Abstract:
1. A touch panel, wherein the touch panel has a first region, a second region, a third region and a fourth region, the first region and the second region being arranged along a first direction, the third region and the fourth region being arranged along the first direction, the first region and the third region being arranged along a second direction, the second region and the fourth region being arranged along the second region, the first direction being substantially perpendicular to the second direction, and the first through fourth regions comprising: a plurality of driving lines, comprising a first group of driving lines configured in the first region, a second group of driving lines configured in the second region, a third group of driving lines configured in the third region, and a fourth group of driving lines configured in the fourth region; a plurality of sensing lines arranged intersecting with the driving lines, comprising a first group of sensing lines configured in the first region, a second group of sensing lines configured in the second region, a third group of sensing lines configured in the third region and the first region, and a fourth group of sensing lines configured in the fourth region and the second region; and a plurality of sensing units arranged in an array, and each of the sensing units being electrically coupled to a corresponding one of the driving lines and a corresponding one of the sensing lines; wherein the sensing units of the first region in a same row along the first direction are electrically coupled to one of the first group of driving lines, the sensing units of the second region in a same row along the first direction are electrically coupled to one of the second group of driving lines, the sensing units of the third region in a same row along the first direction are electrically coupled to one of the third group of driving lines, and the sensing units of the fourth region in a same row along the first direction are electrically coupled to one of the fourth group of driving lines; wherein the sensing units of the first region in a same column along the second direction are electrically coupled to one of the first group of sensing lines, the sensing units of the second region in a same column along the second direction are electrically coupled to one of the second group of sensing lines, the sensing units of the third region in a same column along the second direction are electrically coupled to one of the third group of sensing lines, and the sensing units of the fourth region in a same column along the second direction are electrically coupled to one of the fourth group of sensing lines; wherein the first through fourth groups of sensing lines pass through a single side of the touch panel, the first and second groups of the driving lines respectively pass through two opposite sides of the touch panel, and the third and fourth groups of the driving lines respectively pass through the two opposite sides of the touch panel; wherein the third group of sensing lines passes through the first region without being electrically coupled to the sensing units of the first region, and the fourth group of sensing lines passes through the second region without being electrically coupled to the sensing units of the second region.
