1. A display, comprising: a substrate; a light source disposed at a first location of the substrate; a light sensor disposed at a second location of the substrate; and a first optical medium disposed on the substrate over the light source, the first optical medium including a surface oriented such that light from the light source is incident at the surface at an angle greater than a critical angle for total internal reflection, thereby preventing light from the light source from passing through the first optical medium and into the light sensor.
