[0046] Here, exemplary embodiments will be described in detail, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present disclosure.

[0047] The connection control method provided in the embodiments of the present disclosure can be applied to the application scenario where a stylus pen switches between different parameters of multiple electronic devices or the same electronic device. For example, it can be applied to the scenario where different display frame rates are switched between electronic devices such as mobile phones, tablet computers, and laptop computers, or the same electronic device.

[0048] If a stylus pen is to be switched between multiple electronic devices, the stylus pen needs to establish connections with multiple electronic devices and send downlink signals corresponding to different electronic devices. In the related art, there are problems such as reduced noise resistance of the stylus pen and slow switching speed between multiple electronic devices when transmitting configuration parameters with large amounts of information of different devices.

[0049] In view of this, an embodiment of the present disclosure provides a connection control method. In the connection control method provided by the present disclosure, the stylus receives an uplink signal containing an identifier, switches corresponding downlink configuration parameters based on the identifier, and sends the downlink signal to the corresponding electronic device.

[0050] Figure 1 The figure is a flow chart of a connection control method according to an exemplary embodiment.

[0051] In step S11, a first uplink signal sent by a first electronic device is received, where the first uplink signal includes a first identifier.

[0052] The first identifier is used to identify a display frame rate of the first electronic device, or to identify the first electronic device.

[0053] The uplink signal is a signal sent from the electronic device to the stylus. The uplink signal usually refers to an electric field signal sent from the detection electrode of the device touch screen to the stylus, which has the characteristics of low latency and real-time performance.

[0054] In the embodiment of the present disclosure, the uplink signal may be transmitted by carrying the uplink signal. For example, the electric field signal may be transmitted by carrying the electric field signal, such as electromagnetic waves.

[0055] In the disclosed embodiment, the identifier may be a number used to identify different electronic devices or different display frame rates of the same electronic device. For example, the identifier may be an identity document (ID). The identifier of device 1 with a display frame rate of 60 Hz is ID1, the identifier of device 1 with a display frame rate of 120 Hz is ID2, and the identifier of device 2 with a display frame rate of 60 Hz is ID3.

[0056] In step S12, based on the correspondence between the identifier and the downlink configuration parameter, a first downlink configuration parameter corresponding to the first identifier is obtained.

[0057] The downlink configuration parameter is a signal that specifies what waveform the stylus pen tip electrode produces at what time, and is related to factors such as the electronic device screen type, model, display frame rate, etc. For example, the downlink configuration parameter may be a downlink waveform signal timing format (time table).

[0058] In step S13, a first downlink signal is generated based on the first downlink configuration parameter, and the first downlink signal is sent to the first electronic device through the communication connection protocol.

[0059] The stylus generates a corresponding downlink signal according to the downlink configuration parameters corresponding to the identification information in the uplink signal and sends it to the corresponding electronic device through a communication connection protocol. The communication connection protocol may be near field communication (NFC), ultra wide band (UWB), Bluetooth, etc. The first downlink signal may be used to display the handwriting on the touch screen of the first electronic device.

[0060] In the disclosed embodiment, in response to receiving an uplink signal sent by an electronic device, the stylus pen sends a corresponding downlink signal using corresponding downlink configuration parameters based on an identifier in the uplink signal, thereby enabling the stylus pen to quickly switch between different electronic devices or different parameters of the same electronic device, thereby improving the user experience.

[0061] Figure 2 The figure is a flow chart of a method for switching a stylus pen according to an exemplary embodiment.

[0062] In step S21, a second uplink signal is received, and a second identifier is included in the second uplink signal, where the second identifier is used to identify a second downlink configuration parameter. The target device includes a second electronic device or a first electronic device, and the second downlink configuration parameter includes at least one of the following: a downlink configuration parameter of the second electronic device and a downlink configuration parameter of a different display frame rate of the first electronic device.

