Abstract
A touch control device is provided. A protective cover protects the touch control device and includes a top-surface to sustain a touch action performed by the user. A flat touch sensing layer includes many first direction-detection electrodes second direction-detection electrodes. The fast and second direction-detection electrodes are isolated by a transparent insulating material at the position where the first direction-detection electrodes cross the second direction-detection electrodes. The first and second direction-detection electrodes constitute a flat sensing pattern. A pressure-sensing layer is disposed between the protective cover and the flat touch sensing layer and includes at least one pressure-sensing unit constituting a first pattern. The overlap ratio between the projection of the first pattern onto the flat touch sensing layer and the flat sensing pattern is less than or equal to about 5% of the flat sensing pattern.
