[0028] The specific implementation methods, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0029] Example 1

[0030] See also Figure 1 This embodiment provides a method, device and storage medium for adapting a display screen to a lower computer display. Through an LCD color screen and an intelligent communication protocol, the aesthetics and interactive experience of the printer's user interface are enhanced. The stability and operational reliability of the system are improved by real-time synchronization of display content and lower computer status.

[0031] The present invention provides a method for adapting a display screen to a lower computer display, comprising the following steps:

[0032] S1. The color display screen encodes all menu pages according to the microcontroller unit MCU and code framework selected by itself;

[0033] Specifically, due to the differences in the hardware structure and code framework of the color display, the number and type of menus that each color display can support are also different. Therefore, it is necessary to first determine the hardware structure and code framework of the color display before determining the final functional menu that can be realized. Among them, the hardware structure of the color display mainly refers to the MCU selected by the color display, and the code framework can be understood as the various functional modules running inside the color display, such as system management, data processing, communication, etc.

[0034] S2, the color display screen establishes a communication protocol and actively obtains instructions from the lower computer under the color display screen;

[0035] Specifically, the color display screen can generate a communication protocol based on the signal feedback from the lower computer, and then actively initiate a connection request to the lower computer. After successfully establishing a communication connection with the lower computer, it actively sends a command request message to the lower computer to obtain instructions from the lower computer. The advantage of this is that the color display screen can adapt to changes in the upper computer more flexibly, thereby achieving better compatibility and interchangeability.

[0036] S3. The lower computer uploads the menu changes and parameters to the color display screen through the communication protocol; specifically, the lower computer can upload the menu changes and parameters to the color display screen through wireless transmission, or can upload the menu changes and parameters to the color display screen through wired transmission.

[0037] S4, the color display screen displays the corresponding pages and parameters according to the received instructions of the lower computer. Specifically, the color display screen can display the corresponding pages and parameters according to the received instructions of the lower computer, so that the operator can grasp the status information of the lower computer in real time.

[0038] By pre-coding the menu pages of the color display screen to adapt to different microcontroller units and code frameworks, efficient compatibility with a variety of lower computers is achieved. The method ensures real-time data synchronization between the display screen and the lower computer by establishing an active communication protocol, thereby providing a dynamic, intuitive and user-friendly interface and enhancing the user experience. At the same time, the method optimizes the display effect, makes the information display richer and more accurate, and reduces misunderstandings of user operations. The present invention reduces development and maintenance costs and brings significant benefits to printer manufacturers and users.

[0039] Furthermore, before the color display screen encodes all menu pages according to the microcontroller unit MCU and the code framework selected by itself, it also includes: the color display screen determines its own resolution, size and number of colors; the color display screen selects a suitable MCU according to its own resolution, size and number of colors; the color display screen determines the code framework according to the MCU.

[0040] The color display determines its own resolution, size and number of colors before encoding all menu pages. This approach ensures that the display can select the most appropriate microcontroller unit (MCU) and code framework based on its own hardware characteristics. This refined adaptation process significantly improves the performance and compatibility of the display, making the display effect perfectly match the requirements of the printer's lower computer.

[0041] Further, the color display screen establishes a communication protocol and actively obtains instructions from the lower computer under the color display screen, specifically: the color display screen generates the communication protocol according to the signal fed back by the lower computer; the color display screen actively initiates a connection request to the lower computer; after successfully establishing a communication connection with the lower computer, the color display screen actively sends an instruction request message to the lower computer to obtain instructions from the lower computer;

[0042] Furthermore, the color display screen generates the communication protocol according to the signal fed back by the lower computer, specifically: the color display screen generates a first communication protocol according to the first signal fed back by the lower computer; the color display screen generates a second communication protocol according to the second signal fed back by the lower computer; wherein, the first communication protocol is used for communication between the color display screen and a first type of lower computer; and the second communication protocol is used for communication between the color display screen and a second type of lower computer.

[0043] Specifically, the color display screen realizes more intelligent and flexible display control by actively establishing a communication protocol with the lower computer. The display screen can intelligently generate the corresponding first communication protocol or second communication protocol according to the different signal types fed back by the lower computer. This design enables the display screen to adapt to various types of lower computers, greatly improving the compatibility and scalability of the system. After successfully establishing a communication connection, the display screen actively sends a command request message to ensure real-time data exchange and synchronous display with the lower computer, thereby optimizing the response speed and accuracy of the user interface. This active communication mechanism not only improves the user experience, but also enhances the reliability and efficiency of the printer operation, ensuring that users can obtain timely and accurate feedback information under different printing tasks and states.

