There's a big road side LED display off 95 and i believe hallandale blvd or so, you can see it if you are traveling south on 95. The further you are from the LED display the brighter it will get. For instance a business unit that measures 6 inches by 40 inches can be seen up to 200 ft or more away in bright daylight where something larger like a 12 inches by 50 inches display unit can reach over 1000 ft in distance depending on the font and letter size that the unit box will let you do. Most of them are outside LED's so they can take just about any type of weather beating. Im talking about just the amber color not the multiple light patterns used with the Empire State Building's OLEDs. They're so bright you can see them thru tinted glass. LED's will also stand up to 100,000 hours where OLED's average 20,000-40,000 hours at the moment. OLED's are deff neat, just highly costly to be used towards marketing/advertising purposes or in form of art. I know in the case of Empire state building they were projecting lots of different light patterns.
