[0026] figure 2 A schematic plan view of the projected capacitive touch panel involved in the embodiment of the present application is schematically shown. The panel includes the projected capacitive touch panel including M sensing lines L arranged along one direction (for example, along the x-axis direction) 1 , L 2 ,... L M , where L 1 and L M is the edge sense line. P21, P22 and P23 respectively represent three touch points, the center of the cross line of each point represents the actual position of each point, and the area framed by the thick line represents the touch sensing range.
