Mobile device display case and control method, system, and storage medium

Abstract

The application relates to a mobile device display shell and a control method and system thereof and a storage medium. The mobile device display shell receives instructions from a mobile device through an instruction receiving module. Then, whether the working state of a first radio frequency unit of the mobile device display shell needs to be started is judged according to the instruction type. When a first preset instruction is received, the working state of the first radio frequency unit of the mobile device display shell is triggered to start, and target image data transmitted from a second radio frequency unit of the mobile device is received through the radio frequency unit. Finally, a display screen displays the received target image. In this way, the NFC function of the mobile device display shell is activated only when the image needs to be refreshed, thereby avoiding the simultaneous work of the mobile device NFC function in unnecessary cases and effectively reducing the possibility of radio frequency interference.

[0024] With the continuous development of smart mobile device technology, NFC (Near Field Communication) technology is increasingly widely used in daily life, such as access card simulation, payment, and data transmission. In recent years, NFC e-ink screen phone cases, as an innovative product combining NFC technology and e-ink display technology, have received widespread attention from consumers. These phone cases not only provide personalized information display functions but also interact with the phone via NFC technology, enabling various application scenarios such as data transmission and quick operations. However, existing NFC e-ink screen phone cases face a significant problem in practical applications: radio frequency interference may occur between the NFC function of the phone case and the NFC function of the phone itself, leading to functional conflicts or malfunctions. For example, when the phone is used as an access card, the NFC radio frequency of the phone case may interfere with the phone's normal NFC communication, causing the access control system to fail to recognize it; similarly, when the phone is used as an NFC card reader to read other cards or tags, the NFC radio frequency of the phone case may also cause reading failures or identification errors. These problems severely limit the practicality and user experience of NFC e-ink screen phone cases.

[0025] In response, this application provides a mobile device display case and its control method, system, and storage medium, which effectively avoids radio frequency interference between the phone case and the phone's NFC function, ensuring that both can operate normally in their respective working scenarios.

[0026] Please refer to Figure 1 The first aspect of this application provides a control method for a mobile device display shell, the mobile device display shell including a first radio frequency unit, an instruction receiving module, and a display screen; the first radio frequency unit is connected to the instruction receiving module, and the first radio frequency unit is connected to the display screen; the method includes the following steps:

[0027] S101: Receive instructions sent by the mobile device through the instruction receiving module;

[0028] S102: When the instruction is a first preset instruction, the first radio frequency unit is triggered to start working.

[0029] S103: Receive the target image sent by the second radio frequency unit of the mobile device through the first radio frequency unit, and control the display screen to display the target image.

[0030] The mobile device display case in this embodiment receives instructions from the mobile device via an instruction receiving module. Then, it determines whether the first radio frequency unit of the mobile device display case needs to be activated based on the instruction type. When a first preset instruction is received, the first radio frequency unit of the mobile device display case is triggered to activate, and target image data sent from the second radio frequency unit of the mobile device is received through this radio frequency unit. Finally, the display screen is controlled to display the received target image. In this way, the NFC function of the mobile device display case is only activated when image refresh is required, thereby avoiding simultaneous operation with the NFC function of the mobile device under unnecessary circumstances and effectively reducing the possibility of radio frequency interference. The mobile device display case control method of this embodiment can significantly improve the practicality and user experience of existing NFC e-ink screen phone cases, avoiding functional conflicts or malfunctions caused by mutual interference. Furthermore, it has advantages such as ease of implementation and good compatibility, and is suitable for various brands and models of smartphones, with broad application prospects.

[0031] The control method for the mobile device display case in this embodiment is executed by the mobile device display case itself. The mobile device display case can be an NFC e-ink screen phone case or other phone cases employing similar display principles. The following provides a detailed description of each step.

[0032] For step S101, the instruction received by the instruction receiving module is received from the instruction sent by the mobile device.

[0033] A connection is established between the mobile device and its display shell via wireless transmission. When a user performs a specific operation on the mobile device, the device generates a corresponding command and transmits it wirelessly to the command receiving module on the display shell. The command receiving module is a dedicated component for receiving and processing commands from the mobile device; it accurately receives and identifies the content of the commands sent by the mobile device.

