Abstract
A touch panel includes a first touch electrode and a second touch electrode disposed on a substrate; a common electrode that receives a common voltage that is a reference for a voltage transmitted to the first and second touch electrodes; a first touch wiring and a second touch wiring respectively connected to the first touch electrode and the second touch electrode; and a touch driver that transmits a driving signal to the first and second touch wirings.
Claims24
A touch panel, comprising:
- a first touch electrode and a second touch electrode disposed on a substrate;
- a common electrode that receives a common voltage that is a reference for a voltage transmitted to the first and second touch electrodes;
- a first touch wiring and a second touch wiring respectively connected to the first touch electrode and the second touch electrode;
- and
- a touch driver that transmits a first voltage to the first touch electrode through the first touch wiring, and transmits a second voltage to the second touch electrode through the second touch wiring,
- wherein:
- the first voltage is greater than the common voltage, and
- the second voltage is less than the common voltage.
