[0002] This application claims priority to Chinese Patent Application No. 202410790277.2, filed on June 19, 2024, entitled "A Touch Method and Related Device", the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application relates to the field of terminal technology, and in particular to a touch control method and related equipment. Background Technology

[0004] Currently, most electronic products feature touchscreen displays. As user demands increase, the sensitivity of touchscreens is becoming more critical, making products with smooth touch response and timely feedback more attractive. Generally, the touch principle of a touchscreen involves collecting capacitance data, calculating the coordinate position based on that data, and then sending the coordinate position to the on-chip system for a response. This method requires the touchscreen to perform position coordinate calculations, meaning it needs a certain level of computing power. This makes it difficult to achieve very small areas and thicknesses for touchscreens, which conflicts with the concept of thinner and lighter products. Summary of the Invention

[0005] This application provides a touch control method and related device to reduce the probability of touch screen malfunction and improve the touch operation experience.

[0006] Firstly, a touch control method is provided, which can be applied to a display system. The display system includes a system-on-a-chip (SoC) and a touch display screen. The method includes: the touch display screen acquiring first capacitance data; the SoC receiving first information sent by the touch display screen, the first information including the first capacitance data; the SoC determining first position coordinates based on the first capacitance data, and responding based on the first position coordinates; the touch display screen acquiring second capacitance data; when the touch display screen determines that the display system meets a first condition, obtaining second position coordinates based on the second capacitance data; the SoC receiving second information sent by the touch display screen, the second information including the second position coordinates; and the SoC responding based on the second position coordinates.

[0007] In this embodiment, after the touch display screen collects the first capacitance data, it can directly send the first capacitance data to the on-chip system (SoC) without calculating the first position coordinates based on the first capacitance data. The SoC then calculates the position coordinates. This facilitates product thinning and lightness. Furthermore, due to the powerful computing capabilities of the SoC, calculating the position coordinates by the SoC improves accuracy and reduces the probability of touch malfunction. In this embodiment, there are two interaction mechanisms between the touch display screen and the SoC. One is that the touch display screen sends capacitance data to the SoC, and the other is that the touch display screen sends position coordinates to the SoC. In the first mechanism, the computing power (the process of calculating the position coordinates) is borne by the SoC; in the second mechanism, the computing power is borne by the touch display screen. These two interaction mechanisms can be switched. For example, if the display system meets a first condition, the interaction between the touch display screen and the SoC switches from the first interaction mechanism to the second interaction mechanism. Compared to solutions where the computing power is solely provided by the touch display (i.e., only supporting the second interaction mechanism), the technical solution provided in this application is more flexible and has a lower probability of touch malfunction.

[0008] In one possible design, the system-on-a-chip includes a first driver and a second driver, both of which are drivers for the touch display screen. The first driver supports the first driver protocol, and the second driver supports the second driver protocol. The system-on-a-chip receives first information sent by the touch display screen, including: when the system-on-a-chip runs the first driver, it receives the first information sent by the touch display screen, the first information being based on the first driver protocol. The system-on-a-chip receives second information sent by the touch display screen, including: when the system-on-a-chip runs the second driver, it receives the second information sent by the touch display screen, the second information being based on the second driver protocol.

[0009] In this embodiment, the display system supports dual drivers (i.e., a first driver and a second driver). For example, if the system-on-chip (SoC) and the touch display communicate based on the first driver, and the display system meets a first condition (e.g., the first driver malfunctions), then the SoC and the touch display communicate based on the second driver. Therefore, compared to a single-driver solution for the display system, the dual-driver solution provided in this embodiment reduces the probability of touch display failure and improves the touch operation experience.

[0010] In one possible design, when the system-on-a-chip (SoC) runs the first driver, receiving first information sent by the touch display screen includes: when the SoC runs the first driver, reading the first information from a first cache of the touch display screen; when the SoC runs the second driver, receiving second information sent by the touch display screen includes: when the SoC runs the second driver, reading the first information from a second cache of the touch display screen.

[0011] In this embodiment, the touch display screen includes a first cache and a second cache. Information in the first cache conforms to a first driving protocol, and information in the second cache conforms to a second driving protocol. The system-on-a-chip (SoC) can read information from the first cache by running the first driver and read information from the second cache by running the second driver. This enables communication between the touch display screen and the SoC based on dual drivers.

[0012] Optionally, the on-chip system may respond based on the first or second position coordinates, which may include: the on-chip system updating the displayed content at the first or second position coordinates, such as displaying editing content such as a cursor, text, lines, or drawings at the first or second position coordinates.

[0013] Optionally, the on-chip system determines the first position coordinates based on the first capacitance data and responds based on the first position coordinates. This can include: the on-chip system determines the first position coordinates and a first operation type based on the first capacitance data, and responds based on the first operation type and the first position coordinates. The first operation type can include: single-click operation, double-click operation, long-press operation, swipe operation, etc. In this approach, the on-chip system can respond differently to different operation types.

[0014] Optionally, when the touch display determines that the display system meets the first condition, obtaining the second position coordinates based on the second capacitance data may include: when the touch display determines that the display system meets the first condition, obtaining the second position coordinates and a second operation type based on the second capacitance data; the second information received by the on-chip system includes the second position coordinates and the second operation type; and the on-chip device responds based on the second position coordinates and the second operation type. The second operation type may include: single-click operation, double-click operation, long-press operation, swipe operation, etc.

[0015] In one possible design, the first driver is the Touch Master Process (THP) driver, and the second driver is the Hardware Interface Device (HID) driver.

[0016] It should be noted that the first driver and the second driver can be other drivers, and this application embodiment does not limit them. Optionally, the first driver and the second driver can be the same or different.

[0017] In one possible design, the display system satisfies a first condition, including at least one of the following: the first driver is malfunctioning; the on-chip system is currently running a second system; the on-chip system is currently running a second preset application; the on-chip system's operating load is greater than or equal to a first preset load; the touch display screen's operating load is less than or equal to a second preset load; and the on-chip system receives a second operation, the second operation being used to instruct a switch from the first driver to the second driver.

