<p>A touch panel (110) and a touch position detection method thereof and a touch display device (100). The touch panel (110) comprises multiple first sensing pads (112) arranged along a first direction, multiple second sensing pads (113) arranged along a second direction, and multiple third sensing pads (114) arranged along a third direction. The method comprises the following steps: detecting changes in the capacitance values of the first sensing pads (112) in the first direction; detecting changes in the capacitance values of the second sensing pads (113) in the second direction; detecting changes in the capacitance values of the third sensing pads (114) in the third direction; and determining at least one touch position according to the changes in the capacitance values of the first sensing pads (112), the second sensing pads (113), and the third sensing pads (114). The present invention can alleviate the problem of wrong sensing points of multiple touching.</p> |
