Driving and sensing method for touch-sensing input device, and module using the same

A driving and sensing module applied in a touch-sensing input device, the touch-sensing input device comprising a touch-sensing panel module and a liquid crystal display panel module, the touch-sensing panel module comprising a touch-sensing panel and the driving and sensing module, wherein the touch-sensing panel comprises a plurality of first-directional lines and a plurality of second-directional lines, and the first-directional lines and the second-directional lines are arranged intersecting one another, the driving and sensing module comprising:

• a spread spectrum clock generator, configured to generate a spread spectrum clock signal;
• a selection module, configured to select a scan line and a sense line of each scanning operation from the first-directional lines and the second-directional lines;
• a driving signal generation circuit, configured to generate a driving signal applied to the scan line selected during each scanning operation by the selection module based on the spread spectrum clock signal;
• an analog to digital conversion module, configured to receive voltages on the sense line selected during each scanning operation by the selection module based on the spread spectrum clock signal, and further configured to convert the voltages to a digital signal;
• and
• a signal processing unit, configured to calculate a touch status of the touch-sensing panel based on the digital signal output from the analog to digital conversion module.