[0018] In this embodiment, the display system supports dual drivers, namely a first driver and a second driver. When communication between the system-on-chip (SoC) and the touchscreen is based on the first driver, if the first driver malfunctions, or is running on a second system, or is running a second preset application, or is under a load exceeding a preset load, or receives a user switching operation, the SoC and the touchscreen communicate based on the second driver to ensure uninterrupted transmission between the touchscreen and the SoC. Compared to a single-driver solution for the display system, this dual-driver solution reduces the probability of touchscreen malfunction and improves the touch operation experience.

[0019] In one possible design, the method further includes: the touch display acquiring third capacitance data; when the touch display determines that the display system meets the second condition, sending third information to the system-on-a-chip, the third information being based on the first driving protocol and including the third capacitance data; the system-on-a-chip determining third position coordinates based on the third capacitance data and responding based on the third position coordinates.

[0020] In this embodiment, the display system supports dual drivers, namely a first driver and a second driver. When the system-on-chip (SoC) and the touch display screen communicate based on the second driver, if the display system meets a second condition, it switches to the first driver for communication to ensure that the transmission channel between the touch display screen and the SoC is uninterrupted and to reduce the probability of touch failure.

[0021] In one possible design, the display system satisfies a second condition, including at least one of the following: the first driver returns to normal; the second driver malfunctions; the on-chip system is currently running the first system; the on-chip system is currently running the first preset application; the on-chip system's operating load is less than the first preset load; the touch display screen's operating load is greater than the second preset load; the on-chip system receives a first operation, the first operation being used to instruct a switch from the second driver to the first driver.

[0022] In this embodiment, the display system supports dual drivers, namely a first driver and a second driver. When communication between the on-chip system and the touch display is based on the second driver, if the first driver recovers, or is running on the first system, or running a first preset application, or its load is below a preset load, or a user switching operation is received, communication between the on-chip system and the touch display is based on the first driver to ensure uninterrupted transmission between the touch display and the on-chip system. Compared to a single-driver solution for the display system, this dual-driver solution reduces the probability of touch display failure and improves the touch operation experience.

Optionally, the first interface and the second interface can be the same type of interface or different types of interfaces, and this is not limited.

[0027] In one possible design, the first information and / or the second information further include first indication information, which is used to instruct the on-chip system to receive other data through a short-range communication module. The other data includes at least one of pressure data, angle data, and acceleration data.

[0028] In this embodiment of the application, the on-chip system can receive pressure data, angle data, acceleration data, etc. through a short-range communication module (e.g., Bluetooth). In this way, pressure data, angle data, acceleration data, etc. do not need to be carried in the first information and / or the second information, which can save the number of bytes of the first information and / or the second information and reduce the data transmission volume of the driver.

[0029] In one possible design, the method further includes: the on-chip system controlling the first driver to be disabled.

[0031] In one possible design, the method further includes: the touch display screen outputting a first prompt message, the first prompt message being used to indicate that the display system has entered a second mode, the second mode being a mode that implements touch functionality based on the second driver.

[0038] In this embodiment, the dual-drive switching between the system-on-a-chip and the touch display (e.g., switching from the second driver to the first driver) is confirmed by the user, resulting in a better user experience.

[0157] The following explanations of some terms used in the embodiments of this application are provided to facilitate understanding by those skilled in the art.

[0158] The embodiments of this application involve at least one, including one or more; where "multiple" means two or more. Furthermore, it should be understood that in the description of this specification, terms such as "first" and "second" are used only for descriptive purposes and should not be construed as indicating or implying relative importance or order. For example, "first driver" and "second driver" do not represent the degree of importance of the two or their order, but are merely for descriptive distinction. In the embodiments of this application, "and / or" merely describes an association relationship, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, and B alone. Additionally, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship.

[0159] The directional terms mentioned in the embodiments of this application, such as "up", "down", "left", "right", "inner", and "outer", are only for reference to the directions in the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of this application, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this application.

[0160] References to "one embodiment," "in some examples," or "some embodiments" as described in this specification mean that one or more embodiments of this specification include a particular feature, structure, or characteristic described in connection with that embodiment. Therefore, the phrases "in some examples," "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized. The terms "comprising," "including," "having," and variations thereof mean "including but not limited to," unless otherwise specifically emphasized.

[0161] The touch control method provided in this application can be applied to electronic devices. The electronic device can be any device with a touch display screen. For example, the electronic device can be a mobile phone, tablet computer, laptop computer, personal computer (PC), ultra-mobile personal computer (UMPC), netbook, personal digital assistant (PDA), or other portable devices; or it can be an entertainment device such as a television set or game console; or it can be a wearable device such as a watch or bracelet; or it can be an in-vehicle device, such as a device installed in a vehicle, like a display device; of course, the vehicle can also be replaced by other vehicles or transportation tools such as trains, aircraft, or mobile platforms; or it can be a virtual reality (VR) device, augmented reality (AR) device, mixed reality (MR) device, etc. In short, this application does not limit the specific type of electronic device. For ease of understanding, this document mainly uses a laptop computer or tablet computer as an example for explanation; optionally, the laptop computer can be a 2-in-1 laptop.

[0162] In this embodiment of the application, the operating system (OS) of the electronic device can be any type of operating system, for example, it can be Etc. For ease of understanding, this article mainly uses... Let's take an example to illustrate.

[0163] In this embodiment, the electronic device has touch functionality. For example, the electronic device may include a touch device for implementing touch functionality. Optionally, the touch device may include any type of device such as a touch screen, touchpad, gamepad, keyboard, or mouse; this embodiment is not limited thereto. Optionally, the touch device and the electronic device may be an integrated design or a separate design. Taking an integrated design as an example, the touch device may be integrated into the electronic device; for example, the electronic device integrates a touch screen and / or touchpad. Taking a separate design as an example, the touch device and the electronic device may be two completely independent devices; for example, the touch device is connected to the electronic device, and the connection may include a wired connection or a wireless connection. Taking a wired connection as an example, the electronic device may provide an interface for wired connection to the touch device. The interface may be, for example, a Universal Serial Bus (USB) interface or other interfaces. For ease of understanding, this document uses an electronic device integrating a touch screen as an example for explanation.

