Diamond based touch sensor panel architectures

A method for operating a touch sensor panel including a first set of touch electrodes, a second set of touch electrodes disposed in a first layer of the touch sensor panel, and a plurality of guard electrodes disposed in a second layer of the touch sensor panel different from the first layer, the method comprising:

• operating the first set of touch electrodes as drive electrodes;
• and
• operating the second set of touch electrodes as sense electrodes,
• wherein:
• the first set of touch electrodes are disposed in areas corresponding to gaps in the first layer of the touch sensor panel between the second set of touch electrodes,
• the second set of touch electrodes disposed in the first layer overlap at least partially the plurality of guard electrodes disposed in the second layer, and
• a given row or column of touch electrodes of the second set of touch electrodes includes a plurality of subsets of touch electrodes that are separately addressable by touch sensing circuitry.

An electronic device comprising:

• a display;
• a touch sensor panel including a first layer and a second layer and including a first plurality of electrodes, a second plurality of electrodes and third plurality of electrodes;
• and
• a touch controller configured to perform a touch sensing operation using the touch sensor panel;
• wherein:
• the second plurality of electrodes is disposed in the first layer and is configured to operate as sense electrodes for the touch sensing operation;
• the third plurality of electrodes is disposed in the second layer and is configured to operate as guard electrodes for the touch sensing operation;
• the first plurality of electrodes is disposed in areas corresponding to gaps in the first layer of the touch sensor panel between the second plurality of electrodes,
• the second plurality of electrodes overlap at least partially the plurality of third electrodes disposed in the second layer, and
• the touch controller is configured to sense, for a given column of the touch sensor panel, a first capacitance for a first sense electrode including a first interconnected plurality of the second plurality of electrodes and a second capacitance for a second sense electrode including a second interconnected plurality of the second plurality of electrodes different from the first interconnected plurality.
