Nanochromic displays offer versatility and cost reduction

MacDermid Autotype's Autoflex films and nanochromic inks and being used in new nanochromic integrated displays and membrane keypads.

MAPP Systems is showcasing a nanochromics membrane keypad that cuts production times, yet offers displays with the optical qualities of printed pages readable even at acute angles and with negligible power consumption. The new displays are fabricated with specialist screen printing inks and use Autoflex EBG187 film from MacDermid Autotype. This is a high-quality, UV ink-printable, hard-coated polyester film with a gloss finish that enhances the quality of the finished display, while at the same time offering outstanding resistance to scratching and chemicals.

Prior to the launch of nanochromic displays, building an integrated control panel was a highly complex operation requiring the creation of different layers incorporating each individual component, as well as the LCD displays. Furthermore, conventional LCD displays are power-hungry, so the portability of systems was inevitably compromised.

A nanochromic display relies on specialist inks containing a reflective layer that gives them a solid white background as well as integrated viologens. These are organic electrochromic molecules that change colour with the passage of very low-voltage currents, without the need for backlighting. The method has been around for a while, but suffered initially from weak coloration and long switching times; these issues have now been resolved by Ntera, the manufacturers of the nanochromic inks used by Mapp Systems.

Stephen Morse of Mapp Systems explains: "The nanochromic inks are screen printed on the film just as we would with normal screen printing inks, but thanks to this clever technology we can now achieve full integration with the overlay and therefore a massive reduction in processing times. Our work in this sector opens up new opportunities, particularly for items such as supermarket shelves displays and packaging. The merging of this ink technology with the proven optical and physical properties of the MacDermid Autotype films allows us to offer the best possible deal around."

Emma Scowen, the Marketing Manager at MacDermid Autotype, adds: "Supporting innovation has always been one of our key strengths. We positively encourage our customers to experiment with our films, and with Mapp Systems we have a tangible demonstration of the success of this synergistic approach."
