Abstract: Touch sensor configurations for reducing electrostatic discharge events in the border area of a touch sensor panel is disclosed. Touch sensors (e.g., electrodes formed on the cover material and/or the opaque mask) can be susceptible to certain events such as arcing and discharge/joule heating, which may negatively affect touch sensor performance. Examples of the disclosure can include increasing the trace width, spacing, and/or thickness in the border area relative to the trace width, spacing, and/or thickness in the visible/active area along one or more sides of the touch sensor panel. In some examples, touch electrodes can be located exclusively in the visible/active areas along one or more sides of the touch sensor panel, while dummy sections can be included in both the border and visible/active areas. Additionally or alternatively, one or more gaps between adjacent touch electrodes in the border area or serpentine routing can be included.

Abstract: Touch sensor panel configurations for reducing wobble error for a stylus translating on a surface over and between electrodes of the touch sensor panel are disclosed. In some examples, electrodes with more linear signal profiles are correlated with lower wobble error. In some examples, diffusing elements formed of floating segments of conductive materials can diffuse signal from a stylus to a plurality of electrodes, thus, making the signal profiles associated with the electrodes more linear. In addition, diffusing elements can be configured to improve the optical uniformity of the touch sensor panel. In some examples, the diffusing elements can be formed on the same layer as floating dummy pixels and resemble a plurality of merged floating dummy pixels.

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: 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.

Abstract: A touch sensor panel including artwork formed on the touch sensor panel is disclosed. The touch sensor panel stackup can include a substrate, one or more underlying layers, one or more patterned transparent conductive layers, a passivation layer, artwork, and an adhesive layer. The artwork on the touch sensor panel can be formed by aligning to the touch sensor pattern or alignment marks. In some examples, the artwork can be formed on a discrete touch sensor panel, and the discrete touch sensor panel can be bonded to a cover glass or cover material. In some examples, the touch sensor panel can be a Dual-sided Indium Tin Oxide (DITO) stackup. In some examples, the drive lines and the sense lines of the touch sensor panel can be formed on separate substrates, and the substrates can be bonded together using an adhesive.
