One of the most distinctive features of Taiwan’s pavilion at the Expo 2010 Shanghai China is a spherical screen made with one million LEDs.
The diameter and weight of the screen are 16m and 130t, respectively. And Taiwan’s natural environment and cultures are displayed on it.
Taiwan built a pavilion for a world exposition for the first time in 40 years (since Expo ’70 in Osaka Prefecture, Japan). The Expo 2010 Shanghai China runs from May 1 to Oct 31, 2010.
The dimensions of the modules are 19 x 23 x 720-1,200mm. In the case of a module equipped with 40 LEDs (20 pixels), its power supply voltage, power consumption and illuminance are 7.5V, 11.4W and 5.8cd/m2, respectively.
they also made a tool to combine the rod-like LED modules into the spherical shape as well as a server to control the video output for the screen. The tool has a function to easily correct the position of reinforcing steel used as a base to which LED modules are attached, the company said.
