Abstract
A touch sensor controller for driving a touch sensor that is stacked on a display panel and includes driving electrodes and receiving electrodes crossing the driving electrodes, the touch sensor controller including: a driving circuit configured to sequentially provide driving signals to the driving electrodes; a read-out circuit configured to, in response to the driving signals, generate touch data based on first sensing signals received from the receiving electrodes and generate display noise data based on a second sensing signal received from a first driving electrode to which a driving signal of the driving signals is not applied from among the driving electrodes; and a touch processor configured to determine whether a touch input has occurred on the touch sensor based on the touch data and the display noise data.
