[0038] Embodiments of the present disclosure are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present disclosure, and should not be construed as limiting the present disclosure.
[0039] The embodiment of the present disclosure takes the stylus control method being configured in a stylus control device as an example. The stylus control device can be applied to any electronic device, such as a touch screen or a stylus, so that the electronic device can execute the stylus control method, which is not limited here.
[0040] The following describes the stylus pen control method, device, electronic device, and storage medium according to the embodiments of the present disclosure with reference to the accompanying drawings.
[0041] Figure 1 A schematic flow chart of a stylus pen control method provided in an embodiment of the present disclosure.
[0042] like Figure 1 As shown, the stylus pen control method is executed by the stylus pen and may include the following steps:
[0043] Step 101: receiving a coding parameter adjustment request sent by a first electronic device, wherein the coding parameter adjustment request includes a current first refresh rate and a first index of a first touch screen of the first electronic device.
[0044] The electronic device may be a tablet computer, a computer, a mobile phone, a television, or any other device with a touch screen, which is not limited here. The first electronic device may be an electronic device that currently sends a coding parameter adjustment request to the stylus.
[0045] It should be noted that, when a communication connection is established between the first electronic device and the stylus, the stylus can receive the coding parameter adjustment request sent by the first electronic device. As a possible implementation method, before receiving the coding parameter adjustment request sent by the touch screen of the first electronic device, the stylus can establish a communication connection with multiple electronic devices (including the first electronic device). The stylus can receive the coding parameter adjustment request sent by each electronic device in real time.
[0046] Optionally, the multiple electronic devices can be different types of devices. For example, the stylus can establish communication with a mobile phone and a tablet computer at the same time, so that the stylus can touch the mobile phone or tablet computer. If the stylus was originally used on a mobile phone for a period of time and then moved to a tablet computer for touch control, the tablet computer can determine whether the conditions for sending a coding parameter adjustment request are met, that is, the coding parameter adjustment conditions are met. If the coding parameter adjustment conditions are met, the tablet computer can send a coding parameter adjustment request to the stylus so that the stylus updates the current coding parameters.
[0047] For example, if the coding parameter A is used when the stylus is used on a mobile phone, when the stylus is switched to a tablet computer, the tablet computer needs to adjust the coding parameter A currently used by the stylus, thereby updating it to the coding parameter that matches the tablet computer. Therefore, a coding parameter adjustment request can be sent to the stylus at this time. Since the stylus has established communication with the tablet computer, it can receive the coding parameter adjustment request, which is not limited here.
[0048] Alternatively, if the stylus is used on a mobile phone, the current screen refresh rate of the mobile phone touch screen is A1, and the stylus uses the mobile phone touch screen through the coding parameter U matching A1. If the mobile phone touch screen changes the screen refresh rate from A1 to A2, the coding parameters U and A2 are not matching at this time, so a coding parameter adjustment request can be sent to the stylus so that the stylus can adjust the coding parameter U to meet the screen refresh rate A2, which is not limited here.
[0049] As a possible implementation method, the stylus can establish a BLE (Bluetooth Low Energy) connection with the electronic device in advance. Among them, BLE adopts a master-slave architecture, with the stylus as the master device and each electronic device as the slave device, so as to support wireless communication between the stylus and multiple electronic devices, and enable the stylus to connect to multiple electronic devices at the same time. As a result, the stylus can receive a coding parameter adjustment request sent by any electronic device that is currently establishing a communication connection.
[0050] Among them, the touch screen can be a tablet touch screen, a computer touch screen, a folding screen, a TV touch screen, etc., which is not limited here.
[0051] It should be noted that the touch screen can be a capacitive touch screen, an electromagnetic touch screen or a pressure-sensitive touch screen, which is not limited here. Among them, the capacitive touch screen can detect the position and pressure of the touch and support stylus operation. The electromagnetic touch screen uses electromagnetic induction to detect the position and pressure of the stylus, so it can support stylus operation. The pressure-sensitive touch screen can implement different operations according to the change of touch pressure, so it can support stylus operation.
[0052] The coding parameters may be parameters used for communication and interaction between the touch screen and the stylus. During the communication process between the touch screen and the stylus, some parameters need to be defined to ensure accurate touch input and response, namely, coding parameters.
