Of course, after the stylus is connected with the electronic device every time, the stylus can also record and store the coding time of each time, when the stylus is connected with the electronic device again next time, the last coding time of the connected pen point can be sent to the electronic device, and after the electronic device receives the writing time of each time of the pen point sent by the stylus, the electronic device side records and stores the coding time.

After the electronic equipment acquires the accumulated service life of the pen point, whether the prompt condition of the service life of the pen point is met or not can be determined according to the accumulated service life of the pen point and a preset service threshold. The preset threshold may be set according to a test life value of the pen tip, and is used to indicate an accumulated use duration threshold of the pen tip when the service life of the pen tip of the stylus reaches a preset life critical point, where the accumulated use duration threshold may be stored in the electronic device in advance or read from the stylus, and is not limited herein. Optionally, specifically, when determining whether the prompt condition of the pen tip life is satisfied, the determination may be performed according to a difference between the preset use threshold and the accumulated use duration of the pen tip, for example, when the difference between the preset use threshold and the accumulated use duration of the pen tip is smaller than the preset prompt difference, the prompt condition of the pen tip life may be considered to be satisfied, otherwise, the prompt condition of the pen tip life may be considered to be not satisfied. Optionally, the preset prompt difference may be any value such as 5 hours, 8 hours, 10 hours, and the like, which is not limited herein, and may be flexibly adjusted according to an actual application scenario. Of course, according to the actual application scenario, it may also be determined whether the accumulated service life of the pen tip is equal to the preset service threshold, and if so, it may be considered that the prompt condition of the pen tip life is satisfied, otherwise, it may be considered that the prompt condition is not satisfied.

In some embodiments, the prompt window is displayed in the form of a prompt window, and when the prompt condition is met, the prompt window is generated and displayed on the current interface, as shown in fig. 5, the prompt window 203 may be displayed on any current interface of the electronic device (for example, the prompt window may pop up and be displayed on the current interface in an overlapping manner). For example, the content displayed in the prompt window 203 may be preset text content, for example: "expect the stylus tip BJA _001 to be able to write for 2 hours, please change the tip in time! "where BJA _001 is a pen tip identifier, optionally, in order to facilitate a user to intuitively know a type of a pen tip, a preset number of digits in the pen tip identifier may be used to indicate a pen tip type, and other digits are a pen tip serial number, which may uniquely identify the pen tip, and currently, an actual identification manner is not limited thereto. Referring to fig. 5, the third bit (i.e., a) in the nib identifier may be used to indicate a nib type, that is, it can be seen from the nib identifier that the nib type to which the nib belongs is the a type, optionally, the a type may indicate that the nib is a conductive soft rubber type nib, of course, besides the a type, the practical application scenario may also include the B type, and the B type may indicate that the nib is a plastic type nib with a softer material, and of course, the specific classification and the identification manner are not limited thereto. In addition, the content displayed in the prompt window 203 may further include a voice broadcast, a preset animation, and the like, which is not limited herein. The 'continuous writing time of 2 hours' is used as the expected continuous writing time, and can be determined according to the accumulated use time of the pen point and the preset use threshold corresponding to the pen point, and when the determination is specifically made, the accumulated use time of the pen point can be subtracted from the preset use threshold corresponding to the pen point, so that the remaining continuous writing time of the pen point can be obtained.

Referring to the stylus pen tip BJA _001 shown in fig. 5 as an example, if the accumulated pen tip usage time of the pen tip BJA _001 read by the electronic device is 98 hours, the preset usage threshold corresponding to the pen tip BJA _001 is 100 hours, and the preset prompt difference is 2.5 hours, then the pen tip BJA _001 can be calculated to continuously write for 2 hours (100 hours-98 hours is 2 hours), and it can be seen that the calculated expected continuous writing time (2 hours) of the pen tip is smaller than the preset prompt difference (2.5 hours), in this case, a "the expected stylus pen tip BJA _001 can continuously write for 2 hours" is displayed in the prompt window 203, and the pen tip is required to be replaced in time |! The service life of the pen point is prompted, so that a user can replace the pen point in time according to the service life of the pen point. Wherein, different types of nibs can correspond different preset usage thresholds.

Optionally, the current interface may be a main interface of the electronic device, or may be a user interface of any application, which is not limited herein.

In some embodiments, when displayed by the stylus application, that is, the corresponding management application may be downloaded and installed for the stylus, and the application records information related to the stylus, and completes pushing of the prompt information, and the like. Referring to fig. 6, the management account number may be a phone number of the user, and may be displayed through an information management interface 204 preset in the stylus application, specifically, a management account number corresponding to the stylus may be logged in through the stylus application, as can be seen from fig. 6: 131XXXX001, in the information management interface 204, stylus-related management information may be displayed, which may include but is not limited to: the pen nib identifier is a pointer that can be used to indicate the current pen nib type, the current pen nib identifier, the cumulative usage time of the connected pen nib, the expected continuous writing time of the connected pen nib, and the like. Of course, the specific display content is not limited to this, and may further include: the connectable mode of the stylus and the electronic device, and the like. The predicted continuous writing time of the connected pen tip can be referred to the related parts, and the details are not repeated herein.

