Abstract
A detecting method for a touch panel includes providing a sensing matrix having a plurality of sensing units; detecting sensing data generated from the sensing unit and defining the sensing unit as a touch point or a non-touch point based on the sensing data; and grouping at least a portion of the touch points to form a touch point group, wherein projection of a touch point overlaps a projection of at least one touch point of the touch point group in one of a row direction and a column direction while adjacent to a projection in the other direction of at least one touch point of the touch point group; retrieving extreme positions of the touch point group in the row direction and the column direction; and determining a touch center position based on the extreme positions in the row direction and the column direction.