[0053] The coding parameters may be resolution parameters, pressure parameters, delay parameters, sensitivity parameters, etc., which are not limited here. The pressure parameters can be used to adjust the pressure response range and sensitivity of the pen tip. The sensitivity can adapt to the touch strength and finger / pen tip size of different users. The resolution parameter of the touch screen refers to the number of pixels per inch on the screen, while the resolution of the stylus refers to the precise position of the pen tip. Accurate touch input and delicate operation can be achieved through resolution matching.
[0054] It should be noted that the coding parameters corresponding to the same touch screen at different refresh rates may be different.
[0055] The coding parameter adjustment request may be used to adjust the coding parameters of the stylus pen, so that the stylus pen can be used in the touch screen.
[0056] Among them, the first refresh rate can be the current screen refresh rate of the touch screen, such as 60 Hz, which is not limited here.
[0057] The first index may be index information between the first refresh rate and the coding parameter associated with the first refresh rate. Through the first index, the stylus pen may determine the coding parameter associated with the first refresh rate.
[0058] Step 102: query a first preset coding parameter mapping table to obtain a first coding parameter associated with a first refresh rate and a first index.
[0059] The coding parameter mapping table may include coding parameters corresponding to different refresh rates and indexes.
[0060] The first preset coding parameter mapping table may be a coding parameter mapping table stored in the stylus pen.
[0061] The first coding parameter may be a coding parameter corresponding to the first refresh rate and the first index.
[0062] Specifically, after the stylus receives the coding parameter adjustment request, it can query the coding parameter mapping table to obtain the first coding parameter corresponding to the first refresh rate and the first index.
[0063] For example, if the first refresh rate is 90 Hz and the first index is ID1, the stylus can obtain the first coding parameter corresponding to the refresh rate of 90 Hz and ID1 from the coding parameter mapping table.
[0064] It should be noted that the first preset coding parameter mapping table may store coding parameters corresponding to each refresh rate and index corresponding to each electronic device.
[0065] For example, the first preset coding parameter mapping table may be as shown in the following table:
[0066] index Refresh rate Coding parameters ID1 60Hz E1 ID2 90Hz E2 ID3 100Hz E3 ID4 60Hz E4 ID5 70Hz E5 ID6 80Hz E6
[0067] As shown in the table above, when the refresh rate is the same but the index is different, the coding parameters are also different. If the first preset coding parameter mapping table contains indexes corresponding to multiple electronic devices, then when two or more electronic devices have the same refresh rate, different indexes need to be generated. Among them, ID1, ID2, and ID3 can be for tablets, and ID4, ID5, and ID6 can be for folding screens. Different refresh rates of tablets correspond to different coding parameters E1, E2, and E3, and different refresh rates of folding screens correspond to different coding parameters E4, E5, and E6. When the tablet and folding screen both have a 60Hz refresh rate, the corresponding indexes are different, ID2 and ID4, respectively, and the corresponding coding parameters are also different, E1 and E4, respectively.
[0068] Step 103: output a coding signal to the first touch screen based on the first coding parameter.
[0069] It should be noted that the touch screen in the embodiment of the present disclosure may be a TPIC touch screen, which uses a TPIC (Touch Panel Integrated Circuit) chip to detect and process touch input. A TPIC chip is an integrated circuit with special functions and algorithms for processing touch input signals on a touch screen.
[0070] The communication and interaction between the TPIC touch screen and the stylus is achieved through coding parameters. Coding parameters refer to the parameters used when the touch screen and the stylus communicate. When the stylus moves or clicks on the TPIC touch screen, the stylus will generate corresponding coding signals based on the current position and operation action, and send them to the TPIC touch screen.
[0071] The coding signal is a specific electrical signal that contains the coordinate information of the position of the touch pen tip and other possible parameters, such as pressure sensitivity. The TPIC touch screen will receive and parse the coding signal, determine the coordinates of the touch point based on the position information in the signal, and convert it into corresponding operations or instructions. By setting and optimizing the coding parameters, the accuracy and response speed between the TPIC touch screen and the stylus can be improved, thereby enhancing the user's touch experience. The first touch screen can receive and parse the coding signal, determine the coordinates of the touch point based on the position information in the coding signal, and convert it into corresponding operations or instructions based on the first coding parameters. As a result, the user can perform precise operations on the first touch screen with the stylus, such as writing, drawing, clicking, etc.