In addition, if the user has multiple touch pens, a corresponding management account may also be established for each touch pen, and the management account corresponding to the touch pen may also be a touch pen identifier, a brand model, and the like, which is not limited herein. In some embodiments, since the pen tip is replaceable in the stylus pen, the stylus pen identifier may be a pen holder identifier, and the pen holder identifier may be a production serial number corresponding to the pen holder, or may be composed of the pen tip identifier and the pen holder identifier, which is not limited herein. Based on this description, it can be seen from fig. 6 that the stylus has been historically connected to two electronic devices, PAD _01 and PAD _02, the current power of the stylus is 83%, the connection of the type a and type B tips can be supported, the currently connected tip is type a, and the tip is identified as BJA _001, the current accumulated usage time of the tip BJA _001 is 98 hours, and the expected usage time is 2 hours. The accumulated usage duration may be a sum of usage times of the electronic devices connected in history.

Fig. 7 is an interactive schematic view of another method for prompting a pen tip life of a stylus according to an embodiment of the present application, and referring to fig. 7, the step of reading a cumulative service life of a pen tip of a connected stylus may include:

s201, the touch pen obtains each coding time of the pen point and sends the coding time to the electronic equipment.

S202, the electronic equipment receives the coding time of each time of the pen point sent by the touch pen, and the accumulated using time of the pen point of the touch pen is calculated and recorded according to the coding time of each time of the pen point.

In some embodiments, the time per coding of the pen tip is the time per writing of the pen tip, wherein the time per coding of the pen tip may refer to the continuous writing time of the pen tip during each connection of the stylus to the electronic device.

Alternatively, the stylus may obtain each coding time of the pen tip by: the stylus pen can be internally provided with a pressure sensor which can be a strain type pressure sensor, strain materials in the strain type pressure sensor can be deformed in the writing process of the stylus pen, the deformation of the strain materials can be transmitted to the main circuit board (for example, the strain type pressure sensor and the main circuit board can be electrically connected through a lead or a flexible circuit board), the main circuit board can detect the pressure of the writing end of the pen point according to the deformation of the strain materials, and therefore the time of each time of code printing of the pen point can be obtained according to the duration of the pressure.

After the stylus acquires the coding time of the pen point every time, the coding time of the pen point every time can be sent to the electronic equipment, and after the electronic equipment receives the coding time of the pen point every time sent by the stylus, the coding time of the pen point can be calculated and summed, so that the accumulated service life of the pen point of the stylus can be acquired.

In an optional embodiment, during the writing process of the stylus, the thickness of the line at the writing end can also be controlled according to the pressure at the writing end of the pen tip, wherein the larger the pressure is, the thicker the line written by the writing end is, and the smaller the pressure is, the thinner the line written by the writing end is.

It should be noted that, in some embodiments, the pressure sensor may also be: the piezoresistive pressure sensor, the ceramic pressure sensor, the diffused silicon pressure sensor and the like are not limited herein, and can be flexibly arranged according to actual application scenes. Referring to fig. 3, the pressure sensor may be disposed in the pen tip 10 or the pen barrel 20 of the stylus 100, and the present application is not limited to a specific disposition position. Optionally, when the pressure sensor is disposed in the shaft 20 of the stylus 100, after one end (i.e., the writing end) of the pen tip 10 of the stylus 100 is stressed, the other end of the pen tip 10 moves to apply force to the pressure sensor, and at this time, the stylus can obtain each coding time of the pen tip through the pressure acquired by the pressure sensor. Of course, the detection method for detecting the pressure applied to the writing end of the stylus is not limited thereto.

In another embodiment of transmitting the coding time, considering that the power consumption of the stylus may increase if the stylus is configured to send each coding time to the electronic device in real time, in some embodiments, the stylus may send each coding time of the pen point in the stylus to the electronic device in a first preset period according to a first preset period (e.g., 0.5 hour, 2 hours, and the like), and after the electronic device receives each coding time of the pen point in the stylus in each first preset period, the pen point identifications may be correspondingly stored and summed to obtain the accumulated use time of the pen point of the stylus. When the stylus transmits each coding time of a pen point in the stylus to the electronic device in each first preset period, the coding time can be directly transmitted or indirectly transmitted.

In another embodiment, after the user finishes using the electronic device each time, for example, after the user stops using the electronic device for a time period longer than a preset time period (1 minute or 5 minutes), the touch pen may send the code printing time used this time to the electronic device.

