Arizona Diamondbacks to Upgrade Video System with Daktronics High Definition HD-X Technology

Daktronics (Nasdaq:DAKT) announced today it has entered into a contract with Mortenson Construction to design and manufacture one of the world’s largest true high definition video displays for the Arizona Diamondbacks, with installation scheduled for completion prior to the start of the 2008 baseball season. The new board, to be the widest in Major League Baseball, will have the capability to display two, true high-definition, 16:9 images side by side. The display will be one of only a handful of true high definition LED boards in the world and will measure approximately 136 feet high by 46 feet wide, populated with millions of red, green and blue LEDs. "The Diamondbacks and the Maricopa County Stadium District are extremely pleased to bring the latest high definition technology to Chase Field with one of the most innovative displays in major league baseball,” said Derrick Hall, President of the Diamondbacks. "Daktronics is well known in the industry for its innovation, integration and service. That type of service leads to the great amount of trust needed in our relationship and the reason we turned to Daktronics once again. With our division championship from last season, the excitement and momentum going into next year, and this investment in fan-friendly technology, D-backs fans will have a lot to cheer about.” With 880 native lines of resolution, the new display will provide high definition video in up to 4.4 trillion colors. The display will be approximately eight times larger than the existing CRT video board and will be attached to the existing structure after the original components are removed. The Daktronics HD-X technology and its control system allows for complete flexibility in programming. The board can serve as one giant display or be divided into multiple zones (windows) to show a wide variety of statistics, information, graphics, animation and video. The existing main scoreboard behind centerfield was completed in 1998 as part of the original ballpark construction and incorporates multiple components including two Daktronics incandescent lamp matrix displays and CRT (cathode ray tube) video board. Both incandescent and CRT technologies are outdated and have since been replaced with more efficient, more reliable, more vivid LED (light emitting diode) technology. In addition to the original equipment, Daktronics provided the large LED ribbon board that is mounted to the second deck of seating, running from left field to right field. Daktronics Sportsound® division updated the ballpark’s sound system in 2006. "We are pleased to continue our partnership with the Diamondbacks and the Stadium Authority,” said Robin Hall, Regional Sales Manager for Daktronics. "It is an exciting time in the sports industry, with new technologies becoming available to offer fans more excitement and entertainment value at events. Our HD-X technology has quickly become a popular choice for those venues wishing to move up to high resolution and high definition video capability.” About the Arizona Diamondbacks and Chase Field The Arizona Diamondbacks finished last season as the 2007 National League West Division Champions and 2008 marks the celebration of the organization's 10th anniversary in Major League Baseball.
