1. A touch sensor apparatus comprising:
a multiplexer including a first transistor connected to a first touch sensor and a second transistor connected to a second touch sensor;
a touch driver connected to the first touch sensor through the first transistor, and connected to the second touch sensor through the second transistor;
wherein,
the first touch sensor is disposed at a first distance from the touch driver,
the second touch sensor is disposed at a second distance shorter than the first distance from the touch driver, and a first on-resistance of the first transistor is less than a second on-resistance of the second transistor,
wherein the touch driver applies a first control voltage based on the first distance to the first transistor and applies a second other control voltage based on the second distance to the second transistor.
