[0023] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0024] Before describing the technical solution of the embodiment of the present application, the touch control system of the embodiment of the present application is first described in conjunction with the accompanying drawings. Figure 1 , is a schematic diagram of a touch control system provided in an embodiment of the present application. The touch control system 100 may include an electronic device 110 and a stylus 120. It should be understood that the electronic device 110 includes a touch display screen (not shown in the figure), which may also be referred to as a touch screen.

[0025] The stylus pen 120 may be, for example, an active stylus pen. The stylus pen 120 may include a circuit unit that can actively output a touch signal to the electronic device 110 for reception.

[0026] In some embodiments, when the stylus 120 moves onto the touch screen of the electronic device 110, the stylus 120 can send a touch signal to the electronic device 110 based on touch communication. The electronic device 110 can determine the position coordinate information of the stylus 120 on the touch screen through the receiving position of the touch signal. At the same time, the pressure signal and display line parameters (such as the color, shape, thickness and other parameter information of the line) of the stylus 120 on the touch screen can be sent to the electronic device 110 via Bluetooth connection. Then, according to the above-mentioned pressure signal, display line parameters and the position coordinate information of the stylus 120 on the touch screen, the touch operation of the electronic device 110 can be realized, and the touch operation is, for example, click, slide, write, draw and other operation functions.

[0027] In some embodiments, the touch communication may be wireless communication established based on a capacitive path formed when the stylus 120 contacts the electronic device 110 .

[0028] In some embodiments, the touch signal emitted by the stylus 120 may be, for example, a square wave signal, a sine wave signal, a triangle wave signal, etc.

[0029] It should be noted that the electronic device 110 in the embodiment of the present application may refer to an electronic device with a touch screen. The electronic device 110 may be a mobile phone, a tablet computer (Pad), a laptop computer, a PDA, a mobile internet device (MID), a wearable device, a virtual reality (VR) device, an augmented reality (AR) device, a smart large screen, etc., and the present application does not make any specific restrictions on this.

[0030] With the development of communication technology, the application of multi-electronic device collaboration scenarios is becoming more and more extensive. In the related art, a stylus switching method is proposed, which can enable the stylus to switch freely between multiple electronic devices. Figure 2A to Figure 2D , the switching method of the above-mentioned stylus pen is illustrated by examples.

[0031] Figure 2A to Figure 2D This is a schematic diagram of the principle of the switching method of the stylus provided in the related art, see Figure 2A , the stylus can be connected to the tablet and the mobile phone via Bluetooth. When the stylus is used to perform touch operations on the tablet, the tablet is the main device of the stylus, that is, the pressure-sensing signal of the stylus can be output to the tablet via Bluetooth, and the tablet can display the track on the screen of the tablet based on the received pressure-sensing signal and touch signal.

[0032] See also Figure 2B , the stylus can switch from the tablet to the mobile phone to write. Since the stylus does not sense the switch, the pressure signal of the stylus will still be sent to the main device before the switch (i.e. the tablet). For the tablet, it only receives the pressure signal but not the touch signal. Accordingly, the tablet can send event 1 to the stylus to indicate that the tablet receives the pressure signal but not the touch signal. It can be understood that when the stylus is writing on the mobile phone, the mobile phone can obtain the touch signal output by the stylus but fails to receive the pressure signal. Accordingly, the mobile phone sends event 2 to the stylus to indicate that the mobile phone receives the touch signal but fails to receive the pressure signal.

[0033] See also Figure 2C , the stylus can start the multicast mode based on the received event 1, event 2, or event 1 and event 2, that is, send pressure-sensitive signals to the electronic devices (including tablets and mobile phones) connected to it in a multicast manner. Correspondingly, since the mobile phone side receives the touch signal and the pressure-sensitive signal, the mobile phone determines that the ink output conditions are met, and the mobile phone can display the track on the screen based on the received pressure-sensitive signal and touch signal.

[0034] See also Figure 2D The stylus can determine the main device after switching (i.e., the mobile phone) based on different types of events received, such as event 1 for indicating that a pressure signal is received but a touch signal is not received, and / or event 2 for indicating that a touch signal is received but a pressure signal is not received, and send the subsequently generated pressure signal in a directed manner to the mobile phone side, thereby realizing the switching of the stylus from the tablet to the mobile phone.

[0035] It can be seen that the above-mentioned stylus switching method requires the electronic device to first determine the type of signal received and then report the corresponding event. Next, the stylus also needs to determine the event type reported by each electronic device and then start the multicast mode. Finally, the master device after switching is determined according to the event type to finally complete the switching. The switching process is relatively time-consuming, resulting in low switching efficiency and poor user experience.

