Abstract: A projected capacitive touch sensor includes a sensor grid. The sensor grid includes one or more electrically conductive rows arranged in an at least partially transparent row layer. The sensor grid includes one or more electrically conductive columns arranged in an at least partially transparent column layer that is spaced apart from the row layer. The projected capacitive touch sensor includes a border region that surrounds at least a portion of the sensor grid. The border region includes a wired bus region that includes a row bus that extends from the one or more electrically conductive rows and a column bus that extends from the one or more electrically conductive columns. The projected capacitive touch sensor includes one or more connectors that are electrically connected to the row bus and the column bus. The wired bus region is configured to fold over an edge of a borderless display.

Abstract: A capacitive touch sensor is described. The touch sensor includes a sensor grid that includes a trace that has a trace start point and end point, is electrically conductive between the trace start point and the trace end point, is formed in one or more pairs of trace cells that each include a first trace cell and a second trace cell that is rotationally symmetrical to the first trace cell. The trace start point and the trace end point define a trace axis. A trace direction is defined from the trace start point to the trace end point. A trace-perpendicular direction is defined as being perpendicular to the trace direction. A segment of the trace that is formed in the first trace cell includes a first portion, a second portion, a third portion, a fourth portion, a fifth portion, a sixth portion, a seventh portion, and an eighth portion.