[0072] As an optional implementation method, before outputting a coding signal to the touch screen based on the first coding parameter, the coding parameter of the stylus pen can be switched from the second coding parameter to the first coding parameter, wherein the second coding parameter is a coding parameter associated with the second touch screen of the second electronic device connected to the stylus pen.
[0073] The second coding parameter may be a coding parameter used by the stylus pen in conjunction with the second electronic device before receiving the coding parameter adjustment request.
[0074] The second touch screen may be a touch screen of a second electronic device, that is, a touch screen used by the stylus before switching to the first touch screen. The second electronic device may be an electronic device used by the stylus for touch control before receiving the coding parameter adjustment request.
[0075] For example, if the stylus was originally used for touch control on a mobile phone and then moved to a tablet for touch control, then the mobile phone can be the second electronic device, the touch screen of the mobile phone is the second touch screen, and the coding parameters used in conjunction with the stylus and the mobile phone are the second coding parameters. The stylus can switch the second coding parameters to the first coding parameters used in conjunction with the tablet, and the tablet is the first electronic device.
[0076] Alternatively, if the stylus pen does not switch the electronic device but the electronic device adjusts the refresh rate, the stylus pen can adjust the coding parameter to the coding parameter corresponding to the refresh rate adjusted by the electronic device, that is, the first coding parameter.
[0077] As an example, if the stylus originally used with the refresh rate K1 of the first electronic device has a coding parameter P1, and the first electronic device adjusts the refresh rate from K1 to K2, the stylus needs to adjust the coding parameter P1 to the first coding parameter corresponding to the refresh rate K2.
[0078] In the disclosed embodiment, the stylus first receives a coding parameter adjustment request sent by the first electronic device, wherein the coding parameter adjustment request includes the current first refresh rate and first index of the first touch screen of the first electronic device, and then queries a first preset coding parameter mapping table to obtain the first coding parameter associated with the first refresh rate and the first index, and then outputs a coding signal to the first touch screen based on the first coding parameter. Thus, the coding parameter of the coding signal currently output by the stylus can be adjusted in time, so that the adjusted first coding parameter can meet the needs of the touch screen, and the touch screen can be switched.
[0079] Figure 2 A schematic flow chart of a stylus pen control method provided in an embodiment of the present disclosure.
[0080] like Figure 2 As shown, the stylus pen control method is executed by the stylus pen and may include the following steps:
[0081] Step 201: receiving an index generation request sent by a first electronic device, wherein the index generation request includes a first refresh rate and a first coding parameter.
[0082] The index generation request is used to request the stylus to generate index information between the first refresh rate and the first coding parameter.
[0083] As an example, the first electronic device may send an index generation request to the stylus when establishing a communication connection with the stylus for the first time, so as to send the current first refresh rate and the first coding parameter associated with the first refresh rate to the stylus, so that the stylus can receive the index generation request sent by the first electronic device.
[0084] It should be noted that during the process of establishing a communication connection between the first electronic device and the stylus for the first time, when the stylus is touching the first electronic device, the first electronic device changes the refresh rate, then the first electronic device can send an index generation request to the stylus, thereby sending the changed refresh rate and the coding parameters corresponding to the changed refresh rate to the stylus, so that the stylus can receive the index generation request sent by the first electronic device.
[0085] Step 202: Generate a first index associated with a first refresh rate and a first coding parameter, wherein the first index is different from a second index in a coding parameter mapping table.
[0086] The second index may be an index that associates the remaining refresh rates except the first refresh rate with the corresponding coding parameters in the coding parameter mapping table.
[0087] Specifically, after receiving the index generation request, the stylus pen can generate a first index associated with the first refresh rate and the first coding parameter. For example, if the first refresh rate is 80 Hz and the first coding parameter is D, the index information ID2 associated with 80 Hz and D can be generated. Therefore, after the stylus pen receives a coding parameter adjustment request, if the coding parameter adjustment request includes the first refresh rate 80 Hz and the first index ID2, the stylus pen can determine the first coding parameter D associated with the first refresh rate 80 Hz according to the first index ID2.
