Abstract: This relates to a force-sensitive touch screen including a metallization layer for force sensing. In some examples, the force-sensing metallization layer can be deposited between a color filter layer and a thin film transistor (TFT) layer (including an array of TFTs) of the touch screen. In some examples, the metallization layer can be electrically coupled to a patterned conductive layer. Together, a force-sensing metallization trace of the metallization layer and a patterned conductor of the patterned conductive layer can act as a force sensor. Additionally or alternatively, the device can include a force-sensing metallization layer and a conductive layer (patterned or not) located beneath the TFT layer (i.e., rather than between a color filter layer and the TFT layer).

Abstract: Flexible circuits for routing signals of a device, such as a touch sensor panel of a touch sensitive device, are provided. The flexible circuit can include a first set of traces for routing a first set of lines and a second set of traces for routing a second set of lines. The first set of traces can couple together the ends of at least a portion of the first set of lines. Additionally, the first set of traces can be non-intersecting or non-overlapping with the second set of traces. The flexible circuit can have a T-shape configuration and can be incorporated within a touch sensitive device, display device, printed circuit board, or the like. The flexible circuit can be placed over another flexible circuit, and can extend onto the device.
