Abstract: A sensor array package can include a sensor disposed on a first side of a substrate. Signal trenches can be formed along the edges of the substrate and a conductive layer can be deposited in the signal trench and can couple to sensor signal pads. Bond wires can be attached to the conductive layers and can be arranged to be below a surface plane of the sensor. The sensor array package can be embedded in a printed circuit board enabling the bond wires to terminate at other conductors within the printed circuit board.

Abstract: A touch screen including display pixels with capacitive elements is provided. The touch screen includes first common voltage lines connecting capacitive elements in adjacent display pixels, and a second common voltage line connecting first common voltage lines. Groups of pixels can be formed as electrically separated regions by including breaks in the common voltage lines. The regions can include a drive region that is stimulated by stimulation signals, a sense region that receives sense signals corresponding to the stimulation signals. A grounded region can also be included, for example, between a sense region and a drive region. A shield layer can be formed of a substantially high resistance material and disposed to shield a sense region. A black mask line and conductive line under the black mask line can be included, for example, to provide low-resistance paths between a region of pixels and touch circuitry outside the touch screen borders.

Abstract: The formation of metal traces in the border areas of a touch sensor panel to provide improved reliability, better noise rejection, and lower manufacturing costs is disclosed. The metal traces can be coupled to rows on the touch sensor panel in an interleaved manner, so that any two successive rows can be coupled to metal traces in border areas on opposite sides of the touch sensor panel. In addition, by utilizing the full width available in the border areas in some embodiments, the metal traces can be formed from higher resistivity metal, which can reduce manufacturing costs and improve trace reliability. The wider traces can also provide better noise immunity from noise sources such as an LCD by providing a larger fixed-potential surface area and by more effectively coupling the drive lines to the fixed potential.
