[0023] Example one
[0024] Specifically, the stylus in this embodiment also includes a pen tip 40 for inputting to the touch screen of an electronic device. The pen tip 40 may be a capacitive pen tip or a resistive pen tip. The pen tip 40 is provided at the first end of the pen holder 10, when When the pen tip 40 is in contact with the touch screen, sliding the stylus can realize input to the touch screen, for example, drawing operations on the touch screen. In order to maintain the working state of the stylus, the stylus is provided with a built-in power source, for example, a replaceable battery is provided in the pen holder 10, and the battery is connected to the electrodes in the capacitive pen tip, so that the electrodes carry current. Of course, in other embodiments, the built-in power source may be a rechargeable battery.
[0025] As a preferred embodiment, the touch sensor 20 is a capacitive touch sensor 20, which includes a flexible circuit board and touch electrodes arranged on the flexible circuit board. The pen holder 10 in this embodiment is a cylindrical pen holder, and the flexible circuit board is fixed. On the side wall of the pen holder 10, in order to ensure the aesthetics of the pen holder 10, the flexible circuit board is completely attached to the side wall of the pen holder 10. The touch electrode is electrically connected to the signal transmitter 30, and the capacitance signal generated when the finger touches the touch electrode is transmitted to the electronic device through the signal transmitter 30. Further, the touch electrode includes a plurality of first electrodes and second electrodes distributed in a crisscross pattern. The first electrodes are distributed along the axial direction of the pen holder 10, and the second electrodes are distributed around the periphery of the pen holder 10, so that when the finger is touch-sensitive When sliding on the device 20, the touch information of each position of the finger on the touch sensor 20 can be detected, so that the movement of the pointer on the screen of the electronic device can be controlled in all directions. The first electrodes distributed along the axial direction correspond to the electrodes in the Y direction of the touch screen, and the second electrodes distributed along the circumferential direction correspond to the electrodes in the X direction of the touch screen.
[0026] Further, the aforementioned touch electrode distribution can be scaled down with respect to the electrode distribution of the touch screen on the electronic device, that is, the positions of the touch electrodes correspond to the positions on the electrodes of the touch screen in a one-to-one correspondence. In addition, the ratio of the sliding distance of the finger to the sliding distance of the screen pointer can be set according to the ratio of the touch electrode to the touch screen electrode. For example, the ratio of the touch electrode to the touch screen electrode is 1:100, and the sliding distance of the finger and the screen pointer can be set The ratio of 1:100, so that when the finger slides the touch sensor 20, the pointer on the touch screen can be accurately controlled. In addition, in addition to the function of moving the screen pointer, the touch sensor 20 can also be configured to collect information about finger clicks and finger double clicks. The finger click information is used to implement the screen pointer selection function, and the finger double click information is used To realize the confirmation function of the screen pointer.
[0027] Furthermore, a switch 60 is provided on the pen holder 10, and the switch 60 is electrically connected to the touch sensor 20, and is used to control the activation and deactivation of the touch sensor 20. When the pen tip 40 of the stylus is used to input the touch screen of the electronic device, the touch sensor 20 can be turned off by the switch, which can avoid accidentally touching the touch sensor 20 during use, and on the other hand, can save power.
[0028] Further, the stylus also includes a fingerprint recognition module 50, which is arranged on the pen holder 10 and is electrically connected to the signal transmitter 30, wherein the fingerprint information collected by the fingerprint recognition module 50 is transmitted to the electronic device through the signal transmitter to achieve Input to the electronic device, such as fingerprint unlocking of the electronic device. As a preferred embodiment, the fingerprint recognition module 50 is arranged at the second end of the pen holder 10, which on the one hand makes the appearance of the pen holder 10 more beautiful, and on the other hand, it can prevent accidentally touching the fingerprint recognition module 50 when performing other operations with the stylus. .
[0029] Such as figure 2 As shown, the electronic device kit in this embodiment includes an electronic device and the above-mentioned stylus. The electronic device has a touch screen and a signal receiver. The signal receiver and the signal transmitter 30 communicate through a wireless connection, wherein the wireless connection The method can be WIFI connection or Bluetooth connection or infrared connection. An accommodating slot 70 is also provided on the electronic device. The accommodating slot 70 is used for accommodating the stylus. On the one hand, it is convenient to carry the stylus, and on the other hand, it can prevent the stylus from being lost.
[0030] The stylus with touch function provided by the present invention, in addition to the input function to the touch screen of the electronic device, can also move the pointer on the screen by touching the touch sensor on the stylus, and the stylus is also provided There is a fingerprint recognition module, which can unlock the electronic device.
