1. touch panel device comprises:

  • Touch pad is used for the identification contact position, and this touch pad comprises the upper film with first conductive layer and the lower film with second conductive layer;

    A plurality of somes septs, it is used for film and lower film on described contact position separation is described;

    WithThe touch pad controller is used for calculating the coordinate figure corresponding with the contact position on the touch pad,Wherein, according to the control to the spacing of the height of each described a plurality of somes sept and some sept, the triggering power of described touch pad is set to the value between 80g~

    150g, and described touch pad controller compensates the coordinate figure mistake that the dual touch because of touch pad causesWherein the touch pad controller calculates the first the first coordinate figure that touches that produces in touch pad, and when receiving the input signal corresponding with the second touch in the predetermined time cycle, the touch pad controller calculates with second and touches the second corresponding coordinate figure, and by this second coordinate figure and preset reference coordinate figure are compared to determine whether this second coordinate figure exists the mistake that causes because of dual touchWherein when the second coordinate figure surpassed the preset reference coordinate figure, the touch pad controller determined that this second coordinate figure is wrong.
