Abstract
A touch sensor includes: a plurality of electrodes; and a plurality of sensing wires connected with the respective electrodes, and formed by extending in a first direction, wherein at least one of the electrodes includes a resistance element which has a shape that is at least partially bent in a unit electrode region and has a resistance value that is changed to correspond to a pressure of a touch. A touch location and pressure can be sensed with the same elements, so that the touch sensor may have increased function yet remain thin.
Claims22
A touch sensor, comprising:
- a plurality of electrodes;
- and
- a plurality of sensing wires connected to the electrodes and extending in a first direction,
- wherein at least one of the electrodes comprises a resistance element having a shape that is at least partially bent in a unit electrode region and a resistance value that changes in response to a pressure of a touch.
A touch sensor, comprising:
- a plurality of electrodes;
- and
- a plurality of sensing wires connected to the electrodes and extending in a first direction,
- wherein at least one of the electrodes comprises a first resistance element that has a zigzag pattern and has a resistance value that changes in response to a pressure of a touch.
A touch sensor, comprising:
- a plurality of first electrodes arranged in a first direction;
- a plurality of second electrodes arranged in a second direction that is perpendicular to the first direction, to form mutual-capacitance together with an adjacent first electrode;
- a plurality of first connectors configured to connect the first electrodes;
- and
- a plurality of second connectors configured to connect the second electrodes,
- wherein at least one of the first and second electrodes and the first and second connectors comprises a resistance element having a zigzag pattern.
