Abstract: An apparatus comprises a display screen, and an optical sensor module which is disposed behind the display screen. The optical sensor module further comprises a light emitter operable to generate light having a wavelength for transmission through the display screen toward a target object. A light sensor is operable to sense light reflected by the target object and having the wavelength. A reducer is arranged for reducing the optical power density by increasing a diameter of a light beam generated by the light emitter on the display screen, wherein the reducer is disposed between the light emitter and the display screen so as to intersect the light beam generated by the light emitter.
