Forum Question: How does auto-brightness work on 1st gen iPad?

This is just a matter of curiosity. The 1st gen iPad has no camera, so how does it know how light or dark it is to auto adjust the brightness of the screen? Or does that only work on iPad 2?

    There is an “ambient light sensor” built into the iPad 1. If you hold it up in direct sunlight you can see “though” the glass around the edges and find it if you like. It is there in the iPad 2, as well. It doesn’t use the camera for brightness adjustment. (I’m pretty sure)
