Abstract:
1. An electronic device having a first and a second part coupled to each other, said electronic device being arrangeable during use into one of at least an opened and a closed state by the first and the second parts, said electronic device comprising: a touch sensitive panel connected to the first and the second part; a sensor circuit for generating a touch signal indicative for a sensed position where a touch of the touch sensitive panel is detected; a touch simulation apparatus comprising at least one touch simulation element disposed on a rear surface of the touch sensitive panel, arranged such that when the electronic device is in the closed state, the touch simulation element is located opposite to the front surface of said touch sensitive panel and mechanically contacts said touch sensitive panel at at least one reference position of said touch sensitive panel to evoke a calibration touch signal; and a comparator for comparing the calibration touch signal with a reference value corresponding to the reference position of the at least one touch simulation element and for generating a correction signal (Scal) for adjusting a setting of the sensor circuit for compensation of a difference detected between the reference position of said touch sensitive panel where the touch signal is evoked and the sensed position indicated by the calibration touch signal, wherein in the closed state of the electronic device, the touch sensitive panel is stored in a rolled state in the first part.