Referring to fig. 2, the indirect sending means that the stylus needs to send the recorded accumulated pen tip usage time to other external devices (e.g., a wireless keyboard 300, a pen container 400, a pen holder, etc.) first, and then forward the recorded code printing time to the electronic device through the connection between the other external devices and the electronic device; the recorded time of the code is sent to the electronic device directly, that is, the stylus pen does not send the recorded time of the code to other external devices but directly sends the recorded time of the code to the electronic device according to a communication link between the stylus pen and the electronic device.

Optionally, if the stylus has a function of calculating and recording the accumulated time of use of the pen tip, the stylus may calculate and record the accumulated time of use of the pen tip according to the time of coding each time of the pen tip, and send the recorded accumulated time of use of the pen tip to the electronic device. Optionally, the stylus pen may send the recorded nib cumulative usage duration to the electronic device, where the sending may be direct sending or indirect sending, and similarly, as shown in fig. 2, the indirect sending is that the stylus pen needs to send the recorded nib cumulative usage duration to other external devices (for example, the wireless keyboard 300, the pen container 400, the pen holder, and the like) first, and then forward the recorded nib cumulative usage duration to the electronic device through the connection between the other external devices and the electronic device; and directly sending the recorded accumulated pen point use duration to the electronic equipment, namely, the stylus pen directly sends the recorded accumulated pen point use duration to the electronic equipment according to the communication connection between the stylus pen and the electronic equipment without passing through other external equipment. In addition, the sending time of the stylus pen is not limited in the present application, the sending time of the stylus pen may be actively sent each time a communication connection is established with the electronic device, or the recorded accumulated pen tip duration may be actively sent to the electronic device periodically according to a second preset period (for example, 2 hours, 4 hours, and the like), or the sending time may be passively sent according to a pen tip accumulated usage duration obtaining request sent by a user, and optionally, the user may send the pen tip accumulated usage duration obtaining request to the stylus pen through a stylus application program on the electronic device, where the sending of the pen tip accumulated usage duration obtaining request by the stylus pen may include: stylus identification, nib identification, and the like.

In summary, the embodiment of the present application does not limit the sending manner and sending time for sending the recorded accumulated pen tip usage duration to the electronic device by the stylus pen, and can be flexibly set according to the actual application scenario. Based on the above description, it can be understood that, if the recorded accumulated pen point usage duration is sent to the electronic device by the stylus, a problem that when a user uses the same stylus to use different electronic devices, each electronic device can only record the accumulated pen point usage duration of the pen point of the stylus on the electronic device, which results in that the finally obtained accumulated pen point usage duration of the stylus is not accurate enough can be avoided.

Based on the above description, in some embodiments, considering that a user may use the same stylus pen on different electronic devices, optionally, the electronic device may send the latest calculated pen point cumulative usage duration to the stylus pen according to a third preset period (e.g., 1 hour, 3 hours, etc.), so that when the stylus pen is in communication connection with other electronic devices, the stylus pen may synchronously forward the latest pen point cumulative usage duration sent by the last electronic device to the other electronic devices, and accordingly, the other electronic devices may obtain the latest pen point cumulative usage duration, and further perform continuous accumulation based on the latest pen point cumulative usage duration, so as to obtain a more accurate pen point cumulative usage duration of the stylus pen.

In addition, in some embodiments, if the user can also log in a management account corresponding to the stylus through the electronic device, the electronic device can update the latest calculated accumulated nib use duration to the management account corresponding to the stylus in real time, so that when the user uses the same stylus on different electronic devices, the latest accumulated nib use duration can be obtained in real time and synchronized by logging in the management account corresponding to the stylus on each electronic device.

Furthermore, considering that different users write with the stylus pen under different pressures, for example, a part of users may write with the stylus pen with a light pressing force degree or a heavy pressing force degree, where if the pressing force degree of a certain user writing with the stylus pen is lower than a preset pressing force degree range, the pressing force degree of the user may be considered to be light; otherwise, if the pressing force is higher than the preset pressing force, the pressing force of the user may be considered to be heavier, alternatively, the preset pressing force range may be a preset average pressing force range, which may be obtained by counting the pressing force when a plurality of users write with the stylus pen, or may be set according to experience, which is not limited herein.

Based on the description, it can be understood that, since the pressing force of the stylus pen used by different users is different, for example, if the pressing force is less when a user uses the stylus pen to write, even if the accumulated using time of the pen tip reading the stylus pen used by the user is greater than the preset using threshold, but in practice, the pen point of the stylus is not worn seriously, that is, the pen point of the stylus does not reach the critical point of the life span of the pen point, or if the pressing force is heavy when a user uses the stylus to write, although the accumulated using time of the pen point of the touch pen used by the user is read to be less than the preset using threshold at a certain time, but in practice, the pen point of the touch control pen is worn seriously, that is, the pen point of the touch control pen reaches the service life critical point of the pen point before the prompting time of the prompting information, in order to prompt the user more accurately, the judgment condition is added before judging whether the prompt condition is met.