[0164] For example, please refer to Figure 1, which is a schematic diagram of a display system provided in an embodiment of this application. The display system can be installed in an electronic device, which can be various devices listed above, such as laptops, tablets, etc. As shown in Figure 1, the display system includes a system on a chip (SOC) and a touch screen. It should be understood that Figure 1 only shows some of the components in the display system related to the embodiment of this application. In fact, the display system may include more components than those shown in Figure 1, which are not listed here.

[0165] As shown in Figure 1, the System-on-a-Chip (SOC) can be understood as the nerve center and command center of the display system, responsible for processing various tasks. For example, an SOC may include one or more processors, such as an application processor (AP), a modem processor, a graphics processing unit (GPU), an image signal processor (ISP), a controller, memory, a video codec, a digital signal processor (DSP), a baseband processor, a neural network processing unit (NPU), etc.

[0166] As shown in Figure 1, a touch display screen can include a display panel (DP) and a touch panel (TP). The display panel is used to display information such as images, videos, and text. Optionally, the display panel can be a liquid crystal display (LCD), an organic light-emitting diode (OLED), an active-matrix organic light-emitting diode (AMOLED), a flexible light-emitting diode (FLED), a miniature LED, a microLED, a quantum dot light-emitting diode (QLED), etc. The touch panel supports operation by the user's fingers, stylus, or any suitable object or accessory on or near the touch panel. Optionally, the touch panel can be implemented using any of the following technologies: resistive, capacitive, infrared, and surface acoustic wave; of course, other technologies that may be used in the future are also possible. Taking a touch panel employing capacitive technology as an example, when a user operates the touch panel using a finger, stylus, or any suitable object or accessory, the capacitance on the touch panel changes, generating capacitance data. This capacitance data can be used to calculate the specific operation position (e.g., position coordinates) to accurately respond to the operation. It should be noted that Figure 1 illustrates an example where the display panel is located below the touch panel, and the touch panel is disposed on the surface of the electronic device. However, this embodiment does not limit the positional relationship between the display panel and the touch panel.

[0167] As shown in Figure 1, the touch display screen may include a Touch Panel Integrated Circuit (TPIC). The TPIC is connected to the touch panel and can be understood as the processing center of the touch panel. Taking a touch panel using capacitive technology as an example, the TPIC can be used to collect capacitance data generated on the touch panel. Optionally, it can also perform calculations on the capacitance data, such as calculating the specific operation position (e.g., position coordinates) based on the capacitance data. It should be noted that Figure 1 shows the TPIC located inside the touch display screen as an example. It should be understood that, in order not to obstruct the touch panel and display panel, the TPIC can be placed at the edge of the touch display screen (e.g., a non-display area). Of course, the TPIC can also be located in other positions. For example, if the touch display screen is full-screen, the TPIC can be located behind the touch display screen, or the TPIC can be located outside the touch display screen. In short, the embodiments of this application do not limit the position of the TPIC.

[0168] The following text continues to use Figure 1 as an example to illustrate the touch method provided in the embodiments of this application.

[0169] In Figure 1, the SOC needs to respond to user actions on the touch panel, so communication needs to be established between the TPIC and the SOC for information exchange. One possible approach is that the SOC includes a driver for the touch display, which is used to implement information transmission between the TPIC and the SOC. For ease of understanding, a driver (hereinafter referred to as "driver") will be briefly explained first. A driver is a software program used to enable normal communication between the SOC and other hardware. The SOC may include more than one driver; for example, it may also include hardware such as graphics cards, sound cards, and network cards, which would then have corresponding graphics card drivers, sound card drivers, and network card drivers to enable the graphics card, sound card, and network card to function properly. Alternatively, if other hardware (e.g., mouse, keyboard, gamepad) is connected, the SOC can install the corresponding drivers to enable the other hardware to function properly.

[0170] In some embodiments, the driver for the touch display screen can be a Hardware Interface Device (HID) driver. For example, as shown in Figure 2A, the TPIC and SOC communicate via an HID driver. It should be understood that when the TPIC and SOC transmit information via the HID driver, they need to meet certain protocols, such as the HID standard protocol (HID protocol for short). This protocol can specify the format and content of the transmitted information. Taking the HID protocol's specification that the information transmitted by the TPIC to the SOC is position coordinates as an example, after the TPIC collects the capacitance data on the touch panel, it needs to calculate the position coordinates based on the capacitance data, and then send the position coordinates to the SOC via the HID driver based on the HID protocol. Therefore, the TPIC needs to have a certain computing power to calculate the position coordinates based on the capacitance data. One possible approach is that the TPIC includes a processing unit (not shown in Figure 2A) used to calculate the position coordinates based on the capacitance data. Considering factors such as the area and cost of the touch panel, the processing unit can be a small processing unit or a micro processing unit, such as a micro control unit (MCU). Therefore, the computing power of the processing unit is limited. Once the load is too heavy, it will be unable to calculate the specific position coordinates of the operation, which can easily lead to touch failure.

[0171] Optionally, the electronic device can display the HID driver in a certain way. For example, after the electronic device is powered on, the user can view the HID driver in the electronic device. For example, in response to user operation, the electronic device opens the Device Manager interface, which can display relevant information about the HID driver. For example, please refer to Figure 2B, which is a schematic diagram of the Device Manager interface in the electronic device. As shown in Figure 2B, the Device Manager interface includes a directory, which includes an option for human input devices. Under this option, there is an identifier 201, and optionally, an identifier 202. Identifier 201 is used to indicate the HID driver. For example, identifier 201 can be "I2C HID device". Identifier 202 is used to indicate a touch screen in the electronic device that conforms to the HID standard protocol. It should be noted that the embodiments of this application do not limit the form of identifiers 201 and 202, and they can be various types of text, icons, images, etc.

