PURPOSE: A touch screen operating device and a method thereof are provided to minimize sensing time and the number of sensing times by virtually dividing a touch screen into blocks, determining touch input by block, designating a partial sensing area including a touch input position, and precisely sensing the touch input position. CONSTITUTION: A touch screen(TSP) includes Tx lines, Rx lines crossing the Tx lines, and a touch recognizable area including sensor nodes(TSN) formed on a crossing part between the Tx lines and Rx lines. A touch screen operating circuit detects touch input to primary blocks divided in the touch recognizable area. The touch screen operating circuit detects touch input to secondary blocks divided in the primary blocks. The touch screen operating circuit precisely senses the touch input in the secondary blocks. |
