Abstract:
1. A touch device comprising: a touch panel having a plurality of column electrodes and a plurality of row electrodes, and the column electrodes are interlaced with the row electrodes to form a plurality of touch areas; and a touch detecting unit coupling to the touch panel, detecting a plurality of touch data of the touch panel to calibrate and set a plurality of data baseline values of the touch panel during an initialization, obtaining the touch data of the touch panel after scanning the touch panel, calculating a plurality of touch values according to the data baseline values and the touch data for detecting a touch point according to the touch values, and the data baseline values of the touch panel are re-calibrated and reset by the touch detecting unit after the touch data are complied with a re-calibration requirement, wherein the touch data is not utilized for detecting the touch point during the initialization while scanning is taking place during the initialization.
