[0021] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. Based on the described embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure. In the following description, some specific embodiments are for descriptive purposes only and should not be construed as limiting this disclosure in any way, but are merely examples of embodiments of this disclosure. Conventional structures or constructions will be omitted where they may cause confusion in understanding this disclosure. It should be noted that the shapes and dimensions of the components in the figures do not reflect actual size and proportion, but are only schematic representations of the contents of the embodiments of this disclosure.

[0022] Unless otherwise defined, the technical or scientific terms used in the embodiments of this disclosure shall have the ordinary meaning as understood by those skilled in the art. The terms "first," "second," and similar words used in the embodiments of this disclosure do not indicate any order, quantity, or importance, but are merely used to distinguish different components.

[0023] Furthermore, in the description of the embodiments disclosed herein, the terms "connected to" or "linked" can refer to a direct connection between two components, or to a connection between two components via one or more other components, wherein the connection method is electrical connection or electrical coupling. Additionally, the two components can also be connected or coupled via wired or wireless means.

[0024] Figure 1 A schematic diagram of multiple display terminals is shown as an example.

[0025] like Figure 1 As shown, in a display scenario, content is displayed through four display terminals: DT1, DT2, DT3, and DT4.

[0026] For example, four display terminals DT1, DT2, DT3, and DT4 can display the same image. When all four display terminals DT1, DT2, DT3, and DT4 are displaying normally, the image displayed on display terminal DT2 is darker than that of display terminals DT1, DT3, and DT4 because the display brightness of display terminal DT2 is lower than that of display terminals DT1, DT3, and DT4. The display effect of display terminal DT2 is different from that of display terminals DT1, DT3, and DT4.

[0027] If four display terminals DT1, DT2, DT3, and DT4 simultaneously display screen information to the user, the user may perceive that the light-emitting element in display terminal DT2 is aging and exhibiting display abnormalities, thus affecting the user's visual experience.

[0028] This disclosure provides a control method for display terminals, which enables unified control of multiple display terminals, achieves consistency in working modes and display modes of multiple display terminals, and improves the overall display effect of the display terminal group.

[0029] Figure 2 A flowchart illustrating a control method for a display terminal according to an embodiment of the present disclosure is shown.

[0030] like Figure 2 As shown, the control method 200 for the display terminal includes steps S210 to S230.

[0031] In operation S210, display parameters of the same type are obtained from multiple display terminals, resulting in multiple display parameter values.

[0032] In this embodiment of the disclosure, the multiple display terminals can be multiple display terminals that need to achieve consistent display, and the display terminals can display screen content to the user. For example, the multiple display terminals can be multiple monitors installed in a store, multiple electronic screens installed in a museum, or multiple electronic screens installed on a bulletin board.

[0033] In this embodiment of the disclosure, the display parameters can be the hardware parameters of the display terminal. By adjusting the display parameters of the display terminal, the display mode of the display terminal can be adjusted. For example, the types of display parameters include, but are not limited to, resolution, brightness, contrast, color saturation, hue, color temperature, color levels, layout parameters, frame rate, and playback speed. The display parameter values ​​can be adjusted automatically or manually.

[0034] For example, the display parameter values ​​of the display terminal can be preset or set by default after the display terminal is powered on.

[0035] In operation S220, in response to the fact that multiple display parameter values ​​are not completely consistent, the multiple display parameter values ​​are adjusted within the target range so that the adjusted multiple display parameter values ​​are consistent with each other.

[0036] In this embodiment of the disclosure, if the display parameter values ​​of multiple display terminals are not completely consistent, the display modes of the multiple display terminals may also be not completely consistent. When the display modes of multiple display terminals are inconsistent, the display effects of the display screens of the multiple display terminals may also be inconsistent, which may lead users to mistakenly believe that a certain display terminal is displaying abnormally.

[0037] In the embodiments of this disclosure, the fact that multiple display parameter values ​​are not completely consistent indicates that for a certain type of display parameter, among multiple display terminals, at least one display terminal has a display parameter value that is inconsistent with the display parameter values ​​of other display terminals.

[0038] For example, regarding a display parameter of resolution, among multiple display terminals, one display terminal may have a resolution inconsistent with the resolutions of the other display terminals. For instance, this display terminal may have a resolution of 2K, while the remaining display terminals all have a resolution of 4K.

[0039] For example, regarding brightness, the brightness of some display terminals differs from that of others. For instance, some display terminals have a brightness of 800, while others have a brightness of 1000.

[0040] In this embodiment of the disclosure, the target range is determined based on the adjustment range of each of the multiple display terminals for the same type of display parameter. The adjustment range of the display parameter is the adjustable range allowed by the display terminal. The adjustment ranges of the display parameters of the multiple display terminals may be the same or may not be completely the same.

[0041] In this embodiment of the disclosure, the target range is an adjustment range allowed by multiple display terminals. Within the target range, the display parameters of multiple display terminals can be adjusted, avoiding adjustments that exceed the allowable range of multiple display terminals.

[0042] In operation S230, multiple display terminals are controlled to display images based on the adjusted display parameter values.

[0043] In this embodiment of the disclosure, when the display parameter values ​​of multiple display terminals are identical, the multiple display terminals can display their respective content with the same display effect. In this case, the display effects of the multiple display terminals can present a consistent visual effect to the user.

[0044] In this embodiment of the disclosure, the display parameter value can be adjusted via the menu bar of the display terminal. For example, the background program adjusts the display parameter value in the menu bar of the display terminal, and the main control unit of the display terminal outputs a corresponding control signal based on the adjusted display parameter value. This allows the source drive circuit in the display terminal to output a corresponding data signal based on the control signal, and the display panel of the display terminal can display based on the data signal, so that the display effect matches the adjusted display parameter value.

