Split sense lines for negative pixel conpensation
Abstract:
A touch panel configured to compensate for negative pixel effect is disclosed. The panel can be configured to increase a capacitive sense signal, indicative of a touching or hovering object, in order to compensate for an increase in negative capacitance when the object is poorly grounded. To perform the compensation, the panel can be configured to have split sense lines so as to increase the number of electric fringe fields forming the sense signal, thereby providing a sense signal that is substantially stronger than the negative capacitance signal. Each sense line can be split into two or more strips.
