Unfortunately there are some disadvantages to this rather revolutionary technology. E-paper technology displays have not yet made it to a stage of mass-production, which means these items may be very costly, especially for those organizations, which would require a large quantity.
E-paper is still in development, which means that those models already available may not have all the desired attributes. For example, e-paper displays are available, but most are only
monochrome; therefore photos or advertisements will lack the esthetic attractiveness desired by both the producer and consumers. Also to be noted is that since there is no backlight, e-paper has a relatively low brightness (cannot be read clearly in darkened areas), as well as low resolution, leading to distorted photos and depending on font size, blurred writing. These drawbacks defeat the purpose of the electronic document reader for employees and consumers, as well as using e-paper as a means of advertising.
E-paper has low refresh rates, which do correspond to the energy savings, however they are time consuming. The slow refresh rates also contribute to the “ghost images” which sometimes appear (burnt-in remnants from previous images displayed).
Finally, since it is a new technology, some, but not all publishers have signed on to making their products available to e-paper readers. To note is Random House (the largest American publisher).
