[0033] The information display device is a device that can be independent of the movable device and can be installed on the movable device or placed in a fixed position according to the actual application scenario.

[0034] The trigger unit can be set outside the information display equipment, and the user can directly send a trigger signal through the trigger unit. The form of the trigger unit is not limited, and it can be an electronic button, a mechanical button, a touch screen, a signal receiving device, etc. Correspondingly, the interaction method with the trigger unit varies depending on the form of the trigger unit and the specific settings.

[0035] The information processing module is connected to the trigger unit. The information processing module can be a microcontroller unit (MCU). When the trigger unit generates a trigger signal, the information processing module is awakened and generates configuration information according to the trigger signal. The configuration information includes at least the name of the target application and the name of the information to be displayed. There is a corresponding relationship between the trigger signal and the name of the target application and the name of the information to be displayed. The corresponding relationship can be determined by presetting the information display device, and can be configured by the software application corresponding to the information display device. The target application is an application installed in a removable device, and the information to be displayed can be obtained from the target application. The target application name can correspond to multiple names of information to be displayed, so the trigger signal specifically corresponds to the name of the information to be displayed. Taking the target application as a payment application as an example, the target application name is A, and the name of the information to be displayed may include a payment code, a receipt code, etc. In addition, the configuration information may also include device information of the information display device, such as a device identification number.

[0036] The wireless communication module can be used to communicate with the mobile device to transmit data.

The corresponding relationship in the configuration file can be set in advance according to actual needs, for example, by setting it in the corresponding software application, so that the configuration file is stored in the configuration module.

[0041] When a trigger signal is generated, the configuration module in the information processing module determines the name of the information to be displayed in the configuration file according to the trigger signal, wherein the name of the target application corresponding to the name of the information to be displayed is also set. Different trigger signals correspond to different names of information to be displayed. For example, if the target application is a payment software and the button is a mechanical button, the name of the information to be displayed corresponding to a single click of the button is a payment code, and the name of the information to be displayed corresponding to a double click of the button is a receipt code.

[0042] In some optional implementations, the information to be displayed is generated according to the target application name and the name of the information to be displayed in the configuration information.

[0043] Configuration information is generated according to the name of the information to be displayed and the name of the target application. The configuration information may also include an identifier of the information display device. The removable device may verify the information display device according to the identifier to ensure security.

[0044] In some optional implementations, the wireless communication module uses at least one of NFC (Near Field Communication), RFID (Radio Frequency Identification), Bluetooth, and 2.4 GHz wireless communication technologies.

[0050] In this embodiment, an information display method is provided, which is applied to an information display device. Figure 2 is a flow chart of an information display method according to an embodiment of the present invention. Figure 2 As shown, the process includes the following steps:

[0051] Step S201, receiving a trigger signal.

[0052] Specifically, the information display device receives a trigger signal.

[0053] The trigger unit is arranged outside the information display device, and the user can send a trigger signal through the trigger unit, so that the information display device receives the trigger signal.

[0054] Step S202, determining configuration information.

[0055] Specifically, the information display device determines configuration information in response to a trigger signal, and the configuration information at least includes a target application name and a name of information to be displayed.

[0056] When the trigger unit generates a trigger signal, the information processing module is awakened and generates configuration information according to the trigger signal. The configuration information includes at least the name of the target application and the name of the information to be displayed. There is a corresponding relationship between the trigger signal and the name of the target application and the name of the information to be displayed. The corresponding relationship can be determined by configuring the information display device, and can be specifically configured by the software application corresponding to the information display device.

[0064] In some optional implementations, the mobile device determines the target application according to the target application name in the configuration information, and determines the information to be displayed according to the name of the information to be displayed.

[0065] After receiving the configuration information, the mobile device can verify the information display device based on the information about the information display device in the configuration information. After the verification is passed, the target application can be determined based on the target application name in the configuration information, and then the target application can be called through the operating system. The target application generates information to be displayed and sends the information to be displayed to the information display device through the second communication link.

[0066] Step S205: display the information to be displayed.

[0067] Specifically, it includes an information display device that displays information to be displayed.

[0068] After receiving the information to be displayed, the information display device can display the information to be displayed through the display module. The information display method provided in this embodiment receives a trigger signal, and in response to the trigger signal, determines configuration information, wherein the configuration information at least includes the name of the target application and the name of the item information to be displayed; transmits the configuration information to the removable device through a first communication link; receives the information to be displayed sent by the removable device through a second communication link; and displays the information to be displayed. This method can control the information display device to display the information to be displayed by operating the trigger unit of the information display device without opening the main screen of the removable device or affecting the main screen and button operation of the removable device, thereby improving the performance of the display function of the information display device and ensuring the user experience.

