Title:
REAL HANDWRITING STYLUS AND TOUCH DEVICE HAVING RADIO FREQUENCY TRANSMITTING AND RECEIVING FUNCTION
Document Type and Number:
WIPO Patent Application WO/2017/185735
Kind Code:
A1
Abstract:
Disclosed in the present invention are a real handwriting stylus and a touch device, comprising: a stylus casing, a battery within the stylus casing, a stylus system circuit within the stylus casing, a stylus touch pressure sensing assembly within the stylus casing and a touch module. The stylus touch pressure sensing assembly comprises a nib, a nib touch switch and a nib pressure sensor. The stylus system circuit comprises a charging circuit, a power control and delayed turn-off circuit, a power voltage conversion circuit, a function key, a radio frequency modulation and radio frequency transmitting and receiving circuit and a stylus signal generation circuit. The radio frequency modulation and radio frequency transmitting and receiving circuit is connected to the nib pressure sensor and the function key to acquire a nib pressure signal and a function key signal, and outputs a radio frequency modulation signal after radio frequency modulation. The radio frequency modulation and radio frequency transmitting and receiving circuit can receive a frequency hopping command radio frequency signal of the touch assembly, and output a frequency hopping signal to the stylus signal generation circuit. The stylus signal generation circuit is connected to the radio frequency modulation and transmitting and receiving circuit to acquire the frequency hopping signal so as to perform a frequency hopping operation. The stylus and the touch device, consisting of the stylus and the touch module of the present invention, have strong anti-interference characteristics and give the effect of real handwriting, and any shortcut key function can be defined for the function key thereof at a peripheral end.