[0045] In this embodiment of the disclosure, by performing unified control on multiple display terminals, the consistency of working modes and display modes of multiple display terminals is achieved, thereby improving the overall display effect of multiple display terminal groups and enhancing the visual experience provided to users by multiple display terminals.

[0046] In some embodiments, adjusting multiple display parameter values ​​within a target range in operation S220 so that the adjusted multiple display parameter values ​​are consistent with each other may include: determining a common range among the multiple adjustment ranges as a target range based on the adjustment range of each of the multiple display parameters; determining the display parameter value that falls within the target range the most times among the multiple display parameter values ​​as the target display parameter value; and adjusting all multiple display parameter values ​​to the target display parameter value.

[0047] In this embodiment of the disclosure, the common range can be a range covered by the adjustment ranges of multiple display parameters, and the multiple display parameters can be adjusted within this common range. The target display parameter value can be determined based on the target range and the multiple display parameter values.

[0048] For example, multiple display parameter values ​​are the currently set display parameter values ​​for multiple display terminals. If the current display parameter value of a display terminal is within the target range, you can select the current display parameter value of that display terminal as the target display parameter value, and then adjust the current display parameter values ​​of the remaining display terminals to the target display parameter value. Using the display parameter value that falls within the target range the most times among the multiple display parameter values ​​as the target display parameter value can reduce the number of display terminals whose display parameters need to be adjusted.

[0049] For example, the brightness values ​​of five display terminals are 1000, 500, 400, 500, and 200, respectively. The maximum allowed brightness values ​​for the five display terminals are 2000, 800, 800, 800, and 800, respectively. Based on this, the maximum value within the target range for the five display terminals can be determined to be 800. Since the brightness value of 500 is the mode among the five display parameters, it can be determined that the brightness value of 500 is the brightness value that appears most frequently within the target range, and this brightness value of 500 is taken as the target brightness value.

[0050] Combination Figure 3 The principle of determining the target range is illustrated. Figure 3 A schematic diagram illustrating the target scope according to embodiments of the present disclosure is shown. For example, Figure 3 The brightness adjustment ranges of the first display terminal (range1), the second display terminal (range2), the third display terminal (range3), and the fourth display terminal (range4) are schematically shown.

[0051] like Figure 3 As shown, the brightness adjustment range of the first display terminal is range 1 from 0 to 1000, the brightness adjustment range of the second display terminal is range 2 from 0 to 600, the brightness adjustment range of the third display terminal is range 3 from 200 to 1000, and the brightness adjustment range of the fourth display terminal is range 4 from 0 to 800.

[0052] The common range of adjustment ranges (range1, range2, range3, and range4) is 200–600. The brightness of the first, second, third, and fourth display terminals is all allowed to be adjusted within this range. Therefore, the target range (rangeT) is 200–600. When the brightness of the first, second, third, and fourth display terminals is not completely consistent, their brightness is adjusted within the target range of 200–600 to make their brightness values ​​consistent.

[0053] In this embodiment of the disclosure, the target display parameter value may be the current brightness value of the first display terminal, the second display terminal, the third display terminal, and the fourth display terminal that falls within the target range rangeT the most times.

[0054] For example, the current brightness value of the first display terminal is 800, the current brightness value of the second display terminal is 600, the current brightness value of the third display terminal is 600, and the current brightness value of the fourth display terminal is 500. The current brightness value within the target range rangeT most frequently is 600, therefore the target brightness value can be 600. In this case, only the brightness of the first and fourth display terminals can be adjusted, reducing the number of adjustments.

[0055] In this embodiment of the disclosure, the target display parameter value can be any brightness within the target range rangeT.

[0056] For example, the current brightness value of the first display terminal is 800, the current brightness value of the second display terminal is 600, the current brightness value of the third display terminal is 600, and the current brightness value of the fourth display terminal is 500. Based on the display requirements of the actual display scenario, the target brightness value is determined to be 400. In this case, the brightness values ​​of the first, second, third, and fourth display terminals are all adjusted to 400 to meet various display needs in different display scenarios.

[0057] In some embodiments, adjusting multiple display parameter values ​​within a target range in operation S220 so that the adjusted multiple display parameter values ​​are consistent with each other may further include: determining that the minimum value among the multiple display parameters is a specified display parameter value; and adjusting all multiple display parameter values ​​to the specified display parameter value in response to the specified display parameter value being within the target range.

[0058] In this embodiment of the disclosure, the minimum value of multiple display parameter values ​​is used as the target display parameter value, which can take into account the display performance of multiple display terminals.

[0059] In embodiments of this disclosure, a specified display parameter value represents a parameter value with weaker display performance. For example, if the minimum value indicates the weakest display performance, the minimum value is used as the target display parameter value. Similarly, if the maximum value indicates the weakest display performance, the maximum value is used as the target display parameter value.

[0060] For example, multiple display terminals may support inconsistent display performance, and their ability to perform on the same display metric may also differ. By using the minimum value of multiple display parameter values ​​as the target display parameter value, backward compatibility is achieved among the display terminals, ensuring that all terminals can display correctly based on the target display parameter value.

[0061] Referring to the brightness adjustment ranges described above: the first display terminal has a range of 0-1000 (range1), the second display terminal has a range of 0-600 (range2), the third display terminal has a range of 200-1000 (range3), and the fourth display terminal has a range of 0-800 (range4). The current brightness value of the first display terminal is 800, the second display terminal is 600, the third display terminal is 600, and the fourth display terminal is 500.

