Abstract:
In touch panel display device, a first touch electrode group has a first plurality of touch electrodes and a second touch electrode group has a second plurality of touch electrodes. A first current supplier circuit supplies a first current during a first current supply period to the first touch electrode group, and the second current supplier circuit supplies a second current during a second current supply period to the second touch electrode group. The sensing signal receiver circuit holds a first touch voltage for the first touch electrode group following the first current supply period, and holds the second touch voltage for the second touch electrode group following the second current supply period. The sensing signal receiver determines based on the first held touch voltage and the second held touch voltage, whether a touch occurred in each of the first touch electrode group and the second touch electrode group.