Fig. 8 is a schematic flow chart of another method for prompting a pen tip life of a stylus according to an embodiment of the present disclosure, in this embodiment, based on that a pen tip electrode may be used to emit an electrode signal during a writing process of the stylus, and when the pen tip electrode is close to a touch screen of an electronic device, a coupling capacitor may be formed between the pen tip electrode and the touch screen of the electronic device, so that the electronic device may receive the electrode signal. Referring to fig. 8, in the method, before reading the accumulated use duration of the pen tip of the connected stylus pen, the method may include:

s301, detecting and acquiring an electrode signal generated according to a stylus tip electrode.

S302, if the signal quantity of the electrode signal generated by the stylus tip electrode is larger than a first threshold value, reading the accumulated use time of the stylus tip of the connected stylus.

And S303, determining whether a prompt condition is met or not according to the accumulated service life of the pen point and a preset service threshold, and if the prompt condition is met, generating and displaying service life prompt information of the pen point.

Wherein, when the electronic device acquires an electrode signal generated by a stylus tip electrode, it can determine whether the signal quantity of the electrode signal is greater than a first threshold, if so, it indicates that the wear of the stylus tip of the stylus reaches the wear quantity corresponding to the critical point of the stylus tip life, that is, the stylus tip of the stylus is worn seriously, at this time, the accumulated pen tip usage duration of the connected stylus can be read, and it is further determined whether the accumulated pen tip usage duration is greater than a preset usage threshold, and if so, it indicates that the accumulated pen tip usage duration of the stylus has also reached the threshold of the accumulated pen tip usage duration corresponding to the critical point of the stylus tip life, it can be understood that, in this case, it indicates that the pen tip of the stylus has reached the critical point of the stylus tip life in two dimensions from the wear quantity and the accumulated pen tip usage duration, and then the generated pen tip life prompt information has the characteristic of accurate prompt, the pen point has the advantages that the user can be reminded of timely replacement when the pen point of the touch control pen reaches the critical point of the service life of the pen point, the writing efficiency and the writing effect of the user are guaranteed, and the use experience of the user is improved.

The first threshold may represent a signal threshold corresponding to an electrode signal generated by a stylus tip electrode when a nib wear amount of the stylus reaches a wear amount corresponding to a nib life critical point. Alternatively, the wear amount corresponding to the pen tip life critical point may be any value from 1/4 to 1/3 of the size (e.g., diameter, area, etc.) of the reference pen tip, for example, the wear amount corresponding to the pen tip life critical point of a certain type of pen tip is 1/3 of the reference pen tip diameter of the type, and then the first threshold corresponding to the type of pen tip is a signal amount threshold corresponding to an electrode signal generated by the reference pen tip electrode when the reference pen tip diameter is 2/3 (where 1/3 of the reference pen tip diameter is worn), where the reference pen tip is an unused, brand new pen tip. The more the pen point of the stylus is worn, the larger the signal quantity of the electrode signal generated by the stylus pen point electrode is, and otherwise, the smaller the signal quantity of the electrode signal generated by the stylus pen point electrode is. Of course, the correspondence between the signal amount of the electrode signal generated by the stylus tip electrode and the degree of wear of the stylus tip is not limited thereto. Alternatively, the semaphore of the electrode signal may be acquired through an Analog to Digital Converter (ADC) built in the electronic device.

For example, if the first threshold is a and the electrode signal generated by the tip electrode of the stylus pen is B, then if the value of a is 4000 and the value of B is 4800, it can be seen that, at this time, the signal amount (i.e. 4800) of the electrode signal generated by the tip electrode of the stylus pen is greater than the first threshold (i.e. 4000), in this case, the electronic device may read the cumulative service time of the nib of the connected stylus pen, wherein, if the cumulative service time of the nib at a certain time is 50 hours, the preset service threshold corresponding to the nib is 100 hours, and the preset prompt difference is 2.5 hours, then the expected writing time of the nib may be calculated to be 50 hours (100 hours-50 hours are 50 hours), and it can be seen that, at this time, the calculated expected writing time (50 hours) of the nib may be greater than the preset prompt difference (2.5 hours), when the prompt condition is not met, the electronic equipment does not display the pen point service life prompt information, so that the interference of invalid pen point service life prompt information on a user is avoided; if the electronic device reads that the accumulated use time of the pen point is 98 hours at another moment, it can be seen that the calculated expected continuous writing time (2 hours to 100 hours to 98 hours) of the pen point is less than the preset prompt difference (2.5 hours) and meets the prompt condition, and then the pen point service life prompt information can be generated and displayed. The values of a and B are not limited to the above examples, and may be flexibly set according to the actual application scenario and the type of the pen tip.

