Title:
ACTIVE CAPACITIVE STYLUS APPLIED TO INTELLIGENT TERMINAL, AND TOUCH DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/051669
Kind Code:
A1
Abstract:
An active capacitive stylus (100) applied to an intelligent terminal, and a touch device (1000). The active capacitive stylus (100) comprises a conductive nib (11), a shell body (12), and a cartridge assembly (13). The cartridge assembly (13) comprises a pressure sensor (14), a microcontroller (15), a charging interface (17), and an electrochemical capacitor (18). The conductive nib (11) is used for detecting a touch signal when being in contact with a touch screen, and emitting a feedback signal outputted by the microcontroller (15). The pressure sensor (14) is used for detecting the touch pressure of the conductive nib (11). The microcontroller (15) is used for receiving and processing the touch signal to generate a synchronous feedback signal. The charging interface (17) charges the active capacitive stylus (100) when connected to the intelligent terminal. The electrochemical capacitor (18) is used for storing power and supplying power to the active capacitive stylus (100). The active capacitive stylus (100) adjusts an original lithium battery and dry battery into a super-capacitor; the super-capacitor is small in size, and the active capacitive stylus is thinner, and thus, the user experience is better; furthermore, using a charging contact for charging is convenient, and the charging time is short, thereby facilitating an interactive mode of the whole machine, and also playing a role in low-carbon environmental protection.
