Abstract: A stylus pen that includes a tip electrode, a power supply circuit, a signal detector, and a drive circuit where an output signal is transmitted to and an input signal is received from a touch panel via the tip electrode. The power supply circuit of the stylus pen selectively supplies a first supply voltage or a second supply voltage. The signal detector of the stylus pen detects an enable signal from the input signal and the signal detector of the stylus pen controls the power supply circuit to supply the first supply voltage in response to presence of the enable signal. The drive circuit operates at the first supply voltage to generate the output signal.

Abstract: A detection device and method for touch panel are provided. The device includes a wiring module configured to ground lead of at least one of first touch electrodes; and a processing module configured to detect capacitance value of at least one of second touch electrodes one by one, and determine whether the second touch electrode is broken circuit according to the capacitance value of each of the second touch electrodes which is adjacent to at least one of the first touch electrodes. During detection, the at least one first touch electrode is grounded, and the second touch electrode and the first touch electrode with a lead grounded form a capacitor. If the second touch electrode is not broken circuit, the capacitance value detected is greater than the capacitance value when the first touch electrode is not grounded. It is beneficial for detecting accurately whether the touch electrode is broken circuit.
