Technical Details
The initial display contained about 2.1 million lightbulbs controlled by 32 computers located in kiosks on the mall. The sound system, using speakers suspended over the mall, was rated at 350,000 watts. Strobe lights were added at some point to provide additional entertainment options on Disco Nights.
Displaying images that looked "real" took some innovation. New techniques were developed to make these curved, low-resolution images viewable from the ground. One adjustment was to move images slowly across the display to prevent blurring.
The 2001 upgrade to the sound system raised the power to 555,000 watts.
The 2004 upgrade features a 12.5-million LED display and more color combinations than the original display. The old control system was replaced by a central control room using 10 computers.
