Abstract
Description
Methods, devices, equipment, and media for switching backup signal interfaces of Mini LED displays
[0001] This application is based on and claims priority to Chinese Patent Application No. 202410810393.6, filed on June 21, 2024, the entire contents of which are incorporated herein by reference. Technical Field
[0002] This application relates to the field of signal switching technology, and in particular to a method, apparatus, device and medium for switching backup signal interfaces of a Mini LED display. Background Technology
[0003] Mini LED displays are desktop display devices that utilize Mini LED backlighting technology. Some medical displays in existing operating rooms are Mini LED displays. However, medical displays in interventional operating rooms need to be connected to two signal interfaces simultaneously: one signal A as the main display interface and the other signal B as a backup display interface. In the event of an emergency with the surgical equipment, the backup signal needs to be activated immediately.
[0004] The current method prioritizes the backup signal for display. When the backup signal is available, the monitor switches to displaying that signal to show the backup interface's display screen. However, due to excessive interference in the field environment, the current method does not effectively judge the backup signal upon receipt, which greatly increases the probability of false signal cuts, posing risks to the surgical procedure and creating safety hazards. Application content
[0005] The purpose of this application is to provide a method, apparatus, device, and medium for switching the backup signal interface of a Mini LED display, so as to accurately determine the validity of the backup signal, avoid erroneous switching of the backup signal, and improve security.
[0006] To address the aforementioned technical problems, this application provides a method for switching the backup signal interface of a Mini LED display, comprising:
[0007] When the Mini LED display enters the target screen mode, it will display the signal screen of the main signal interface and hide the signal screen of the backup signal interface.
[0008] When the data enable signal received by the backup signal interface meets the preset requirements, the video timing information of the backup signal interface is received.
[0009] The video timing information is subjected to resolution matching processing to obtain the matching result;
[0010] If the matching result is a successful match, then the pixel data of the video frame in the backup signal interface is captured to obtain the target pixel data;
[0011] The target pixel data is compared byte by byte with preset data to obtain the comparison result;
[0012] If the comparison result shows that the target pixel data matches the bytes of the preset data, then the Mini LED display will hide the signal screen of the main signal interface and display the signal screen of the backup signal interface.
[0013] Further, the step of receiving video timing information from the backup signal interface when the data enable signal received by the backup signal interface meets preset requirements includes:

[0017] Further, the step of performing resolution matching processing on the video temporal information to obtain a matching result includes:
[0018] The video timing information is parsed to obtain the resolution of the video timing information, thereby obtaining the target resolution.
[0019] The target resolution is matched with the preset resolution.
[0020] If the target resolution matches the preset resolution, the matching result is a successful match.
[0021] If the target resolution does not match the preset resolution, the matching result is a failure.
[0022] Further, if the matching result is successful, then the pixel data of the video frame in the backup signal interface is captured to obtain the target pixel data, including:
[0023] If the matching result is successful, then capture N consecutive video frames from the backup signal interface, and capture the first M pixels of each video frame to obtain the target pixel data, wherein the target pixel data is luminance data in YUV format, and N and M are positive integers.
[0024] Furthermore, after comparing the target pixel data with preset data byte by byte to obtain the comparison result, the method further includes:
[0025] If the comparison result shows that the target pixel data and the preset data do not match in bytes, then the data enable signal is determined to be invalid.
[0026] Clear the status bits of the byte match to re-monitor the backup signal interface.
[0027] Furthermore, when the Mini LED display enters the target screen mode, displaying the signal screen of the main signal interface and hiding the signal screen of the backup signal interface includes:
[0028] When the user option corresponding to the target screen mode is triggered, the Mini LED display will enter the target screen mode;
[0029] The signal screen of the main signal interface is used as the main window so that the Mini LED display shows the signal screen of the main signal interface;
[0030] The signal display of the backup signal interface is used as a sub-window, and the sub-window is superimposed on the main window to hide the signal display of the backup signal interface.

[0034] A resolution matching unit is used to perform resolution matching processing on the video timing information to obtain a matching result;
[0035] The data capture unit is used to capture the pixel data of the video frame in the backup signal interface to obtain the target pixel data if the matching result is a successful match.
