Abstract: 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.
