E-paper passenger information systems developer Papercast announced enhancements to its range of solar powered e-paper displays. The main new feature is a higher refresh rate - which now can be up to 7.5 fps - which Papercast says significantly exceeds the limitations of other e-paper technology in this sector.

Papercast displays use the compayn's own proprietary e-paper driver board and heavyweight processing power, which enables the new fast refresh rate. Other recent enhancements include an ultra-low power battery operation mode when solar power is unavailable, text-to-speech support and more.
