| WGBH's Digital Mural |
Commuters coming to Boston on the Massachusetts Turnpike now have a new landmark: a large LED digital mural outside WGBH's new studio complex in Brighton. Every day, 6:30am–7pm, the digital mural features a new image or series of images drawn largely from that day's TV or radio programming on WGBH or from other sources of content that reflect WGBH's mission. At night, the mural displays a tranquil image of the evening sky over Boston as seen from the west. |

| About the Technology |
Embedded in the building's exterior wall, the approximately 30-foot-by-45-foot display of light-emitting diode (LED) panels is visible to eastbound MassPike travelers from approximately a mile and a half away.
WGBH's digital mural employs the same LED technology used by many large-screen displays. Light-emitting diodes are tiny devices about the size of a grain of rice that emit a very bright light in three colors: red, blue, and green, arranged in red/blue/green clusters about every inch. By modulating the current to each diode — much like a TV image — a full range of millions of colors can be created. Unlike a TV screen, however, LED screens are only a few centimeters deep; they are also much brighter than a TV screen, providing greater visibility in direct sunlight.