[0036] In order to solve the above problems, the present application embodiment provides a switching method of a stylus, which is applied to a stylus, and the switching method includes: establishing a first wireless communication connection with a first electronic device; if the stylus switches from performing a touch operation on a second electronic device to performing a touch operation on a first electronic device, in response to receiving the device identification information of the first electronic device sent by the first electronic device through the second wireless communication connection, a first pressure-sensing signal is sent to the first electronic device through the first wireless communication connection, and the first pressure-sensing signal is a pressure-sensing signal generated when the stylus contacts the touch screen of the first electronic device; wherein the second wireless communication connection is a wireless communication connection established based on a capacitive path formed when the stylus contacts the first electronic device. It can be seen that this solution can actively send the device identification information of the current electronic device to the stylus through touch communication (i.e., the second wireless communication) by the electronic device, that is, when the stylus switches from the second electronic device to the first electronic device, it will actively notify the stylus of the electronic device (the first electronic device) where it is currently located, so that the stylus can quickly and accurately send the first pressure-sensing signal to the current electronic device (the first electronic device), thereby helping to improve the switching efficiency of the stylus between multiple electronic devices.

[0037] It should be noted that the switching method of the stylus in the embodiment of the present application can be applied to the scenario where the stylus is switched between multiple electronic devices. The multiple electronic devices may include a first electronic device and a second electronic device. The second electronic device may refer to the main device where the stylus is located before switching (that is, before switching, the stylus performs touch operations on the second electronic device). The first electronic device may refer to the main device after switching (that is, after switching, the stylus performs touch operations on the first electronic device). The first electronic device and the second electronic device may be any type of electronic device mentioned above. For example, the first electronic device may be a tablet computer, and the second electronic device may be a mobile phone. For another example, the first electronic device is a mobile phone, and the second electronic device is another mobile phone. This application does not impose specific restrictions on this. For the convenience of description, the following mainly takes the switching of the stylus from the second electronic device to the first electronic device as an example to illustrate the switching method of the stylus in the embodiment of the present application.

[0038] It should be noted that the stylus switching method in the embodiment of the present application is mainly illustrated from the perspective of the stylus and the first electronic device, and the stylus switching method corresponds to the stylus side and the first electronic device side. As an example, the stylus sends a pressure-sensing signal to the first electronic device, which can also be understood as the first electronic device receiving the pressure-sensing signal sent by the stylus.

[0039] Combined with the following Figure 3 The switching method of the stylus pen in the embodiment of the present application is described in detail. Figure 3 As shown, the stylus switching method 300 can be applied to a stylus and a first electronic device. The stylus can be, for example, Figure 1 The first electronic device may be, for example, Figure 1 The electronic device 110 in the embodiment of the present invention. The stylus switching method 300 may include steps S310 to S320.

[0040] In step S310, a first wireless communication connection is established with a first electronic device.

[0041] In some embodiments, the stylus can establish a first wireless communication connection with the first electronic device while establishing a first wireless communication connection with the second electronic device.

[0042] It is understandable that before switching, the stylus can perform touch operations on the second electronic device. For example, the stylus can send a pressure signal (i.e., a pressure signal generated when the stylus contacts the touch screen of the second electronic device) to the second electronic device through the first wireless connection. At the same time, the stylus can also send a touch signal to the second electronic device based on touch communication. Based on the pressure signal and the touch signal, a touch operation on the second electronic device can be implemented. The touch operation is, for example, click, slide, write, draw, and other operation functions.

[0043] It is understandable that when the stylus pen contacts the second electronic device, capacitive coupling may be performed, thereby generating a capacitive path, and the touch communication is formally based on the wireless communication established by the capacitive path.

[0044] In some embodiments, the signal waveform of the touch signal may be, for example, a square wave signal, a sine wave signal, a triangle wave signal, etc.

[0045] In some embodiments, the first wireless communication connection may be, for example, any one of the following wireless communications: Bluetooth connection, Wi-Fi connection, Zigbee connection, ultra-wideband connection, etc., and this application does not impose any specific limitation on this.

[0046] In step S320, if the stylus is switched from the second electronic device to the first electronic device for touch operation, in response to receiving the device identification information of the first electronic device sent by the first electronic device through the second wireless communication connection, a first pressure-sensing signal is sent to the first electronic device through the first wireless communication connection. The first pressure-sensing signal is a pressure-sensing signal generated when the stylus touches the touch screen of the first electronic device.

[0047] It should be noted that the second wireless communication connection is a wireless communication connection established based on a capacitive path formed when the stylus pen contacts the first electronic device. The second wireless communication may also be referred to as touch communication or pen-screen communication.

