Mitigating Artifacts Caused by an Under-Display Light Emitter

An electronic device, comprising:

• a display comprising pixels;
• a proximity sensor comprising a light emitter that emits light through the display;
• and
• control circuitry configured to, based on operating conditions for a given display frame, modify pixel data for the given display frame to mitigate artifacts caused by the light from the light emitter passing through the display.

An electronic device, comprising:

• a display comprising pixels;
• a proximity sensor comprising a light emitter that emits light through the display;
• and
• control circuitry configured to:
• for each pixel in a subset of the pixels, determine an emitter artifact profile for that pixel using at least a brightness of that pixel for a given display frame and a look-up table;
• spatially weight the emitter artifact profiles for the subset of the pixels to obtain a single representative emitter artifact profile for the subset of the pixels;
• use the single representative emitter artifact profile to determine an optimal firing time for the light emitter in the proximity sensor;
• and
• control the light emitter to emit light at the optimal firing time during the given display frame.
