摘要： A method for touch sensing enhancement implemented in a single chip, a single chip capable of achieving touch sensing enhancement, and a computing apparatus are introduced. The single chip is used to be coupled to a display panel with a touch sensor and a fingerprint sensor. The computing apparatus may include the display panel, the single chip, and a processing unit, wherein the single chip is coupled between the display panel and processing unit. The method includes obtaining touch sensing data by a touch sensing module disposed within the single chip and coupled to the touch sensor; obtaining fingerprint sensing data by a fingerprint sensing module disposed within the single chip and coupled to the fingerprint sensor; and generating output touch data based on the touch sensing data and the fingerprint sensing data. With the contribution of the fingerprint sensing data, touch sensing enhancement can be achieved.

摘要： A touch panel module including a touch panel area and a non-touch panel area is provided. The touch panel module includes a touch panel. The touch panel is located in the touch panel area. The touch panel senses a touch gesture by using a plurality of first and second sensing electrodes. At least one part of the first sensing electrodes is located in the non-touch panel area. Another one part of the first sensing electrodes and a whole of the second sensing electrodes are located in the touch panel area. The touch gesture touches the touch panel module to generate a touch area. A touch position corresponding to the touch gesture on the touch panel is determined based on a ratio of an area of the first sensing electrodes touched by the touch gesture and the touch area.

摘要： An electronic circuit, adapted to drive a display panel comprising touch sensors, is provided. The electronic circuit can include a display driving circuit, a timing circuit and a touch scan circuit. The display driving circuit drives a touch display panel. The timing circuit receives a flag signal from a processing circuit and generates a scan start signal according to the flag signal. The touch scan circuit generates a plurality of touch scan signals according to the scan start signal and a touch column synchronization signal. The touch scan circuit determines a start time of a touch frame period according to a pulse of the scan start signal. The scan start signal can be asynchronous or delayed with respect to a touch frame synchronization signal generated by the display driving circuit.