[0172] In this embodiment of the application, the above-mentioned mode in which the computing power is undertaken by TPIC can be called the Touch Post Process (TPP) mode.

[0173] As mentioned earlier, the TPIC has limited computing power, and excessive workload can lead to touch malfunction. To alleviate the computing burden on the TPIC, one possible approach is to transfer the TPIC's computing power to the SOC, whereby the SOC handles the calculation process from capacitance data to position coordinates. In this way, the TPIC only needs to send the collected capacitance data to the SOC, without needing to calculate position coordinates, thus reducing computing power. However, in this method, the information transmitted by the TPIC to the SOC is capacitance data, not position coordinates, so it cannot be transmitted using the HID driver. One solution is to use a Touch Host Process (THP) driver for the touch display. For example, as shown in Figure 3A, the TPIC and SOC communicate via the THP driver. The difference between the THP driver and the HID driver is that the HID driver supports the HID protocol, which specifies that the transmitted content is position coordinates; the THP driver supports the THP protocol, which specifies that the transmitted content can be capacitance data. Therefore, in Figure 3A, the TPIC can send the collected capacitance data to the SOC via the THP driver based on the THP protocol, and the SOC can calculate the position coordinates based on the capacitance data. In this way, the computing power of TPIC is transferred to SOC, and SOC has powerful computing power, which can improve the accuracy of calculation to a certain extent.

[0174] Optionally, the electronic device can display the THP driver in a certain way. For example, after the electronic device is powered on, the user can view the THP driver in the electronic device. For example, in response to user operation, the electronic device opens the Device Manager interface, which can display relevant information about the THP driver. For example, please refer to Figure 3B, which is a schematic diagram of the Device Manager interface in the electronic device. As shown in Figure 3B, the Device Manager interface includes a directory, which includes an option for human input devices. Under this option, there is an identifier 301, and optionally, an identifier 302. Identifier 301 is used to indicate the THP driver. For example, identifier 301 can be "USB THP device". Identifier 302 is used to indicate a touch screen that conforms to the THP standard protocol. It should be noted that the form of identifiers 301 and 302 is not limited in this embodiment of the application, and they can be various types of text, icons, images, etc.

[0175] In this embodiment of the application, the above-mentioned TPIC computing power transfer mode to SOC can be called the Touch Host Process (THP) mode.

[0176] The above embodiments illustrate two modes: TPP mode and THP mode. TPP mode corresponds to the HID driver, and THP mode corresponds to the THP driver. In the embodiments of this application, the display system may support only TPP mode, only THP mode, or both TPP and THP modes. Taking TPP mode as an example, the display system may include the HID driver but not the THP driver. Taking THP mode as an example, the display system may include the THP driver but not the HID driver. Whether only TPP mode or THP mode is supported, a single driver is used. If this driver malfunctions, touch malfunction will occur. Therefore, in the following embodiments, the display system that supports both TPP and THP modes is used as an example, that is, the display system includes dual drivers, the HID driver and the THP driver. When one driver malfunctions, the other driver can be used for communication, which reduces the probability of touch malfunction compared to the single-driver approach.

[0177] The following description, in conjunction with the accompanying drawings, illustrates the dual-drive touch control scheme provided in the embodiments of this application.

[0178] Please refer to Figure 4A, which is a schematic diagram of a display system provided in an embodiment of this application. The display system can be disposed in an electronic device, which can be various devices listed above, such as laptops and tablets. As shown in Figure 4A, the display system includes a System-on-Chip (SOC) and a touch display screen. Please refer to the previous description of the SOC and touch display screen; for the sake of brevity, they will not be repeated here. As shown in Figure 4A, the SOC includes a first driver and a second driver, both of which are used to implement communication between the SOC and the TPIC.

[0179] In some embodiments, the first driver and the second driver can be the same. For example, both the first driver and the second driver are HID drivers (see the previous section for information on HID drivers); or, both the first driver and the second driver are THP drivers (see the previous description for information on THP drivers). Alternatively, the first driver and the second driver can also be different. For example, the first driver is an HID driver and the second driver is a THP driver; or, the first driver is a THP driver and the second driver is an HID driver. Wherein, the first driver supports a first protocol, and the second driver supports a second protocol. Optionally, the first protocol and the second protocol can be the same or different. For example, when both the first driver and the second driver are HID drivers, both the first protocol and the second protocol are HID protocols (see the previous description for information on HID protocols). Alternatively, when both the first driver and the second driver are THP drivers, both the first protocol and the second protocol are THP protocols (see the previous description for information on THP protocols). Alternatively, when the first driver is a THP driver and the second driver is an HID driver, the first protocol is the THP protocol, and the second protocol is the HID protocol. For ease of explanation, the following embodiments are described using the example of a THP driver and a HID driver.

[0180] Optionally, the electronic device can display the dual drivers in a certain way. For example, after the electronic device is powered on, the user can view the dual drivers in the electronic device. For example, in response to user operation, the electronic device opens the device manager interface, which can display relevant information about the dual drivers. For example, please refer to Figure 4B, which is a schematic diagram of the device manager interface in the electronic device. As shown in Figure 4B, the device manager interface includes a directory, which includes options for human body input devices, and under these options are identifiers 401, 402, 403, and 404. The order of these four identifiers is not limited in this embodiment. Identifier 401 is used to indicate the HID driver. Identifier 402 is used to indicate a touch screen in the electronic device that conforms to the HID standard protocol. Identifier 403 is used to indicate the THP driver. Identifier 404 is used to indicate a touch screen in the electronic device that conforms to the THP standard protocol. It should be understood that the touch screen indicated by identifiers 402 and 404 is the same, that is, the electronic device has only one touch screen, but corresponds to two touch drivers, namely the HID driver and the THP driver.

[0181] The following section continues to use Figure 4A as an example to illustrate the dual-drive touch method provided in the embodiments of this application.

