Electronic device with a touch sensitive panel, method for operating the electronic device, and display system

摘要

The present invention relates to an electronic device (1) having a touch sensitive panel (10). The electronic device is arrangeable during use into one of at least an opened and a closed state, and comprises:
- a sensor circuit (20) for generating a touch signal (Sxy) indicative for a position where a touch of the touch sensitive panel was detected,
- a touch simulation facility (30) for evoking a touch signal at at least one position (x0,y0) of said touch sensitive panel, and which touch simulation facility comprises at least one touch simulation element (34) which in a closed state of the electronic device is arranged opposite said touch sensitive panel,
- a comparator (40) for comparing a touch signal (Sxy) of the sensor circuit with a reference value (SRxy) corresponding to the at least one touch simulation element and for generating a correction signal (Scal) for adjusting a setting of the sensor circuit (20) for compensation of a difference detected between the position of said touch sensitive panel where the touch signal was evoked and the position indicated by the touch signal (Sxy).
