Abstract:
A multi-touch capacitive touch sensor panel can be created using a substrate with column and row traces formed on separate layers of the substrate. The column and row traces can include sections extending from a central trace and forming a rectilinear trace pattern with sections of the columns and rows interdigitated with one another. The trace pattern can comprise a plurality of pixels arranged continuously across the sensor panel. In this manner, the sensor panel can provide a linear or near linear response to touches across the touch sensor panel.