Fig. 9 is a schematic diagram illustrating tip replacement of a stylus according to an embodiment of the present disclosure. The type of the pen tip 10 in the stylus pen 100 is not limited herein, and optionally, as shown in fig. 9, different types of pen tips may be connected to the same pen barrel, for example, a conductive soft rubber type pen tip 11 may be connected, or a softer plastic type pen tip 12 may be connected, which is not limited herein and may be flexibly replaced according to an actual application scenario. Of course, it should be noted that different types of pen points may correspond to different pen point type identifiers, so that after the user replaces the pen point, the electronic device may acquire the pen point type identifier after being in communication connection with the stylus pen, and may also record and prompt the user to replace another type of pen point, adjust the writing mode, and improve the user experience.

In an optional implementation manner, scenes with different types of pen points can be connected to the same pen holder, after the electronic device is in communication connection with a touch pen, a pen point type acquisition request can be sent to the touch pen, after the touch pen receives the pen point type acquisition request sent by the electronic device, the pen point type identifier can be fed back to the electronic device, after the electronic device receives the pen point type identifier, relevant parameters such as a corresponding first threshold value and a preset use threshold value can be acquired according to a preset mapping relation, so that the electronic device can generate accurate pen point service life prompting information, a user is prevented from being reminded by mistake, and use experience of the user is influenced. Of course, after the pen tip is replaced, the user may update the information of the pen tip (for example, the pen tip type, the first threshold corresponding to the pen tip, and the preset usage threshold) in the stylus information recorded by the electronic device by himself or herself, which is not limited herein.

Wherein, presetting the mapping relation comprises: the pen nib type identifiers respectively correspond to a first threshold value and a preset use threshold value. Optionally, the preset mapping relationship may be obtained through a stylus application program, and the preset mapping relationship in the stylus application program may be imported by an application program manager, or may be obtained through a cloud, and of course, a specific obtaining manner is not limited thereto.

In another optional implementation manner, multiple pen tip type identifiers may be stored in the electronic device, and if it is determined that the user has replaced the pen tip, a pen tip type selection interface may be displayed, where the pen tip type selection interface may include multiple pen tip type identifiers, and at this time, the user may select the pen tip type identifier corresponding to the replaced pen tip through a touch manner such as clicking, sliding, dragging, long-pressing, and the like based on a touch screen of the electronic device, so that the electronic device may accurately acquire the type of the replaced pen tip. Of course, in some embodiments, after the user replaces the pen tip, the pen tip type identifier of the replaced pen tip may also be manually edited, for example, if it is determined that the user replaces the pen tip, the electronic device may display a pen tip type editing interface, and at the pen tip type editing interface, the user may manually edit the pen tip type identifier corresponding to the replaced pen tip, and optionally, during the specific editing, the user may edit the pen tip type identifier on the stylus pen, which is not limited herein.

In an alternative embodiment, if different types of pen tips are connected to the pen shaft differently, the stylus may determine the type of the connected pen tip by comparing the current connection mode of the pen tip to the pen shaft with the previous connection mode, and determining whether the type of the pen tip has changed. Optionally, if the connection manner of the soft plastic type pen tip and the pen holder is a threaded connection manner, and the connection manner of the conductive soft rubber type pen tip and the pen holder is a snap-fit connection manner, the pen holder may detect the connection manner with the pen tip through its internal related sensors (e.g., optical sensor, pressure sensor, etc.), and then determine the pen tip type identifier corresponding to the pen tip, and the determined pen tip type identifier may be sent to the electronic device. It can be understood that if the pen holder detects that the connection mode (threaded connection) of the current pen tip is different from the connection mode (snap-fit connection) of the previous pen tip, it can be considered that the type of the pen tip currently replaced by the user is different from the type of the previous pen tip. Currently, the specific identification method of the pen tip type is not limited to the above description.

Further, it can be understood that, if the user replaces the pen tip with reference to the pen tip life prompting information, in this case, the pen tip in the stylus pen is a new pen tip, in order to facilitate the electronic device to determine and record that the pen tip is replaced with the stylus pen, so as to accurately record the accumulated use duration of the pen tip of the new pen tip, optionally, the stylus pen may send a pen tip replacement message to the electronic device, optionally, the pen tip replacement message may include a pen tip type identifier, a pen tip replacement time, and the like, and for the electronic device, the electronic device may determine and record that the pen tip is replaced after receiving the pen tip replacement message. In some embodiments, if the stylus may further include a button, the button may be electrically connected to the main circuit board (e.g., via a wire or a flexible circuit board), and optionally, the button may be configured to transmit a tip replacement message to the electronic device in response to a control operation (e.g., a pressing operation, a dialing operation) by the user.

