'''Electrofluidic display''' is a variation of an electrowetting display that place an aqueous pigment dispersion inside a tiny reservoir. The reservoir comprises less than 5-10% of the viewable pixel area and therefore the pigment is substantially hidden from view.<ref>{{cite web|title=Gamma Dynamic Technology|url=http://gammadynamics.net/technology/|publisher=Gamma Dynamics|access-date=1 April 2012|archive-url=https://web.archive.org/web/20120303154148/http://gammadynamics.net/technology/|archive-date=3 March 2012|url-status=dead|df=dmy-all}}</ref> Voltage is used to electromechanically pull the pigment out of the reservoir and spread it as a film directly behind the viewing substrate. As a result, the display takes on color and brightness similar to that of conventional pigments printed on paper. When voltage is removed liquid surface tension causes the pigment dispersion to rapidly recoil into the reservoir. The technology can potentially provide greater than 85% white state reflectance for electronic paper.<ref>{{cite journal| title = May 2009 issue of Nature Photonics| journal = Nature Photonics| date = May 2009| volume = 3| issue = 5| pages = 304| doi = 10.1038/nphoton.2009.66| last1 = Graydon| first1 = Oliver| doi-access = free}}</ref>

The core technology was invented at the Novel Devices Laboratory at the [[University of Cincinnati]] and there are working prototypes developed by collaboration with [[Sun Chemical]], [[Polymer Vision]] and Gamma Dynamics.<ref>{{Cite web|url=http://www.gammadynamics.net/|title=gammadynamics.net|website=www.gammadynamics.net|access-date=2009-04-22|archive-date=2009-05-02|archive-url=https://web.archive.org/web/20090502144448/http://www.gammadynamics.net/|url-status=live}}</ref><ref>{{cite web |url=https://www.usnews.com/articles/science/2009/05/04/make-brighter-full-color-electronic-readers--brilliant.html |title=Make Brighter, Full-Color Electronic Readers? — Brilliant! |date=2009-05-09 |work=US News }}</ref>

It has a wide margin in critical aspects such as [[brightness]], [[color saturation]] and [[Response time (technology)#Display technologies|response time]].
Because the optically active layer can be less than 15 micrometres thick, there is strong potential for [[rollable display]]s.
