DRIVING AND SENSING METHOD FOR TOUCH-SENSING INPUT DEVICE, AND MODULE USING THE SAME |
摘要 |
The disclosure provides a driving and sensing method for a touch-sensing input device including a touch-sensing panel module and a liquid crystal display panel module. The touch-sensing panel module includes a touch-sensing panel and a control device, wherein the touch-sensing panel includes a plurality of X-directional lines and Y-directional lines arranged intersecting one another. The method includes steps of generating a spread spectrum clock signal using the control device; generating a driving signal and a sensing signal based on the spread spectrum clock signal; outputting the driving signal to one of the X-directional lines or one of the Y-directional lines; receiving voltages on the corresponding Y-directional line or X-directional line in response to the sensing signal and converting the same to a digital signal; and determining a touch status of the touch-sensing panel based on the digital signal.