[0034] For example, when a user wants to refresh a specific image on the phone case's display, they might select the corresponding application or function on the mobile device, triggering a command generation process. This command is then wirelessly transmitted from the mobile device to the command receiving module of the mobile device's display case.

[0035] In one embodiment, the mobile device wirelessly transmits data between its command sending module and the command receiving module of its display casing. The command sending module and command receiving module are a pair of corresponding components with clearly defined functions. The command sending module is primarily responsible for sending information, while the core function of the command receiving module is to detect information, thereby facilitating information transfer between the mobile device and its display casing. The command sending and receiving modules can be selected based on different information transmission principles. In one embodiment, based on vibration detection, the command sending module can be a motor, and the command receiving module can be a vibration sensor. In another embodiment, based on electromagnetic induction, both the command sending and receiving modules can be electromagnets. In yet another embodiment, based on optical sensing, the command sending module can be a light emitting device such as an LED, and the command receiving module can be a light sensor.

[0036] For step S102, when the instruction is a first preset instruction, the first radio frequency unit is triggered to start working.

[0037] Upon receiving an instruction from the mobile device, the instruction receiving module parses and identifies the instruction. If the instruction content matches a preset first instruction, the first radio frequency unit within the mobile device's display casing is activated. The first radio frequency unit is a core component within the mobile device's display casing used for NFC communication; it can transmit data with the mobile device's second radio frequency unit (i.e., the NFC module) at close range. In this embodiment, after the first radio frequency unit is activated, it enters a standby state, ready to receive data from the mobile device's second radio frequency unit.

[0038] It's important to note that the first preset command is pre-set in the mobile device's display shell control system. It represents the command the mobile device's display shell needs to perform a specific function (such as displaying an image). In practical applications, users can customize the content of the first preset command as needed to better meet their individual requirements.

[0039] In one embodiment, after step S101, which involves receiving instructions sent by the mobile device through the instruction receiving module, the method further includes the following step:

[0040] Step S1011: When the instruction is a second preset instruction, the first radio frequency unit is triggered to enter a sleep state so that the first radio frequency unit does not respond to radio frequency signals.

[0041] In step S101, after the instruction receiving module successfully receives the instruction sent by the mobile device, it determines whether the instruction is a first preset instruction or a second preset instruction. If the received instruction matches the second preset instruction, the first radio frequency unit is triggered to enter a sleep state. In the sleep state, the first radio frequency unit will stop responding to any radio frequency signals, thereby avoiding unnecessary energy consumption and potential radio frequency interference. Similarly, the second preset instruction is another specific instruction preset in the mobile device display shell control system, which represents that the mobile device display shell needs to enter a low-power state or stop performing specific functions.

[0042] This embodiment makes the mobile device display case control method more flexible and efficient. Users can control the NFC function of the mobile device display case by sending different commands according to actual needs, achieving a more personalized user experience. At the same time, by allowing the first radio frequency unit to enter a sleep state when not needed, radio frequency interference to the mobile device can be effectively reduced, and the overall energy efficiency of the device can be improved.

[0043] In one embodiment, the mobile device display casing further includes a storage module and a radio frequency unit control module, wherein the first radio frequency unit and the instruction receiving module are respectively connected to the storage module; the radio frequency unit control module is connected to the first radio frequency unit; and the instruction receiving module acquires the instruction sent by the mobile device and stores the instruction in the storage module.

[0044] Step S102, which involves triggering the first radio frequency unit to start its working state when the instruction is a first preset instruction, includes:

[0045] The radio frequency unit control module reads the instructions stored in the storage module, and when the instruction is a first preset instruction, it controls the first radio frequency unit to start working.

[0046] Step S1011, which involves triggering the first radio frequency unit to enter a sleep state when the instruction is a second preset instruction, includes:

[0047] The radio frequency unit control module reads the instructions stored in the storage module. When the instruction is a second preset instruction, the first radio frequency unit is controlled to enter a sleep state.

