Abstract
Touch sensor panels (104) have 2-D periodic arrangements of electrodes (304) connected together forming a plurality of horizontal and vertical logical lines (506, 514) for measuring X-Y coordinates of a user's touch. Electrodes forming the horizontal logical lines are interleaved with electrodes forming the vertical logical lines. Each of the vertical and horizontal logical lines includes multiple tracks (502, 504, 510, 512). The tracks of each logical line are cross connected by in-plane cross connects (314, 318) formed in the same layer by the same process that is used to form the electrodes. Diamond and square electrode embodiments are described.
Claims19
A touch sensor panel for sensing coordinates of a user's touch, the touch sensor panel comprising:
- a first plurality of logical lines for sensing a first coordinate, wherein each of the first plurality of logical lines includes:
- a first plurality of parallel adjacent tracks extending in a first direction, each track including electrodes connected in series, and
- a first plurality of in-plane cross connects connecting the first plurality of parallel adjacent tracks to provide redundant signal paths for each of the first plurality of logical lines,
- a first plurality of parallel adjacent tracks extending in a first direction, each track including electrodes connected in series, and
- wherein the first plurality of parallel adjacent tracks and the first plurality of in- plane cross connects are disposed in a common plane;
- a second plurality of logical lines for sensing a second coordinate, wherein each of the second plurality of logical lines includes:
- a second plurality of parallel adjacent tracks extending in a second direction perpendicular to the first direction, each track including electrodes connected in series, and
- a second plurality of in-plane cross connects connecting the second plurality of parallel adjacent tracks to provide redundant signal paths for each of the second plurality of logical lines
- wherein the second plurality of in-plane cross connects are disposed in the common plane.
