Fully printed via conventional printing processes, paper thin, flexible and at lowest costs - that's the new development of prelonic technologies.
Printed functional elements like batteries and displays have been under development for years now. But the area of printed electronics is still waiting for the commercial success of the technology. New developments seem to shift the technology to a new application level. Packaging and magazine applications till now focused on eye-catchers. To be able to move from eye catcher applications to information transfer and interactivity in newspapers, magazines and on packaging, simple and cheap displays are necessary - which always have been promised by display developers.
prelonic now presents its recent development, which seems to meet these requirements: a simple electrochromic display at lowest costs - but processes which are robust enough to be run in normal paper and carton printing fabs.
"For high volume Printed Electronics always a cost level of below 1 Cent/sqcm was mentioned - that is part of the attraction of printing electronics: to get electronics at printing costs. But nearly all elements and devices presented till now are far above this level. That is one of the biggest problems of Printed Electronics," Friedrich Eibensteiner, CEO of prelonic, commented on the present status of printed electronics, especially of printed displays.
Some requirements have to be satisfied by such displays: first, they should be cheap - for mass application; the production technology should fit to conventional magazine and packaging printing, no clean-room and no special printing technologies; those displays should be printable directly on transparent polymer films but also on paper without the need of additional substrates.
"Our new displays are not only cheap, but could be produced in normal printing processes, in paper and carton environment - that means dusty atmosphere. Additionally they could be bottom and top indicative - what allows us to print it directly on paper or carton." Friedrich Eibensteiner explains the main advantages.
As stated by Friedrich Eibensteiner, the work of the next few months will be dedicated to optimization and characterization tasks. Especially the top indicative display will be improved in resolution and bi-stability.
prelonic technologies is developing integrated printed electronics products. The focus is on integration of different printed electronic elements via printing. The utilized printing technology is screen printing, but also gravure and flexo printing could be used. Such products are paper-thin, flexible, cheap and could be customized to every form and application.
