Electronic device and touch screen thereof

The utility model relates to an electronic device and a touch screen thereof. The touch screen comprises an electromagnetic induction type touch-detecting module for detecting the location which users touch with an electromagnetic stylus, a resistant type touch-detecting module or a capacity type detecting module for detecting the location which users touch with hands and a screen control module. The resistant type touch-detecting module or the capacity type detecting module is arranged above the electromagnetic induction type touch-detecting module. The screen control module is respectively connected with the electromagnetic induction type touch-detecting module and the resistant type touch-detecting module or the capacity type detecting module, is used for changing detected locations into touch point coordinates, and preferably changes the locations detected by the electromagnetic induction type touch-detecting module into the touch spot coordinates when the screen control module receives signals detected by the electromagnetic induction type touch-detecting module and the resistant type touch-detecting module or the capacity type detecting module at the same time. The electronic device and the touch screen thereof can support finger touch and electromagnetic stylus touch simultaneously, and can prevent users from operating by mistake.