[0036] A byte comparison unit is used to compare the target pixel data with preset data byte by byte to obtain a comparison result;
[0037] The interface switching unit is used to hide the signal screen of the main signal interface and display the signal screen of the backup signal interface if the comparison result shows that the target pixel data matches the bytes of the preset data.
[0038] Furthermore, the timing information receiving unit includes:

[0053] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing drawings of this application, are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.
[0054] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.
[0055] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.
[0056] The present application will now be described in detail with reference to the accompanying drawings and embodiments.
[0057] It should be noted that the backup signal interface switching method for Mini LED displays provided in this application is generally executed by electronic devices, and correspondingly, the backup signal interface switching device for Mini LED displays is generally configured in electronic devices.
[0058] Please refer to Figure 1, which illustrates a specific implementation of a backup signal interface switching method for a Mini LED display.
[0059] It should be noted that if substantially the same result is obtained, the method of this application is not limited to the process sequence shown in Figure 1, and the method includes the following steps:
[0060] S1: When the Mini LED display enters the target screen mode, the Mini LED display will display the signal screen of the main signal interface and hide the signal screen of the backup signal interface.
[0061] Specifically, in target screen mode, the monitor outputs two screens simultaneously. In this mode, the monitor displays the main signal interface's signal screen in full screen, while a secondary screen is hidden below it to receive and analyze the backup signal. The user can only see the main screen displayed in full screen and cannot see the hidden backup signal screen. When the Mini LED monitor is in target screen mode, both the main and backup signal interface's signal screens play content in real time; only the main signal interface's signal screen is displayed, while the backup signal interface's signal screen is hidden.
[0062] In one specific embodiment, the medical display in the operating room is a Mini LED display. This medical display is generally in target image mode and has two or more signal interfaces, one of which serves as the primary signal interface and the other as a backup signal interface. Under normal circumstances, the medical display shows the image displayed on the primary signal interface. When an emergency occurs with the surgical equipment, the backup signal interface needs to be activated immediately, thus switching to the display image displayed on the backup signal interface.
[0063] Please refer to Figure 2, which illustrates a specific implementation of step S1, as detailed below:
[0064] S11: When the user option corresponding to the target screen mode is triggered, the Mini LED display will enter the target screen mode.
[0065] S12: Use the signal screen of the main signal interface as the main window so that the Mini LED display shows the signal screen of the main signal interface.
[0066] S13: Use the signal screen of the backup signal interface as a sub-window and overlay the sub-window under the main window to hide the signal screen of the backup signal interface.
[0067] Specifically, a User option (the user option corresponding to the target screen mode) is added to the existing menu of the Mini LED display. This User option utilizes PIP (Picture-in-Picture) technology to change the sub-window, which would normally be superimposed on the main PIP window, to be superimposed below the main window, thus hiding the signal screen of the backup signal interface. Therefore, in this embodiment, when the user option corresponding to the target screen mode is triggered, the Mini LED display enters the target screen mode, then uses the signal screen of the main signal interface as the main window to display the signal screen of the main signal interface; finally, the signal screen of the backup signal interface is used as a sub-window and superimposed below the main window to hide the signal screen of the backup signal interface.
[0068] S2: When the data enable signal received by the backup signal interface meets the preset requirements, the video timing information of the backup signal interface is received.
[0069] Specifically, when a user needs the Mini LED display to switch signal interfaces and display the signal from the backup signal interface, a data enable signal is continuously sent to the backup signal interface. Since there is a possibility of false triggering of the backup signal, upon receiving the data enable signal, it is necessary to determine whether it meets preset requirements to avoid false triggering. When the data enable signal received by the backup signal interface meets the preset requirements, the video timing information from the backup signal interface is received.
[0070] Please refer to Figure 3, which illustrates a specific implementation of step S2, as detailed below:
[0071] S21: When the backup signal interface receives the data enable signal, the duration of the continuous request for the data enable signal is obtained.
[0072] S22: Compare the duration of the continuous request with the preset duration.
[0073] S23: If the duration of the continuous request exceeds the preset duration, it is determined that the data enable signal meets the preset requirements, and the video timing information of the backup signal interface is received.
