A spherical LED screen shown at the Expo 2010 Shanghai China

A spherical screen made with one million LEDs is shown at the Expo 2010 Shanghai China. It’s designed and manufactured by Opto Tech Corp, a business partner of Nichia Corp.

The diameter and weight of the screen are 16m and 130t. And Taiwan's natural environment and cultures are displayed on it.

Opto Tech made rod-like LED modules by using Nichia's so-called "3-in-1" LEDs. 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.

Opto Tech 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.
