Embodiment 1

[0052] The embodiment of the present invention provides a kind of stylus, refer to figure 1 As shown, the stylus includes:

[0053] The capacitor unit 10 has different capacitance values ​​when the stylus is at different inclination angles.

[0054] It should be noted that the reference figure 2 As shown, the central axis NM of the stylus 1 forms an angle θ with the plane ABCD contacted by the stylus 1 , and the angle θ is the inclination angle of the stylus. When the posture of holding the pen is different, the size of the included angle θ will change accordingly, and the stylus will also be at different inclination angles accordingly. The included angle θ ranges from 0° to 90°. The specific structure of the capacitor unit is not limited here, as long as it has different capacitance values ​​when the stylus is at different inclination angles.

[0055] The detection unit 11 is connected to the capacitance unit, and is used to detect the capacitance of the capacitance unit...

The invention provides a stylus, a driving method of the stylus and a touch system, relates to the technical field of touch, and aims to provide a novel stylus for improving the writing experience ofthe stylus. The stylus includes: a capacitance unit having different capacitance values when the stylus is at different tilt angles; a detection unit connected with the capacitor unit and used for detecting the capacitance value of the capacitor unit and generating capacitance information; a signal generation unit connected with the detection unit and used for generating a corresponding driving signal according to the capacitance information; the capacitance unit, the detection unit and the signal generation unit are all arranged in a pen body of the stylus. The invention is suitable for the stylus and the touch system comprising the stylus.

Description

technical field [0001] The invention relates to the field of touch technology, in particular to a touch pen, a driving method thereof, and a touch system. Background technique [0002] With the development of touch technology, more and more electronic devices adopt touch mode for human-computer interaction. Active stylus is a frequently used tool for human-computer interaction. The working principle of the current active stylus is based on the fact that when writing, the screen of the electronic device will transmit a certain pressure to the pen core, and the pressure detection device installed inside the pen core receives the pressure and processes it. The processed pressure signal is then sent to the screen of the electronic device through the conductive component through the pen core, and then coupled with the capacitance at the screen end, so that the written content is displayed on the screen of the electronic device. [0003] However, with the development of touch te...
