Abstract
A plurality of detection patterns are formed as conductive patterns directly on a back surface of a panel substrate to which an operation object such as a finger comes in proximity from a front surface side thereof. By independently detecting a change in capacitance in the plurality of detection patterns caused by proximity of the operation object from the front surface side, proximity of the operation object to the panel substrate is detected.
Claims20
A touch sensor comprising:
- a panel substrate to which an operation object including a finger comes in proximity from a front surface side thereof;
- and
- a detection pattern which is formed as a conductive pattern directly on a back surface of the panel substrate for detecting a change in capacitance.
A touch sensor comprising:
- a panel substrate to which an operation object comes in proximity from a front surface side thereof;
- a detection pattern which is formed as a conductive pattern directly on a back surface of the panel substrate for detecting a change in capacitance.
- a connector which is connected to the detection pattern for externally connecting the detection pattern and provided on the back surface side of the panel substrate.
A touch sensor comprising:
- a panel substrate to which an operation object including a finger comes in proximity from a front surface side thereof;
- and
- a plurality of detection patterns which are formed as conductive patterns directly on a back surface of the panel substrate for respectively detecting a change in capacitance independently from each other.
