  • Patent number: 11922844
    Abstract: An integrated driving device is provided. The integrated driving device includes a touch sensing circuit and an optical sensing circuit. The touch sensing circuit is configured to perform touch sensing in a plurality of touch sensing periods during a first frame period. The optical sensing circuit is configured to perform optical sensing during at least one optical sensing period during the first frame period to obtain optical sensing signals for generating first ambient light information. The touch sensing periods and the optical sensing period are non-overlapping. Correspondingly, an operation method of an integrated driving device is also provided.