[0088] Optionally, after generating the first index, the stylus pen may send the first index, the first refresh rate and the first coding parameter to the touch screen, whereby the touch screen may store the first index, the first refresh rate and the first coding parameter in an associated manner.
[0089] Step 203: associate the first index, the first refresh rate and the first coding parameter and store them in a first preset coding parameter mapping table.
[0090] Specifically, the first index, the first refresh rate and the first coding parameter can be associated and stored in a first preset coding parameter mapping table, so that after the stylus receives a coding parameter adjustment request, if the coding parameter adjustment request includes the first refresh rate and the first index, the stylus can determine the first coding parameter associated with the first refresh rate based on the first index.
[0091] Step 204: receiving a coding parameter adjustment request sent by the first electronic device, wherein the coding parameter adjustment request includes a current first refresh rate and a first index of the first touch screen of the first electronic device.
[0092] Step 205 , querying a first preset coding parameter mapping table to obtain a first coding parameter associated with a first refresh rate and a first index.
[0093] Step 206: output a coding signal to the first touch screen based on the first coding parameter.
[0094] It should be noted that the specific implementation of steps 204-206 can refer to the above embodiment and will not be described in detail here.
[0095] In the disclosed embodiment, the stylus first receives an index generation request sent by a first electronic device, wherein the index generation request includes a first refresh rate and a first coding parameter, then generates a first index associated with the first refresh rate and the first coding parameter, wherein the first index is different from a second index in a coding parameter mapping table, then stores the first index, the first refresh rate and the first coding parameter in association with each other in a first preset coding parameter mapping table, receives a coding parameter adjustment request sent by the first electronic device, wherein the coding parameter adjustment request includes the current first refresh rate and the first index of the first touch screen of the first electronic device, then queries the first preset coding parameter mapping table to obtain the first coding parameter associated with the first refresh rate and the first index, and then outputs a coding signal to the first touch screen based on the first coding parameter. Thus, the association relationship between the first index, the first refresh rate and the first coding parameter can be established in advance and stored, so that the associated first coding parameter can be directly obtained according to the first refresh rate and the first index.
[0096] Figure 3 A schematic flow chart of a stylus pen control method provided in an embodiment of the present disclosure.
[0097] like Figure 3 As shown, the stylus pen control method is executed by an electronic device and may include the following steps:
[0098] Step 301, when the coding parameter adjustment condition is met, determine the current first refresh rate of the touch screen.
[0099] The coding parameter adjustment condition is used to control the stylus pen to adjust the current coding parameters.
[0100] As a possible implementation method, the electronic device may determine that the coding parameter adjustment condition is met when a refresh rate adjustment instruction is received and the stylus pen is in contact with any position of the touch screen.
[0101] The refresh rate adjustment instruction is used to update the refresh rate of the touch screen, such as adjusting 60 Hz to 75 Hz, which is not limited here.
[0102] The first refresh rate may be the current refresh rate of the touch screen, or may be the refresh rate to be adjusted contained in the refresh rate. For example, if the refresh rate adjustment instruction is to adjust 60 Hz to 75 Hz, the current first refresh rate of the touch screen may be the adjusted refresh rate, i.e., 75 Hz, which is not limited here.
[0103] For example, if the current refresh rate of the touch screen is 60Hz, and the stylus is clicking on position A on the touch screen, if the touch screen receives a refresh rate adjustment instruction and needs to adjust the refresh rate from 60Hz to 75Hz, then the coding parameter adjustment conditions are currently met.
[0104] It should be noted that if the stylus pen is not currently touching the touch screen, the stylus pen may be touching another screen, so when the refresh rate adjustment instruction is received, the coding parameter adjustment condition is not met.
[0105] As another possible implementation method, the electronic device detects that the stylus pen is currently in contact with any position of the touch screen, and no coding signal output by the stylus pen is received within a preset period of time before the current moment.
[0106] It should be noted that if the stylus starts a touch operation on the touch screen, for example, if the stylus moves from touch screen A to touch screen B, and no coding signal output by the stylus is received within a preset period of time before touch screen B is touched, it can be considered that the conditions for adjusting the coding parameters are met.
[0107] Step 302: query a second preset coding parameter mapping table to obtain a first index and a first coding parameter associated with a first refresh rate.