[0063] When the stylus is switched to a different electronic device for touch operation or the display frame rate of the electronic device currently being touched by the stylus changes, the electronic device sends an uplink signal containing an identifier to the stylus, wherein the identifier corresponds to a downlink configuration parameter required for the display frame rate of the different electronic device or the current electronic device to change.

[0064] In step S22, the first identifier is switched to the second identifier, and based on the corresponding relationship between the identifier and the downlink configuration parameter, the second downlink configuration parameter corresponding to the second identifier is obtained.

[0065] The stylus end stores multiple sets of downlink configuration parameters corresponding to different identifiers, and switches the corresponding downlink configuration parameters according to the received identifier.

[0066] In step S23, a second downlink signal is generated based on the second downlink configuration parameter, and the second downlink signal is sent through the communication connection protocol with the target device.

[0067] The stylus pen sends a corresponding downlink signal to the electronic device through a communication connection protocol according to the downlink configuration parameters corresponding to the identifier. The second downlink signal can be used to display the handwriting on the touch screen of the target electronic device.

[0068] Among them, the communication connection protocol can be near field communication (NFC), ultra wide band (Ultra Wide Band, UWB) technology, Bluetooth, etc.

[0069] In the disclosed embodiment, the stylus pen is connected to the electronic device through a communication connection protocol, and during the connection process, identification information and corresponding downlink configuration parameters. Such signals with large data volume and low real-time requirements are distributed and transmitted through the communication connection protocol, which can improve the anti-noise ability of the communication between the stylus pen and the electronic device and improve the utilization rate of channel resources.

[0070] Furthermore, the correspondence between multiple groups of downlink configuration parameters and identification information of the electronic device is stored by the stylus pen, thereby avoiding the problem of needing to obtain the corresponding downlink configuration parameters each time when the stylus pen communicates with the electronic device, thereby improving the transmission efficiency.

[0071] Figure 3 The invention is a flowchart showing a method for determining the number of connected electronic devices by a stylus according to an exemplary embodiment.

[0072] In step S31, the number of connected electronic devices is determined.

[0073] In step S32, if the number of connected electronic devices reaches the number threshold, the electronic device that first establishes a connection among the connected electronic devices is disconnected.

[0074] In the disclosed embodiment, by setting a threshold for the stylus pen to connect to an electronic device, the maximum number of connections between the stylus pen and the electronic device can be controlled. This can avoid performance degradation and communication conflicts caused by the stylus pen being connected to too many electronic devices at the same time. When the number of electronic device connections exceeds the threshold, the electronic device that first establishes a connection among the connected electronic devices is automatically disconnected to release connection resources, thereby ensuring the stability of subsequent connections and communication quality.

[0075] Figure 4 The present invention is a flowchart of a method for determining a corresponding relationship between an identifier and a downlink configuration parameter according to an exemplary embodiment.

[0076] In step S41, in response to the establishment of a communication connection between the stylus pen and the electronic device, an identifier allocation request sent by the electronic device is obtained, and an identifier is allocated.

[0077] After the stylus pen and the electronic device establish a communication connection through the communication connection protocol, the identification allocation request sent by the electronic device sub-device is obtained through the communication connection protocol used and an identification is allocated to the electronic device. For example, after the stylus pen and the electronic device are connected through Bluetooth pairing, in response to the identity document (ID) allocation request sent by the electronic device Bluetooth, ID1 is allocated to the electronic device.

[0078] In step S42, the downlink configuration parameters configured by the electronic device for the identifier are obtained, and a corresponding relationship between the downlink configuration parameters and the identifier is established.

[0079] After receiving the identifier sent by the stylus through the communication connection protocol, the electronic device combines the required downlink configuration parameters with the identifier and sends them to the stylus. The stylus creates a correspondence between the downlink configuration parameters and the identifier based on the received identifier and the corresponding downlink configuration parameters. Multiple sets of correspondences and corresponding downlink configuration parameters are stored on the stylus.

