Abstract
A touch detection device for touchscreen includes a frame and at least one printed circuit board mounted on one face of the frame. The printed circuit boards have a plurality of transmitters, a plurality of receivers, and a wireless signal transmission unit mounted thereon. By using the transmitters and the receivers to detect touched positions on a touchscreen, and using the wireless signal transmission unit to transmit a touch signal, the touch detection device can be conveniently installed on the touchscreen with simplified cable wiring and avoid the risk of being undesirably pulled by an external force to adversely affect the signal transmission thereof.