[0062] Since a brightness value of 600 is the maximum brightness supported by the second display terminal, it may not be able to maintain a stable brightness of 600 for an extended period. Therefore, to ensure normal display on each display terminal, a target display parameter value of 500 for the fourth display terminal can be used, adjusting the brightness values ​​of the first, second, and third display terminals downwards to 500. At a brightness value of 500, all four display terminals can display the image correctly and stably.

[0063] In this embodiment of the disclosure, when the minimum value of multiple display parameter values ​​is outside the target range, the target display parameter value can be redefined within the target range. For example, the minimum value among multiple display parameter values ​​that are within the target range can be redefined to determine the target display parameter value.

[0064] For example, referring to the previous description, the target range can be 200 to 600. The current brightness value of the first display terminal is 800, the current brightness value of the second display terminal is 200, the current brightness value of the third display terminal is 600, and the current brightness value of the fourth display terminal is 500. The minimum brightness value among these multiple current brightness values ​​is 200, but the brightness value of 200 is outside the target range, and the third display terminal does not support the display of a brightness value of 200. Therefore, within the target range, a new brightness value of 500 is determined as the target brightness, and the brightness values ​​of the first, second, third, and fourth display terminals are all adjusted to 500, so that the brightness display effect of the first, second, third, and fourth display terminals is consistent.

[0065] Based on the display parameters of the display terminal shown in Table 1, the adjustment method of the display parameters is illustrated.

[0066] Table 1

[0067]

[0068] Table 1 shows the display parameters and corresponding values ​​for various types of display terminals 1, 2, and 3. The display parameters include screen type, resolution, pixel density, brightness, contrast ratio, frame rate, color accuracy, color gamut, and power consumption.

[0069] The display terminal 1 has an OLED screen with a resolution of 2K, a pixel density of 80ppi, a brightness of 1000, a contrast ratio of 1000000:1, and supports High Dynamic Range Imaging (HDR). The frame rate is 144, the color accuracy is ΔE < 1, the color gamut is in accordance with the Digital Cinema Initiatives-Protocol 3 (DCI-P3) standard, the power consumption is 350W, and the standby power consumption is 0.5W.

[0070] The display terminal 2 has an LCD screen with a resolution of 3K, a pixel density of 100ppi, a brightness of 900, a contrast ratio of 1400:1, a frame rate of 144, a color accuracy of ΔE<1.5, a color gamut of DCI-P3 standard, a power consumption of 350W, and a standby power consumption of 0.5W.

[0071] The display terminal 3 has an LCD screen with a resolution of 3K, a pixel density of 100ppi, a brightness of 900, a contrast ratio of 1400:1, a frame rate of 144, a color accuracy of ΔE<1.5, a color gamut of DCI-P3 standard, a power consumption of 350W, and a standby power consumption of 0.5W.

[0072] Based on the above display parameters, it can be seen that the display parameter values ​​of the same type of display parameters are consistent for display terminals 2 and 3. However, the display parameter values ​​of the same type of display parameters for display terminals 1, 2, and 3 are not entirely consistent. Therefore, for the same type, the display parameter values ​​of display terminals 1 can be adjusted using the display parameter values ​​of display terminals 2 and 3 as target display parameter values. Alternatively, the display parameter values ​​of display terminals 2 and 3 can be adjusted using the display parameter value of display terminal 1 as the target display parameter value.

[0073] Since the resolution of display terminal 1 is the minimum among multiple resolutions, if display terminal 2 and display terminal 3 support 2K resolution, the resolution of display terminal 1 will be used as the target resolution, and the resolution of both display terminal 2 and display terminal 3 will be adjusted from 3K to 2K.

[0074] Pixel density is related to resolution. When the resolution of display terminal 2 and display terminal 3 is reduced, the pixel density of display terminal 2 and display terminal 3 will also be reduced accordingly, so that the pixel density of display terminal 1, display terminal 2 and display terminal 3 are the same.

[0075] Since the brightness values ​​of display terminal 2 and display terminal 3 are the minimum brightness values ​​among multiple brightness values, when display terminal 1 supports a brightness value of 900, the brightness value of display terminal 1 will be adjusted from 1000 to 900 with the brightness value of display terminal 2 as the target brightness value.

[0076] Since the contrast ratios of display terminal 2 and display terminal 3 are the minimum among multiple contrast ratios, when display terminal 1 supports a contrast ratio of 1400:1, the contrast ratio of display terminal 1 will be adjusted from 1000000:1 to 1400:1, and the HDR function of display terminal 1 will be turned off, with the contrast ratio of display terminal 2 as the target contrast ratio.

[0077] Since the color accuracy of display terminal 2 and display terminal 3 is the maximum value among multiple color accuracy (the color accuracy of display terminal 2 and display terminal 3 is lower than the color accuracy of display terminal 1), when display terminal 1 supports color accuracy customization, the color accuracy of display terminal 2 will be used as the target color accuracy, and the color accuracy of display terminal 1 will be adjusted from 1 to 1.

[0078] Display terminal 1, display terminal 2 and display terminal 3 have completely identical frame rates and color gamuts, so there is no need to adjust the frame rates and color gamuts of display terminal 1, display terminal 2 and display terminal 3.

[0079] The screen type and power consumption are determined by the hardware of the display terminal, and there is no need to adjust the screen type and power consumption of the display terminal.

[0080] In some embodiments, the operation S220, in response to the fact that multiple display parameter values ​​are not completely consistent, adjusts multiple display parameter values ​​within a target range so that the adjusted multiple display parameter values ​​are consistent with each other, may include: in response to the fact that the difference between multiple display parameter values ​​is greater than or equal to a preset threshold, determining that multiple display parameter values ​​are not completely consistent; and adjusting multiple display parameter values ​​within a target range so that the adjusted multiple display parameter values ​​are consistent with each other.

