Abstract:
A borderless touchscreen panel includes a first conductive layer having rows of capacitive sensors and receiving traces, and a second conductive layer having columns of sensor bars and transmitting traces. The capacitive sensors are coupled to control circuitry via the receiving traces, and the sensor bars are coupled to the control circuitry via the transmitting traces. Peripheral sensor bars are disposed over the receiving traces such that the receiving traces can be routed within an active portion of the borderless touchscreen panel without obstructing its touch-detection capabilities. Furthermore, the receiving traces are comprised of a transparent material such as indium tin oxide, and therefore do not obstruct the display capabilities of the active portion. Thus, there is no need for an inactive border region since the receiving traces are disposed within the active portion without obstructing either the touch-detection or display capabilities of the borderless touchscreen panel.
