Abstract
A touch sensing system and a method of reducing latency thereof are disclosed. The touch sensing system includes a touch sensing circuit configured to apply a driving signal to touch sensors, sense voltages of the touch sensors, and output a digital touch raw data; a coordinate calculator configured to analyze the digital touch raw data, and calculate a coordinate information about each of positions of a touch input; and an idle mode controller configured to compare an analog signal received from the touch sensors with a predetermined threshold value, decide whether or not the touch input is generated based on the analog signal, and generate an interrupt signal when the touch input is sensed.
