Patent number: 10642417Abstract: 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.Type: GrantFiled: August 3, 2016Date of Patent: May 5, 2020Assignees: BOE TECHNOLOGY GROUP CO., LTD., HEFEI BOE OPTOELECTRONICS TECHNOLOGY CO., LTD.Inventors: Lei Hua, Qing Yang, Hongchao He
