Abstract
A method includes detecting a touch on a touch-sensitive display, determining a time of a display update of the touch-sensitive display, and adjusting a scanning rate of scanning electrodes of the touch-sensitive display based on the time of the display update.
Claims16
A method comprising:
- beginning a scan of a touch-sensitive display, the scan including a plurality of frames in which drive electrodes are driven while signals are received from sense electrodes such that a respective drive electrode is driven in each frame while signals are received from the sense electrodes;
- in response to detecting a touch during the scan of the touch-sensitive display and prior to completion of the scan:
- determining a length of time until a next display update;
- and
- decreasing a time of remaining frames of the scan to complete the scan and report the scan prior to a time of a next display update of the touch-sensitive display,
- wherein each first frame of the scan completed prior to detecting the touch is completed in a first length of time and each second frame of the scan completed after detecting the touch is completed in a second length of time that is less than the first length of time.

A non-transitory computer-readable medium having computer-readable code executable by at least one processor of a portable electronic device to:
- begin a scan of a touch-sensitive display, the scan including a plurality of frames in which drive electrodes are driven while signals are received from sense electrodes such that a respective drive electrode is driven in each frame while signals are received from the sense electrodes;
- in response to detecting a touch during the scan of the touch-sensitive display and prior to completion of the scan:
- determine a length of time until a next display update;
- and
- decrease a time of remaining frames of the scan to complete the scan and report the scan prior to a time of a next display update of the touch-sensitive display,
- wherein each first frame of the scan completed prior to detecting the touch is completed in a first length of time and each second frame of the scan completed after detecting the touch is completed in a second length of time that is less than the first length of time.
3 more elements
An electronic device comprising:
- a touch-sensitive display;
- a controller coupled to the touch-sensitive display and configured to:
- begin a scan of a touch-sensitive display, the scan including a plurality of frames in which drive electrodes are driven while signals are received from sense electrodes such that a respective drive electrode is driven in each frame while signals are received from the sense electrodes;
- in response to detecting a touch during the scan of the touch-sensitive display and prior to completion of the scan:
- determine a length of time until a next display update;
- and
- decrease a time of remaining frames of the scan to complete the scan and report the scan prior to a time of a next display update of the touch-sensitive display,
- wherein each first frame of the scan completed prior to detecting the touch is completed in a first length of time and each second frame of the scan completed after detecting the touch is completed in a second length of time that is less than the first length of time.
