Abstract
A touch scanning method shortening a first touch latency includes: scanning a Mth column of the N-column touch panel according to a touch scan (TSHD) signal; determining whether the finger is on the Mth column of the N-column touch panel according to a scan data signal; performing a fast done process according to a fast done signal when the finger is on the Mth column of the N-column touch panel; determining whether M equals to N when the finger is not on the Mth column of the N-column touch panel; and resetting M to 1 according to a scan start signal and performing an algorithm according to a finish flag signal.
