spaces, even where wired infrastructure is not available.
E-ink displays are not optimized for presenting full-color graphics or playing video content, as their color range and refresh rates are more limited. For use cases that require vibrant imagery or dynamic multimedia—such as real-time video or richly colored presentations—LCD screens generally provide a more suitable solution.