[0182] For example, please refer to Figure 5, which is a flowchart illustrating a touch method provided in an embodiment of this application. This method can be applied to a display system, such as the structure shown in Figure 4A. The display system can be located in an electronic device, which can be one of the devices listed above, such as a laptop or tablet computer. As shown in Figure 5, the process includes:

[0183] S501, TPIC obtains system status information.

[0184] Optionally, the system status information may include at least one of information a to information e. Information a indicates the system currently running on the electronic device. For example, information a may be the identifier, name, etc., of the currently running system. In this embodiment, the electronic device may include more than one system. Taking two systems as an example, such as a first system and a second system, when the electronic device is currently running on the first system, information a indicates the first system; when the electronic device is currently running on the second system, information a indicates the second system. As an example, the first system may be the main operating system, such as the Windows system (Win OS), and the second system may be, for example, a pre-operating system, such as a pre-OS system. The pre-OS system may include: a system entered after the electronic device is powered on but before loading the main operating system, or a system entered after a restart. Optionally, the restart may involve system partitioning, modification of critical system files, or other restarts related to the operating system. As another example, the first system may be a host system, and the second system may be a guest system. The host system may be an operating system running on the hardware of the electronic device, and the guest system can be understood as an operating system running in a virtual machine or container within the electronic device. Information b indicates whether the first driver is abnormal. For example, when the first driver is normal, information b is represented by 1; when the first driver is abnormal, information b is represented by 0. Information c is used to indicate whether the second driver is abnormal. For example, when the second driver is normal, information c is represented by 1; when the second driver is abnormal, information c is represented by 0. Information d is used to indicate the application currently running on the electronic device. For example, information d may include the name of the currently running application. Optionally, the currently running application may include a foreground application and / or a background application. Information e is used to indicate the current operating load of the electronic device. Optionally, the current operating load can be described by at least one of CPU utilization and memory resource utilization. The foregoing has listed several specific pieces of information included in the system status information. It is understood that the system status information may contain more information, which is not limited in the embodiments of this application.

[0185] Optionally, one possible way for the TPIC to obtain system status information is that the TPIC and the SOC can be connected through a third interface, and the TPIC receives the system status information sent by the SOC through the third interface. For example, the third interface can be a general-purpose input / output (GPIO) interface or other interfaces; this embodiment is not limited to this. In this approach, the SOC needs to collect system status information. One possible way is that the SOC includes applications and / or functions for monitoring system status, and these applications and / or functions can collect system status information in real time. Optionally, the applications and / or functions can be system-level applications and / or functions, or they can be third-party applications and / or functions. For example, the applications and / or functions can be monitoring applications, such as mobile phone management applications, PC management applications, etc.

[0186] S502, TPIC determines whether to use the first mode (e.g., THP mode) or the second mode (e.g., TPP mode) based on the system status information. If the first mode is used, execute S503; if the second mode is used, execute S504.

[0187] In this embodiment of the application, S502 may include at least one of the following:

[0188] Method 1: The TPIC uses the first mode when it determines the currently running system is the first system based on system status information; otherwise, it uses the second mode. For example, the system status information includes information 'a', which indicates the currently running system. The TPIC can determine whether the currently running system is the first system based on information 'a'. As mentioned earlier, the first system is the main operating system or host system, and the second system is the pre-operating system or client system. In this embodiment, considering the high touch demand under the main operating system or host system, if the second mode (TPP mode) is used, the TPIC cannot handle the excessive computing power, which could easily lead to touch malfunction. Therefore, under the main operating system or host system, the first mode (i.e., THP mode) is used to reduce the probability of touch malfunction.

[0189] Method 2: TPIC uses the first mode if the first driver is functioning normally based on system status information; otherwise, it uses the second mode. For example, the system status information includes information b, which indicates whether the first driver is malfunctioning. TPIC can determine whether the first driver is malfunctioning based on information b.

[0190] Method 3: If TPIC determines that the second driver is malfunctioning based on system status information, it uses the first mode; otherwise, it uses the second mode. For example, the system status information includes information c, which indicates whether the second driver is malfunctioning. TPIC can determine whether the second driver is malfunctioning based on information c.

[0191] Method 4: Based on system status information, TPIC determines if the currently running application is the first preset application and uses the first mode; otherwise, it uses the second mode. For example, the first preset application could be an application with high touch requirements, such as a drawing application, a game application, or a conferencing application. Considering that if an application has high touch requirements, using the second mode (TPP mode) would overload TPIC with excessive computing power, potentially leading to touch malfunctions, the first mode (THP mode) is used to reduce the probability of touch malfunctions. One possible way for TPIC to determine if the currently running application is the first preset application is as follows: the system status information includes information 'd', which indicates the currently running application. TPIC can determine the currently running application based on information 'd'. Then, TPIC determines whether the currently running application is the first preset application based on the currently running application and the preset application list. For example, if the application identifier of the currently running application exists in the preset application list, it is determined that the currently running application is the first preset application; otherwise, it is determined that the currently running application is not the first preset application. Optionally, the preset application list can be pre-configured.

[0192] Method 5: TPIC determines the current operating load based on system status information. If the current load is less than or equal to a preset load, it uses the first mode; otherwise, it uses the second mode. For example, the system status information includes information 'e', ​​which indicates the current operating load. TPIC determines the current operating load based on information 'e' and compares it with the preset load. As mentioned earlier, in the first mode, the computing power is borne by the SOC. Considering that using the first mode would increase the SOC's load and cause device lag when the SOC load is high, the second mode (where the computing power is borne by TPIC) can be used when the SOC load is high, and the first mode (where the computing power is borne by the SOC) is used when the SOC load is low.

[0193] Optionally, there can be a certain priority order among the methods one through five. For example, the priority order is: Method two / three > Method one > Method five > Method four. Method two and method three can have the same priority. The method with higher priority is used first to determine whether to use the first mode or the second mode. If the specific mode cannot be determined, then the method with lower priority is used for determination. For example, TPIC first uses methods two and three to determine the mode. Suppose that method two determines the first mode (first driver is normal), and method three determines the second mode (second driver is normal), meaning the specific mode cannot be determined. Then, methods one, five, four, etc., can be used for further determination according to the aforementioned priority relationship.

