A new 1,000′ (305 m) LED display system has been powered on along the road leading to Denver’s international airport (and discussed by Panasonic at CES this year Panasonic still in CE – If not in US TV). The sign was installed and will be maintained by Panasonic, which has a strong relationship with the city, and is said to have cost $15 million in total with an expected 16 year payback period. It consists of 16′ (4.8m) columns of LEDs on individual poles with full pixel addressable displays.
There is a video below that shows the way that the display works.
