Abstract:
A low power driving and sensing system for capacitive touch panels includes a capacitive touch panel, a first switch device, a second switch device, a driving device, a sensing device, and a control device. The capacitive touch panel has plural first conductor lines arranged in a first direction and plural second conductor lines arranged in a second direction. The driving device is connected to the first switch device for driving the capacitive touch panel. The sensing device is connected to the second switch device for sensing the capacitive touch panel. The control device configures the first switch device and the second switch device for entering the capacitive touch panel into a self-capacitance mode such that the driving device and the sensing device perform a self capacitance sensing, and into a mutual capacitance mode such that the driving device and the sensing device perform a mutual capacitance sensing.
