Abstract
Exemplary reflective display devices and components are described. The devices and components may include a microwell layer having a plurality of quantum dot wells. Each quantum dot well of the plurality of quantum dot wells includes a reflective layer lining an interior wall of the well, and a plurality of nanoparticles configured to emit a color of light. The reflective display components may also include an electrowetting layer positioned above the microwell layer. The electrowetting layer may be operable to independently adjust an intensity of light emitted from each quantum dot well of the plurality of quantum dot wells in the microwell layer. The reflective display components may further include at least one of a light guide layer positioned above or below the electrowetting layer and one or more color filters positioned above at least one of the quantum dot wells.
