TOUCH APPARATUS AND TOUCH SENSING METHOD THEREOF

摘要

A touch sensing method of a touch panel may include: defining at least one of at least one sensing loop as at least one reference sensing loop, wherein the sensing loop is disposed in the touch panel for sensing a touch event; providing a driving signal to the reference sensing loop in order to read at least one reference signal from the reference loop during an electrical detection period; providing the driving signal to the sensing loop in order to read at least one sensing signal from the sensing loop during a touch sensing period; and detecting a touch position of the touch event according to the reference signal and the sensing signal. Several touch apparatuses are also provided.
