E-Ink displays might be the popular technology for eBook readers at the moment, but a new type of display demonstrated at the University of Cincinnati might be able to challenge it, as it uses a different substrate for the pigment used to create black areas on the display – oil. This apparently results in less resistance for the pigment and a faster refresh rate of 20ms, allowing for the possibility of video and animations being displayed. Aside from the refresh rate, the non-black portions of the display are also more reflective than current E-Ink displays, reflecting 75 percent of the light as opposed to 40 percent, resulting in an increase in brightness and contrast, making it more like regular paper. Will we be seeing such displays used in eBook readers of the future?
