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.
