Abstract: A touch panel module including a touch panel area and a non-touch panel area is provided. The touch panel module includes a touch panel. The touch panel is located in the touch panel area. The touch panel senses a touch gesture by using a plurality of first and second sensing electrodes. At least one part of the first sensing electrodes is located in the non-touch panel area. Another one part of the first sensing electrodes and a whole of the second sensing electrodes are located in the touch panel area. The touch gesture touches the touch panel module to generate a touch area. A touch position corresponding to the touch gesture on the touch panel is determined based on a ratio of an area of the first sensing electrodes touched by the touch gesture and the touch area.