[0080] In the disclosed embodiment, by storing multiple sets of correspondences and corresponding downlink configuration parameters, the stylus can quickly switch to different configurations. When it is necessary to switch to another electronic device or the display frame rate of the same electronic device changes, there is no need to re-acquire the corresponding downlink configuration parameters, but directly use the stored corresponding combination to achieve fast switching. This can reduce the frequency and data volume of communication and improve communication efficiency.

[0081] In one embodiment, based on the communication address of the communication connection, the correspondences with the same communication address are divided into the same correspondence group, and the correspondence group includes different correspondences of the same electronic device.

[0082] For example, the stylus determines whether the stored downlink configuration parameters and corresponding relationships belong to the same electronic device according to the Media Access Control Address (MAC) address, and divides the corresponding relationships with the same communication address into the same corresponding relationship group. The same corresponding relationship group may include the corresponding relationships of downlink configuration parameters and identifiers of different display frame rates of the same electronic device.

[0083] In the disclosed embodiment, the correspondences with the same communication address are grouped into the same correspondence group, so that mutual interference between them can be avoided. When the stylus pen communicates with different electronic devices, communication failure or performance degradation will not occur due to channel conflict or interference.

[0084] In one embodiment of the present disclosure, during the communication process between the stylus pen and the electronic device, the electronic device needs to change the setting of the stylus pen, wherein the setting change operation can be a frequency hopping / voltage operation, which changes the frequency of the stylus pen communication signal or the voltage of the downlink signal. The identifier of the same electronic device in the same corresponding relationship group will respond to the setting change request operation of the electronic device.

[0085] During the communication between the stylus and the electronic device, frequency hopping / voltage operation will be performed. If the identification of the frequency hopping / voltage operation and the corresponding downlink configuration parameters do not belong to the same correspondence group and correspond to the same electronic device, it may cause the electronic device that sends the setting change request and the identification and corresponding downlink configuration parameters of the stylus that need to be changed to be inconsistent during the frequency hopping / voltage process, resulting in the failure of the frequency hopping / voltage operation.

[0086] This method can avoid interference from signals from other devices when the stylus responds to a setting change request from an electronic device.

[0087] Figure 5 The diagram is a schematic diagram showing a process of identifier allocation and parameter configuration according to an exemplary embodiment.

[0088] In the disclosed embodiment, the stylus pen and the electronic device perform identification assignment and parameter configuration via a communication connection protocol. For example, the stylus pen and the electronic device perform identification assignment and parameter configuration via Bluetooth.

[0089] After the first electronic device and the stylus are paired and connected via Bluetooth, the first electronic device Bluetooth sends an identification allocation request to the stylus Bluetooth, and the stylus Bluetooth allocates the first identification information to the first electronic device Bluetooth. After receiving the first identification information, the first electronic device is driven to combine it with the corresponding display frame rate a / b. For example, the display frame rate of the first device at this time can be 60HZ.

[0090] The first electronic device driver sends the first identifier to the touch firmware, and the touch firmware configures the identifier in the uplink signal according to the first identifier sent by the driver. The touch firmware has a default identifier, and when the device driver sends the first identifier to the touch firmware, the first identifier will replace the default identifier.

[0091] The first electronic device Bluetooth sends the first downlink configuration parameter corresponding to the first identifier and the MAC address of the device to the stylus Bluetooth.

[0092] The stylus Bluetooth saves the first downlink configuration parameter corresponding to the first identifier and the corresponding relationship for sending a downlink signal to the first electronic device using the first downlink configuration parameter when an uplink signal including the first identifier is received.

[0093] When the display frame rate of the first electronic device changes, the first electronic device Bluetooth sends an identification information allocation request to the stylus Bluetooth, and the stylus Bluetooth allocates a second identification to the first electronic device Bluetooth.

