摘要： 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.

摘要： A touch sensing device includes a touch screen including Tx lines, Rx lines crossing the Tx lines, and touch sensors formed between the Tx lines and the Rx lines, and a touch screen driving circuit which senses all the touch sensors of the touch screen in a first sensing step to detect the presence or absence of a touch input, and then again senses the touch sensors, in which the touch input is detected as a first sensing result, in a second sensing step to detect a position of the touch input. When there is no touch sensor, in which the touch input is detected as the first sensing result, the touch screen driving circuit repeats the first sensing step.
