摘要
Embodiments of the present invention generally provide a method and system for sensing interference in a display device having integrated input sensing. In various embodiments of the invention, input sensing performed on one or more rows of common electrodes may be operated for interference sensing, and, during the blanking period, some or all of the common electrodes may be operated for interference sensing. Interference measurements acquired during blanking periods may be used to increase the accuracy with which input sensing is performed, for example, by establishing one or more baseline interference values and/or determining that one or more common electrodes should be driven at a different frequency. In some embodiments, all of the common electrodes may be operated for interference sensing during a blanking period, while in other embodiments a portion of the common electrodes (e.g., one-third, one-half, etc.) may be operated for interference sensing during a blanking period.