[0108] The second preset coding parameter mapping table may be a coding parameter mapping table stored in the touch screen.
[0109] It should be noted that the second preset coding parameter mapping table may include indexes and coding parameters corresponding to various refresh rates. Specifically, the associated first index and first coding parameter may be obtained according to the first refresh rate.
[0110] For example, the second preset coding parameter mapping table may be as shown in the following table:
[0111] Refresh rate index Coding parameters 60Hz ID1 E1 90Hz ID2 E2 100Hz ID3 E3 120Hz ID4 E4
[0112] It should be noted that each refresh rate has a corresponding index and coding parameter. The above example is only an illustrative description and is not intended to limit the present disclosure.
[0113] Step 303: Send a coding parameter adjustment request to the stylus, wherein the coding parameter adjustment request includes a first refresh rate and a first index.
[0114] Specifically, the electronic device may send a coding parameter adjustment request to the stylus pen, so that the stylus pen may adjust its own first coding parameter according to the coding parameter adjustment request, and output a corresponding coding signal to the touch screen based on the first coding parameter.
[0115] Step 304: receiving a coding signal output by the stylus based on the first coding parameter.
[0116] It should be noted that when the stylus moves or clicks on the touch screen, the touch position information can be transmitted to the touch screen via a coding signal.
[0117] Specifically, the coding signal is a specific electrical signal. When the stylus pen interacts with the touch screen, the stylus pen will generate a corresponding coding signal based on the current position and operation action, as well as the coding parameters, and send it to the touch screen.
[0118] Therefore, the electronic device can receive and analyze the coding signal based on the touch screen, determine the coordinates of the touch point based on the position information in the coding signal, and convert it into a corresponding operation or instruction based on the first coding parameter. As a result, the user can use the stylus pen to perform precise operations on the touch screen, such as writing, drawing, clicking, etc.
[0119] Specifically, after the touch screen receives the coding signal, the electronic device can parse the coding signal based on the first coding parameter, display the corresponding display result on the touch screen according to the analysis result, and perform the corresponding operation according to the analysis result.
[0120] When the condition for adjusting the coding parameters is met, the electronic device determines the current first refresh rate of the touch screen, then queries the second preset coding parameter mapping table to obtain the first index and the first coding parameter associated with the first refresh rate, and then sends a coding parameter adjustment request to the stylus, wherein the coding parameter adjustment request includes the first refresh rate and the first index, and then can receive the coding signal output by the stylus based on the first coding parameter. Thus, when the condition for adjusting the coding parameters is met, the coding parameter adjustment request can be sent to the stylus, so that the stylus adjusts the coding parameters to meet the needs of the touch screen, and receives the coding signal based on the corresponding first coding parameter.
[0121] Figure 4 A schematic flow chart of a stylus pen control method provided in an embodiment of the present disclosure.
[0122] like Figure 4 As shown, the stylus pen control method is executed by an electronic device and may include the following steps:
[0123] Step 401, when the coding parameter adjustment condition is met, determine the current first refresh rate of the touch screen.
[0124] It should be noted that the specific implementation of step 401 can refer to the above embodiment and will not be described in detail here.
[0125] Step 402: Send an index generation request to the stylus, wherein the index generation request includes a first refresh rate and a first coding parameter.
[0126] The index generation request is used to request the stylus to generate index information between the first refresh rate and the first coding parameter.
[0127] As an example, the first electronic device may send an index generation request to the stylus when establishing a communication connection with the stylus for the first time, so as to send the current first refresh rate and the first coding parameter associated with the first refresh rate to the stylus, so that the stylus can receive the index generation request sent by the first electronic device.
[0128] It should be noted that during the process of establishing a communication connection between the first electronic device and the stylus for the first time, when the stylus is touching the first electronic device, the first electronic device changes the refresh rate, then the first electronic device can send an index generation request to the stylus, so that the changed refresh rate and the coding parameters corresponding to the changed refresh rate are sent to the stylus, so that the stylus can receive the index generation request sent by the first electronic device.
[0129] Step 403: Receive the first index returned by the stylus.
[0130] Step 404: associate the first index, the first refresh rate, and the first coding parameter and store them in a second preset coding parameter mapping table.
