We just wrapped a 12x7 curved LED wall for Pack Expo, built into a custom wood structure.
Curves look simple on screen, but getting there takes patience. The structure sets the radius, and the tiles have to follow it exactly.
Real floors are never perfect
On site, conditions are never ideal. Floors aren't always level, especially with carpet, so we split the difference with shims and used brackets to push the curve out where it needed more. They are small adjustments, but on a curve every one shows up in the final image.
Test the tiles before they go up
The other big call was testing the tiles on the ground before they ever went into the structure. Finding a bad module or a missing pixel on the floor is a quick fix. Finding it after the wall is closed up is a headache. Testing first meant fewer changes once everything was built.
The gear
The wall is Unilumen UPad tiles driven by a Novastar COEX MX40. BaseTech handled the LED installation and project management.
