The $25 million includes the cost of a control room for the boards.
The end-zone video walls won't be the biggest in the NFL but will have the highest resolution, Roitman said.
Panasonic Eco Solutions North America is supplying the TV displays and has agreed to partner with the team. The West Club lounge will now be called the Panasonic Club.
Richard Ballard, vice president of sales and marketing for Panasonic Eco Solutions, said, "Much like they do at home, sports fans now want to see replays and live action."
The TV displays "bring the experience of the home to the live arena," he said.
Panasonic, for instance, is building a huge video display at Churchill Downs, home of the Kentucky Derby, so that fans can watch the horses on TV in turns, the same as those who watch the horse race at home on TV.
Panasonic also has built large video displays for the Charlotte Motor Speedway in North Carolina and is building a bigger video display at the Texas Motor Speedway.
The Eagles began the revitalization project last June. It will be completed in time for the first regular-season games this year, team officials said. Previously, the Eagles upgraded the stadium's free WiFi network in 2013 so it can accommodate 30,000 simultaneous users.