[0081] In this embodiment of the disclosure, when the differences between the display parameter values ​​of the two display terminals are small, the differences between the display effects of the two display terminals are also small, and the user may not be able to perceive the difference with the naked eye. Therefore, in order to reduce the number of adjustments, when it is determined that the differences between multiple display parameter values ​​are small, the multiple display parameter values ​​can be considered to be consistent with each other.

[0082] Table 2

[0083]

[0084] Table 2 shows the screen type, resolution, pixel density, brightness, contrast ratio, frame rate, color accuracy, color gamut, and power consumption of display terminal 1, display terminal 2, and display terminal 3, respectively.

[0085] The display terminal 1 has an OLED screen with a resolution of 2K, a pixel density of 40ppi, a brightness of 1000, a contrast ratio of 1000000∶1, and supports High Dynamic Range Imaging (HDR) function. The frame rate is 144, the color accuracy is ΔE<1, the color gamut is DCI-P3 standard, the power consumption is 350W, and the standby power consumption is 0.5W.

[0086] The display terminal 2 has an LCD screen with a resolution of 3K, a pixel density of 60ppi, a brightness of 900, a contrast ratio of 1400:1, a frame rate of 144, a color accuracy of ΔE<1.5, a color gamut of DCI-P3 standard, a power consumption of 350W, and a standby power consumption of 0.5W.

[0087] The display terminal 3 has an LCD screen with a resolution of 3K, a pixel density of 42ppi, a brightness of 900, a contrast ratio of 1400:1, a frame rate of 144, a color accuracy of ΔE<1.5, a color gamut of DCI-P3 standard, a power consumption of 350W, and a standby power consumption of 0.5W.

[0088] In this embodiment, the preset threshold can be determined based on the current display parameter values ​​of the display terminal. For example, 5% of the display parameter values ​​of the display terminal can be used as the preset threshold. If the difference in pixel density between display terminal 1 and display terminal 3 is 2 ppi, the preset threshold can be 40 * 5% = 2 ppi. Since the difference in pixel density between display terminal 1 and display terminal 3 is equal to the preset threshold, it can be considered that the pixel densities of display terminal 1 and display terminal 3 are consistent. If the difference in pixel density between display terminal 1 and display terminal 2 is 20 ppi, since the difference in pixel density between display terminal 1 and display terminal 2 is greater than the preset threshold, it can be considered that the pixel densities of display terminal 1 and display terminal 3 are inconsistent. If the difference in pixel density between display terminal 2 and display terminal 3 is 18 ppi, since the difference in pixel density between display terminal 2 and display terminal 3 is greater than the preset threshold, it can be considered that the pixel densities of display terminal 2 and display terminal 3 are inconsistent. In this case, the pixel density of display terminal 2 is adjusted with the pixel density of display terminal 1 or display terminal 3 as the target pixel density. For example, the pixel density can be adjusted by adjusting the resolution of display terminal 2.

[0089] The adjustment methods for the display parameter values ​​of other types of display parameters for display terminals 1, 2, and 3 can be found in Table 1, which outlines the adjustment methods for the display parameters of display terminals 1, 2, and 3. For simplicity, these methods will not be elaborated upon here.

[0090] Figure 4 A flowchart illustrating a control method for a display terminal according to another embodiment of the present disclosure is shown.

[0091] like Figure 4 As shown, an electronic device can be the entity executing the control method for the display terminal. For example, the electronic device can be an edge server or a cloud server. For instance, the electronic device can be an edge server, located within the same local area network as display terminals 1, 2, and 3 for local communication. The IoT platform is deployed in the edge server to execute the control method for display terminals 1, 2, and 3. Alternatively, the electronic device can be a cloud server, remotely connected to display terminals 1, 2, and 3. The IoT platform is deployed in the cloud server to execute the control method for display terminals 1, 2, and 3.

[0092] By connecting multiple display terminals to the IoT platform, centralized control of these terminals can be achieved. The display terminals can report display data to the IoT platform and also receive instructions from the platform.

[0093] In this embodiment, the application can be an application installed on an electronic device or an application installed on another server. The application can provide a front-end interface for the user, allowing the user to customize terminal group construction policies, terminal group control policies, and anomaly detection policies. The application sends the terminal group construction policies, terminal group control policies, and anomaly detection policies to the electronic device, enabling the IoT platform deployed on the electronic device to perform actions such as building terminal groups, controlling terminal groups, and detecting anomalies in display terminals 1, 2, and 3.

[0094] In this embodiment of the disclosure, the electronic device performs operation S401 to create a terminal group based on the terminal group construction strategy from the application and registration request 1, registration request 2 and registration request 3 from display terminal 1, display terminal 2 and display terminal 3.

[0095] In this embodiment of the disclosure, operation S401, creating a terminal group, may include: obtaining registration information of multiple display terminals, and dividing the multiple display terminals into multiple terminal groups based on the registration information, wherein each terminal group includes multiple display terminals with identical registration information. The display parameter values ​​of the multiple display terminals included in each of the multiple terminal groups are adjusted to be consistent with each other.

[0096] For example, registration information includes location information and user information. Based on at least one of the location information and user information, multiple display terminals are divided into multiple terminal groups. At least two display terminals included in the same terminal group have identical location information, or identical user information, or identical information and identical user information.

[0097] In this embodiment, display terminal 1, display terminal 2, and display terminal 3 respectively send registration request 1, registration request 2, and registration request 3 to the electronic device. Registration request 1, registration request 2, and registration request 3 include registration information for their respective display terminals. For example, the registration information can characterize various attribute information of the display terminals, such as location information, usage information, and user information. Based on the registration information, it can be determined whether the attributes of multiple display terminals are consistent, thereby determining whether multiple display terminals have a need for unified control.

