1. A method comprising:
receiving a lens focal length for an under-display light-sensing device;
determining, based on a derived image intensity point-spread-function equation adjusted for the lens focal length, a physical arrangement of components within a display panel effective to reduce a diffraction efficiency for one or more diffraction orders; and
arranging the components within the display panel based on the determined physical arrangement of components within the display panel effective to mitigate diffraction flares at an image plane of the under-display light-sensing device.
