摘要： 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.

摘要： 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.

摘要： An apparatus is disclosed. In some examples, the apparatus comprises a cover substrate having a front surface, a first edge and a first cavity adjacent to the first edge. In some examples, the apparatus comprises a plurality of touch sensor electrodes disposed opposite the front surface of the cover substrate. In some examples, the apparatus comprises at least one touch sensor edge electrode disposed within the first cavity on a surface that is angled relative to the front surface of the cover substrate. In some examples, at least one touch sensor edge electrode is disposed on an outward facing curved surface of the first cavity. In some examples, the plurality of touch sensor electrodes are formed from a first conductive material and the at least one touch sensor edge electrode is formed from a second conductive material. In some examples, the first conductive material is transparent, and the second conductive material is non-transparent. In some examples, the second conductive material is formed on a black mask layer disposed around a perimeter of a bottom surface of the cover substrate.