[0098] In this embodiment of the disclosure, the registration request sent by the display terminal to the electronic device indicates that the display terminal requests centralized control from the electronic device. For example, the electronic device can divide display terminal 1, display terminal 2, and display terminal 3 into multiple terminal groups based on the terminal group construction strategy and the registration information of the display terminals.

[0099] In this embodiment of the disclosure, the registration information may include the location information of the display terminal. For example, the location attribute of the display terminal can be represented by location information such as the location where the display terminal is installed, and the usage attribute can be represented by usage information such as the content to be displayed on the display terminal. User attributes can be represented by user information such as the user of the display terminal.

[0100] For example, a terminal group construction strategy indicates that terminal groups are divided based on location information, usage information, and user information. For example, if location information indicates that the installation locations of multiple display terminals are associated, the multiple display terminals can be grouped into the same terminal group. For example, if usage information indicates that the display functions of at least two display terminals are associated, at least two display terminals can be grouped into the same terminal group. For example, if location information indicates that the installation locations of at least two display terminals are associated and usage information indicates that the display functions of at least two display terminals are associated, at least two display terminals can be grouped into the same terminal group. If it is determined that usage information indicates that the images displayed by at least two display terminals are associated, then at least two display terminals are determined to belong to the same terminal group.

[0101] In this embodiment of the disclosure, the electronic device further divides multiple display terminals into multiple terminal groups based on at least one of location information and user information, including at least one of the following: determining that at least two display terminals belong to the same terminal group when the location information indicates that at least two display terminals are located in the same spatial range; determining that at least two display terminals belong to the same terminal group when the user information indicates that at least two display terminals belong to the same user; and determining that at least two terminals belong to the same terminal group when the location information indicates that at least two display terminals are located in the same spatial range and the user information indicates that at least two terminals belong to the same user.

[0102] In this embodiment of the disclosure, the spatial range can represent the installation location of the display terminals. For example, when location information indicates that multiple display terminals are installed in the same location, the electronic device assumes that the multiple display terminals have the same display needs, and the electronic device divides the multiple display terminals into the same terminal group. For example, multiple display terminals are installed in the same store, and the multiple display terminals need to simultaneously display product information to users. For example, multiple display terminals are installed in the same conference room, and the multiple display terminals need to simultaneously display conference information to attendees.

[0103] In this embodiment of the disclosure, the image displayed by the display terminal represents the display screen of the display terminal, and the display function of the display terminal can be determined based on the display screen. For example, when multiple display terminals are instructed by a signal to display related images, the electronic device considers the multiple display terminals to be related and divides the multiple display terminals into the same terminal group. For example, multiple display terminals may all require different product information of the same brand, and the multiple display terminals are related.

[0104] In this embodiment of the disclosure, when user signals indicate that multiple display terminals belong to the same user, the electronic device also considers the multiple display terminals to be related, and classifies the multiple display terminals into the same terminal group. For example, with the user's permission or authorization, the electronic device can determine that multiple display terminals were purchased by the same user based on pre-stored purchase information of the display terminals. The electronic device considers multiple display terminals purchased by the same user to be related.

[0105] In this embodiment of the disclosure, dividing multiple display terminals into multiple terminal groups based on at least one of location information and user information may include: determining that multiple display terminals belong to the same terminal group when it is determined that the location information and user information indicate that multiple display terminals simultaneously capture the gaze information of the same user.

[0106] In this embodiment of the disclosure, the registration information may include user gaze information captured by the display terminal and the time when the user's gaze was captured. For example, when a user views a display terminal, the display terminal can determine the user's gaze information based on the position of the user's eyes and the direction of the user's face, thereby determining whether the user can view its own display screen. For example, if the display terminal captures the user's gaze, with the user's authorization, the display terminal records the current time, user information, and indicates that the user can view its own screen at the current time.

[0107] The electronic device acquires registration information from multiple display terminals and determines the user information and capture time captured by each display terminal based on the registration information. If the user information and capture time are identical across multiple registration records, the electronic device can confirm that the multiple display terminals corresponding to the multiple registration records can be viewed simultaneously by the same user.

[0108] For example, if the registration information of display terminal 1, display terminal 2 and display terminal 3 all indicate that user A's gaze was captured at 9:00 on the same day, the electronic device determines that display terminal 1, display terminal 2 and display terminal 3 can be viewed by user A at the same time, and classifies display terminal 1, display terminal 2 and display terminal 3 into the same terminal group.

[0109] For example, if the displays on multiple display terminals can be viewed by a single user simultaneously, then the multiple display terminals are considered to be within the same field of view of the user. For instance, if the user's viewing position and line of sight remain unchanged, multiple display terminals within the same field of view can be viewed simultaneously.

[0110] Since users can view the displays from multiple terminals simultaneously, the display parameter values ​​of these terminals need to be completely identical to ensure that they can present the same image to the user with the same display effect. Therefore, electronic devices group multiple display terminals located within the same field of view into the same terminal group and adjust the display parameter values ​​of the terminals within the same group to be consistent.

[0111] In this embodiment, multiple display terminals can be installed in different locations, but the images displayed by the multiple display terminals are related. In this case, the electronic device can also divide the multiple display terminals into the same terminal group and uniformly control the multiple display terminals in the same terminal group, so that the display parameter values ​​of the multiple display terminals are adjusted to be consistent with each other. For example, multiple display terminals can be installed in different stores, and the multiple display terminals need to display the same product to different consumers. The electronic device adjusts the display parameter values ​​of the multiple display terminals so that the display parameter values ​​of multiple display terminals of the same type are consistent with each other. This can ensure that the multiple display terminals can display product information to different consumers with the same display effect, thereby accurately displaying product information to different consumers and avoiding misleading consumers due to color differences or other phenomena.

