摘要： The present disclosure provides a method and apparatus for determining touching action and a display device. The method comprises the following steps of: determining a first touching region where a variation value of capacitance is larger than or equal to a first preset value during each period of N consecutive periods, in which N≧2; and outputting a touching signal according to the first touching region, wherein each period of the N consecutive periods is a scanning period of the touch pane. The embodiment of the present disclosure may scan all of the touching regions of the touch panel during N consecutive scanning periods, and then determine the first touching region has a variation value of capacitance larger than or equal to the first preset value during the N consecutive scanning periods to be a region touched by the user so as to output a touch signal based on the region. Since it can't determine a touching region has a variation value of capacitance larger than or equal to a preset value only during a few scanning periods, the accuracy for determining the touching event may be enhanced so as to avoid false trigger of the touching event of a touch panel by external noises.
