Abstract
A method for determining scanning times of touch driving pulse in a touch panel includes steps of: judging a current gate line scan period is in which one of a data updating time period and a blanking time period; if the current gate line scan period is in the data updating time period, setting a scanning times of touch driving pulse in the current gate line scan period to be a first value; and if the current gate line scan period is in the blanking time period, setting the scanning times of touch driving pulse in the current gate line scan period to be a second value. The first value is different from the second value, and a time for touch driving pulse scanning is non-overlapped with another time for providing display data to data lines of the touch panel in each scan line scan period.
