Technology directed to low-emissions touch controller in in-cell touch display systems is described. One in-cell touch controller includes a signal generator circuit that is configured to generate a sense signal according to a sensing function, the sense signal including a windowed sinusoidal waveform. The controller generates a transition signal to transition the in-cell touch display between a display function and the sensing function. The controller drives the sense signal and the transition signal on common voltage (VCOM) layer of electrodes during a touch scanning interval. During a display function interval an integrated display driver is configured to drive a first signal on the VCOM layer of electrodes during a display function interval.