[0069] Optionally, the wireless charging module in the information display device can be an energy storage capacitor, which can obtain energy from a removable device or other external device for the information display device to perform its functions. Optionally, the wireless charging module and the wireless communication module can share a set of NFC devices. In passive mode, the screen is refreshed through NFC field induction energy, so that when the battery of the information display device is exhausted, the system can continue to work in passive mode.

[0070] In this embodiment, an information display method is provided by taking the information display device as a mobile phone case and the mobile device as a mobile phone as an example. The mobile phone case can be an ultra-low power consumption electronic mobile phone back cover, which is installed on the back of the mobile phone. The mobile phone case is provided with a trigger unit, an information processing module, a wireless communication module and a display module. The method is specifically as follows:

[0071] Step S301, receiving a trigger signal;

[0072] The trigger unit may be a button set on the surface of the mobile phone case, and may specifically be one of a button, a touch screen, and a signal receiving device. The interaction method with the trigger unit varies depending on the form and specific settings of the trigger unit. When the trigger unit is a button, a trigger signal may be sent through the button, which may specifically include tapping, long pressing, double-clicking, etc. When the trigger unit is a touch screen, a trigger signal may be sent through sliding, tapping with one finger, tapping with two fingers, etc. The signal receiving device may send a trigger signal by receiving different signals. The user may send a trigger signal through the trigger unit, so that the mobile phone case receives the trigger signal.

[0073] Step S302, determining configuration information;

[0074] The information processing module is connected to the trigger unit, and the information processing module can be specifically an MCU. When the trigger unit generates a trigger signal, the information processing module is awakened and generates configuration information according to the trigger signal. The configuration information at least includes the name of the target application and the name of the information to be displayed. There is a corresponding relationship between the trigger signal and the name of the target application and the name of the information to be displayed. The corresponding relationship can be determined by configuring the information display device, and can be specifically configured by a software application corresponding to the information display device. The target application is an application installed in the mobile phone, and the information to be displayed can be obtained from the target application.

[0075] The configuration information generated by the information processing module according to the trigger signal at least includes the name of the target application program and the name of the information to be displayed.

[0076] Step S303: Transmit configuration information.

[0077] The mobile phone case is equipped with a wireless communication module, which can be used to communicate with the mobile phone. The wireless communication module can be an NFC device, a Bluetooth device, etc. The NFC device includes an NFC chip and an NFC antenna. The NFC antenna is a coil designed to match the NFC chip. Data communication is performed with the mobile phone through the wireless communication module, and configuration information is sent to the mobile phone.

[0078] For example, when the wireless communication module is an NFC device, when configuration information is generated, the NFC device is called to open by the information processing module, and correspondingly, the mobile phone is also equipped with an NFC device that communicates with the NFC device on the mobile phone case. The configuration information is sent to the mobile phone via NFC.

[0079] Step S304, receiving information to be displayed.

[0080] After receiving the information to be displayed, the mobile phone verifies the mobile phone case according to the information about the information display device in the configuration information. After the verification is passed, the target application can be determined according to the target application name in the configuration information, and then the target application is called through the mobile phone system. The target application generates the information to be displayed and packages the information to be displayed, and sends the information to be displayed to the information display device through the second communication link. The second communication link and the first communication link can be the same.

[0081] Taking the target application name as payment software A and the name of the information to be displayed as the payment code as an example, the mobile phone calls the payment software A through the operating system according to the target application name, calls the payment code through the payment software A, and obtains the payment code image as the information to be displayed.

[0082] Step S305: display the information to be displayed.

[0083] After the mobile phone case receives the information to be displayed through the wireless communication module, it transmits the information to be displayed to the MCU through the interface, and the MCU controls the display device to quickly refresh and display the information to be displayed.

[0084] The information display method provided in this embodiment is applied to a mobile phone case, receives a trigger signal through a trigger unit on the mobile phone case, determines configuration information in response to the trigger signal, transmits the configuration information to the mobile phone through a first communication link, and receives information to be displayed sent by the mobile phone through a second communication link, and displays the information to be displayed. This method can control the mobile phone case to display the information to be displayed in the target application by operating the trigger unit on the mobile phone case without opening the mobile phone main screen or affecting the mobile phone main screen and key operations, thereby improving the performance of the mobile phone case display function.