[0112] In this embodiment, multiple display terminals can be installed within the same user's field of vision, but the images displayed by the multiple display terminals are unrelated. In this case, the electronic device can also divide the multiple display terminals into the same terminal group and uniformly control the multiple display terminals in the same terminal group, so that the display parameter values ​​of the multiple display terminals are adjusted to be consistent with each other. For example, multiple display terminals can be installed in the same store, and the display screens of the multiple display terminals can be viewed by consumers simultaneously. By adjusting the display parameter values ​​of the multiple display terminals to make the multiple display parameter values ​​consistent with each other, the electronic device can ensure that the multiple display terminals can simultaneously display product information to consumers with the same display effect, thereby improving the user's visual experience and preventing consumers from mistakenly believing that the display screen of a certain display terminal is abnormal.

[0113] In this embodiment of the disclosure, the electronic device performs operation S402 to adjust the display parameter values ​​based on the terminal group control strategy from the application and the display parameter values ​​1, 2, and 3 from the display terminal 1, display terminal 2, and display terminal 3.

[0114] In this embodiment, the terminal group control strategy can be related to the display needs of multiple display terminals in the terminal group. For example, display terminal 1, display terminal 2, and display terminal 3 may belong to the same terminal group. Based on the location information and user information of display terminal 1, display terminal 2, and display terminal 3, the display needs of display terminal 1, display terminal 2, and display terminal 3 can be determined, thereby determining the adjustment basis and adjustment method. The adjustment method can be, as described above, using the display parameter value that appears most frequently within the target range as the target display parameter value; or, as described above, using the maximum or minimum value among multiple display parameter values ​​as the target display parameter value; or, it can be based on whether the difference between multiple display parameter values ​​is greater than or equal to a preset threshold to determine whether the display parameter value needs to be adjusted.

[0115] In this embodiment of the disclosure, the display parameters include at least one of the following: brightness, contrast, color saturation, hue, color temperature, color gradation, and screen layout. Operation S402, adjusting the display parameter values, may include adjusting at least one of the following parameters within a target range: brightness, contrast, color saturation, hue, color temperature, color gradation, and screen layout of multiple display terminals, so that the display style of the multiple display terminals is consistent.

[0116] In the embodiments of this disclosure, the display style of the display terminal can be characterized by brightness, contrast, color saturation, hue, color temperature, color gradation, and screen layout.

[0117] For example, electronic devices can adjust the brightness of the displayed image by adjusting at least one of brightness, contrast, and color gradation. Electronic devices can adjust the color of the displayed image by adjusting at least one of color saturation, hue, and color temperature.

[0118] For example, electronic devices can enhance or weaken specific colors in a display by adjusting color saturation, hue, and color temperature, causing the displayed color to lean towards a certain color.

[0119] For example, electronic devices can adjust the color saturation of the displayed image to a cool or warm color tone, or to a red, green, yellow, or blue tone.

[0120] In this embodiment of the disclosure, the electronic device can adjust the layout of various display elements on the display screen of the display terminal by adjusting the screen layout, so that multiple display terminals can display various display elements in the same layout. This can improve the user's visual experience, allowing the user to quickly obtain related information from the display screens of multiple display terminals.

[0121] For example, a display screen includes image elements and text elements. By adjusting layout parameters, electronic devices can arrange the image and text elements in multiple display screens to be distributed vertically or horizontally. For instance, if the image and text elements in multiple display screens are all vertically distributed, the user can prioritize browsing the text elements located at the bottom of the display screen, thus quickly locating text information within the screen.

[0122] In this embodiment of the disclosure, the images displayed by the multiple display terminals can be either images or videos. The electronic device controls at least two display terminals in the same terminal group to display images based on target display parameter values, and controls the content attributes of the images displayed by the at least two display terminals to be consistent.

[0123] In this embodiment of the disclosure, at least two display terminals in the same terminal group display images, and the electronic device controls at least two display terminals in the same terminal group to display images based on target display parameter values, and the content attributes of the images remain consistent.

[0124] In this embodiment of the disclosure, at least two display terminals in the same terminal group display video. The electronic device controls at least two display terminals in the same terminal group to display video based on target display parameter values, and the content attributes of the video remain consistent.

[0125] In this embodiment of the disclosure, the content attributes may include at least one of the following: content width, content height, content exposure, content resolution, content frame rate, content theme, and content style.

[0126] For example, content width and content height can characterize the size of images and videos, as well as their position on the display screen. For instance, when the size of an image is smaller than the size of the display screen, the image can be centered on the display screen or tiled.

[0127] For example, content exposure and content resolution can characterize the sharpness of an image. Similarly, content frame rate can characterize the refresh rate of a video. Content exposure and content resolution describe the image quality, while content frame rate describes the video quality.

[0128] For example, content theme can represent the data information displayed in images and videos. Content style can represent the artistic effect of images and videos. For example, content style can include oil painting style, sketching style, relief style, watercolor style, chalk style, crayon style, photocopying style, etc. There is also a relationship between content theme and content style; the content style can be adjusted based on the content theme of images and videos to make the content style adapt to the content theme.

[0129] In this embodiment of the disclosure, by adjusting the content attributes of images and videos, the content of the images or videos to be displayed on multiple display terminals is made consistent. When multiple display terminals display the screen based on the adjusted display parameter values, it can be ensured that the display effect presented after the content attributes and display parameters are superimposed is consistent.

[0130] In this embodiment of the disclosure, the display terminal displays images and videos, and the types of display parameters include playback attributes. The electronic device can control some of the multiple display terminals to display images based on adjusted display parameter values, and control some of the multiple display terminals to display videos based on adjusted display parameter values. The playback attributes of the multiple display terminals remain consistent, and the playback attributes include at least one of playback synchronization attributes and switching synchronization attributes.