[0074] Specifically, to avoid accidental triggering of the backup signal display, this embodiment of the application needs to obtain the duration of the continuous request for the data enable signal when the backup signal interface receives the data enable signal, and then compare the duration of the continuous request with a preset duration; if the duration of the continuous request exceeds the preset duration, it is determined that the data enable signal meets the preset requirements, and the video timing information of the backup signal interface is received; if the duration of the continuous request does not exceed the preset duration, it is determined that the data enable signal does not meet the preset requirements, and the backup signal interface is triggered, and no subsequent switching operation of the backup signal interface is performed at this time.
[0075] It should be noted that the preset duration is set according to the actual situation and is not limited here. In one specific embodiment, if the continuous request duration exceeds 5 seconds, the data enable signal is determined to meet the preset requirements.
[0076] S3: Perform resolution matching processing on the video timing information to obtain the matching result.
[0077] Please refer to Figure 4, which illustrates a specific implementation of step S3, as detailed below:
[0078] S31: The video timing information is parsed to obtain the resolution of the video timing information and thus the target resolution is obtained.
[0079] S32: Match the target resolution with the preset resolution.
[0080] S33: If the target resolution matches the preset resolution, the matching result is a successful match.
[0081] S34: If the target resolution does not match the preset resolution, the matching result is a failure.
[0082] Specifically, the video timing information is parsed to obtain its resolution, thus determining the target resolution. Since the video resolution corresponding to the backup signal interface is uniform, a preset resolution is set beforehand. The target resolution is then matched with the preset resolution both horizontally and vertically. If the target resolution matches the preset resolution, the matching result is considered successful; if they do not match, the matching result is considered unsuccessful, and no further switching to the backup signal interface is performed. Simultaneously, an alarm message can be issued.
[0083] It should be noted that the preset resolution is set according to the resolution of the video played on the Mini LED display. In one specific embodiment, the preset resolution is set to 1920×1080.
[0084] S4: If the matching result is successful, then capture the pixel data of the video frame in the backup signal interface to obtain the target pixel data.
[0085] Specifically, after the resolution matching is successful, it is necessary to capture the pixel data of the video frame in the backup signal interface. This pixel data is brightness data in YUV format.
[0086] Furthermore, a specific implementation of step S4 is provided: if the matching result is a successful match, then capture N consecutive video frames from the backup signal interface, and capture the first M pixel data of each video frame to obtain the target pixel data, wherein the target pixel data is luminance data in YUV format, and N and M are positive integers.
[0087] In this embodiment of the application, it is necessary to capture multiple pixel data points in consecutive video frames in the backup signal interface so as to compare the pixel data points in each video frame with preset data, thereby determining whether the data enable signal is a valid signal.
[0088] In one specific embodiment, three consecutive video frames are captured from the backup signal interface, and the data of the first N pixels of each video frame are captured to obtain the target pixel data.
[0089] S5: Compare the target pixel data with preset data by bytes to obtain the comparison result.
[0090] Specifically, the preset data can be defined differently depending on the scenario. It is agreed upon by the backup signal source and is generated at the source by modifying the pixel data in the first M pixels of each output video frame. For example, the preset data can be set to 0x00, 0x01, 0x02, 0x03, 0x04, 0x06.
[0091] In this embodiment of the application, each target pixel data is compared byte by byte with the preset data according to the order of data capture; if all target pixel data can match the bytes of their corresponding preset data, the comparison result is that the target pixel data and the bytes of the preset data match; if any target pixel data does not match the bytes of its corresponding preset data, the comparison result is that the target pixel data and the bytes of the preset data do not match.
[0092] Furthermore, during each byte comparison process, the target pixel data is aligned with the string corresponding to the preset data. Starting from the aligned end, the characters of the two are compared sequentially. If all characters match, it is determined that the target pixel data matches the characters of the preset data; if any character does not match, it is determined that the target pixel data does not match the characters of the preset data.
[0093] Please refer to Figure 5, which illustrates a specific implementation method after step S5, as detailed below:
[0094] S5A: If the comparison result shows that the target pixel data and the preset data do not match in bytes, then the data enable signal is determined to be invalid.
[0095] S5B: Clear the status bit of the byte match to re-monitor the backup signal interface.
