Integrated driving device and operation method thereof

An integrated driving device, comprising:

• a first sensing circuit, configured to perform touch sensing in a plurality of first touch sensing periods in a first frame period;
• a display driving circuit, configured to output data voltages in a plurality of display periods in the first frame period;
• and
• a second sensing circuit, configured to perform ambient light sensing during a porch interval in the first frame period to obtain an ambient light sensing signal, wherein outputting the data voltages is being stopped in the porch interval;
• and
• wherein the first sensing circuit is further configured to perform another touch sensing in a plurality of second touch sensing periods in a third frame period in which the display driving circuit of the integrated driving device is operated in a power saving mode,
• wherein the second sensing circuit is further configured to perform another ambient light sensing in a plurality of ambient light sensing periods in the third frame period,
• wherein under the power saving mode, the plurality of ambient light sensing periods are separated by at least some of the second touch sensing periods.
