Display Technology
Electrochromism – to modify colour with electricity – is an exciting area used in dimmable glass; rear-view mirrors, airplanes and heat control in buildings, but also in small displays which might substitute the LCD technology, and potentially in colour-shifting surfaces.
Electrochromic display technology has been developed by RISE researchers for over a decade now. Throughout the years the electrochromic display has been incorporated in various printed systems as an indicator for biosensors, cold chain monitoring and medtech applications.
RISE researchers have adapted our reverse electrochromic displays to self-adhesive substrates in order to allow the displays to be placed on curve and other surfaces.
This research has been published with the title: All-printed Electrochromic Stickers and can be read here.
As RISE strives for more sustainable solutions for our technology, we have been developing more sustainable electrochromic displays by producing them on paper substrates instead of the usual plastic.
The recent development of sustainable display technologies can be found in the links below:
Electrochromic Displays Screen Printed on Transparent Nanocellulose-Based Substrates
Screen Printed Reflective Electrochromic Displays for Paper and Other Opaque Substrates
Paper Electronics Utilizing Screen Printing and Vapor Phase Polymerization
In order to allow individual pixel addressing without each pixel requiring its own contact pads, passive matrix address can instead be utilized in all-printed electrochromic displays.