[0048] It can be understood that if the stylus is switched from the second electronic device to the first electronic device for touch operation, the first electronic device can send the device identification information of the first electronic device to the stylus through the second wireless communication connection; based on the device identification information, the stylus can send the first pressure signal to the first electronic device through the first wireless communication connection.

[0049] As an example, in response to the stylus switching from the second electronic device to the first electronic device for touch operation, the stylus will establish a second wireless communication connection with the first electronic device. Then, the first electronic device can send a synchronization signal to the stylus in the uplink synchronization signal time slot through the second wireless communication connection, wherein the synchronization signal can carry the device identification information of the first electronic device; after receiving the synchronization signal, the stylus can obtain the device identification information of the first electronic device from the synchronization signal; in response to receiving the device identification information of the first electronic device, the stylus can send a first pressure-sensitive signal to the first electronic device through the first wireless communication connection.

[0050] It can be seen that when the stylus switches from the second electronic device to the first electronic device, it will trigger the second wireless communication connection. At this time, the first electronic device will actively send the device identification information of the electronic device where the stylus is currently located (the first electronic device) to the stylus, so that the stylus can quickly and accurately send the first pressure-sensitive signal to the electronic device after the switch (the first electronic device), instead of continuing to send the first pressure-sensitive signal to the electronic device before the switch (the second electronic device), thereby helping to achieve rapid switching of touch operations from the second electronic device to the first electronic device, thereby improving the user experience.

[0051] In some embodiments, the first electronic device can send a synchronization signal to the stylus in the uplink synchronization signal time slot through the second wireless communication connection, and the synchronization signal can be used to align the clock information of the stylus with the clock information on the first electronic device side. Furthermore, the synchronization signal is also used to trigger the stylus to output a touch signal to the first electronic device side through the second wireless communication connection based on the aligned clock information.

[0052] It can be understood that in the embodiment of the present application, by carrying the device identification information of the first electronic device in the synchronization signal, the stylus can obtain the electronic device (the first electronic device) to which the stylus is located after switching before sending the touch signal to the first electronic device, so that the first pressure sensing signal can be quickly sent to the switched electronic device (the first electronic device), further improving the switching efficiency of the stylus.

[0053] In some embodiments, after the stylus establishes a first wireless communication connection with the first electronic device, the stylus can assign a corresponding device number to the first electronic device, that is, the stylus can send device identification information of the first electronic device (that is, the device identification information assigned by the stylus) to the first electronic device through the first wireless communication connection.

[0054] In some embodiments, the stylus can also establish a first wireless communication connection with a second electronic device, and then assign a corresponding device number to the second electronic device, that is, the stylus can send the device identification information of the second electronic device (that is, the device identification information assigned by the stylus) to the second electronic device through the first wireless communication connection.

[0055] The device identification information in the embodiment of the present application may refer to information that uniquely identifies the current electronic device. The device identification information may be, for example, the device ID number of the electronic device. As an example, the device ID number assigned by the stylus to the first electronic device may be 1, and the device ID number assigned by the stylus to the second electronic device may be 2.

[0056] In order to understand the above-mentioned stylus switching method, the following takes the stylus switching between multiple electronic devices as an example, where the multiple electronic devices include a first electronic device, a second electronic device, ..., an Nth electronic device, where N is a positive integer greater than 1. Figure 4A to Figure 4D The switching method of the touch pen is described in detail with examples.

[0057] See also Figure 4A , the stylus can be connected to multiple electronic devices through Bluetooth. Then, the stylus assigns different ID numbers to the multiple electronic devices and transmits the assigned numbers to the corresponding electronic devices via Bluetooth. For example, ID number 1 can be sent to the first electronic device, ID number 2 to the second electronic device, ..., ID number N to the Nth electronic device.

[0058] See also Figure 4B , the stylus performs touch operation on the first electronic device, and the first electronic device can send a synchronization signal to the stylus in the uplink synchronization signal time slot through the touch communication connection, wherein the synchronization signal carries ID number 1; after receiving ID number 1, the stylus can send a first pressure-sensing signal to the first electronic device through the Bluetooth communication connection, wherein the first pressure-sensing signal is a pressure-sensing signal generated when the stylus contacts the touch screen of the first electronic device. Accordingly, since the first electronic device receives the touch signal and the pressure-sensing signal, the touch operation on the first electronic device can be realized based on the pressure-sensing signal and the touch signal.

