An apparatus and method for changing a touch mode in a device having a touch screen including a plurality of touch sensors is provided. In a method for changing a touch mode in the device, the device determines a variation in the influx of electric charges during a time period in a charging process, and determines whether the variation exceeds a given critical value. If the variation exceeds the critical value, the device operates the touch screen in a self capacitive touch mode using the touch sensors as sending ends for sending the electric charges in order to detect a touch event. Therefore, the device of a mutual capacitive touch type can detect a touch event by using the self capacitive touch mode even in unstable power environments. |
