    Abstract: Roll-to-roll processes for manufacturing touch sensors using a sheet of patterned photoresist film are disclosed. The photoresist film can include a sheet of photoresist material, such as DFR, that has been patterned by removing portions of the photoresist film using a die or laser cutting technique. In some examples, the photoresist film can be patterned such that the patterned photoresist film can be laminated to a base film and used as an etching mask or a photoresist layer in a roll-to-roll manufacturing process. In this way, the patterned photoresist film can be used in place of conventional photoresist films in roll-to-roll processes, thereby obviating the need for subsequent exposure and development operations that would otherwise be performed when using conventional photoresist films. As a result, the chance that a defect is introduced into the touch sensors is reduced by reducing the number of operations performed in the roll-to-roll process.

    Abstract translation: 公开了使用一张图案化的光致抗蚀剂膜制造触摸传感器的卷对卷工艺。 光致抗蚀剂膜可以包括通过使用模具或激光切割技术去除光致抗蚀剂膜的部分而被图案化的光致抗蚀剂材料片，例如DFR。 在一些实例中，可以对光致抗蚀剂膜进行图案化，使得图案化的光致抗蚀剂膜可以层压到基膜上并且在卷对卷制造工艺中用作蚀刻掩模或光致抗蚀剂层。 以这种方式，图案化的光致抗蚀剂膜可以用于代替常规光致​​抗蚀剂膜的卷对卷工艺，从而避免了在使用常规光致抗蚀剂膜时否则将进行的后续曝光和显影操作的需要。 结果，通过减少在卷对卷过程中执行的操作次数来减少引入到触摸传感器中的缺陷的机会。

    Abstract: Processes for manufacturing touch sensors with one or more guard traces to reduce the effect of moisture damage are provided. One example process can include forming one or more guard traces between an edge of the touch sensor and the metal traces that route the drive and sense lines to bond pads. The one or more guard traces can be uncoupled from the drive lines and sense lines to protect the inner metal traces from moisture damage. In some examples, ends of the one or more guard traces can be coupled to ground by copper. In other examples, ends of the one or more guard traces can be coupled to ground by indium tin oxide or the one or more guard traces can be coupled to ground by a strip of indium tin oxide. In yet other examples, the guard trace can be floating (e.g., not coupled to ground).

    Abstract: Displays with touch sensing circuitry integrated into the display pixel stackup are provided. An integrated touch screen can include multi-function circuit elements that can operate as circuitry of the display system to generate an image on the display, and can also form part of a touch sensing system that senses one or more touches on or near the display. The multi-function circuit elements can be, for example, capacitors in display pixels that can be configured to operate as storage capacitors/electrodes, common electrodes, conductive wires/pathways, etc., of the display circuitry in the display system, and that may also be configured to operate as circuit elements of the touch sensing circuitry.

    Abstract: A touch sensitive device that includes a touch sensor having an opaque passivation layer is disclosed. The opaque passivation layer can be made from an organic or inorganic material, such as acrylic. The opaque passivation layer can be positioned in the touch sensitive device between the cover material of the device and conductive traces located on the touch sensor to hide the conductive traces from the user's view and protect the conductive traces from corrosion. Processes for making the touch sensitive devices that include a touch sensor having an opaque passivation layer are also disclosed.

    Abstract: High aspect ratio touch sensor panels are disclosed in which multiple row electrode blocks can be formed in a single row within an active area of the touch sensor panel, each row electrode block including a plurality of vertically adjacent row electrodes, or in some instances only one row electrode. In addition, each column electrode can be separated into multiple column electrode segments, each column electrode segment being vertically oriented and formed in a different column. The column electrode segments associated with any one column electrode can be spread out so that each of these column electrodes segments can be co-located and associated with a different row electrode block.
