Abstract
A touch screen driver includes a plurality of integrated circuits for dividedly driving a touch screen. One of the plurality of integrated circuits, which generates a driving signal to be supplied to Tx lines of the touch screen, 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 through Rx lines of the touch screen in response to the synchronization signal.

A touch screen driver driving a touch screen, which includes Tx lines, Rx lines and touch sensors formed at crossings of the Tx lines and the Rx lines, the touch screen driver comprising:
- a plurality of integrated circuits configured to dividedly drive the touch screen,
- wherein one of the plurality of integrated circuits, which generates a driving signal to be supplied to the Tx lines, transmits a synchronization signal synchronized with the driving signal to other integrated circuit,
- wherein the other integrated circuit receiving the synchronization signal receives charges of the touch sensors through the Rx lines in response to the synchronization signal.
