Abstract
An information handling system peripheral keyboard sized to rest on an information handling display to accept key inputs has a bottom surface with a selectively opaque layer that transitions between transparent and opaque states based upon a usage scenario. For instance, the keyboard has a transparent state when placed on the display to allow light to pass through the keyboard and illuminate the keys. When removed from the display, an opaque state hides keyboard internals so as not to detract from the keyboard appearance. In one embodiment, the selectively opaque layer is an electronic ink that presents a product brand on the keyboard bottom surface when in the opaque state.