[0085] In this embodiment, a method for displaying information is provided, which involves mobile phone side software and a secondary screen mobile phone case. The secondary screen mobile phone case components include: an EPD display module, a button, an MCU, NFC, an NFC antenna, a battery, and an energy storage capacitor. The button is a trigger unit, which is installed on the surface of the mobile phone case. It can be a mechanical button or an electronic button, which is used to wake up the MCU. The button function can be set through the configuration application for the user to call the content options to be displayed quickly. The MCU is the main controller (information processing module) of the secondary screen mobile phone case, which is used to handle the control and communication of the entire mobile phone case. The wireless communication module in this embodiment is an NFC device, including an NFC chip and an NFC antenna. The NFC antenna is an NFC coil designed to match the NFC chip. The battery is used to power the entire mobile phone case including the display module. The energy storage capacitor is optional. In passive mode, the screen is refreshed through the NFC field induction energy. When the battery of the mobile phone case is exhausted, the system can continue to work in passive mode. The target application, configuration application, etc., and the second wireless communication module are installed on the mobile phone side, corresponding to the wireless communication module. The second wireless communication module in this embodiment is an NFC device. The configuration application can initialize the mobile phone case and set the function of the button to support picture refresh. There is no restriction on the mobile phone system, which can be IOS, Android and its variants from various mobile phone manufacturers, Hongmeng and other mainstream OS.

[0086] First, you can configure the function combination of the sub-screen buttons and display related specification parameter information through the configuration application according to your needs, such as the time and color information when fast swiping. When in use, after the user presses the button, the MCU is awakened from the deep sleep state and is in the running state. The MCU controls the NFC opening and transmits a message to the mobile phone system NFC to notify the system of the information to be displayed, including the target application and the specific content to be displayed. The NFC on the mobile phone reads the NFCtag data, and after receiving the information to be quickly displayed on the sub-screen, it calls the corresponding App. After the target application receives the system call signal, it generates the information to be displayed, packages the information to be displayed, calls the NFC permission on the mobile phone side, and transmits the information to be displayed (text, QR code, picture) to the mobile phone sub-screen NFC through NFC. The sub-screen NFC receives the information to be displayed and passes it to the MCU through the interface. The MCU controls the display module to quickly refresh and display. After the fast swiping is completed, the business completion message is pushed to the mobile phone system and the configuration App for log management through the link.

[0087] In some optional implementations, the wireless communication module and the second wireless communication module in the above method may be Bluetooth devices, and the display module may be a liquid crystal display module.

[0088] When the information display method provided in this embodiment is applied to a mobile phone case, it supports active operation by the user. The user can activate the built-in circuit and processor of the mobile phone case at any time through the buttons integrated on the mobile phone case. After the internal processor of the mobile phone back shell is activated, the communication function (NFC, Bluetooth, etc.) integrated in the mobile phone back shell is used to activate the built-in application of the mobile phone, and the message is transmitted to the mobile phone. The mobile phone decides which App to open based on the message pushed by the back shell, and transmits the message to the App. The App calls the built-in communication function of the mobile phone, such as NFC or Bluetooth, to push the message to the display module on the back shell of the mobile phone; after receiving the display information, the display module on the back shell determines whether to perform a quick refresh; if it is specific information such as a QR code, the quick refresh program is immediately started, and the information is displayed on the secondary screen of the mobile phone back shell within 1 to 5 seconds. This method supports the active display of information of multiple different Apps on the secondary screen. This method can be operated without the main screen of the mobile phone, is suitable for the lock screen state of the mobile phone, can quickly realize the content display of the secondary screen, and supports background data production and push, without the need for foreground operation and push.

[0089] In this embodiment, an information display method is provided, which is applied to a mobile device. The mobile device can be a terminal such as a mobile phone or a tablet computer. The mobile device is equipped with a second wireless communication module, which corresponds to the wireless communication module in the information display device and can be used to communicate data with the information display device. The operating system of the mobile device includes but is not limited to IOS, Android, Hongmeng, etc. The mobile device is equipped with a target application. Figure 3 The method provided in this embodiment includes the following steps:

[0090] Step S401: receiving configuration information sent by the information display device based on the second wireless communication module.

[0091] The configuration information at least includes the name of the target application and the name of the information to be displayed, and the second wireless communication module is used to communicate with the wireless communication module on the information display device.

Communication is performed with the wireless communication module on the information display device based on a second wireless communication module. The second wireless communication module is consistent with the wireless communication module, and may be an NFC device, a Bluetooth device, etc.

[0093] When the user needs to display the information to be displayed in the target application on the information display device, the trigger signal is generated by operating the trigger unit to wake up the information processing module (e.g. MCU) in the information display device, and then determine the name of the target application corresponding to the trigger signal and the name of the information to be displayed. Among them, the information processing module can be used to handle the control and communication of the entire information display device. The information to be displayed can be data in the form of pictures, texts, etc.

[0094] Step S402: calling the target application based on the configuration information to obtain information to be displayed from the target application.

[0095] After receiving the configuration information, a target application is determined therefrom, and the target application is called through the operating system control, thereby extracting information to be displayed from the target application. The information to be displayed may be in the form of pictures, texts, and the like.

[0096] Step S403: sending the information to be displayed to the information display device based on the second wireless communication module, so that the information display device displays the information to be displayed.
