Mitigating Display Diffraction Flares for Under-Display Sensing - A simplified explanation of the abstract

This abstract first appeared for US patent application 18535693 titled 'Mitigating Display Diffraction Flares for Under-Display Sensing

Simplified Explanation

The document describes systems and techniques for mitigating display diffraction flares for under-display sensing. An equation is derived to model the effects of a display in producing diffraction at an image plane of a sensing region for an under-display light-sensing device. The equation helps determine an optimized arrangement of components within the display to minimize diffraction efficiency and reduce optical artifacts in light-sensing data.

Original Abstract Submitted

This document describes systems and techniques directed at mitigating display diffraction flares for under-display sensing. In aspects, an equation may be derived that models the effects of a display in producing a diffraction phenomenon at an image plane of a sensing region for an under-display light-sensing device. The equation may be used to determine an arrangement (e.g., an optimized arrangement) of components (e.g., sub-pixels) within the display that minimizes a diffraction efficiency for at least one diffraction order and, thereby, mitigates an intensity and/or a prevalence of optical artifacts in light-sensing data. In implementations, an image intensity point-spread-function is utilized to calculate diffraction efficiencies for respective diffraction orders (e.g., the lowest diffraction orders, the diffraction orders with the greatest brightness).