Fig. 10 is a schematic diagram illustrating a tip replacement prompt of a stylus according to an embodiment of the present disclosure. In this embodiment, based on the fact that the more serious the nib wear of the stylus pen, the larger the semaphore of the electrode signal generated by the stylus nib electrode will be, the electronic device may detect the semaphore of the electrode signal generated by the stylus nib electrode, and determine whether the stylus pen has replaced the nib according to the detected semaphore of the electrode signal and the semaphore of the electrode signal detected last time.

If the signal quantity of the detected electrode signal is smaller than the signal quantity of the electrode signal detected last time, the abrasion degree of the pen point is changed, and the user is determined to replace the pen point.

In consideration of the fact that in an actual application scenario, the signal quantity of the electrode signal detected by the electronic device is influenced by the writing mode, the writing environment, and the like, and therefore, there may be a case where the user does not change the pen tip, but the signal quantity of the detected electrode signal is smaller than the signal quantity of the electrode signal detected at the previous time. Alternatively, the preset condition may be a preset difference, which may be set according to human experience, and is not limited herein.

As shown in fig. 10, a replacement prompt window 205 may be displayed, the replacement prompt window 205 may include a determination control 2051, and in fig. 10, for example, the replacement prompt window 205 is configured to enable a user to further confirm whether the pen tip BJA _001 in the stylus BG _001 has been replaced by the BJB _004, at this time, if the pen tip is replaced, the user may act on the determination control 2051 by a touch manner such as clicking, long-pressing, sliding, and re-pressing based on the touch screen of the electronic device to generate a determination operation for the determination control 2051, and in response to the determination operation, the electronic device 200 may determine and record the replacement pen tip.

In addition, it can be understood that, after the electronic device determines that the pen tip is replaced, that is, after the electronic device determines that a new pen tip is replaced, the accumulated use time of the pen tip of the new pen tip can be recorded again.

If the replaced new pen point is the same as the previous pen point in type, for example, the new pen point is a conductive soft rubber pen point, the accumulated service life of the pen point corresponding to the previous pen point can be cleared to zero to realize updating; or, if each pen tip has a corresponding pen tip identifier and each pen tip type has a corresponding pen tip type identifier, optionally, after the new pen tip is replaced, the electronic device may record the accumulated use duration of the pen tip corresponding to the new pen tip according to the pen tip identifier of the new pen tip and the pen tip type identifier, and the application does not limit a specific recording manner herein.

Fig. 11 is a schematic diagram illustrating pen tip replacement details of a stylus according to an embodiment of the present disclosure. Further, after the electronic device 200 determines to replace the pen tip, in order to facilitate the user to know information of the new pen tip, the electronic device may display replacement prompt information after determining and recording to replace the pen tip, which may include, but is not limited to: identification of the new pen tip, identification of the type of the new pen tip, attribute parameters of the new pen tip, and the like. Wherein the attribute parameters of the new pen tip may include: the brand information, the expected usable time information, the replacement time information, the use instruction information, and the like are not limited herein, and can be flexibly set according to the actual application scenario. Optionally, the replacement prompt information may be displayed in a form of a prompt window, as shown in fig. 11, a pen tip replacement detail window 206 may be displayed, or a stylus application program is skipped to, and the pen tip replacement detail window is displayed by the stylus application program, where a specific display mode may refer to the display mode of the pen tip life prompt information, and this application is not described herein again.

As can be seen from fig. 11, the nib replacement details window 206 may display preset text content, for example, prompt the user to replace the nib of the stylus BG _001 by 20 minutes at 10/1/10/2021, where the replaced nib is BJB _004, the replaced nib is expected to be continuously used for 100 hours, and it should be noted that, according to an actual application scenario, the nib replacement details window 206 may further display related information of the nib before replacement, which may include but is not limited to: the nib identifier before replacement, the accumulated use time of the nib before replacement, and the like.

Based on the foregoing description, when the stylus is used as the execution body, the pressure of the writing end of the pen tip 10 can be detected by the pressure sensor during writing by the stylus, so that the coding time of the pen tip can be obtained according to the duration of the pressure.

Optionally, according to each coding time of the pen tip, the stylus may calculate and record the accumulated use duration of the pen tip, and send the recorded accumulated use duration of the pen tip to the electronic device 200; or, the stylus may send the obtained coding time to the electronic device 200 according to a first preset period (e.g., 0.5 hour, 2 hours, etc.), and optionally, the electronic device 200 may correspondingly store the coding time according to the identifier of the pen tip in the stylus after receiving the pen tip coding time of the stylus in each first preset period, and perform summation calculation to obtain the accumulated use time of the pen tip of the stylus.