[0094] After receiving the second identifier, the first electronic device is driven to combine with the corresponding display frame rate a / b. For example, the device display frame rate may be 60HZ / 120HZ. For example, the display frame rate of the first device at this time may be 120HZ.

[0095] The first electronic device driver sends the second identifier to the touch firmware, and the touch firmware configures the identifier in the uplink signal according to the second identifier sent by the driver. The touch firmware has a default identifier, and when the device driver sends the second identifier to the touch firmware, the second identifier will replace the default identifier.

[0096] The first electronic device Bluetooth sends the second downlink configuration parameter corresponding to the second identifier and the MAC address of the device to the stylus Bluetooth.

[0097] The stylus Bluetooth saves the second downlink configuration parameter corresponding to the first identifier and the corresponding relationship for sending a downlink signal to the first electronic device using the second downlink configuration parameter when an uplink signal including the second identifier is received.

[0098] Figure 6 The figure is a flow chart of a connection control method according to an exemplary embodiment.

[0099] In step S71, in response to receiving a second uplink signal sent by a target device during the process of sending a third downlink signal to a first electronic device, the second uplink signal includes a second identifier.

[0100] Among them, the target device includes a second electronic device or a first electronic device, the first electronic device is an electronic device that is connected to communicate with the stylus, the second identifier is used to identify a second downlink configuration parameter, and the second downlink configuration parameter includes at least one of the following: a downlink configuration parameter of the second electronic device and a downlink configuration parameter of a different display frame rate of the first electronic device.

[0101] The third downlink signal may be the first downlink signal sent on the first electronic device according to the first downlink configuration parameter.

[0102] For example, the third downlink signal may be used to display handwriting on a touch screen of the first electronic device.

[0103] In step S72, based on the correspondence between the identifier and the downlink configuration parameter, a second downlink configuration parameter corresponding to the second identifier is obtained.

[0104] Since the stylus segment stores correspondence groups of different devices, which include correspondences between different downlink configuration parameters and identifiers, upon receiving the second uplink signal including the representation, the corresponding downlink configuration parameters are obtained according to the identifier.

[0105] In step S73, a second downlink signal is generated based on the second downlink configuration parameter, and the second downlink signal is sent through the communication connection protocol.

[0106] The second downlink parameter instructs the stylus to generate a corresponding second downlink signal, which is sent to the corresponding electronic device through the signal channel of different electronic devices established by the communication connection protocol. The second downlink signal can be used to display the handwriting on the touch screen of the target electronic device.

[0107] In the disclosed embodiment, in response to receiving an uplink signal sent by an electronic device to indicate switching, the stylus switches the corresponding downlink configuration parameters based on the identifier in the uplink signal and sends the corresponding downlink signal, without the need for the electronic device to repeatedly send the downlink configuration parameters in each communication. Through the method in the disclosed embodiment, the stylus can quickly switch between different electronic devices or different parameters of the same electronic device, thereby improving the user experience.

[0108] Figure 7 The figure is a flow chart of a connection control method according to an exemplary embodiment.

[0109] In step S81, a first uplink signal is sent to the stylus; the first uplink signal includes a first identifier; the first identifier is used to identify the display frame rate of the electronic device, or to identify the electronic device; the electronic device is an electronic device that is connected to the stylus for communication.

[0110] The electronic device can send an uplink signal to the stylus to instruct the stylus to perform a corresponding switch in response to the stylus switching device performing a touch operation or display frame rate change. The uplink signal includes an identifier that corresponds to the downlink configuration parameter of the electronic device.

[0111] In step S82, a first downlink signal is received through a communication connection protocol, the first downlink signal is generated based on a first downlink configuration parameter, and the first downlink configuration parameter corresponds to the first identifier.

[0112] Among them, the electronic device establishes different signal channels with different devices through the communication connection protocol for receiving downlink signals.

