Abstract: A method for calibrating a functional icon display position of a control device is provided. The control device includes a transparent key and a display panel. The method includes the following steps. Firstly, an image capturing device is used to photograph a functional icon, and thus a real spatial relationship of the functional icon in a visible region of the transparent key is obtained. Then, a position offset amount is obtained according to a result of comparing the real spatial relationship with a reference spatial relationship. If the position offset amount is larger than the enable calibration threshold value, a calibrated icon display start coordinate position is obtained according to the position offset amount. The present invention also provides a control device using the calibrating method.
