Abstract
Touch sensitive input devices and routing trace configurations designed to reduce border dimensions of such devices are provided herein. The touch sensitive input devices include a touch panel having a plurality of transmit lines and a plurality of receive lines, which are arranged with the plurality of transmit lines in a grid pattern, such that a sense node is disposed on the touch panel at each intersection of the transmit and receive lines. More specifically, the touch panel includes a first subset of the transmit lines coupled to routing traces on only a first side of the touch panel, a second subset of the transmit lines coupled to routing traces on only a second side of the touch panel, and a third subset of the transmit lines coupled to routing traces on both the first side and the second side of the touch panel. Methods are provided herein for compensating for differences in routing trace path lengths, so as to provide accurate detection of touch event locations on the touch panel.
