    Abstract: This invention discloses a touch device for distinguishing true touch. The touch device includes a touch screen, a driving unit, and a sensing unit. The touch screen has a plurality of first conductive lines and second conductive lines where the first and second conductive lines are electrically isolated from each other and stacked to form a plurality of coupling intersections. The driving unit operatively drives the first conductive lines. The sensing unit determines the first conductive lines touched or approached by a plurality of objects and also determines the coupling intersections touched or approached by the objects when the first conductive lines touched or approached by the objects are driven. By doing so, the true touch and the false touch caused by the objects can be determined and distinguished.

    Abstract: The invention discloses a full screen driven detection. A driving signal is simultaneously provided to all first conductive strips arranged in parallel in a first direction in a touch screen, and mutual capacitive signals are detected from all second conductive strips arranged in parallel in a second direction. The mutual capacitive signals can be used for determining whether an external conductive object coupled to the ground is touching or approaching the touch screen or not even if water or other conductive object not coupled to ground is on the touch screen. Thus, the baseline of the mutual capacitive signals can be updated if the touch screen is not touched or approached by any external conductive object coupled to ground over a predetermined period of time.
