Abstract
A touch system includes a touch panel having first electrodes formed in a first direction, second electrodes formed in a second direction, and driving lines and pre-charge lines connected to respective first electrodes; and a touch IC unit configured to successively apply driving signals to the first electrodes, receive sensing signals through the second electrodes, and, when applying the driving signal to a driving line connected to a first electrode chosen as a driving electrode from the first electrodes, apply a pre-charge signal to a pre-charge line connected to at least one first electrode chosen as a pre-driving electrode from the other first electrodes than the first electrode chosen as the driving electrode.
