Display off-time sensing

Non-transitory, computer-readable, and tangible medium storing instructions thereon, that when executed, are configured to cause one or more processors to:

• set a first indication that a first sensing type for a display panel is to occur during an off period for the display panel, wherein the first sensing type comprises emissive element sensing;
• set a second indication that a second sensing type for the display panel is to occur during the off period for the display panel, wherein the second sensing type comprises thin film transistor sensing;
• determine whether the first sensing type and the second sensing type are to occur within a threshold time of each other;
• upon determining that the first sensing type and the second sensing type are not to occur within the threshold time of each other, perform a first sensing having the first sensing type and perform a second sensing having the second sensing type;
• and
• upon determining that the first sensing type and the second sensing type are to occur within the threshold time of each other, delay the first sensing and performing the second sensing.

A system comprising:

• a display having sensing circuitry configured to sense parameters of the display during an off state of the display, wherein sensing the display comprises sensing using emissive element sensing and sensing using thin film transistor sensing;
• a processor;
• and
• memory storing instructions that, when executed, are configured to cause the processor to:
• cause the sensing circuitry to scan the display in a frame-by-frame basis;
• determine whether a user interrupt has occurred during the scan;
• upon determination that no user interrupt has occurred during the scan:
• determine whether a frame of the scan has been completed;
• and
• upon completion of the frame, store frame data for the frame to update compensation values for driving the display;
• and
• upon determination that the user interrupt has occurred during the scan, abandon current frame data and begin the frame of the scan again at a later scanning opportunity.

A method comprising:

• sensing a display during an off state of the display, wherein sensing the display derives compensation values to compensate for non-uniformity of the display when the display is driven and wherein sensing the display comprises sensing using emissive element sensing and sensing using thin film transistor sensing;
• receiving an indication that the display is in an on state;
• predicting aging during the on state based at least in part on the sensing of the display in the off state;
• receiving an indication that the display has entered a subsequent off state;
• re-sensing during the subsequent off state to obtain re-sensing values;
• and
• adjusting prediction of aging during subsequent on states based at least in part on a difference between re-sensing values and the predicted aging.

A method comprising:

• performing active panel conditioning to reduce hysteresis in pixels of a display panel during an off state of the display panel;
• during active panel conditioning, sensing aging effects of an emissive element of the display panel;
• after active panel conditioning and the sensing aging effects of the emissive element have completed, sensing thin film transistor aging of the display panel;
• predicting aging during an on state based at least in part on the sensing of the display panel in the off state;
• receiving an indication that the display panel has entered a subsequent off state;
• re-sensing during the subsequent off state to obtain re-sensing values;
• and
• adjusting prediction of aging during subsequent on states based at least in part on a difference between re-sensing values and the predicted aging.
