[0035] The present application provides a display screen driving control method, referring to Figure 1 , Figure 1 is a flowchart of a display screen driving control method provided by the embodiments of the present application, comprising the following steps:

[0036] Step S101, a group of serial ports is configured as a first mode, wherein the group of serial ports includes an interface for communicating with a target display screen;

[0037] Step S102, in the case that the group of serial ports has been connected with the target display screen, it is judged whether the target display screen matches the first mode;

[0038] Step S103, in the case that it is determined that the target display screen does not match the first mode, the group of serial ports is adjusted to a second mode, and communicates with the target display screen until it is determined that the target display screen matches the second mode, and a second driving program is called to drive the target display screen, wherein the second driving program is a driving program corresponding to the second mode.

[0039] Wherein, the execution subject of the above steps can be a control backplane, or a control circuit board, or a CPU mainboard, but is not limited thereto.

[0040] In the above embodiment, a group of serial ports is first configured in a first mode, and then it is determined whether the target display screen matches the first mode, that is, whether the communication or interaction between the target display screen and the first mode is normal in the first mode. Taking the example of controlling the bottom plate to perform the above operation, for example, a group of serial ports are ports for communicating or interacting with the target display screen on the control board. When it is determined that the target display screen does not match the first mode, the group of serial ports is configured in other modes, for example, adjusted to a second mode, until it is determined that the target display screen matches the second mode. The second mode includes one or more modes different from the first mode, and each mode corresponds to a type of display screen. That is, by modifying the configuration of a group of serial ports, the hardware does not need to be changed to achieve the purpose of compatibility with the target display screen, thereby improving the compatibility between the control board and the display screen and achieving the purpose of improving the application range of the control board. By automatically detecting the matching of the display screen and the serial port configuration mode, the compatibility of the drive control system with different display screens can be improved, and various display screens can be properly supported. By automatically adjusting the serial port configuration mode and switching to the second mode when it does not match, the automatic adaptation of the driver program is realized, the manual intervention is reduced, and the intelligent level of the system is improved. When using the drive control system, the user does not need to worry about the compatibility of the display screen and the driver program, and the system can automatically complete the adaptation, thereby providing a more smooth and convenient user experience. Since the system can automatically adapt to different display screens, the maintenance work caused by the mismatch of the driver program is reduced, thereby reducing the maintenance cost.

[0041] In an optional embodiment, when it is determined that the target display screen matches the first mode, a first driver program is called to drive and control the target display screen, wherein the first driver program is a driver program corresponding to the first mode.

[0042] In the above embodiment, when it is determined that the target display screen matches the first mode, the first driver program can be directly called to drive and control the target display screen. The first mode can be understood as a default mode. By automatically determining whether the target display screen matches the first mode and calling the corresponding first driver program in the case of matching, the accuracy of the driver program selection is ensured. The user does not need to manually select the driver program, and the system will automatically select the appropriate driver program according to the characteristics of the display screen, which greatly simplifies the user's operation process and reduces the operation difficulty. Since the system can automatically adapt to different display screens, the maintenance and technical support requirements caused by improper selection of the driver program are reduced, thereby reducing the overall maintenance cost.

[0043] In an optional embodiment, the group of serial ports includes a first port, a second port, a third port and a fourth port, and configuring the group of serial ports into a first mode includes: defining the first port as a serial communication mode, defining the second port as a serial communication mode, and defining the third port and the fourth port as an idle state; wherein the driver corresponding to the first mode is a first driver, and the first driver is a touch display screen driver.

[0044] In the above embodiment, the group of serial ports can include four ports, and the first mode corresponds to the configuration of the group of serial ports, and the first mode is matched with the touch display screen. If the currently connected target display screen is a touch display screen, the group of serial ports and the target display screen can normally communicate or interact, i.e., they are matched. If the currently connected target display screen is not a touch display screen, the two cannot normally communicate or interact, i.e., they are not matched. As shown in FIG. 1, the ports Port1-Port4 of the control board correspond to the group of serial ports, and different configurations of the group of serial ports can achieve the purpose of matching with different types of display screens. For example, configuring the group of serial ports into the first mode can match the control board with the touch display screen. Figure 2

[0045] In an optional embodiment, configuring the group of serial ports into a second mode includes at least one of the following: configuring the group of serial ports into a first sub-mode, the first sub-mode being used to indicate that the first port is defined as a data line port, the second port is defined as a clock line port, the third port is defined as a chip selection port of a liquid crystal display driving chip, and the fourth port is defined as a chip selection port of a first type of key scanning chip, and the second mode includes the first sub-mode; configuring the group of serial ports into a second sub-mode, the second sub-mode being used to indicate that the first port is defined as an idle state, the second port is defined as a chip selection port of a second type of key scanning chip, the third port is defined as a data line port, and the fourth port is defined as a clock line port, and the second mode includes the second sub-mode; configuring the group of serial ports into a third sub-mode, the third sub-mode being used to indicate that the first port is defined as a key reading port, the second port is defined as a control port for closing the display, the third port is defined as a data line port, and the fourth port is defined as a clock line port, and the second mode includes the third sub-mode.

For different types of display screens, only the configuration of a group of serial ports needs to be modified to match the corresponding type of display screen, without changing the hardware of the control board, so that multiple types of display screens can be matched, facilitating later maintenance and upgrading, and avoiding the problem of increased cost caused by hardware changes. Since the system can automatically identify and adapt to different display screens, the maintenance and upgrading costs caused by improper configuration are reduced; at the same time, the embodiments of the present application provide an extensible serial port configuration framework, which provides support for future new technologies and new needs. Providing multiple serial port configuration options for sub-modes solves the problem of flexible configuration of multi-purpose serial ports, improves the adaptability of display screen driving and control, simplifies the hardware design process, reduces maintenance and upgrading costs, and improves the reliability and stability of the system, while supporting the extension of future technologies.

