Abstract
Systems, methods, and devices described herein may mitigate pixel and touch crosstalk noise. A touch system may compensate touch scan data to reduce the noise based on an estimated amount of switching-based display-touch crosstalk (switching DTX). Using the compensated touch scan data, the touch system may determine the proximity of a capacitive object to at least one touch sense region of the electronic display with improved signal to noise ratio.
Claims20
A system comprising:
- an electronic display configured to present image data and obtain touch scan data corresponding to at least one touch sense region of the electronic display;
- image processing circuitry configured to:
- receive the image data to be presented during a touch sensing operation;
- determine an estimated display-to-touch noise due to variations of voltage on anodes of display pixels based at least in part on content of the image data;
- and
- transmit the estimated display-to-touch noise to a touch subsystem obtaining the touch scan data to enable the touch subsystem to account for the estimated display-to-touch noise.

A system comprising:
- an electronic display comprising:
- a plurality of display pixels configured to emit light to form a frame of image content;
- a touch subsystem comprising a plurality of touch receivers, the touch subsystem configured to:
- obtain touch scan data during a touch sensing operation corresponding to at least one touch receiver of the electronic display;
- and
- adjust the touch scan data based on an estimated display-to-touch noise to account for display-to-touch noise;
- and
- image processing circuitry configured to:
- receive image data to be presented during the touch sensing operation;
- determine the estimated display-to-touch noise due to variations of voltage on anodes of display pixels based at least in part on content of the image data;
- and
- transmit the estimated display-to-touch noise to the touch subsystem to compensate the touch scan data.

A method comprising:
- receiving, via image processing circuitry, image data to be presented on an electronic display by display pixels during a touch sensing operation performed by a touch subsystem;
- determining, via the image processing circuitry, an estimated display-to-touch noise generated by due to variations of voltage on anodes of the display pixels based at least in part on content of the image data;
- and
- transmitting, via the image processing circuitry, the estimated display-to-touch noise to the touch subsystem to enable the touch subsystem to account for display-to-touch noise.
