Abstract:
1. A method for improving the uniformity of the response time of an e-paper display for a digital reader, the method comprising providing a e-paper display which comprises fluid-containing pixels, positioning at least one sheet of compressed particles of exfoliated graphite having a density of at least about 1.1 g/cc adjacent to a plurality of pixels of the e-paper display and a heat source in thermal contact with at least some of the pixels in the plurality of pixels, such that the response time of any one of the pixels in the plurality of pixels is no more than twice that of any other pixel in the plurality of pixels, wherein the temperature difference between individual pixels of the majority of the pixels which the at least one sheet of compressed particles of exfoliated graphite is positioned adjacent to is no more than 5° C.
