The invention discloses a method for obtaining calibration parameters of a touch screen comprising displaying at least two preset calibration reference points on a LCD; obtaining physical coordinates of sampling points obtained by clicking on positions corresponding to the calibration reference points on the touch screen and displaying the sampling points according to the physical coordinates and the calibration parameters; and if it is determined that the displayed sampling points are not coincident with their corresponding calibration reference points, adjusting distances between the sampling points and their corresponding calibration reference points, determining a minimal deviation between the adjusted sampling points and their corresponding calibration reference points and applying the minimal deviation to update the calibration parameters. The invention also provides an apparatus for obtaining calibration parameters of a touch screen. The invention improves use experience of users when performing calibration and assists the users in obtaining more accurate calibration parameters. |
