Abstract
A force sensor includes first and second substrates. The second substrate faces the first substrate. A driving electrode is disposed on a first surface of the first substrate facing the second substrate. A sensing electrode is disposed on the first surface of the first substrate and is spaced apart from the driving electrode. A force sensitive layer is disposed on a first surface of the second substrate, facing the first substrate. The driving electrode includes a main driving protrusion that protrudes from a side surface of the driving electrode, facing the sensing electrode.
Claims21
A sensor, comprising:
- a first substrate;
- a plurality of sensing cells disposed on a first surface of the first substrate;
- a plurality of driving electrodes and a plurality of sensing electrodes respectively facing each other in each of the plurality of sensing cells;
- and
- a plurality of sensing lines respectively connecting the plurality of sensing electrodes to a plurality of sensing pads,
- wherein a maximum width of a first sensing line among the plurality of sensing lines is different from a maximum width of a second sensing line among the plurality of sensing lines.
