TOUCH SENSOR DEVICE

摘要

The present invention discloses a touch sensor device. The touch sensor device comprises: a panel that includes plural touch keys indicating the touch points of a contact object; plural first touch pads attached to the points corresponding to the plural touch keys of the panel to convert the touch information of the object into a first electric signal; plural second touch pads attached between the first touch pads to convert the touch information of the conductive substance stuck to the object into a second electric signal; and a sensing unit that receives the first electric signal to output plural sensing signals for activating the operations set up at the contacted touch keys, and uses the first and second electric signals to discriminate normal or abnormal touch input of the contact object. According to the present invention, the touch sensor device can discriminate the abnormal touch input of the contact object to prevent malfunctions which are not initially intended. In addition, the touch sensor device can reduce unnecessary power consumption by reducing the operations for the abnormal touch input. Therefore, the operational reliability of the contact sensor device can be improved.
