MJ4 P44 successfully used for 2014 Brazil World Cup Opening & Closing Ceremony, with total area 140 sqm, ball’s diameter of 7 m, and the ball will be divided into 9 petals when displaying. All petals are covered by MJ4 P44 led dots and strings. Distinctive features and specificity for the ball are as below:
1. High programmability: Ball is irregular, each string’s length are different. Even on the turning of upper and lower strings, the pixel pitches are different, thus all the strings have different resolution, length and pixel pitch.
2. Special system connection: based on the ball structure, the mapping of led dots on ball is very irregular, thus engineers made the system connection by very detailed and exact calculation.
3. Special system controlling: adopting YDEA C3.0 mark system, we use software to map the led dots on each petal and the whole ball, then all are easily controlled.
4. Special videos: engineers offered clients the coordinates for each petal and the whole ball, so that they can make the video based on the coordinates. Video on computer is separate as 9 petals on pc, but software ensures the video to show as an entire ball in reality.
5. Special installation: World Cup LED Ball removed the plastic base for MJ4 P44, but use velcro to fix the strings on the ball. Customers in Brazil covered all petals with female velcro, and we cover male velcro on backside of strings, then to keep the installation reliable.
All processing like manufacturing led strings, sticking velcro, etc, are doing one by one by hands, even we tested different brands of velcros and 3M glues to ensure high stability for long time fixing. Our engineer flied to Brazil for onsite supporting of installation, testing, maintenance, and main operation during Opening Ceremony. After primary testing, Brazil satisfied with the ball’s great performance, speaking highly about our design and work. Finally, the big led ball will be open and closed during Opening & Closing ceremony. Famous players, singers will be standing inside for wonderful shows, like Jennifer Lopez, etc.
Finally, the huge LED ball, which resembled a peeled melon after it opened up, commenced the ceremony
with a multilingual welcome message for the spectators and the viewers across the globe. At the same time,
Jennifer Lopez sang the theme song inside, offering the following exciting game season !
