The Phillies are installing a $10-million HD display at Citizens Bank Park.
It will be 76 feet high by 97 feet wide, the largest in the National League and one of the largest in the world.
It's two and a half times the area of the old videoboard.
The Phillies partnered with Sony Electronics' System Solutions Group and Daktronics in the development of the board.
"We're truly excited to bring the HD experience to our fans," said Mark DiNardo, Director, Broadcasting and Video Services. "The new technology and dramatically larger image will bring our fans closer to the action than ever. Our unique partnership with Sony and Daktronics gives us the opportunity to transition the in-house broadcast, production and entertainment systems to high-definition in one step."
Other locations in Citizens Bank Park that will be part of the upgrade to HD include PhanaVision (Phillies video replay and control room) and video production/video coaching production areas, as well as the facility's cable TV system.
Construction has already begun with the removal of the original Phillies videoboard, which has recently been relocated to the team's spring training facility at Bright House Field in Clearwater, Fla.
Additionally, the Phillies will be installing a dedicated closed captioning display to assist hearing impaired fans, and all 800 televisions in the suites and public areas will also be upgraded to HD.
The first opportunity for fans to see the new videoboard in action will be during the On-Deck Series, when the Phillies take on the Pittsburgh Pirates, March 29-30.
