Abstract
A touch sensing system and a driving method thereof are provided. The touch sensing system includes: a touch screen drive circuit which senses a change in the amount of electric charge in touch sensors during a sensing period, generates raw data and temporarily stores it in a buffer memory, transmits the raw data read out from the buffer memory to an algorithm execution unit during a raw data transmission period, and calculates the coordinates of touch input by the algorithm execution unit during an algorithm execution period. The touch screen drive circuit controls the amount of data stored in the buffer memory and the start timing of a read operation to make the sensing period and the raw data transmission period overlap each other.
