Abstract
A driver integrated circuit (IC) includes: a built-in capacitor, a reading circuit, an analog-to-digital converter (ADC) and a coupling circuit, wherein the reading circuit receives a sensing signal from a touch panel and outputs an analog sensing data; the ADC is coupled to the reading circuit, and is used to receive and convert the analog sensing data to a digital sensing data; and the coupling circuit is coupled to the reading circuit, and is used to selectively couple the built-in capacitor to the touch panel when the driver IC operates in a touch sensing mode.
