Abstract:
Disclosed are a capacitive touch control device and a method thereof. A top face of a substrate is provided with first and second electrode groups, which each include a plurality of strip-like electrodes spaced from each other by a preset distance. The electrodes of the first and second electrode groups are respectively connected by first and second group scanning lines to a scanning circuit. When the first group scanning lines drive the electrodes of the first electrode group, the second group scanning lines carry out scanning operation on the electrodes of the second electrode group, and when the second group scanning lines drive the electrodes of the second electrode group, the first group scanning lines carry out scanning operation on the electrodes of the first electrode group. And, a touch location can thus be determined by using a microprocessor.
