Switch leakage compensation for global illumination

A display system comprising:

• a display including a plurality of light sources and corresponding light source driving circuits, the plurality of light sources arranged in a plurality of rows;
• a display driver circuit coupled to the display;
• and
• an application processor coupled to the display driver circuit and configured to:
• obtain position data for at least one of a head or an eye of a user of the display system;
• render, based on the position data, image data for an image frame;
• modify pixel values for each row of pixels of the image data for the image frame based on a time delay between a loading time of the row of pixels of the image data for the image frame and a time of a global illumination of the image frame, and using a pre-determined leakage current of a transistor of a driving circuit for a pixel in the row of, to compensate for leakage associated with the global illumination of the image frame by the display, wherein the pre-determined leakage current is a predicted leakage current between a drain and a source of the transistor of the driving circuit determined according to a voltage on a gate of the transistor and a voltage between the source and the drain of the transistor;
• and
• send the image data to the display driver circuit for displaying the image frame on the display through the global illumination.

A non-transitory machine-readable storage medium including instructions stored thereon, the instructions, when executed by one or more processors, cause the one or more processors to perform operations including:

• obtaining position data for at least one of a head or an eye of a user of a display system;
• rendering, based on the position data, image data for an image frame;
• modifying pixel values for each row of pixels of the image data for the image frame based on a time delay between a loading time of the row of pixels of the image data for the image frame and a time of a global illumination of the image frame, and using a pre-determined leakage current of a transistor of a driving circuit for a pixel in the row of pixels, to compensate for leakage associated with the global illumination of the image frame by a display of the display system, wherein the pre-determined leakage current is a predicted leakage current between a drain and a source of the transistor of the driving circuit determined according to a voltage on a gate of the transistor and a voltage between the source and the drain of the transistor;
• and
• sending the image data to a display driver circuit of the display system for displaying the image frame on the display through the global illumination.