[0044] Furthermore, after the color display screen displays the corresponding pages and parameters according to the received instructions from the lower computer, it also includes: when the color display screen recognizes that the instruction issued by the lower computer is an erroneous instruction, refusing to execute the erroneous instruction.

[0045] Specifically, through the error instruction recognition and execution rejection mechanism of the color display screen, the present invention effectively avoids system confusion or failure that may be caused by executing erroneous instructions, thereby enhancing the stability and reliability of the display system and ensuring the accuracy of user operations and the normal operation of the printer.

[0046] Furthermore, the method further includes: the color display screen automatically enters a standby mode after being started; the color display screen switches from the standby mode to a working mode when receiving a wake-up signal sent by the lower computer;

[0047] Wherein, after the color display screen maintains the working mode for a period of time, if it does not receive any signal sent by the lower computer, it will automatically switch from the working mode to the standby mode.

[0048] Specifically, through the automatic standby and wake-up mechanism of the color display, energy conservation and response speed optimization are achieved, ensuring that the display automatically enters a low-power state when inactive, and quickly switches to working mode when needed, improving the system's energy efficiency and the smoothness of user operations.

[0049] Furthermore, the method also includes: the color display screen stores multiple versions of software programs; when the color display screen receives an upgrade command sent by the lower computer, the color display screen selects a version of the software program from the multiple versions of the software program to upgrade the color display screen.

[0050] Specifically, multiple software program versions are saved through the color display screen, and the appropriate version is intelligently selected for upgrade according to the upgrade command of the lower computer, ensuring the timely update and function optimization of the display screen software, improving the stability of the system and user experience, while reducing display problems caused by software incompatibility or errors, and enhancing the reliability and advancement of the overall display system.

[0051] Furthermore, when the color display screen receives the upgrade command sent by the lower computer, the color display screen selects a version of the software program from the multiple versions of the software program to upgrade the color display screen. Specifically, the color display screen selects a version of the software program with a corresponding identification number from the multiple versions of the software program according to the identification number sent by the lower computer to upgrade the color display screen.

[0052] Specifically, the color display screen accurately selects and executes the corresponding version of the software upgrade according to the specific identification number sent by the lower computer, thereby achieving efficient and accurate update of the display screen firmware. This method ensures the pertinence and security of the upgrade process, avoids the risk of incompatibility or erroneous upgrades, and thus improves the stability and reliability of the system. At the same time, it also allows remote and automated upgrade management, reduces manual intervention, reduces maintenance costs, ensures that the color display screen always runs in the optimal software state, and provides users with a continuously improved user experience.

[0053] A device for adapting a display screen to a lower computer display comprises a processor, a memory and computer program instructions stored in the memory. When the computer program instructions are executed by the processor, the method steps for adapting a display screen to a lower computer display are implemented.

[0054] A storage medium stores computer program instructions, which, when executed by a processor, implement the above-mentioned method steps for adapting a display screen to a lower computer display.

[0055] The coordination between the color display and the printer lower computer is ensured through intelligent communication and synchronization mechanisms. First, the color display selects the appropriate microcontroller unit (MCU) and code framework according to its own hardware characteristics (resolution, size and number of colors), pre-codes all possible menu pages, and ensures the preparation of the display content. Then, the display actively communicates with the lower computer by establishing a communication protocol, and generates the corresponding communication protocol according to the feedback signal of the lower computer. Whether it is the first type or the second type of lower computer, it can ensure effective data exchange and adapt to different types of lower computers. After the display successfully establishes a communication connection with the lower computer, the display will actively request the instructions of the lower computer, and dynamically display the corresponding pages and parameters according to these instructions to achieve synchronous updates. In addition, the display can identify and refuse to execute erroneous instructions to avoid page jamming caused by erroneous instructions. The display can also automatically switch to standby mode when there is no signal, and perform software upgrades when receiving upgrade commands to ensure the stability and updateability of the system. In this way, not only the display effect and user experience are improved, but also the overall smoothness and reliability of the printer operation are ensured.

[0056] Specifically, the display automatically enters standby mode after startup and waits for the wake-up signal from the lower computer. Once the wake-up signal is received, the display switches to working mode and displays the corresponding pages and parameters according to the instructions of the lower computer. If no signal from the lower computer is received for a period of time in working mode, the display will automatically switch back to standby mode to save energy.

[0057] The display screen also has a software upgrade function, which can save multiple versions of software programs. When receiving the upgrade command sent by the lower computer, it selects the correct software version for upgrade according to the identification number provided by the lower computer, thereby keeping the system updated and optimized. The entire process improves the compatibility and user experience of the display screen through intelligent communication protocols and display management, while reducing the development workload and accelerating the progress of product updates.
