A driving method of an LCD panel having a plurality of display groups comprising a plurality of display cells and respectively coupled to a data electrode and a gate electrode. The program varies parameters of a point of communication, such as the location, transmission power, channel frequency, antenna height, and the like, alone or in combination, to measure, test, andor evaluate which parameter changes increase the market coverage of a target market or area. By performing the calibration method the scale factor of the angular measurement device and the strength and direction of gravity can be obtained andor corrected.
