#89047 - Big sign Responding to: ???'s previous message |
The biggest LED sign ive seen is the one in Timesquare in Newyork,I dunno how many LEDs there are but it uses internal ethernet to transfer the video data to each section and has multiple remote processors to monitor voltage and temperature for each section.I should think that there are least a million LEDs each one putting out maybe 100 mW so I should think its gets a little warm in there. |
