Abstract
An optical device includes a display and an optical sensor. The display includes display circuitry. The optical sensor is arranged behind the display. The optical sensor includes an emitter for emitting light through the display and a receiver for receiving light reflected back through the display. An absorption of the display is wavelength dependent and the absorption of the display is 50% at a first wavelength. The emitter is configured to emit light at a second wavelength greater than the first wavelength.
