Abstract: A driving apparatus and an operation method thereof are provided. The driving apparatus includes a first driving circuit and a second driving circuit. The first driving circuit suspends performing at least one of a display driving operation and a touch sensing operation during a skip period under a driving mode, and the first driving circuit performs the at least one of the display driving operation and the touch sensing operation outside the skip period under the driving mode. The second driving circuit is coupled to the first driving circuit. The second driving circuit performs a fingerprint sensing operation during the skip period.

Abstract: A driving apparatus and an operation method thereof are provided. The driving apparatus includes a first driving circuit and a second driving circuit. The first driving circuit performs a first driving mode on a panel. The first driving circuit performs the first driving mode during a first frame period among a plurality of frame periods and skips the first driving mode during a first skip period between the first frame period and a second frame period among the frame periods. The first driving circuit outputs timing control signal including a timing that the first driving mode is skipped. The second driving circuit is coupled to the first driving circuit to receive the timing control signal. The second driving circuit performs a fingerprint sensing operation different from the first driving mode on the panel according to the timing control signal during the first skip period.
