Systems and methods are provided for detecting gestures using both mutual capacitance and self capacitance touch sensing. These systems may be incorporated into devices utilizing an in-cell touch system, where the display controller is also used to drive the transmitter lines for mutual capacitance scans. The receiver lines can be used in conjunction with the transmitter lines for mutual capacitance sensing, or can be used alone for self capacitance sensing, even when the display controller is not operating, such as when the display is turned off. One-dimensional touch detection using the receiver lines alone can be used to generate different types of gesture inputs or to trigger body proximity sensing.