[0059] See also Figure 4C, the stylus switches from the first electronic device to the second electronic device for uplink touch operation, and the second electronic device can send a synchronization signal to the stylus in the uplink synchronization signal time slot through the touch communication connection, wherein the synchronization signal carries ID number 2; after receiving ID number 2, the stylus can send a second pressure-sensitive signal to the second electronic device through the Bluetooth communication connection, wherein the second pressure-sensitive signal is the pressure-sensitive signal generated when the stylus contacts the touch screen of the second electronic device. Accordingly, since the second electronic device receives the touch signal and the pressure-sensitive signal, the touch operation of the second electronic device can be realized based on the pressure-sensitive signal and the touch signal.

[0060] See also Figure 4D , the stylus switches from the second electronic device to the Nth electronic device for touch operation, and the Nth electronic device can send a synchronization signal to the stylus in the uplink synchronization signal time slot through the touch communication connection, wherein the synchronization signal carries the ID number N; after receiving the ID number N, the stylus can send the Nth pressure-sensing signal to the Nth electronic device through the Bluetooth communication connection, wherein the Nth pressure-sensing signal is the pressure-sensing signal generated when the stylus contacts the touch screen of the Nth electronic device. Accordingly, since the Nth electronic device receives the touch signal and the pressure-sensing signal, the touch operation of the Nth electronic device can be realized based on the pressure-sensing signal and the touch signal.

[0061] It is understandable that the synchronization signal sent by each electronic device to the stylus is different. In other words, the synchronization signal sent by each electronic device carries the ID number corresponding to the electronic device.

[0062] From the above content, it can be seen that the stylus can assign corresponding ID numbers to multiple devices. Then, when the stylus touches different electronic devices, the different electronic devices can send corresponding synchronization signals to the stylus (that is, the synchronization signal will carry the ID number of the corresponding electronic device). In this way, the stylus can quickly identify which electronic device is currently performing a touch operation, and then quickly and accurately transmit the corresponding pressure signal to the corresponding electronic device through the Bluetooth connection, thereby helping to improve the switching efficiency of the stylus.

[0063] Combination of the above Figures 1 to 4D The method embodiment of the present application is described in detail. Figures 5 to 9 The device embodiment of the present application is described in detail. It should be understood that the description of the method embodiment corresponds to the description of the device embodiment, so the parts not described in detail can refer to the previous method embodiment.

[0072] The second communication module 610 is used to establish a first wireless communication connection with the stylus pen.

[0073] The third sending module 620 is configured to send device identification information of the first electronic device to the stylus via a second wireless communication connection if the stylus is switched from the second electronic device to the first electronic device for touch operation.

[0077] Optionally, the device identification information is a device ID number.

[0078] Optionally, the first wireless communication connection is a Bluetooth connection, a Wi-Fi connection or a Zigbee connection.

[0079] Figure 7 FIG. 1 shows a schematic diagram of the structure of a touch control system provided by an embodiment of the present application. Figure 7 As shown, the touch control system 700 may include an electronic device 710 and a stylus 720. The electronic device 710 may include a touch screen sensor 701, a sensor controller 702, and a system controller 703. The electronic device 710 may be any type of electronic device mentioned above.

[0080] The touch screen sensor 701 can be used to detect the touch signal sent by the stylus 720 to determine the position coordinates of the stylus on the touch screen. The sensor controller 702 is the main controller for bidirectional communication with the stylus 701. The sensor controller 702 sends a synchronization signal to the stylus 720 based on the touch communication via the touch screen sensor 701. The system controller 703 can establish Bluetooth communication with the stylus 720, and the stylus 720 can send a pressure signal to the system controller 703 through Bluetooth communication. In addition, the system controller 703 can perform system control on the functions of various parts of the electronic device 710 including the touch screen sensor 701 and the sensor controller 702. The system controller 703 can be, for example, a central processing unit (CPU), an application processor (AP), etc., and this application does not impose specific restrictions on this.

[0081] Understandably, Figure 7 The touch control system in can be used to implement the above-mentioned stylus switching method. As an example, the stylus 720 can assign an ID number (for example, an ID number 1) to the electronic device 710, and transmit the assigned ID number 1 to the system controller 703 via Bluetooth. The system controller 703 can transmit the ID number 1 to the sensor controller 702. If the stylus 720 switches from other electronic devices to the electronic device 710 for uplink touch operation, the sensor controller 702 can send a synchronization signal to the stylus via the touch screen sensor 701 in the uplink synchronization signal time slot, wherein the synchronization signal carries the ID number 1; after receiving the ID number 1, the stylus 720 can send a pressure signal to the system controller 703 via the Bluetooth communication connection, wherein the pressure signal is a pressure signal generated when the stylus 720 contacts the touch screen of the electronic device 710.
