  • Patent number: 11221719
    Abstract: A sensor pattern and a capacitive touch screen are provided. The sensor pattern comprises: a plurality of unit blocks, and a first unit block of the unit blocks comprises: a first 1st-type sensor element, a first 2nd-type sensor element, and a second 2nd-type sensor element. The first 1st-type sensor element is disposed on a first patterned layer, having a border trace, two parallel main traces, a bridge, a first cell, and a second cell, wherein the first and second cells are not aligned. The first 2nd-type sensor element is disposed on a second patterned layer, having a main trace and a sub-trace, wherein the main trace surrounds the first cell of the first 1st-type sensor element. The second 2nd-type sensor element is disposed on the second patterned layer, having a main trace and a sub-trace, wherein the main trace surrounds the second cell of the first 1st-type sensor element.

  • Patent number: 10712886
    Abstract: A sensing unit in the touch panel includes a first electrode formed in a first film and a second electrode formed in a second film. The first electrode includes multiple extending portions and at least one connecting portion. The extending portions extend along a first direction. The connecting portion extends along a second direction which is different from the first direction. The extending portions are spaced from each other by a distance along the second direction, and the connecting portion connects the extending portions. The second electrode includes a circular pad having an opening. The extending portions at least partially overlap with the circular pad, and the connecting portion is formed in an area overlapping with the opening.
