Abstract:
1. A capacitive touch control device comprising: a substrate having a capacitive touch control operation surface; a first electrode group comprising a plurality of strip-like electrodes arranged on the capacitive touch control operation surface of the substrate and respectively connected to first group scanning lines connected to a scanning circuit, the electrodes being spaced from each other by a preset distance, which defines an interval area; a second electrode group comprising a plurality of strip-like electrodes respectively arranged in the interval areas between the electrodes of the first electrode group and respectively connected to second group scanning lines connected to a scanning circuit; wherein, in a first time interval, when the first group scanning lines impose a driving voltage to the electrodes of the first electrode group and also within the first time interval the second group scanning lines carry out scanning operation by detecting voltage on the electrodes of the second electrode group, and in a second time interval, wherein when the second group scanning lines impose a driving voltage to the electrodes of the second electrode group and also within the second time interval the first group scanning lines carry out scanning operation by detecting voltage on the electrodes of the first electrode group; wherein the electrodes of the second electrode group are parallel to the electrodes of the first electrode group.
