Touch pen and mobile-terminal touch pen status detection device and method

Abstract

The invention discloses a touch pen and a mobile-terminal touch pen status detection device and method. The mobile-terminal touch pen status detection device comprises a touch pen fixation position, a Hall detection chip and a control chip; the touch pen fixation position is arranged on one side along the mobile terminal and is used for placing the touch pen with the magnetic structure; the Hall detection chip is arranged in the mobile terminal and is used for detecting change of magnetic field and generating corresponding detection signals when change of the magnetic field is detected; the control chip is connected with the Hall detection chip and is used for receiving the detection signals generated from the Hall detection chip and forming corresponding control instructions according to the detection signals, and the control instructions correspond to function operations of the mobile terminal. Use condition of the mobile-terminal touch pen is judged through detection of the status of the touch pen pulled out from or plugged in the accommodating position, automatic functional responses of the mobile terminal are performed, and convenience is brought to users.

Description

technical field [0001] The invention relates to the technical field of mobile terminals, in particular to a mobile terminal stylus state detection device, a detection method and a stylus. Background technique [0002] With the rapid development of science and technology, many electronic devices use touch panels as operation interfaces, such as large-screen capacitive screen mobile phones, tablet computers and other mobile terminals, so that users can operate by touch to improve convenience. In order to make the process of operating the touch panel faster and more accurate, most users will use a stylus for touch input, and people's demand for the stylus is also increasing. [0003] Please refer to figure 1 , is a schematic diagram of using a stylus to control a mobile terminal in the prior art. The stylus 103 can directly write on the touch screen 102 of the mobile terminal 101, and can also perform operations such as single click, double click, and drag. It can simulate w...

AI Technical Summary

Problems solved by technology

When using the active stylus, the user usually needs to pull out the stylus from the protective case, and then operate the mobile terminal after turning on the stylus to make the two paired; It is necessary to turn off the touch function of the mobile terminal to reduce power consumption, which makes the use of the stylus more troublesome