[0131] For example, electronic devices can ensure that the refresh rate of multiple display terminals is consistent by adjusting at least one of the playback synchronization attribute and switching synchronization attributes, thus avoiding the user's mistaken belief that a certain display terminal is experiencing frame drops when the refresh rate of the display screen is inconsistent.

[0132] For example, if the content displayed on the display terminal is video, electronic devices can adjust the playback synchronization attribute to ensure that multiple display terminals play the video at the same speed, thus preventing users from mistakenly believing that a particular display terminal is experiencing playback stuttering.

[0133] For example, multiple display terminals are installed in a spliced ​​manner, displaying a spliced ​​image with interconnected content. Electronic devices can adjust switching synchronization attributes to allow the display screens of multiple terminals to switch simultaneously, preventing any incomplete display across multiple terminals.

[0134] In this embodiment of the disclosure, after determining the target display parameter value, the electronic device sends the target parameter to display terminal 1, display terminal 2 and display terminal 3 respectively, thereby realizing the adjustment of the display parameter values ​​of display terminal 1, display terminal 2 and display terminal 3.

[0135] In this embodiment of the disclosure, the electronic device performs operation S402, anomaly detection, based on an anomaly detection strategy from the application and display data 1, display data 2 and display data 3 from display terminal 1, display terminal 2 and display terminal 3.

[0136] In this embodiment of the disclosure, the display data characterizes the operating state of the display terminal when displaying the image based on the target display parameter values. During the anomaly detection in operation S402, if the electronic device determines that a display terminal has a display anomaly, it can send a control command to the display terminal to readjust it.

[0137] For example, the electronic device determines that display terminal 2 is in a state where the monitor is not powered on based on display data 1, display data 2, and display data 3. The electronic device sends a control command to display terminal 2 to control the monitor of display terminal 2 to restart.

[0138] Figure 5 A flowchart illustrating a control method for a display terminal according to another embodiment of the present disclosure is shown.

[0139] Figure 5 The applications, electronic devices, display terminal 1, display terminal 2, and display terminal 3 shown can be referenced in the previous text. Figure 4 The description will not be repeated for the sake of brevity.

[0140] In this embodiment of the disclosure, the electronic device performs operations S501 to S504. In operation S501, a terminal group is created. In operation S502, the automatic adjustment function of the display terminal is determined. In operation S503, the display parameter values ​​are adjusted. In operation S504, anomaly detection is performed.

[0141] In this embodiment of the disclosure, operation S501 can refer to operation S401, and operation S504 can refer to operation S403. For the sake of simplicity, they will not be described in detail.

[0142] In this embodiment of the disclosure, based on the automatic adjustment function configuration strategy from the application, the electronic device performs operation S502 to determine the automatic adjustment function of the display terminal.

[0143] In this embodiment of the disclosure, the operation S502 to determine the automatic adjustment function of the display terminal may include: in response to the fact that a target display terminal among a plurality of display terminals has an automatic adjustment function for display parameters, disabling the automatic adjustment function of the target display terminal.

[0144] In this embodiment of the disclosure, when there is an automatic adjustment function among multiple display terminals, the electronic device adjusts the display parameter values ​​of the multiple display terminals based on the automatic adjustment function configuration strategy.

[0145] For example, the automatic adjustment function indicates that the display terminal can automatically adjust the display parameter values ​​according to the display environment or display content. Automatic adjustment functions may include automatic color adjustment, automatic contrast adjustment, automatic color accuracy adjustment, automatic resolution adjustment, automatic frame rate adjustment, and automatic operating mode adjustment.

[0146] In this embodiment of the disclosure, if it is determined that a certain display terminal supports the automatic adjustment function, the electronic device needs to determine whether all the multiple display terminals included in the terminal group support the automatic adjustment function. If there are display terminals in the terminal group that do not support the automatic adjustment function, then the automatic adjustment function of all display terminals in the terminal group that support the automatic adjustment function is turned off.

[0147] For example, for display terminals 1, 2, and 3 belonging to the same terminal group, if the electronic device determines that display terminal 1 has an automatic adjustment function while display terminals 2 and 3 do not, the electronic device sends a configuration command to display terminal 1 to instruct it to disable the automatic adjustment function. When display terminal 1 leaves the terminal group, its automatic adjustment function can be automatically enabled.

[0148] By disabling the automatic adjustment function of the display terminal, it is possible to prevent the display terminal with the automatic adjustment function from automatically adjusting its display parameter values ​​after the electronic device has adjusted the display parameter values ​​of multiple display terminals to be consistent with each other, thus avoiding inconsistencies in the display parameter values ​​of multiple display terminals.

[0149] In this embodiment of the disclosure, the automatic adjustment function configuration strategy is related to the terminal control strategy.

[0150] For example, the operation S502 to determine the automatic adjustment function of the display terminal and the operation S503 to adjust the display parameter value may include: in response to the existence of an automatic adjustment function with display parameter values ​​for multiple target display terminals among multiple display terminals, determining the display parameter values ​​of multiple target display terminals; determining the target display parameter value based on the display parameter values ​​and target range of each of the multiple target display terminals; and adjusting all the multiple display parameter values ​​to the target display parameter value.

[0151] For example, when multiple target display terminals have automatic adjustment functions for display parameter values, the electronic device can make consistent adjustments to the display parameter values ​​of all display terminals based on the display parameter values ​​of the display terminals with automatic adjustment functions as a reference.

