Claim 38:
39. An integrated driving device, comprising:
a touch sensing circuit configured to perform touch sensing in a first plurality of touch sensing periods during a first frame period and in a second plurality of touch sensing periods during a second frame period, wherein the first plurality is less than the second plurality;
an optical sensing circuit configured to perform optical sensing during a third number of optical sensing periods during the first frame period to obtain optical sensing signals for generating first ambient light information,
wherein the first plurality of touch sensing periods and the third number of at least one optical sensing period are non-overlapping, and the third number of optical sensing periods are respectively located in one or more sensing periods which locations are differences between the first plurality of touch sensing periods and the second plurality of touch sensing periods.
