More Information
Summary:Disclosed are a driver IC and a display apparatus including the same, which supply a touch auxiliary signal, having the same phase and potential difference as those of a touch signal supplied to a touch electrode which is also used as a common electrode, to a plurality of supply lines disposed in a non-display area during a touch sensing period. The driver IC includes a common voltage supply element, a touch sensing unit, and a common voltage switching unit. The common voltage switching unit connects the common voltage supply element to a plurality of touch electrode lines connected to the plurality of touch electrodes during an image display period, and during a touch sensing period, the common voltage switching unit connects the plurality of touch electrode lines to the touch sensing unit.
