Abstract
A scan method for a touch panel has steps of: receiving a self-sensing frame; calculating sensing slopes between each sensing line and its neighboring sensing lines in the self-sensing frame; determining whether any sensing slope is larger than a slope threshold, and marking the sensing line if the sensing slope is larger than the slope threshold; and executing a mutual scan approach on the marked sensing lines to produce a mutual sensing frame without sensing point caused by noise. Further, the present invention also increases the frame rate since only a part of sensing lines need to be scanned.
