Publication number: 20150022493Abstract: A touch pen includes a power supply circuit, a signal-receiving electrode, a noise-sensing electrode, an inverted amplifying circuit, and a signal-emitting electrode. The power supply circuit provides the touch pen with a working voltage, the signal-receiving electrode receiving at least one surface signal of a touch-sensing electrode structure of a capacitive touch-sensitive device, and the noise-sensing electrode receives at least one ambient noise signal.