[0194] S503, in the first mode, the TPIC sends first information to the SOC via the first driver. The first information includes first capacitance data, so that the SOC can calculate the first position coordinates based on the first capacitance data. As mentioned above, the first driver is a THP driver, which supports the THP protocol. The THP protocol specifies that the information transmitted by the TPIC to the SOC can be capacitance data. Therefore, if the TPIC uses the first mode, it can send the collected first capacitance data to the SOC via the THP driver.

[0195] Optionally, the TPIC sends the first information to the SOC via the first driver, which may include: the TPIC writing the first information into the first cache, the first information conforming to the THP protocol, and the SOC running the first driver (i.e., the THP driver) to read the first information from the first cache. For example, the first driver includes the address information of the first cache, so the SOC running the first driver can read the first information from the first cache based on the address information.

[0196] In some embodiments, the first information includes one or more fields, and the first field of the one or more fields includes first capacitance data. The first field may be a field specified in the THP protocol for storing capacitance data.

[0197] In other embodiments, the first information may also include other data, such as pressure data. This is because when a user operates on the touchscreen, the TPIC can collect not only the first capacitance data but also other data, such as pressure data. One possible approach is to include a pressure sensor within the touchscreen, which can sense the pressure applied by the user on the touchscreen and send the pressure data to the TPIC. In some scenarios (e.g., drawing scenarios), the SOC needs to respond differently depending on the pressure applied by the user on the touchscreen; for example, thicker lines are drawn when the pressure is greater, and thinner lines are drawn when the pressure is less. Therefore, the TPIC needs to transmit the pressure data to the SOC for response. Thus, the first information also includes pressure data. As an example, please refer to Figure 6A(a), which is a schematic diagram of the first information. As shown in Figure 6A(a), the first information includes the first capacitance data and other data, such as pressure data. It should be noted that pressure data is mainly used as an example here, but other data can also be used, and this application embodiment is not limited to this.

[0198] Optionally, the other data may not need to be included in the first information, but can be sent to the SOC through other means. An exemplary scenario is that the stylus includes a pressure sensor, Bluetooth, etc. When a user operates the stylus on the touchscreen, the pressure sensor in the stylus can sense the pressure data and send it to the SOC via Bluetooth. Therefore, the pressure data is transmitted to the SOC by the stylus via Bluetooth, without the TPIC needing to transmit pressure data to the SOC. Optionally, in this case, to prompt the SOC to receive the pressure data via Bluetooth, one possible approach is that the first information includes first indication information, which instructs the SOC to receive the pressure data via Bluetooth. As an example, please refer to Figure 6A(b), which is another schematic diagram of the first information. As shown in Figure 6A(b), the first information includes first capacitance data and first indication information, which instructs the SOC to receive the pressure data via Bluetooth. It should be noted that this mainly uses pressure data as an example, but other data can also be used, such as angle data, acceleration data, etc. For example, the stylus includes an angle sensor to detect the angle between the stylus and the touchscreen. For example, the stylus includes an accelerometer to detect the stylus's acceleration.

[0199] If we refer to the form of the first information in Figure 6A(a) as the first form, and the form of the first information in Figure 6A(b) as the second form, the electronic device can use either the first or the second form depending on the actual scenario. For example, the first form is used when the user's finger is operating on the touch screen, and the second form is used when a stylus is operating on the touch screen.

[0200] Optionally, in the first mode, the TPIC and SOC communicate via a first driver, which may include: the TPIC and SOC communicating via a first interface, where the first interface corresponds to the first driver. The first interface can be various types of interfaces, such as an inter-integrated circuit (I2C) interface, a serial peripheral interface (SPI), a pulse code modulation (PCM) interface, a universal asynchronous receiver / transmitter (UART) interface, a mobile industry processor interface (MIPI), a general-purpose input / output (GPIO) interface, a universal serial bus (USB) interface, etc.

[0201] S504, in the second mode, the TPIC sends second information to the SOC via the second driver. This second information includes second position coordinates, which are calculated based on the second capacitance data generated by the touch panel. As mentioned earlier, the second driver is an HID driver, supporting the HID protocol. The HID protocol specifies that the information transmitted by the TPIC to the SOC is position coordinates. Therefore, when the TPIC uses the second mode, it needs to calculate the collected second capacitance data into second position coordinates and then send these coordinates to the SOC via the HID driver.

[0202] Optionally, the TPIC sends second information to the SOC via a second driver. This can include: the TPIC writing the second information into a second cache, the second information conforming to the HID protocol; and the SOC running the second driver (i.e., the HID driver) to read the second information from the second cache. For example, the second driver includes the address information of the second cache, so the SOC running the second driver can read the second information from the second cache based on the address information. Optionally, the second cache is a different cache from the first cache mentioned above.

[0203] In some embodiments, the second information includes one or more fields, and the second field among the one or more fields includes second location coordinates. The second field may be a field specified in the HID protocol for placing location coordinates.

[0204] In other embodiments, the second information may also include other data, such as pressure data. The reason for including pressure data in the second information is explained above and will not be repeated here. As an example, please refer to Figure 6B(a), which is a schematic diagram of the second information. The second information includes second position coordinates and other data, such as pressure data.

[0205] Optionally, the other data may not need to be included in the second information, but can be sent to the SOC through other means. For example, in the case of a stylus, pressure data can be sent to the SOC by the stylus via Bluetooth; please refer to the previous description for the specific principle. Optionally, to prompt the SOC to receive pressure data via Bluetooth, one possible approach is that the second information includes second indication information, which instructs the SOC to receive pressure data via Bluetooth. As an example, please refer to Figure 6B(b), which is another schematic diagram of the second information. The second information includes second position coordinates and also includes second indication information.

[0206] If we refer to the form of the second information in Figure 6B(a) as the first form, and the form of the second information in Figure 6B(b) as the second form, the electronic device can use either the first or the second form depending on the actual scenario. For example, the first form is used when the user's finger is operating on the touch screen, and the second form is used when a stylus is operating on the touch screen.

