    Abstract: An electronic apparatus including a display panel and a driving circuit is provided. The display panel includes a plurality of display units. Each of the display units includes a light-emitting element. The driving circuit is coupled to the display panel. The driving circuit is configured to output a scan signal and a reset signal. When a reset interval of the scan signal is transmitted in a non-display area of the display panel, the driving circuit compensates the reset signal and outputs the compensated reset signal to reset the light-emitting element.

    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: Provided are a fingerprint identification method for a panel, an electronic device and a control circuit. The method includes setting voltages on the data lines and sensing lines that may affect a fingerprint identification result to a predetermined DC voltage during a predetermined time period before a start of a fingerprint identification period that follows a display driving period. As such, when a display driving operation and a fingerprint identification operation are performed in a time-division manner, the influence of the display driving operation on the fingerprint identification operation can be eliminated, that is, the influence on the fingerprint identification result from the voltage on the data line and sensing line can be eliminated.

    Abstract: An electronic circuit adapted to drive a display panel is provided. The display panel includes touch sensors and fingerprint sensors. The electronic circuit includes a touch sensing circuit, a fingerprint sensing circuit and a display driving circuit. The touch sensing circuit senses a touch of a finger and determines a first area corresponding to the touch on the display panel. The fingerprint sensing circuit senses a fingerprint image of the finger corresponding to the first area. The display driving circuit drives pixels of the first area with respective first gray levels and pixels of a second area outside the first area with respective second gray levels. The display driving circuit processes respective third gray levels to obtain the respective second gray levels. The display driving circuit generates gamma voltages corresponding to the respective first gray levels and the respective second gray levels according to the same gamma curve.
