Display-to-touch noise compensation system utilizing display data

A method for noise compensation, comprising:

• obtaining, by a processing system, display data comprising first display data for updating a plurality of subpixels of a display during a first display update period, wherein each row of subpixels of the display is associated with a respective gate line and each column of subpixels of the display is associated with a respective data line:
• determining, by the processing system, based on the first display data, estimated noise compensation data for the plurality of subpixels for the first display update period, wherein determining the estimated noise compensation data for the plurality of subpixels for the first display update period includes:
• determining a first output for a first respective subpixel of the plurality of subpixels corresponding to a time period before the first display update period;
• determining a second output for a second respective subpixel of the plurality of subpixels corresponding to the first display update period, wherein the first respective subpixel and the second respective subpixel are located in the same column and adjacent rows;
• calculating, based on the first output and the second output, an output change for the first respective subpixel of the plurality of subpixels corresponding to the first display update period;
• and
• for each row of subpixels corresponding to the first display update period, summating output changes corresponding to all columns of subpixels corresponding to the first display update period;
• and
• applying, by the processing system, the estimated noise compensation data to touch data obtained during the first display update period to mitigate an effect of display-to-touch noise on the touch data obtained during the first display update period.

A non-transitory computer-readable medium, having computer-executable instructions stored thereon for noise compensation, wherein the computer-executable instructions, when executed, facilitate performance of the following:

• obtaining display data comprising first display data for updating a plurality of subpixels of a display during a first display update period, wherein each row of subpixels of the display is associated with a respective gate line and each column of subpixels of the display is associated with a respective data line;
• determining, based on the first display data, estimated noise compensation data for the plurality of subpixels for the first display update period, wherein determining the estimated noise compensation data for the plurality of subpixels for the first display update period includes:
• determining a first output for a first respective subpixel of the plurality of subpixels corresponding to a time period before the first display update period;
• determining a second output for a second respective subpixel of the plurality of subpixels corresponding to the first display update period, wherein the first respective subpixel and the second respective subpixel are located in the same column and adjacent rows;
• calculating, based on the first output and the second output, an output change for the first respective subpixel of the plurality of subpixels corresponding to the first display update period;
• and
• for each row of subpixels corresponding to the first display update period, summating output changes corresponding to all columns of subpixels corresponding to the first display update period;
• and
• applying the estimated noise compensation data to touch data obtained during the first display update period to mitigate an effect of display-to-touch noise on the touch data obtained during the first display update period.