[0207] Optionally, in the second mode, the TPIC and SOC communicate via a second driver, which may include: the TPIC and SOC communicating via a second interface, where the second interface corresponds to the second driver. The second interface can be various types of interfaces, such as I2C, SPI, PCM, UART, MIPI, GPIO, USB, etc. The second interface can be the same type as the first interface mentioned above, or a different type of interface; for example, the first interface could be a USB interface, and the second interface could be an I2C interface.

[0208] Through the embodiment shown in Figure 5, the TPIC can use either a first mode or a second mode. Regardless of which mode is used, it can switch to another mode when certain conditions are met. For example, please refer to Figure 7, which is a flowchart illustrating a touch method provided in an embodiment of this application. This method can be applied to a display system, such as the structure shown in Figure 4A. The display system can be installed in an electronic device, such as a laptop or tablet computer. As shown in Figure 7, the process includes:

[0209] S701, TPIC uses the first mode. The first mode is the mode that uses the first driver to communicate with the SOC. Please refer to the previous text for details.

[0210] S702, when TPIC determines that the first condition is met, it can switch from the first mode to the second mode.

[0211] In some embodiments, TPIC can determine whether the first condition is met based on system status information. For information on system status information and how TPIC obtains it, please refer to the preceding text; it will not be repeated here.

[0212] Optionally, the first condition may include at least one of the following:

[0213] (1) First driver anomaly. Optionally, first driver anomaly may include: the first driver being deleted, uninstalled, disabled, or invaded by a virus.

[0214] (2) The current system enters the second system. The second system is a system other than the first system. For example, the first system is the main operating system, such as the Windows system, and the second system is the pre-operating system, such as the Pre system; or, the first system is the host system and the second system is the client system.

[0215] (3) The SOC is currently running the second preset application. The second preset application is an application other than the first preset application mentioned above. For information about the first preset application, please refer to the previous description.

[0216] (4) The current operating load of the SOC is greater than the first preset load. As mentioned above, in the first mode, the computing power is borne by the SOC, and in the second mode, the computing power is borne by the TPIC. Therefore, when the SOC load is large, the second mode can be used to reduce the burden on the SOC, and when the SOC load is small, the first mode can be used to reduce the burden on the TPIC.

[0217] (5) A user operation is received, which is used to switch from the first mode to the second mode. As an example, before receiving the user operation, the electronic device may output a prompt message to indicate whether to enter the second mode. The electronic device enters the second mode after receiving the confirmation operation.

[0218] (6) The current operating load of the TPIC is less than the second preset load. As mentioned above, in the first mode, the computing power is borne by the SOC, and in the second mode, the computing power is borne by the TPIC. Therefore, when the TPIC load is large, the first mode can be used to reduce the burden on the TPIC, and when the TPIC load is small, the second mode can be used to reduce the burden on the SOC.

[0219] S703, TPIC uses the second mode.

[0220] In some embodiments, after the electronic device switches to the second mode, it may also output a prompt message to indicate that the electronic device has entered the second mode.

[0221] S704, when TPIC determines that the second condition is met, it can switch from the second mode to the first mode.

[0222] In some embodiments, TPIC can determine whether the second condition is met based on system status information. For information on system status information and how TPIC obtains it, please refer to the preceding text; it will not be repeated here.

[0223] Optionally, the second condition may include at least one of the following:

[0224] (1) The first drive has returned to normal.

[0225] (2) The current system enters the first system.

[0226] (3) The SOC is currently running the first preset application.

[0227] (4) The current operating load of the SOC is less than or equal to the first preset load.

[0228] (5) A user operation is received, which is used to switch from the second mode to the first mode. As an example, before receiving the user operation, the electronic device may output a prompt message to indicate whether to enter the first mode. The electronic device enters the first mode after receiving the confirmation operation.

[0229] (6) The current running load of TPIC is greater than or equal to the second preset load.

[0230] (7) The second driver is abnormal.

[0231] In some embodiments, after the electronic device switches to the first mode, it may also output a prompt message to indicate that the electronic device has entered the first mode.

[0232] Figure 8 is a schematic diagram of an electronic device provided in an embodiment of this application. This figure can be understood as a schematic diagram of the software system of the electronic device. As shown in Figure 8, the software system of the electronic device can adopt a layered architecture, which divides the software into several layers, each with a clear role and division of labor. The layers communicate with each other through software interfaces. Of course, in addition to the layered architecture, event-driven architecture, microkernel architecture, microservice architecture, or cloud architecture can also be adopted, etc., which are not limited in this embodiment. This embodiment mainly uses a layered architecture as an example for explanation. As shown in Figure 8, the software system of the electronic device can include four layers, from top to bottom: application layer, service layer, driver layer, and hardware layer. It should be noted that Figure 8 uses a software system with four layers as an example. In actual products, there may be more or fewer layers than in Figure 8, and the name of each layer, the positional relationship between layers, etc., are not limited in this embodiment.

[0233] As shown in Figure 8, the application layer includes various types of applications, such as the first application. The first application can be an application with a writing scenario, such as a note-taking application (e.g., a memo), a drawing application, a meeting application, etc. Of course, the first application can also be other applications, which are not limited in the embodiments of this application.

