Dual-loop display sensing for compensation

An electronic device comprising:

• a display including:
• one or more pixels configured to:
• in a display mode, display images;
• and
• in a pixel sense mode, provide operational information about operation of the one or more pixels;
• and
• sensing driving circuitry that drives sensing of the one or more pixels of the display during the pixel sense mode;
• and
• at least one processor configured to:
• cause the sensing driving circuitry to scan at least a portion of the one or more pixels to receive sensed data;
• store a coarser version of the sensed data in a first memory location;
• determine if a slow loop threshold period has elapsed since a last previous slow scan;
• if the slow loop threshold period has elapsed since a last previous slow scan, store the sensed data in a second memory location;
• compensate image data using the coarser version of the sensed data and the sensed data in the second memory location;
• and
• cause the display to display the compensated data.