[0152] For example, an electronic device can acquire the automatically adjusted display parameter values ​​of multiple target display terminals, select the display parameter value that appears most frequently within the target range as the target display parameter value, and adjust the display parameter values ​​of the multiple display terminals to this target display parameter value. In this case, the display effect of the multiple display terminals will approach the display effect of the automatically adjusted display terminal.

[0153] For example, if one of the multiple display terminals has an automatic adjustment function for display parameter values, the electronic device can use the display parameter values ​​of that display terminal as the target display parameter values.

[0154] Since the display parameter values ​​of a display terminal with automatic adjustment function are automatically and dynamically adjusted, using the display parameter values ​​of a display terminal with automatic adjustment function as a reference value for unified adjustment of display parameter values ​​can achieve dynamic adjustment of display parameter values ​​of multiple display terminals.

[0155] For example, the operation S502 determining the automatic adjustment function of the display terminal and the operation S503 adjusting the display parameter value may also include: in response to the automatic adjustment function that at least one target display terminal among the multiple display terminals has a display parameter value, determining the display parameter value of each of the remaining display terminals other than the at least one target display terminal; determining the target display parameter value based on the display parameter value of each of the remaining display terminals and the target range; and adjusting all the multiple display parameter values ​​to the target display parameter value.

[0156] For example, if at least one target display terminal among multiple display terminals has an automatic adjustment function for display parameter values, the electronic device can make consistent adjustments to the display parameter values ​​of all display terminals based on the display parameter values ​​of display terminals that do not have an automatic adjustment function as a reference.

[0157] For example, an electronic device can acquire display parameter values ​​from multiple display terminals that do not have automatic adjustment functions, select the display parameter value that appears most frequently within a target range as the target display parameter value, and adjust the display parameter values ​​of the multiple display terminals to this target display parameter value. In this case, if the number of display terminals with automatic adjustment functions is small, dynamic adjustment can be performed only on the display terminals with automatic adjustment functions to reduce the number of display terminals whose display parameters need to be adjusted and simplify the adjustment scheme.

[0158] In this embodiment, the electronic device can first uniformly adjust all display parameter values ​​based on the display parameter values ​​of all display terminals, then re-acquire the automatically adjusted display parameter values ​​of the display terminals with automatic adjustment functions, and further adjust the display parameter values ​​of all display terminals based on these automatically adjusted display parameter values. Alternatively, the electronic device can first uniformly adjust all display parameter values ​​based on the display parameter values ​​of all display terminals, and if it is determined that the automatically adjusted display parameter values ​​of the display terminals with automatic adjustment functions differ significantly from the target display parameter values, then further adjust the display parameter values ​​of the display terminals with automatic adjustment functions based on the target display parameter values.

[0159] In this embodiment of the disclosure, the electronic device can also directly adjust the display parameter values ​​of all display terminals based on the display parameter values ​​of the display terminal with automatic adjustment function. Alternatively, the electronic device can directly adjust the display parameter values ​​of all display terminals based on the display parameter values ​​of the display terminals without automatic adjustment function.

[0160] Figure 6 A flowchart illustrating a control method for a display terminal according to another embodiment of the present disclosure is shown.

[0161] Figure 6 The applications, electronic devices, display terminal 1, display terminal 2, and display terminal 3 shown can be referenced in the previous text. Figure 4 The description will not be repeated for the sake of brevity.

[0162] In this embodiment of the disclosure, the electronic device performs operations S601 to S603. In operation S601, a terminal group is created. In operation S602, display parameter values ​​are adjusted. In operation S603, display screen consistency is checked.

[0163] In this embodiment of the disclosure, operation S601 can refer to operation S401, and operation S602 can refer to operation S402. For the sake of simplicity, they will not be described in detail again.

[0164] In this embodiment of the disclosure, the electronic device performs display screen consistency detection in step S603 based on an anomaly detection strategy from the application and display data 1, display data 2 and display data 3 from display terminal 1, display terminal 2 and display terminal 3.

[0165] In this embodiment of the disclosure, the operation S603 display screen consistency detection may include: acquiring display data of the display screens of multiple display terminals based on adjusted display parameter values; and adjusting the display parameter values ​​of multiple display terminals in response to inconsistencies in the multiple display data.

[0166] In this embodiment of the disclosure, the consistency detection of the display screen is characterized by detecting the display effect of the display screens of display terminal 1, display terminal 2, and display terminal 3 included in the terminal group, in order to determine whether the display screens of display terminal 1, display terminal 2, and display terminal 3 are consistent based on the target display parameter values. If display terminal 1, display terminal 2, and display terminal 3 display screens based on the same target display parameter values, the display effects of display terminal 1, display terminal 2, and display terminal 3 may also be consistent.

[0167] For example, an electronic device sends target display parameter values ​​to display terminals 1, 2, and 3, but display terminal 1 does not receive these values, resulting in an inconsistency between the display effects of display terminal 1 and display terminals 2 and 3. Based on display data 1, 2, and 3, the electronic device determines that the display effect of display terminal 1 is inconsistent with the other display terminals. The electronic device can then send configuration parameters to display terminal 1, which can be the target display parameter value, thereby adjusting the display parameter values ​​of display terminal 1.

[0168] For example, the display parameter values ​​of display terminals 1, 2, and 3 are all adjusted to the target display parameter values. However, in the actual display process, the display effects of multiple display terminals may still be consistent. For instance, if an electronic device determines that the display effect of display terminal 1 is inconsistent with the display effects of other display terminals based on display data 1, display data 2, and display data 3, the electronic device can obtain the current actual display parameter values ​​of display terminal 2 or display terminal 3 and send configuration parameters to display terminal 1. The configuration parameters can be the current actual display parameter values ​​of display terminal 2 or display terminal 3, thereby readjusting the display parameter values ​​of display terminal 1.
