Abstract
A touch screen apparatus and a driving method thereof are provided. The touch screen drive circuit performs a setup operation for selecting Tx lines to be supplied with the drive signal and Rx lines to receive the voltages of the touch sensors, a sensing operation for supplying a drive signal to the Tx lines and receiving and sampling touch sensor voltages through the Rx lines, an ADC operation for converting the sampled voltages into digital data, a coordinate detection operation for analyzing the digital data by a preset touch detection algorithm and estimating the coordinates of a touch input position, and a data transmission operation for transmitting touch coordinate data comprising the coordinates to an external system. At least two operations among the setup operation, the sensing operation, and the ADC operation are performed in parallel.
