Abstract
A touch sensing device comprises touch electrodes having a first resolution for sensing touch in the active area. The touch sensing device also includes combination touch and fingerprint electrodes having a second resolution for sensing both touch and a fingerprint in the active area, the second higher than the first resolution. The touch sensing device also includes a touch and fingerprint controller that respectively applies a touch driving voltage for sensing touch to the plurality of touch electrodes and the plurality of combination touch and fingerprint electrodes during a touch driving mode of a touch period of the touch sensing device, and the touch and fingerprint controller applies a fingerprint driving voltage for sensing a fingerprint to the plurality of combination touch and fingerprint electrodes during a fingerprint mode of the touch period.
