Publication number: 20120013573Abstract: A pressure detectable touch device includes a first substrate, a conductive layer formed on the first substrate, a second substrate, a first electrode pattern, a second electrode pattern, and a microprocessor. When a user touches a touch operation surface of the touch device in such an extent that the conductive layer and the first electrode pattern are not put into physical contact with each other, the touch device is set in a capacitive touch position detection mode. When the user forcibly depresses the touch operation surface of the touch device or carries out a hand writing input operation on the touch operation surface of the touch device, the conductive layer is caused to physically engage the first electrode pattern, setting the touch device in a resistive touch position detection mode.Type: ApplicationFiled: July 1, 2009Publication date: January 19, 2012Applicant: TPK TOUCH SOLUTIONS INC.Inventors: Chen-yu Liu, Ching-yi Wang
