Abstract: A touch device and an operating method thereof are provided. The operating method includes the following steps. A plurality of data baseline values of the touch panel is calibrated and set during an initialization of a touch panel. A plurality of touch data is obtained after scanning the touch panel. A plurality of touch values corresponding to the touch panel is calculated according to the data baseline values and the touch data. A touch point is detected according to the touch values. When the touch data is complied with a re-calibration requirement, the data baseline values are re-calibrated and reset.

Abstract: A touch device and a method for detecting touch on the touch device are provided. The method includes the following steps. A plurality of touch values corresponding to a plurality touch region of a touch panel are obtained. A touch block is determined according the touch values and a touch threshold value, which the touch regions within the touch block are adjacent to one another. The touch values of the adjacent touch regions within the touch block are compared with one another to determine whether there is a touch value trough point in the touch block. It is determined that whether the touch block corresponds to a single touch or a multi-touch according to whether there is the touch value trough point in the touch block.