[0234] As shown in Figure 8, the service layer includes HID service and THP service. HID service connects the first application in the application layer with the HID driver in the driver layer. For example, HID service can send the location coordinates provided by the HID driver to the first application for a response. THP service connects to the THP driver in the driver layer and calculates the location coordinates based on the capacitance data reported by the THP driver. It should be noted that THP service needs to provide the calculated location coordinates to the first application for a response. The communication methods between THP service and the first application can include several types. Method A: THP service connects directly to the first application and directly sends the calculated location coordinates to the first application. Method B: THP service connects to the first application through HID service. For example, THP service sends the calculated location coordinates to HID service, which then sends the location coordinates to the first application. One possible scenario for Method B is that the electronic device is pre-configured with HID service at the factory, and the first application only recognizes the location coordinates transmitted by HID service (where "recognize" can be understood as responding to the location coordinates). If THP service directly sends the location coordinates to the first application, the first application may treat it as unfamiliar information and delete it. Therefore, the THP service needs to send the location coordinates to the HID service, which then forwards them to the first application. As mentioned earlier, in method B, the THP service needs to send the calculated location coordinates to the HID service. Optionally, the THP service sending the location coordinates to the HID service can include: the THP service is directly connected to the HID service and directly sends the location coordinates to the HID service. Alternatively, there is a possibility that the HID service recognizes the location coordinates sent by the HID driver in the driver layer, and the THP service directly sending the location coordinates to the HID service might be treated as unfamiliar information and deleted. Therefore, the electronic device can create a virtual HID. Since the virtual HID is a simulation of the HID driver, the HID service will recognize the location coordinates sent by the virtual HID. Therefore, the THP service can send the location coordinates to the virtual HID, which then sends them to the HID service, so that the HID service can send the location coordinates to the first application.

[0235] As shown in Figure 8, the driver layer includes the HID driver, the virtual HID driver, and the THP driver. The HID driver and THP driver are described previously and will not be repeated here. The virtual HID driver can be understood as a virtual unit of the HID driver, which can connect the THP service and the HID driver. For example, it can provide the location coordinates sent by the THP service to the HID service, so that the HID service can send the location coordinates to the first application for a response.

[0236] As shown in Figure 8, the hardware layer includes a touch display screen. The touch display screen includes a touch panel and a TPIC, as described above, and will not be repeated here.

[0237] The following text continues with Figure 8 as an example to illustrate the dual-drive touch method provided in the embodiments of this application.

[0238] As an example, please refer to Figure 9, which is a flowchart of a touch method provided in an embodiment of this application. This figure can be understood as an information interaction diagram between various modules in the software system shown in Figure 8. As shown in Figure 9, the process may include:

[0239] (1) The TPIC in the touchscreen determines whether to use a first mode (e.g., THP mode) or a second mode (e.g., TPP mode). For example, the TPIC can obtain system status information and determine whether to use the first mode or the second mode based on the system status information. Please refer to the preceding text for information on system status information and the process of determining which mode to use based on the system status information; it will not be repeated here. One possible implementation is as shown in Figure 9, where the TPIC (not shown in Figure 9) can connect to the THP driver through a third interface to obtain system status information from the THP driver through the third interface. For example, the third interface can be a GPIO interface. As an example, the THP driver can obtain system status information from the THP service. Optionally, the THP service can collect system status information itself or from applications and / or functions in the electronic device used to collect system status information. For example, the application and / or function can be called a monitoring application, which is not shown in Figure 9.

[0240] If TPIC determines to use the first mode, the first path in Figure 9 can be used, which is represented by ①. If it determines to use the second mode, the second path in Figure 9 can be used, which is represented by ②.

[0241] (2) In the first mode, the information transmission process using the first path may include: (2.1) TPIC sends first information to the THP driver, the first information including first capacitor data. (2.2) The THP driver sends the first capacitor data to the THP service. (2.3) The THP service calculates the first location coordinates based on the first capacitor data and sends the first location coordinates to the virtual HID driver. (2.4) The virtual HID driver sends the first location coordinates to the HID service. (2.5) The HID service sends the first location coordinates to the first application so that the first application can respond to the first location coordinates.

[0242] (3) In the second mode, the information transmission process using the second path may include: (3.1) TPIC sends second information to the HID driver, the second information including second location coordinates, which are calculated by TPIC based on the second capacitance data. (3.2) The HID driver sends the second location coordinates to the HID service. (3.3) The HID service sends the second location coordinates to the first application so that the first application can respond to the second location coordinates.

[0243] As mentioned above, when a user operates on the touch screen of an electronic device using a stylus, the stylus can sense at least one of the following: pressure data, angle data, acceleration data, etc. The stylus can transmit at least one of the following data to the SOC of the electronic device via Bluetooth.

[0244] For example, please refer to Figure 10, which is another flowchart illustrating a touch method provided in an embodiment of this application. The difference between Figure 10 and Figure 9 is that Figure 10 is applicable to stylus interaction scenarios, where the stylus sends other data, such as pressure data, angle data, acceleration data, etc., to the THP service via Bluetooth. One possible approach is that if the TPIC determines to use the first mode, the first path and the third path in Figure 10 can be used, where the first path is represented by ① and the third path by ③; the third path is used to transmit pressure data, angle data, acceleration data, etc., via Bluetooth. If the second mode is determined to be used, the second path in Figure 10 can be used, where the second path is represented by ②.

[0262] In this embodiment, the display screen 194 may be a touch display screen. The touch display screen includes a touch panel and a TPIC, which are described above. The TPIC supports two modes: a first mode and a second mode. In the first mode, the TPIC communicates with the processor 110 based on a first driver (e.g., a THP driver). In the second mode, the TPIC communicates with the processor 110 based on a second driver (e.g., a HID driver). Taking the first mode as an example, after the TPIC collects the first capacitance data, it sends the first information to the processor 110. The first information is based on a first driver protocol (e.g., a THP protocol) and includes the first capacitance data. The processor 110 determines the first position coordinates based on the first capacitance data and responds based on the first position coordinates (e.g., updating the interface). In the first mode, the TPIC does not need to perform the calculation process from capacitance data to position coordinates, reducing computational power. When the electronic device meets a first condition (e.g., a first driver malfunction), it switches from the first mode to the second mode. After switching to the second mode, the TPIC collects the second capacitance data and obtains the second position coordinates based on the second capacitance data. The TPIC sends second information to the processor 110, which is based on a second driving protocol (e.g., HID protocol) and includes second position coordinates. The processor 110 responds based on these second position coordinates (e.g., updating the interface). In this second mode, the TPIC handles the calculation of the capacitance data to position coordinates, eliminating the need for the processor 110 to calculate the coordinates, thus enabling a faster response.
