Can't help with the specific requirements, but im working in a german company (scheduled operation) that hasn't used paper charts for more than 10 years. First we used windows based tablet PCs, and for the last three years we use iPads. All certified with the LBA and i guess therefore according to EASA rules, although the LBA does not have a good track record in complying with EASA regulations.
Nowadays the only paper we carry is the QRH and the Techlog, the rest is done electronically, either via the iPad or ACARS. The latter is used for the journey log. And even the QRH is on its way out.