[0048] In the above embodiment, each sub-mode corresponds to a type of display screen respectively, that is, by modifying the configuration of a group of serial ports, the control board can be applicable to different types of display screens, by configuring corresponding second drivers for different sub-modes, for example, the driver of the display screen corresponding to the first sub-mode is a segment code liquid crystal screen driver, that is, the first sub-mode is matched with the segment code liquid crystal screen, and the second sub-mode is matched with the first LED display screen, and the third sub-mode is matched with the second LED display screen, for example, the first LED display screen is a TM1668 LED display screen, and the second LED display screen is a 74HC164 LED display screen, this method ensures that the driver can be optimized for a specific type of display screen, and improves the applicability of the control board. In this embodiment, only the second mode includes the above three sub-modes as an example, in actual application, other sub-modes can also be included, that is, it can also be applicable to other types of display screens. By providing corresponding drivers for different hardware configurations, this method improves the compatibility of the system with various hardware, reduces display problems caused by incompatibility; this method provides multiple types of drivers, which can meet the needs of users for different types of display screens in different application scenarios; by ensuring the accurate matching of hardware configuration and driver, this method improves the stability and reliability of the system, reduces faults caused by driver errors; enhances the compatibility of the system, and meets the diversified needs of users.

[0049] In an optional embodiment, in the case of determining that the target display screen does not match the first mode, the set of serial ports is adjusted to the second mode and communicates with the target display screen until it is determined that the target display screen matches the second mode, comprising: in the case of determining that the target display screen does not match the first mode, configuring the set of serial ports to a first sub-mode; sending a command to read a first key scan result according to a first communication protocol, wherein the first communication protocol is a communication protocol corresponding to the first sub-mode; in the case of determining that the 5th key value is 1 based on the first key scan result, determining that the target display screen matches the first sub-mode, wherein the second driver is a segment code liquid crystal screen driver, and the segment code liquid crystal screen driver is a driver corresponding to the first sub-mode; in the case of determining that the 5th key value is not 1 based on the first key scan result, configuring the set of serial ports to a second sub-mode; sending a command to read a second key scan result according to a second communication protocol, wherein the second communication protocol is a communication protocol corresponding to the second sub-mode; in the case of determining that the 20th key value is 1 based on the second key scan result, determining that the target display screen matches the second sub-mode, wherein the second driver is a first LED display screen driver, and the first LED display screen driver is a driver corresponding to the second sub-mode; in the case of determining that the 20th key value is not 1 based on the second key scan result, configuring the set of serial ports to a third sub-mode; sending a command to read a third key scan result according to a third communication protocol, wherein the third communication protocol is a communication protocol corresponding to the third sub-mode; in the case of determining that the 8th key value is 1 based on the third key scan result, determining that the target display screen matches the third sub-mode, wherein the second driver is a second LED display screen driver, and the second LED display screen driver is a driver corresponding to the third sub-mode.

[0050] In the above embodiment, when it is determined that the first mode does not match the target display screen currently connected, a group of serial ports is configured as a first sub-mode in the second mode, the first sub-mode corresponds to a segment code liquid crystal screen, in the first sub-mode, communication interaction is performed with the target display screen to obtain a first key scanning result, and then it is judged whether the target display screen currently connected matches the first sub-mode. If yes, it is determined that the target display screen currently connected is a segment code liquid crystal screen. If no, the configuration of the group of serial ports is modified to a second sub-mode, the second sub-mode corresponds to a first LED display screen. As described above, in the second sub-mode, communication interaction is performed with the target display screen to obtain a second key scanning result, and then it is judged whether the target display screen currently connected matches the second sub-mode. If yes, it is determined that the target display screen currently connected is a first LED display screen. If no, the configuration of the group of serial ports is modified to a third sub-mode, the third sub-mode corresponds to a second LED display screen. For example, the first LED display screen is a TM1668 LED display screen, and the second LED display screen is a 74HC164 LED display screen, and so on, until it is determined that the target display screen currently connected matches. Through the technical solution, the purpose of automatically detecting the display screen type and adapting the corresponding driver program can be achieved. Through the intelligent detection process, manual intervention is reduced, and the automation and intelligent level of the system is improved. When a user uses different types of display screens, the system can automatically adapt and provide the best display effect, thereby optimizing the user experience. The user does not need to manually select or configure the driver program, and the system can automatically complete the adaptation, reducing the complexity of operation. Since the system can automatically adapt different display screens and communication protocols, the maintenance and support cost caused by improper selection of the driver program or error of the communication protocol is reduced.

[0051] In an optional embodiment, the step of judging whether the target display screen matches the first mode includes: obtaining a target file according to a fourth communication protocol, wherein the target file is a message header file sent by the target display screen; in a case where it is determined that the message header file meets the fourth communication protocol standard, it is judged that the target display screen matches the first mode; and in a case where it is determined that the message header file does not meet the fourth communication protocol standard, it is judged that the target display screen does not match the first mode.

[0052] In the above embodiment, in a case where the group of serial ports is configured as the first mode, a message header file can be obtained from the target display screen according to the corresponding communication protocol. When it is determined that the message header file meets the communication protocol standard, it is judged that the target display screen matches the first mode, and otherwise, it is judged that the target display screen does not match the first mode.