[0048] The storage module stores instructions sent by the mobile device. The storage module can be any type of storage device, such as flash memory, hard disk, or other non-volatile storage devices. In this embodiment, the storage module receives instructions from the instruction receiving module and saves them for subsequent processing.

[0049] The radio frequency (RF) unit control module is used to control the operating state of the first RF unit. The RF unit control module can be a microprocessor, microcontroller, or other device capable of executing control logic. It receives instructions from the storage module and controls the first RF unit to start, sleep, or other states according to the instructions.

[0050] After introducing the storage module and the radio frequency unit control module, the mobile device display shell control method in this embodiment has been adjusted as follows: When the instruction receiving module receives an instruction sent by the mobile device, it no longer processes the instruction directly, but stores it in the storage module. When processing the first preset instruction and the second preset instruction, the radio frequency unit control module first reads the instruction from the storage module, and then executes the corresponding control logic according to the instruction content. If the instruction is the first preset instruction, the radio frequency unit control module will control the first radio frequency unit to start working; if the instruction is the second preset instruction, the radio frequency unit control module will control the first radio frequency unit to enter sleep mode.

[0051] In summary, this embodiment improves system stability and reliability by introducing a storage module and an RF unit control module. The storage module ensures the integrity and security of instructions; even if an interruption or error occurs during processing, the instructions can still be recovered and reprocessed. This reduces the system failure rate caused by lost or corrupted instructions.

[0052] In step S103, the first radio frequency unit receives the target image sent by the second radio frequency unit of the mobile device and controls the display screen to display the target image.

[0053] After the first radio frequency unit starts operating, the second radio frequency unit of the mobile device acts as the data transmitter, sending the target image data to be displayed to the first radio frequency unit of the mobile device's display casing. This data includes pixel information, color information, and other essential elements necessary for a complete image. Upon receiving this data, the first radio frequency unit decodes and processes it, then sends the processed data to the display control system. The display control system is a dedicated component for controlling the content displayed on the screen. It generates corresponding display signals based on the received data and drives the screen to display the image. Ultimately, under the control of the display control system, the screen accurately displays the received target image. This allows the user to see content on the mobile device's display casing that is completely identical to the image sent by the mobile device.

[0054] Please refer to Figure 2The second aspect of this application provides a display control method for a mobile device casing, applied to a mobile device. The mobile device includes an instruction sending module, a second radio frequency unit, and a control module, wherein the instruction sending module and the second radio frequency unit are respectively connected to the control module. The method includes the following steps:

[0055] S201: The control module generates a first preset instruction and controls the instruction sending module to send the first preset instruction to the instruction receiving module of the mobile device shell to trigger the first radio frequency unit in the mobile device display shell to start working.

[0056] S202: The control module acquires the target image and controls the first radio frequency unit to send the target image to the second radio frequency unit of the mobile device casing, so that the display screen of the mobile device casing displays the target image.

[0057] The display control method for the mobile device shell in this embodiment belongs to the same technical concept as the method in the above embodiment. The main difference is that this embodiment is written and protected from the mobile device side. In addition, further limitations can be added for the mobile device side, as detailed in the following description.

[0058] In this embodiment, the mobile device mainly includes the following modules: a command sending module, responsible for sending control commands from the mobile device to the mobile device display shell; a second radio frequency unit, referring to the NFC module built into the mobile device, used for data transmission with the first radio frequency unit in the mobile device display shell; and a control module, as the core control unit of the mobile device, responsible for generating control commands, managing data transmission, and coordinating the collaborative work between the modules.

[0059] In step S201, when a user desires to display specific content (such as images, information prompts, etc.) on the mobile device's display shell, the application or user interface on the mobile device triggers the control module to generate a first preset command. This command is a specific signal or code used to instruct the mobile device's display shell to activate its NFC communication function. After generating the first preset command, the control module sends it to the command sending module. The command sending module then wirelessly transmits the command to the command receiving module of the mobile device's display shell. This step is crucial for initiating the entire display control process.

