Siemens reports the flexible mini screens work using “electrochromic substances” that change their colour when an electrical charge is administered, absorbing other light wavelengths than in their original state. The company expects to achieve its goal of printing the display with appropriate select electronics included, in a printing process using semi conducting plastics.
Scientists at Siemens Corporate Technology and Siemens Automation and Drives are working to optimise the process and its composite materials, so that they react quickly enough to display realistic moving images. Select partners of Siemens are already working to integrate the displays into packaging and the manufacturing process.
The displays are expected to be used in conjunction with printable batteries which are already available and because they are only expected to be required to function for a few months in FMCG packaging, labels, tickets and other time-limited applications, the entire multimedia screen can be incorporated into cardboard, foil, plastic or paper.
