Abstract
The general field of the invention is that of touchscreen devices with projected capacitive detection comprising a touch-sensitive matrix panel comprising a plurality of conductive rows and conductive columns, said panel being connected to electronic control means. The electronic control means generate two periodic transmission voltages transmitted at two different frequencies. Analysis of the reception voltages is used to determine the positions of presses on the touch-sensitive panel, including when a row or column is cut. Pressing on a cut row or column is basically determined by calculating the barycenters of 'virtual' hollows in the reception voltages corresponding to this cut row or column.