[0096] Specifically, if the comparison result shows that the target pixel data does not match the bytes of the preset data, the data enable signal is determined to be invalid. After determining that the data enable signal is invalid, the byte matching status bit needs to be cleared so that the backup signal interface can be monitored again. At the same time, in order to avoid interference from invalid signals to users, such as during surgery, and to avoid interference from other information to doctors, no reminder message needs to be issued after determining that the data enable signal is invalid.
[0097] S6: If the comparison result shows that the target pixel data matches the bytes of the preset data, then the Mini LED display hides the signal screen of the main signal interface and displays the signal screen of the backup signal interface.
[0098] Specifically, if the comparison result shows that the target pixel data matches the bytes of the preset data, the data enable signal is determined to be a valid signal. The Mini LED display hides the signal screen of the main signal interface and displays the signal screen of the backup signal interface. At this point, the switching process of the backup signal interface is completed.
[0099] In this embodiment, when the Mini LED display enters the target screen mode, it displays the signal screen of the main signal interface and hides the signal screen of the backup signal interface. When the data enable signal received by the backup signal interface meets preset requirements, it receives the video timing information of the backup signal interface. The video timing information is then processed for resolution matching to obtain a matching result. If the matching result is successful, pixel data of the video frame in the backup signal interface is captured to obtain target pixel data. The target pixel data is then compared byte-by-byte with preset data to obtain a comparison result. If the comparison result shows that the target pixel data matches the bytes of the preset data, the Mini LED display hides the signal screen of the main signal interface and displays the signal screen of the backup signal interface. In this embodiment, when the data enable signal received by the backup signal interface meets preset requirements, resolution matching is performed on the video timing information, and the pixel data is compared byte-by-byte with the preset data. This allows for accurate judgment of the validity of the backup signal, avoiding accidental switching of the backup signal and improving security.

[0107] The interface switching unit 76 is used to hide the signal screen of the main signal interface and display the signal screen of the backup signal interface if the comparison result shows that the target pixel data matches the bytes of the preset data.

[0116] The second matching result unit is used to determine that the matching result is a matching failure if the target resolution does not match the preset resolution.
[0117] Furthermore, the data capture unit 74 includes:
[0118] The target pixel data capturing unit is used to capture N consecutive video frames from the backup signal interface if the matching result is a successful match, and capture the first M pixel data of each video frame to obtain the target pixel data, wherein the target pixel data is luminance data in YUV format, and N and M are positive integers.
[0119] Furthermore, after byte comparison unit 75, it also includes:
[0120] An invalid information determination unit is used to determine that the data enable signal is invalid if the comparison result shows that the target pixel data and the preset data do not match in bytes.
[0121] A status bit clearing unit is used to clear the status bit of the byte match in order to re-monitor the backup signal interface.
[0122] Furthermore, the screen hiding unit 71 includes:
[0123] The mode entry unit is used to enter the Mini LED display into the target screen mode when the user option corresponding to the target screen mode is triggered.
[0124] The main window determination unit is used to use the signal screen of the main signal interface as the main window, so that the Mini LED display can display the signal screen of the main signal interface.
[0125] The sub-window determination unit is used to use the signal screen of the backup signal interface as a sub-window and to overlay the sub-window under the main window to hide the signal screen of the backup signal interface.
[0126] In this embodiment, when the Mini LED display enters the target screen mode, it displays the signal screen of the main signal interface and hides the signal screen of the backup signal interface. When the data enable signal received by the backup signal interface meets preset requirements, it receives the video timing information of the backup signal interface. The video timing information is then processed for resolution matching to obtain a matching result. If the matching result is successful, pixel data of the video frame in the backup signal interface is captured to obtain target pixel data.

If the comparison result shows that the target pixel data matches the bytes of the preset data, the Mini LED display hides the signal screen of the main signal interface and displays the signal screen of the backup signal interface. In this embodiment, when the data enable signal received by the backup signal interface meets preset requirements, resolution matching is performed on the video timing information, and the pixel data is compared byte-by-byte with the preset data. This allows for accurate judgment of the validity of the backup signal, avoiding accidental switching of the backup signal and improving security.
