A touch screen driver (30) includes a plurality of integrated circuits for dividedly driving a touch screen (TSP). One of the plurality of integrated circuits, which generates a driving signal to be supplied to Tx lines of the touch screen (TSP), transmits a synchronization signal synchronized with the driving signal to other integrated circuit. The other integrated circuit receiving the synchronization signal receives charges of the touch sensors (TSN) through Rx lines of the touch screen (TSP) in response to the synchronization signal. |
