Abstract
An electronic device having a touch sensitive panel has an opened and a closed state, and comprises a sensor circuit, a touch simulation facility and a comparator. The sensor circuit is for generating a touch signal indicative for a position where a touch of the touch sensitive panel is detected. The touch simulation facility is for evoking a touch signal at a position of the touch sensitive panel, and comprises a touch simulation element which in the closed state of the electronic device is arranged opposite the touch sensitive panel. The comparator is for comparing the touch signal with a reference value corresponding to the touch simulation element and for generating a correction signal for adjusting a setting of the sensor circuit for compensation of a difference detected between the position where the touch signal is evoked and the position indicated by the touch signal.
