Abstract
In one embodiment, a touch sensor includes multiple first electrodes along a first direction. Each of the first electrodes includes multiple first conductive regions. The touch sensor also includes multiple second electrodes along a second direction that is substantially perpendicular to the first direction. Each of the second electrodes includes one second conductive region. The one second conductive region of each of the second electrodes are interdigitated with one of the first conductive regions of each of the first electrodes. The first and second conductive regions are disposed on a layer on or within a display stack including one or more layers.
Claims20
A touch sensor comprising:
- a plurality of first electrodes along a first direction, each of the first electrodes comprising a plurality of first conductive regions;
- and
- a plurality of second electrodes along a second direction that is substantially perpendicular to the first direction, each of the second electrodes comprising one second conductive region, the one second conductive region of each of the second electrodes being interdigitated with one of the first conductive regions of each of the first electrodes in a manner such that the second electrode does not intersect in a touch sensitive area the plurality of first electrodes, the first and second conductive regions being disposed on a layer on or within a display stack comprising one or more layers.
A device comprising:
- a display stack comprising a plurality of layers, the plurality of layers comprising a cover layer and one or more other layers;
- a touch sensor comprising:
- a plurality of first electrodes along a first direction, each of the first electrodes comprising a plurality of first conductive regions;
- and
- a plurality of second electrodes along a second direction that is substantially perpendicular to the first direction, each of the second electrodes comprising one second conductive region, the one second conductive region of each of the second electrodes being interdigitated with one of the first conductive regions of each of the first electrodes, the first and second conductive regions being disposed on a substrate, the substrate being a particular one of the plurality of layers, other than the cover layer, within the display stack;
- and
- one or more computer-readable non-transitory storage media embodying logic that is configured when executed to control the touch sensor.