[0060] In step S202, after sending the first preset command, the control module further acquires the target image from the mobile device's storage unit, camera, or other image source. These images can be user-selected photos, application-generated graphics, or text information, etc. After acquiring the target image, the control module sends it to the first radio frequency unit of the mobile device's display casing via the second radio frequency unit. Upon receiving the target image, the mobile device's display casing displays it on its screen.

[0061] In summary, the display control method for the mobile device casing in this embodiment achieves seamless connection and data transmission with the mobile device display casing through the coordinated operation of the instruction sending module, the second radio frequency unit, and the control module on the mobile device side. This method not only simplifies user operation and improves system usability, but also fully utilizes the advantages of NFC or other near-field communication technologies to achieve fast and secure data exchange and display control.

[0062] In one embodiment, the method further includes the step of:

[0063] Step S203: The control module generates a second preset instruction and controls the instruction sending module to send the second preset instruction to the instruction receiving module of the mobile device shell, so as to trigger the first radio frequency unit in the display shell of the mobile device to enter a sleep state.

[0064] In this embodiment, when the user wants the mobile device display case to stop working and enter a low-power state, the application or user interface on the mobile device triggers the control module to generate a second preset instruction. This instruction is a specific signal or code used to instruct the mobile device display case to disable its NFC communication function and enter a sleep state. After the control module generates the second preset instruction, it sends it to the instruction receiving module of the mobile device display case through the instruction sending module, thereby triggering the key for the mobile device display case to enter a sleep state.

[0065] In one embodiment, the mobile device is equipped with a control program;

[0066] When the control program starts, the control module generates a first preset instruction and controls the instruction sending module to send the first preset instruction to the instruction receiving module of the mobile device shell;

[0067] When the control program is closed, the control module generates a second preset instruction and controls the instruction sending module to send the second preset instruction to the instruction receiving module of the mobile device shell.

[0068] In this embodiment, the mobile device also carries a dedicated control program for automatically generating and sending control commands. The generation and sending of control commands are achieved by starting and stopping the control program.

[0069] When a user launches the control program on their mobile device, the program triggers the control module to generate a first preset command. The control module then sends the first preset command to the command sending module, which in turn wirelessly transmits the command to the command receiving module of the mobile device's display casing. Upon receiving the first preset command, the mobile device's display casing activates its NFC communication function, preparing to receive and display the target image from the mobile device. When the user closes the control program on their mobile device, the program triggers the control module to generate a second preset command. The control module then sends the second preset command to the command sending module, which in turn wirelessly transmits the command to the command receiving module of the mobile device's display casing. Upon receiving the second preset command, the mobile device's display casing disables its NFC communication function and enters a low-power sleep state.

[0070] The display control method for the mobile device casing in this embodiment further simplifies user operation and improves the system's intelligence and user experience through automated control based on the start and stop of the control program.

[0071] In one embodiment, before step S202, which involves acquiring the target image through the control module, the following steps are included:

[0072] Step S2021: The control program acquires the image selected by the user and uses the image as the target image.

[0073] In this embodiment, when the control program runs, a user interface can be displayed on the mobile device's screen, allowing users to browse, select, and edit images. Users can browse the image library stored on the mobile device by touching the screen, swiping their fingers, or using other input devices (such as a mouse, keyboard, etc., depending on the type of mobile device). Once the user finds and selects the image they wish to display, they can confirm the selection using gestures such as tapping, double-tapping, or long-pressing. The control program will capture these user actions and process the selected image as the target image.

[0074] The display control method for mobile device casings in this embodiment provides users with a more intuitive and flexible way to select the images they wish to display. Users can easily browse and select images within the user interface of the control program without leaving the application or switching to other interfaces. This design not only enhances the user experience but also makes the entire process smoother and more efficient.

[0076] The mobile device generates a first preset instruction through the control module, and controls the instruction sending module to send the first preset instruction to the instruction receiving module of the mobile device shell; the mobile device display shell receives the instruction sent by the mobile device through the instruction receiving module; when the instruction is the first preset instruction, the first radio frequency unit is triggered to start working.