[0113] In the disclosed embodiment, by sending an uplink signal including an identifier having a corresponding relationship with the downlink configuration parameters of the electronic device, the electronic device can promptly notify the stylus to send a corresponding downlink signal according to the downlink parameter configuration corresponding to the device switching or display frame rate change. Such real-time indication can ensure that the stylus can respond quickly and make corresponding adjustments to adapt to the changes in the switching or display requirements of the electronic device without waiting for delays or other complex communication processes, thereby improving the efficiency and response speed of the switching.

[0114] Figure 8 The present invention is a flowchart of updating a default identification according to an exemplary embodiment.

[0115] In step S91 , in response to establishing a communication connection with the stylus, an identification allocation request is sent.

[0116] In step S92, an identifier assigned by the stylus pen to the electronic device is obtained.

[0117] In step S93, the default identification of the electronic device is updated based on the identification.

[0118] In the disclosed embodiment, the uplink signal reserves set data bits for real-time transmission of identification information, wherein the initial identification is a default identification configured for the touch layer of the device by the electronic device during the manufacturing process, and during the identification assignment and parameter configuration process of the stylus and the electronic device, the electronic device updates the default identification in the uplink signal through the touch firmware to be the identification assigned by the stylus to the electronic device.

[0119] By reserving a set data bit in the uplink signal for real-time transmission of identification information, the design and analysis process of the communication protocol can be simplified, and no additional message fields or protocols are required to transmit identification information, reducing the amount of communication data and the complexity of the communication protocol. In addition, sending the identification through the uplink signal can save communication resources and bandwidth and improve communication efficiency and real-time performance.

[0120] Fig. 9The figure is a schematic diagram showing a process of assigning identifications and configuring parameters of a stylus and an electronic device and switching the identifications according to an exemplary embodiment.

[0121] In one embodiment, the connection control method in the disclosed embodiment is used to switch the display frame rate of the same device and the stylus on different devices.

[0122] In the present disclosure, Figure 8 As shown, the stylus pen is paired and connected with the first electronic device and the second electronic device respectively via Bluetooth.

[0123] After the connection is established, the first electronic device requests the stylus pen for identification assignment according to different display frame rates, corresponding to different first downlink configuration parameters and second downlink configuration parameters, where the identifications may be ID1 and ID2. The second electronic device requests the stylus pen for identification assignment according to different third downlink configuration parameters, where the identification may be ID3. Identification assignment and parameter configuration of the stylus pen, the first electronic device, and the second electronic device are completed via Bluetooth.

[0124] In the application scenario of the stylus, the first electronic device responds to a change in display frame rate by sending identification ID2 to the stylus via an uplink signal. The stylus switches the corresponding downlink configuration parameters according to ID2 and sends a corresponding downlink signal through the Bluetooth signal channel with the first electronic device.

[0125] When the stylus performs a touch operation on the second electronic device, the second electronic device sends the identifier ID3 to the stylus via an uplink signal, and the stylus switches the corresponding downlink configuration parameters according to ID3 and sends a corresponding downlink signal through the Bluetooth signal channel with the second electronic device.

[0126] In the disclosed embodiment, by using an uplink signal including an identifier, switching between different electronic devices and fast switching of the display frame rate of the same electronic device are achieved, and the correspondence between multiple groups of identifiers and downlink configurations is stored on the stylus end, reducing the need to re-specify configuration parameters each time switching, simplifying the user's operating process, and improving the convenience of use and user experience.

[0127] Fig.10 The diagram is a schematic diagram showing a process of a stylus pen communicating with different types of electronic devices according to an exemplary embodiment.

[0128] In the disclosed embodiment, the stylus pen and the tablet computer and the personal computer (PC) are connected via Bluetooth Low Energy (BLE). When the display frame rate of the tablet computer changes or the stylus pen switches to the PC for touch operation, the stylus pen is notified to switch via an uplink signal. The method in the disclosed embodiment reduces the steps of re-specifying configuration parameters each time the switch is made, simplifies the user's operation process, and improves the convenience of use and user experience.
