Field-line repeater (FLR) structure of a sense array

摘要

Apparatuses and methods of field-line repeater structures for sense arrays are described. One apparatus includes a substrate, a capacitive-sense array with electrodes disposed on one or more sides of the substrate in one or more layers and a protective cover layer disposed to cover the capacitive-sense array. A coating film is disposed over the protective cover layer and a field-line repeater (FLR) structure of floating electrodes is disposed between the coating film and the protective cover layer.

主权项

1. A touch-sensing device comprising:
a capacitive-sense array comprising a plurality of electrodes disposed in a first layer; a second layer of material to cover the capacitive-sense array; a third layer of material disposed over the second layer; and a field-line repeater structure comprising a plurality of floating electrodes disposed between the second layer and the third layer, wherein the plurality of electrodes are diamond-shape electrodes and arranged in a plurality of rows and a plurality of columns, wherein the plurality of floating electrodes comprises a first set of floating electrodes arranged in a diamond shape and disposed to overlap portions of at least two of the diamond-shape electrodes in a first row of the plurality of rows and to overlap portions of at least two of the diamond-shape electrodes in a first column of the plurality of columns.