It should be noted that the connection mode between the stylus and the electronic device may be a direct communication connection, such as the aforementioned WI-FI hotspot network, WI-FI peer-to-peer (P2P) network, bluetooth network, zigbee network, or Near Field Communication (NFC) network, which is a short-range communication network. In addition, the touch pen can be in communication connection with external devices such as a pen holder, a pen container or a wireless keyboard, and the external devices are in communication connection with the electronic device to help the touch pen to forward information.

Accordingly, when the stylus transmits the recorded cumulative service time of the pen tip to the electronic device, the transmission may be direct transmission or indirect transmission, which is not limited herein, and for the description of this portion, reference may be made to the related portions described above, which are not described herein again.

In addition, it should be further noted that, in the embodiment of the present application, a relationship between the first preset period, the second preset period, and the third preset period is not limited, and the setting may be flexible according to an actual application scenario.

In some embodiments, considering that the storage space of the storage device in the stylus is limited, optionally, the stylus may clear the stored pen tip coding time and the accumulated pen tip usage time when detecting to replace the pen tip. In some application scenes, in order to avoid zero clearing misoperation, the identifier of the previous nib and the identifier of the new nib can be acquired, and whether the stored nib coding time and the accumulated nib use duration are cleared is determined by comparing whether the identifiers of the previous nib and the new nib are the same or not. If the two identifications are different, the nib coding time and the nib accumulated use duration corresponding to the previous nib which can be stored are reset, so that the corresponding nib coding time and the nib accumulated use duration of the new nib can be stored and reset, the loss of related data is avoided, otherwise, the clearing operation is not performed, and the misoperation is avoided.

In an optional embodiment, if the stylus detects a pen tip replacement operation, or receives a pen tip update message sent by the terminal, it determines that the pen tip has been replaced. For the content of this part, reference is made to the related description above, and further description is omitted here.

Fig. 12 is a schematic diagram of a hardware structure of a stylus according to an embodiment of the present disclosure. Referring to FIG. 12, stylus 100 may have a processor 110, and processor 110 may include storage and processing circuitry for supporting the operation of stylus 100. The storage and processing circuitry may include storage devices such as non-volatile memory (e.g., flash memory or other electrically programmable read-only memory configured as a solid state drive), volatile memory (e.g., static or dynamic random access memory), and so forth. Processing circuitry in processor 110 may be used to control the operation of stylus 100. The processing circuitry may be based on one or more microprocessors, microcontrollers, digital signal processors, baseband processors, power management units, audio chips, application specific integrated circuits, and the like.

One or more sensors can be included in stylus 100. For example, pressure sensors 120, inertial sensors 130, etc., where inertial sensors 130 may include a three-axis accelerometer and a three-axis gyroscope, and/or other components for measuring motion of stylus 100, for example, a three-axis magnetometer may be included in the sensors in a nine-axis inertial sensor configuration. The sensors may also include additional sensors such as temperature sensors, ambient light sensors, light-based proximity sensors, contact sensors, magnetic sensors, pressure sensors, and/or other sensors.

A status indicator 140, such as a light emitting diode, and a button 150 may be included in stylus 100, and status indicator 140 may be used to indicate to a user the status of stylus 100, which may include, but is not limited to: a connection state with the electronic device (e.g., connected, disconnected, sleep state, etc.), a power state. Buttons 150 may include mechanical and non-mechanical buttons, and buttons 150 may be used to collect button press information from a user.

In this embodiment, the stylus 100 may include one or more electrodes, one of which may be located at the writing end of the stylus 100, as shown above, the electrode TX may be located in the pen tip, and the electrode RX may be located in the pen barrel, as described above.

Sensing circuitry 170 may also be included in stylus 100. Sensing circuitry 170 can sense capacitive coupling between electrodes 160 and drive lines of a capacitive touch sensor panel interacting with stylus 100. The sensing circuit 170 can include an amplifier to receive capacitance readings from the capacitive touch sensor panel, a clock to generate a demodulation signal, a phase shifter to generate a phase shifted demodulation signal, a mixer to demodulate the capacitance readings using an in-phase demodulation frequency component, and a mixer to demodulate the capacitance readings using a quadrature demodulation frequency component, among others. The results of the mixer demodulation can be used to determine an amplitude proportional to the capacitance so that stylus 100 can sense contact with the capacitive touch sensor panel.

It is understood that stylus 100 may include a microphone, speaker, audio generator, vibrator, camera, data port, display screen, and other devices, as desired. A user can control the operation of stylus 100 and electronic device 200 interacting with stylus 100 by providing commands with these devices, as well as receive status information and other outputs.

Processor 110 may be used to run software on stylus 100 that controls the operation of stylus 100. During operation of stylus 100, software running on processor 110 may process sensor inputs, button inputs, and inputs from other devices to monitor movement of stylus 100 and other user inputs. Software running on the processor 110 may detect the user command and may communicate with the electronic device 200.