[0131] Specifically, after receiving the first index, the electronic device can store the first index, the first refresh rate and the first coding parameter in association, so that the electronic device can then obtain the first index and the first coding parameter associated with the first refresh rate according to the second preset coding parameter mapping table.
[0132] As a possible implementation method, when the touch screen supports multiple refresh rates, an index generation request can be sent to the stylus based on the second refresh rate and the second coding parameter associated with the second refresh rate, and then the second index returned by the stylus can be received. Then, the second index, the second refresh rate and the second coding parameter can be associated and stored in a second preset coding parameter mapping table.
[0133] The second refresh rate is a refresh rate among multiple refresh rates except the first refresh rate.
[0134] The second index may be index information between the second refresh rate and the coding parameter associated with the second refresh rate. Through the second index, the stylus pen may determine the coding parameter associated with the second refresh rate.
[0135] Figure 5 A schematic diagram of interaction between a stylus pen and an electronic device is shown.
[0136] like Figure 5 As shown, TPIC is a touch screen, and the stylus (stylus) can be connected to the tablet Bluetooth via BLE. The electronic device sends multiple index generation requests to the stylus via the tablet Bluetooth, which are index generation requests corresponding to 60Hz resolution, 90Hz resolution, 120Hz resolution, and 144Hz resolution, respectively, and obtains the corresponding 4 indexes, namely ID1, ID2, ID3 and ID4. After generating the index, the stylus associates and stores the 60Hz resolution, 90Hz resolution, 120Hz resolution, 144Hz resolution and the corresponding indexes ID1, ID2, ID3 and ID4, respectively, and the corresponding coding parameters.
[0137] Step 405 , querying a second preset coding parameter mapping table to obtain a first index and a first coding parameter associated with the first refresh rate.
[0138] Step 406: Send a coding parameter adjustment request to the stylus, wherein the coding parameter adjustment request includes the first refresh rate and the first index.
[0139] Step 407: receiving a coding signal output by the stylus pen based on the first coding parameter.
[0140] It should be noted that the specific implementation of steps 405, 406, and 407 can refer to the above embodiment and will not be described in detail here.
[0141] The electronic device first determines the current first refresh rate of the touch screen when the condition for adjusting the coding parameters is met, and then sends an index generation request to the stylus, wherein the index generation request includes the first refresh rate and the first coding parameter, and then receives the first index returned by the stylus, and then stores the first index, the first refresh rate and the first coding parameter in association with each other in the second preset coding parameter mapping table, and then queries the second preset coding parameter mapping table to obtain the first index and the first coding parameter associated with the first refresh rate, and then sends a coding parameter adjustment request to the stylus, wherein the coding parameter adjustment request includes the first refresh rate and the first index, and then can receive the coding signal output by the stylus based on the first coding parameter. Thus, the first index, the first refresh rate and the first coding parameter can be stored in association with each other in the second preset coding parameter mapping table in a timely manner, and the coding parameter adjustment request can be sent to the stylus when the condition for adjusting the coding parameters is met, so that the stylus adjusts the coding parameters to meet the needs of the touch screen, and receives the coding signal based on the corresponding first coding parameter.

[0154] Optionally, the generating unit is further used for:

[0156] The stylus first receives a coding parameter adjustment request sent by the first electronic device, wherein the coding parameter adjustment request includes the current first refresh rate and first index of the first touch screen of the first electronic device, and then queries a first preset coding parameter mapping table to obtain the first coding parameter associated with the first refresh rate and the first index, and then outputs a coding signal to the first touch screen based on the first coding parameter. Thus, the coding parameter of the coding signal currently output by the stylus can be adjusted in time, so that the adjusted first coding parameter can meet the needs of the touch screen, and the touch screen can be switched.

[0172] receiving a second index returned by the stylus;
[0173] The second index, the second refresh rate and the second coding parameter are associated and stored in the second preset coding parameter mapping table.
[0174] When the condition for adjusting the coding parameters is met, the electronic device determines the current first refresh rate of the touch screen, then queries the second preset coding parameter mapping table to obtain the first index and the first coding parameter associated with the first refresh rate, and then sends a coding parameter adjustment request to the stylus, wherein the coding parameter adjustment request includes the first refresh rate and the first index, and then can receive the coding signal output by the stylus based on the first coding parameter.
