Project Information

  

Pitch - 25mm, 1R1G1B. Compared with other LED displays installed nearby the most prosperous business center in Shenzhen, Yaham provided the optimum solution with the biggest pixel pitch 25mm, 1 red, 1 green, 1 blue only (3 Nichia high brightness LEDs) for 1 pixel that the cost could be down to the most and still high quality. Meanwhile, the viewing distance has been considered very well. As you know, the pitch is bigger, the unit price will be less and the main viewing distance would be longer.

  

Display Time - working 14 hours daily. Since done in June 2007, the 184 sqm panel displays 14 hours daily for media advertising with log for end advertising customer that they can find how long their ads have been displayed respectively.

  

Color Revivification - Through Yaham patent control system, the video have been revivified truely on the screen in 1,024 gray scale per color (red, green, bule) so that every passby audience could feel the best vision effect. The pictures showed here were taken at different time, some was in 2007, some was in 2008, the first picture was in Mar 2009.

 

Cabinet & Screen Structure - arc, central angle 106 deg. Yaham designed an arc LED display for this project base on the building condition. Though the central angle is 106 degree and radius is 5.2 meters, you may see all the cabinets have been designed and installed without any inconvenience for vision. When we design the whole screen structure, we refered to the building structure drawing; considered the wind load factor, rainy weather, etc...

   The whole screen is 20 meters above the ground.
