Electronic paper has many advantages. First, no power is needed to maintain static images. Second, no backlighting is necessary, and it can be viewed even in direct sunlight. However, the primary benefit is that it is as legible as real paper because the characters and the figures can be clearly displayed at high resolution. These features indicate the potential of electronic paper as an ideal device if it is applied to 3D displays. Integral photography is one of the best of the various methods of 3D display because not only horizontal but also vertical parallax are obtained without having to wear special glasses. Researchers previously believed that a very expensive fly's eye lens had to be custom designed based on the size of the pixels on the display. However, the extended fractional view (EFV) method, proposed by one of the authors, changed this situation. This method has enabled us to combine a wide range of display devices and several fly's eye lenses on the market with almost no restrictions because the ratio between the lens pitch and dot pitch is no longer restricted to integer numbers. We describe a new 3D display system using electronic paper in which an existing fly's eye lens was placed on the electronic paper of an electronic book (Sony PRS505), and elemental images synthesized with the EFV method were displayed. Our experiments revealed that excellent binocular vision was possible.

  • For more than 30 years, IS&T's series of digital printing conferences have been the leading forum for discussion of advances and new directions in 2D and 3D printing technologies. A comprehensive, industry-wide conference that brings together industry and academia, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems?particularly those involved with additive manufacturing and fabrication?including bio-printing, printed electronics, page-wide, drop-on-demand, desktop and continuous ink jet, toner-based systems, and production digital printing, as well as the engineering capability, optimization, and science involved in these fields. In 2016, the conference changed its name formally to Printing for Fabrication to better reflect the content of the meeting and the evolving technology of printing.
