  • OPTICAL PROXIMITY SENSING WITH REDUCED PIXEL DISTORTION
    Publication number: 20220375432
    Abstract: A method of operating an optical proximity sensor of a computer device having a display, where the optical proximity sensor is located beneath or otherwise adjacent to the display. The method comprises obtaining a vertical synchronization signal from a display driver, and synchronizing periodic illumination of a light emitter of the optical proximity sensor with the vertical synchronization signal.

  • OPTICAL PROXIMITY SENSOR SYSTEM
    Publication number: 20220109442
    Abstract: An apparatus includes a display screen, and an optical proximity sensor module disposed behind the display screen. The optical proximity sensor module includes a light emitter operable to produce light having a wavelength for transmission through the display screen toward a target object, and a light sensor operable to sense light reflected by the target object and having the wavelength. The optical proximity sensor module can includes means for reducing a maximum energy density of a light beam produced by the light emitter. The means for reducing the maximum energy density of the light beam is disposed between the light emitter and the display screen so as to intersect the light beam produced by the light emitter. In some cases, there are multiple light emitters collectively operable to provide sufficient optical energy for proximity sensing without producing a visible spot on the display screen.
