New displays to catch consumer eyes

New displays to catch consumer eyes


Producers of consumer electronics and other fast-selling products hoping to attract more eyeballs to their goods should be interested in this technology: Researchers at German electronics giant, Siemens, have developed ultra-thin miniature colour displays that can be printed onto paper or foil.

The miniature colour displays can be produced at costs far below those of LCD panels. The technology could be used to show information about products or provide step-by-step instructions directly on the packaging with the press of a tiny button.

The flexible miniature displays consist of an electrochromic material that holds a pattern of electrodes. The substance changes colour when an electrical voltage shifts charges in its molecules. Siemens scientists are currently using silicon switching elements to control the device, but the aim is to use a printing process to manufacturer the entire display. They can obtain their energy from printable batteries, which are already available, according to Siemens.
