Ntera unveils nanotechnology for printed electronics on packaging
Abstract:
Ntera has debuted a nanotechnology to mass produce electronic displays on a wide range of paper, packaging, ticket and greeting card products. The technology, which is already being market-tested in Europe, allows color displays to be ‘printed' on almost any traditional printed product at low cost and with minimal power requirements, says the company.
Working on a similar principle to how automotive mirrors are able to darken in response to light stimulus, Ntera's NCD display deploys an array of electrodes made of a metal oxide semiconductor mounted on a flexible film that reportedly allows it to produce images with a resolution equivalent to conventional inkjet print resolutions. When electrochromic molecules are attached to a film of semiconducting nanoparticles, it effectively creates a film that is several hundreds of layers of electrochromic molecules thick. A charge applied through the semiconducting particles causes the molecules at the surface to be charged and therefore to change color. Because the film is many layers of particles thick, the optical change, barely detectable in only one layer of particles, is dramatic. Adding an opaque white layer behind the electrochromic layer as background to the images makes these displays even more vivid. Like printed text on paper, NCD displays can be viewed clearly from virtually any angle and under a wide range of lighting conditions, and require only a fraction of the power of LCD displays to maintain the image.