To support wireless communication of stylus 100 with electronic device 200, stylus 100 may include a wireless module. Fig. 12 illustrates an example in which the bluetooth module 180 is a wireless module. The wireless module can also be a WI-FI hotspot module, a WI-FI point-to-point module and the like. Bluetooth module 180 may include a radio frequency transceiver, such as a transceiver. Bluetooth module 180 may also include one or more antennas. The transceiver may transmit and/or receive wireless signals, which may be bluetooth signals, wireless local area network signals, long range signals such as cellular telephone signals, near field communication signals, or other wireless signals, based on the type of wireless module, using the antenna.

Stylus 100 may further include a charging module 190, and charging module 190 may support charging of stylus 100 to provide power to stylus 100.

Fig. 13 is a schematic hardware structure diagram of an electronic device according to an embodiment of the present application. Referring to fig. 13, the electronic device 200 may include a plurality of subsystems that cooperate to perform, coordinate, or monitor one or more operations or functions of the electronic device 200. Electronic device 200 includes processor 210, input surface 220, coordination engine 230, power subsystem 240, power connector 250, wireless interface 260, and display 270.

For example, coordination engine 230 may be used to communicate with and/or process data with other subsystems of electronic device 200; communicating and/or transacting data with stylus 100; measuring and/or obtaining the output of one or more analog or digital sensors (such as touch sensors); measuring and/or obtaining an output of 1 or more sensor nodes of an array of sensor nodes (such as an array of capacitive sensing nodes); receiving and locating tip and ring signals from stylus 100; the stylus pen 100 and the like are positioned based on the positions of the tip signal crossing region and the ring signal crossing region.

Coordination engine 230 of electronic device 200 includes or is otherwise communicatively coupled to a sensor layer located below or integrated with input surface 220. Coordination engine 230 locates stylus 100 on input surface 220 using the sensor layer and uses the techniques herein to estimate the angular position of stylus 100 relative to the plane of input surface 220. In one embodiment, the input surface 220 may be referred to as a touch screen 201.

For example, the sensor layer of coordination engine 230 of electronic device 200 is a grid of capacitive sensing nodes arranged as columns and rows. More specifically, the array of column traces is disposed perpendicular to the array of row traces. The sensor layer may be separate from other layers of the electronic device, or the sensor layer may be disposed directly on another layer, such as, but not limited to: display stack layers, force sensor layers, digitizer layers, polarizer layers, battery layers, structural or decorative outer shell layers, and the like.

The sensor layer can operate in multiple modes. If operating in mutual capacitance mode, the column and row traces form a single capacitive sensing node at each overlap point (e.g., a "vertical" mutual capacitance). If operating in self-capacitance mode, the column and row traces form two (vertically aligned) capacitive sensing nodes at each overlap point. In another embodiment, adjacent column traces and/or adjacent row traces may each form a single capacitive sensing node (e.g., a "horizontal" mutual capacitance) if operating in a mutual capacitance mode. As above, the sensor layer may detect the presence of the tip 10 of the stylus 100 and/or the touch of the user's finger by monitoring changes in capacitance (e.g., mutual or self capacitance) present at each capacitive sensing node. In many cases, coordination engine 230 may be configured to detect tip and ring signals received from stylus 100 through the sensor layer via capacitive coupling.

Wherein the tip signal and/or the ring signal can include specific information and/or data that can be configured to cause electronic device 200 to recognize stylus 100. Such information is generally referred to herein as "stylus identity" information. This information and/or data may be received by the sensor layer and interpreted, decoded, and/or demodulated by the coordination engine 230.

The processor 210 may use the stylus identity information to receive input from more than one stylus at the same time. In particular, the coordination engine 230 may be configured to transmit the position and/or angular position of each of the number of styli detected by the coordination engine 230 to the processor 210, in other cases the coordination engine 230 may also transmit information to the processor 210 regarding the relative positions and/or relative angular positions of the plurality of styli detected by the coordination engine 230. For example, the coordination engine 230 may notify the processor 210 that the detected first stylus is located a distance from the detected second stylus.

In other cases, the end signal and/or the ring signal may also include specific information and/or data for the electronic device 200 to identify a specific user. Such information is generally referred to herein as "user identity" information.

The coordination engine 230 can forward the user identity information (if detected and/or recoverable) to the processor 210, and if the user identity information cannot be recovered from the tip signal and/or the ring signal, the coordination engine 230 can optionally indicate to the processor 210 that the user identity information is not available. The processor 210 can utilize the user identity information (or the absence of such information) in any suitable manner, including but not limited to: accept or reject input from a particular user, allow or reject access to a particular function of the electronic device, and the like. The processor 210 may use the user identity information to receive input from more than one user at the same time.

In still other cases, the tip signal and/or the ring signal may include specific information and/or data that may be configured to cause the electronic device 200 to identify settings or preferences of the user or stylus 100. Such information is generally referred to herein as "stylus setting" information.
