    Abstract: An electronic circuit for operating with a display panel including touch sensors and fingerprint sensors is provided. The electronic circuit includes a first circuit, a second circuit, a third circuit, a first switch circuit and a control circuit. The first circuit generates display driving signals for driving the display panel. The second circuit receives fingerprint sensing signals from the fingerprint sensors. The third circuit determines a touch information according to touch sensing signals from the touch sensors. The first switch circuit includes a plurality of first switch units, each of the first switch units includes a first switch element and a second switch element. The control circuit controls the first switch circuit to transmit the display driving signals in a first time interval, controls the first switch circuit to transmit the fingerprint sensing signals in a second time interval, and controls the third circuit to receive the fingerprint sensing signals in a third time interval.

    Abstract: The disclosure provides a method for driving an OLED touch-and-display device, a driving circuit, and an OLED touch-and-display device. The method includes: dividing each display frame into at least one display period and at least one touch detection period which are alternated; during each display period, generating sequentially-shifted gate driving signals and sequentially-shifted light-emission control signals, and sequentially applying the sequentially-shifted gate driving signals to at least a part of gate driving lines, and sequentially applying the sequentially-shifted light-emission control signals to at least a part of light-emission control lines; during each touch detection period, suspending generation of sequentially-shifted gate driving signals without suspending generation of sequentially-shifted light-emission control signals; and during a period when a gate driving signal for each row of pixels is of active level, maintaining a light-emission control signal for the row of pixels at inactive level.

    Abstract: This disclosure relates to techniques for a driving apparatus including a reordering circuit and a source driving circuit. The reordering circuit can be configured to reorder a plurality of sub-pixel data of an input data string to generate a reordered data string so as to reduce a color switching number associated with a target data line. The source driving circuit can be coupled to the reordering circuit to receive the reordered data string. The source driving circuit can be configured to drive the target data line of a display panel according to the reordered data string.

    Abstract: An electronic circuit is adapted to drive a display panel having touch sensors and fingerprint sensors. The electronic circuit includes a first circuit, a second circuit, a first switch circuit and a control circuit. The first circuit processes touch sensing signals from the touch sensors. The second circuit processes fingerprint sensing signals corresponding to a fingerprint from the fingerprint sensors. The first switch circuit includes a plurality of first terminals coupled to the first circuit and the second circuit and a plurality of second terminals configurable to be coupled to the display panel. The first switch circuit couples a part of the first terminals to the second terminals in a first time interval and couples the other part of the first terminals to the second terminals in a second time interval. The touch sensing signals and the fingerprint sensing signals are inputted to the electronic circuit through the second terminals.

    Abstract: A gate on array circuit for a display device using dual-gate architecture is disclosed. The GOA circuit comprises circuitry configured to, for a first display line of the display device, generate a first gate driving signal and a second gate driving signal for driving a first gate line and a second gate line of the first display line respectively. A first time period when the first gate driving signal is in an activation state for activating the first gate line of the first display line does not overlap with a first time period when the second gate driving signal is in the activation state for activating the second gate line of the first display line.
